DMA
MRT Line 5(East‐West)
(1) Background and Necessity of the Project
The population of Dhaka Metropolitan Area (DMA) is rapidly increasing and has reached 13.6 million in 2011, a
40% growth since 2001. In particular, the population density is the highest among the mega cities in the world
standing at 43,500 persons/km2. It is expected that the city will greatly benefit from the development of public
transportation infrastructure network; however, the delay of its implementation is at a serious level hampering
urban economic activities. One of the major manifestations is the critical traffic congestion within the DMA, and
immediate actions for the development of transportation infrastructure are required.
To meet such needs, the Government of Bangladesh formulated a transportation master plan for DMA since 1959.
In 2005, the DMA Strategic Transportation Plan (STP), a master plan with a 20-year horizon from 2005 to 2024,
was formed under the technical assistance of the World Bank. The master plan has been reviewed periodically, at
approximately five years interval. In 2010, the Japan International Cooperation Agency (JICA) has conducted the
Dhaka Urban Transportation Study (DHUTS1) for the review of the order of priority of MRT lines that were
proposed in the STP.
Despite the aforementioned effort, the progress of the implementation of public transportation infrastructure
development has not been realized as planned in STP 2005. At present, MRT Line 6 funded by JICA and MRT Line
3 funded by the World Bank are being implemented.
Other recommended MRT/BRT projects have not moved
forward for implementation.
The serious delay of implementing public transportation
infrastructure development has exacerbated the traffic
congestion in DMA. To solve such serious traffic
congestion and ease the population density of the Dhaka
City Center, the Government of Bangladesh decided to
expand the Dhaka City limits through the development of
sub-city centers in suburban areas. Subsequently in 2013,
the Government of Bangladesh requested JICA to
conduct the study to revise the STP. Accordingly, the
Study on Revised Strategic Transportation Plan
(RSTP) is being carried out, in parallel to the METI
Study, aiming to induce the development of suburban
new towns by extending the MRT and road network for
the study area, i.e., Greater Dhaka area (RAJUK area:
1,528 km2). The RSTP is treated as “Upper Plan” of
the METI F/S for MRT East-West Line, therefore the
proposed alignment of East-West Line should be in

accordance with the proposed MRT network in the RSTP.
Figure S-1 presents the MRT/BRT network of RAJUK area
in 2035, which is proposed in the RSTP. The network
consists of six MRT lines and one BRT line. Among the
seven MRT/BRT lines, MRT Line 6, BRT Line 3, and MRT
Line 1 are recommended as priority projects to be
commissioned by 2025.
The MRT Line 5 (East-West Line), proposed by the METI
Study Team, based on the conceptualized Line 5, originally
planned as a circular line in the STP. The RSTP Team
extended the circular line eastwards to secure access for
commuters residing in the new residential area. The MRT
Line 5 is composed of two routes, i.e., northern route (Line
5N) and southern route (Line 5S) and is defined by the
METI Study Team as the East-West Line. In the RSTP
Study, Line 5N and Line 5S are proposed to be developed by 2035.
As shown in Figure S-2, the three priority lines proposed in RSTP are collectively defined as the north-south
corridor route; however, the priority lines for the east-west corridor have not been proposed yet. The METI Study
Team recommends the early implementation of MRT Line 5 that would establish an organic connection of the
MRT network and enhance the function of the planned urban transportation network.
(2) Basic Policies Established for Determining the Project Components
The following basic policies are established to determine the Project components:
1) Relation of the Plan Proposed in the METI Study with Revised Strategic Transportation Plan (RSTP)
The Revised Strategic Transportation Plan (2016–2035), which is currently formulated by the Dhaka Transportation
Coordination Agency (DTCA) with technical cooperation by JICA, is treated as the Upper Level Plan of the Study.
Based on this understanding, as a policy for determining the Project components, the demand forecast and
transportation network plan approved under RSTP will be applied for the formulation of the plan. Accordingly, the
Study result shall be consistent with the approved RSTP, and will be recognized as a long-term plan.
2) Demand Forecast
The results of the demand forecast for the Pre-Feasibility Study for Dhaka East-West Corridor are based on the
output of the demand forecast that was conducted by the RSTP Study Team. The RSTP Study Team identified the
demand forecast items required for the pre-feasibility study, output of the study, and analysis. Moreover, the
demand forecast model formulated by the RSTP Study Team was utilized for the METI Feasibility Study.
S-3
3) Selection of Priority Development Section of MRT Line 5
MRT Line 5 is planned to originate at Gabtoli Bus Terminal and shall consist of two routes totaling 35 km. The
north route passes through the north of Tejigaon Airport, Gulshan, Natun Bazar and stretches towards the east to
Bhulta township (Gabtoli-Bhulta Section, 23.2 km), while the south route passes through the south of Tejigaon
Airport and stretches eastwards to Aftab Nagar New Town (Gabtoli-Aftab Nagar Section, 11.8 km). The METI
Study Team recommends the phased development of MRT Line 5, starting with the implementation of the 16.2 km
section of the north route between Gabtoli and Beraid as Phase 1, since the demand forecast of the RSTP Study
concludes that this section has high demand. The RSTP proposes the full development of Line 5 by 2035, the
METI Study Team recommends the early implementation of the aforementioned section of Line 5N (Phase 1).
4) Partial Underground Structure for Phase 1 Section
The western section of Line 5N Phase 1 is proposed as a viaduct structure built above the right-of-way (ROW) of
the trunk road. On the other hand, a comparative study was conducted for the determination of the structure type
at the eastern side where the route crosses the cantonment area and business district of Banani and Gulshan. As a
conclusion, the underground structure is recommended over the viaduct structure despite the disadvantages of cost
implication and due to the following reasons: 1) expectation of higher level of surface land utilization in the future
following economic development; 2) avoidance of issues arising from viaduct structure passing near cantonment
area and minimizing resettlement; 3) applicability of shield tunneling technology; and 4) consideration on
preservation of landscape. The adoption of partial underground structure was discussed and agreed in principle in
the mini workshop meetings attended by DTCA, military representatives, and other related agencies.
5) Railway Technical Standard
The Bangladesh MRT Technical Standard (2014), which was prepared under JICA technical cooperation study by
DTCA and adopted in the detailed design of MRT Line 6, was applied as the basis of the basic plan and design of
MRT Line 5.
(3) Outline of the Project
1) Outline of the Route under the METI Study
The subject of the METI Study of MRT Line 5 is the Phase 1 section of north route that stretches 16.2 km and is
located between Gabtoli Bus Terminal and Beraid. The Phase 1 section consists of eight viaduct stations and four
underground stations. The depot is planned at the east end of the line located on a vacant swamp land which will be
a reclaimed land of 24.8 ha. A schematic diagram is presented in Figure S-4 indicating the station locations, and
horizontal and vertical alignment.

3) Demand Forecast
Table S-1 summarizes the estimated daily passenger and per hour passenger direction trip (PHPDT) from 2025 to
2055, which was estimated by the METI Study Team based on the demand forecast results provided by the RSTP
Study Team. The slight decrease of daily ridership between 2025 and 2035 indicates the transient phenomenon of
passengers taking newly developed alternative lines that will be commissioned within the 10-year period.

4) Rolling Stock
Environmental-minded train which adopts stainless/ Alminium structure, regenerative braking system, and VVVF
inverter system is applied. The basic specification of the proposed train is the same as that of MRT Line 6 trains. In
the opening year (2027), trains will operate in 3 min 50 s headway with 22 train sets of 6-car train including spare
cars. In 2055, headway will be shortened to 2 min with 38 train sets of 6-car train.
5) Depot and Workshop
The depot is located at the east side of Balu River along the Madani Avenue, which is the east end terminal of MRT
Line 5N, Phase1. The depot area is 24.8 ha that can accommodate 38 train sets of 8-car train, which are the required
number of train sets after extension of MRT Line 5N Phase 2. In the depot area, train storage facilities for 38 trains
of 6-car train, which are required for Phase 1 operation are constructed in this Project as well as the train
maintenance facilities, the Dhaka Mass Transit Company (DMTC) building, an administrative building, and
substations. The Operation Control Center (OCC) is planned to be accommodated in the DMTC building. As an
option, this depot, which is located about 6km east from Junction Station of MRT Line-1, can share with MRT
S-6
Line 1 and the trains for MRT Line 1 partial operation can be accommodated.
6) Railway System
(1) Power Equipment
The receiving substation of the railway company constructed in the depot receives electric power of 132 kV 50 Hz
by double system from the substation of Dhaka Electric Supply Co. Ltd (DESCO). The receiving substation
transforms electric power into 33 kV. In the traction substations at Mirpur 1 Station, Banani Station, Vatara Station
and depot, electric power for trains and electric power for services are transformed into 1500 V and 6.6 kV and
supplied to the feeder lines and electric rooms, respectively. Supervisory Control and Data Acquisition (SCADA) is
installed to monitor and supervise the electric rooms in each substation and electric room. Overhead catenary
system is adopted. Regenerative electric power storage apparatus are installed at the traction substation.
(2) Signaling System
For the Automatic Train Protection (ATP) System, Communication Based Train Control (CBTC) is applied. Also,
train detector uses the CBTC method. Automatic Train Supervision (ATS) and Automatic Train Operation (ATO)
are applied and driver-only operation is performed.
(3) Telecommunication System
By using optical fiber cable and transmission terminal, the Backbone Transmission Network, which connects OCC,
station, substation, and depot, is configured. Radio system for the dispatch control between OCC and train, and
closed-circuit television (CCTV) supervising system for overseeing the condition of stations are installed.
Passenger address system, passenger information display system, and clock system are installed in the platform area
of each station.
(4) Automatic Fare Collection
Contactless IC media is adopted as the ticket media. ISO/IEC 18092 (Type C) is selected for IC card because of high
security. Automatic gate of flap door type is selected because of high processing speed and high safety. Ticket
vending machine is not introduced and ticket media is sold at ticket window by person-to-person selling. The Felica
Type C Card has been introduced through JICA Technical Cooperation Project from 2011 as public bus network
ticket and widely accepted by the people in Dhaka.
(5) Platform Screen Door
A half height type is installed at the elevated station. In the case of underground station, a full height type is selected.
7) Project Cost
Table S-2 summarizes the Project cost estimate. Total construction cost including consultant cost is estimated at
BDT 149,492 million.

8) Preliminary Economic and Financial Analyses
The economic internal rate of return (EIRR) for MRT Line 5N Phase 1 is calculated as 16.2%.
The EIRR is higher than the 12% discount rate applied by ADB for their project appraisal; the benefit cost ratio
(B/C) stands at 1.5, and the NPV is about BDT 32.8 billion. The sensitivity analysis resulted in an EIRR of 12.0%
when the cost fluctuates by 20% upwards and benefit falls by 20%. According to DTCA, the opportunity cost
applied in Bangladesh is 16%, and the EIRR for MRT Line 5N Phase1 exceeds this opportunity cost.
The result of the cash flow calculation based on the financial analysis indicates a financial internal rate of return
(FIRR) of 2.7%. This value is rather low and the Project is considered not feasible for private sector funding. In the
event the expenses decrease to 20% and revenue increases to 20%, the FIRR still stands at 5.3%; thus, it was
concluded that the Project was not feasible from the financial point of view.
9) Socio-environmental Evaluation
Noise and vibration are expected to occur during the construction, however, when the Project is realized, the
reduction of carbon dioxide (CO2) emission as well as mitigation of air pollution can be achieved
For land acquisition and resettlement aspects, the impact is considered to be rather minimal since the route is
planned along the existing road for viaduct section, and the underground section was applied for the cantonment
area and for the congested central business district in Banani and Gulshan areas. The land where the natural gas
station at the corner of Mirpur Road is situated and the depot area need to be acquired.

Construction activities that are on the critical path are the tunnel works. In order to shorten the time of the tunneling
works, utilization of four shield machines launched from both ends of the up and down lines can be conceived.
However, this will require the construction of additional intermediate shafts at the underground section. This
method is considered to be technically unrealistic and would incur additional cost; thus, utilization of two shield
machines is considered, at present.
(5) Feasibility on Japanese Yen Loan and Project Implementation
The implementation of the Project by Japanese Yen loan is considerable based on the following situations: 1) The
necessity of the Project is confirmed by the outcome of the on-going RSTP Study which suggests the organic
connectivity with the north-south corridor which is currently being implemented, 2) The implementation of the
Project through private sector finance is financially unfeasible, 3) the first MRT Line 6 of Dhaka is being
implemented by Japanese ODA, and 4) the expectation of the Bangladeshi government towards Japanese
technologies and financial assistance is extremely favorable.
MRT Line 6 is currently in its bidding stage and the Government of Bangladesh expects the participation of
Japanese companies in the bidding for each package of MRT Line 6. The Government of Bangladesh is looking
forward to adopt MRT with Japanese specifications. Among them, the following five technical components are
globally recognized as having superior quality, and its application in the MRT Line 5 Project would realize MRT
construction under Japanese Technology.

(6) Conceived Project Implementation Schedule until Realization of the Project and Envisaged Risks Hampering the Realization of the Project
DTCA has identified the implementation of MRT Line 1 and MRT Line 5 as the next MRT projects and has
requested JICA in the end July 2015 to carry out the preparatory study for the two projects. Once JICA accepts the
request, a feasibility study is envisaged to be implemented in April 2016, and design work is expected to
commence in mid-2017. However, DTCA is being approached by the other donors, and the financial source of the
Project implementation is not finalized yet.

Chapter1 Overview of the Host Country and Sector
1-1
1.1 Economy of the Country and Financial Condition of the Government
1.1.1 Economic Condition of the Country
Bangladesh, a South Asian country with large population (142.3 million as of 2011 census, and 156.6 million as
reported in World Bank’s World Development Indicators (WDI) Little Database (LD) of 2015), has made
significant progress toward a more prosperous and pluralistic society in recent times. Although Bangladesh’s per
capita income is still relatively low (USD 1,096 in 2014 as reported in World Bank, World Development
Indicators, updated on 1st July, 2015, accessed through http://data.worldbank.org/indicator/NY.GDP.PCAP.CD,
accessed on 28th July, 2015) , its economy has grown at 6% annually for more than a decade; and its current gross
domestic product (GDP) is healthy at USD 158.8 billion (World Bank’s WDI LD of 2015). It may be mentioned
here that its per capita income was only USD 400 in 2004, which testifies that Bangladesh is growing at a very
fast rate. Because of this, leading economic research entities/think tanks like Goldman Sachs and JP Morgan
predicted high-potential economy for Bangladesh. In their Global Economics Paper No 134, “How Solid Are the
BRICS?” (Dec, 2005), Goldman Sachs introduced the Next 11 emerging economics and Bangladesh is included in
the list along with Korea, Indonesia, Mexico and Turkey.
Figure 1-1 GDP Forecast by Goldman Sach
Source: “Global Economics Paper No: 153 - The N-11: More Than an Acronym” and ”BRICs and Beyond”
The economy is increasingly led by export-oriented industrialization. The Bangladesh textile industry is the
second largest in the world after China. Bangladesh's textile industry, which includes knitwear and ready-made
garments (RMG) along with specialized textile products, is the nation's number one export earner, accounting for
USD 21.5 billion in 2013 – 80% of Bangladesh's total exports of USD 27 billion. It may be mentioned here that
current exports in this sector have doubled since 2004. Other key sectors include pharmaceuticals, shipbuilding,
ceramics, leather goods, and electronics.
Being situated in one of the most fertile regions on Earth, agriculture plays a crucial role, with the principal cash
crops including rice, jute, tea, wheat, cotton, and sugarcane. Bangladesh ranks fifth in the global production of
fish and seafood. Remittances from the Bangladeshi migrant workers also provide vital foreign exchange;
remittance amounted to USD 14 billion in 2014. Sector-wise share of the economy is as follows: 16% to

agriculture, 28% to industry, and 56% to services (2013 data, World Bank’s WDI LD of 2015). Yearly data shows
steady increase of secondary sector share.
Bangladesh is currently leveled as least developed country (LDC). The United Nations considers three indicators
for graduating a country from the LDC status, i.e., per capita gross national income (GNI), economic vulnerability
index (EVI), and human asset index (HAI). Bangladesh has already fulfilled the necessary conditions of EVI and
is nearly there in terms of the other two. The government expects that by 2018, the country will be able to meet all
three criteria.

As a consequence of rapid economic growth, the economy experiences rather high inflation rate. According to the
Bangladesh Bureau of Statistics (BBS) National Accounts Statistics (2013), annual average consumer price index
(CPI) inflation was 8.4% over the period from 2007 to 2013.
1.1.2 Financial Condition of the Government
Because of the rapid growth enjoyed by the country, government expenditure is also increasing. Government
budget is generally divided into development budget and revenue (non-development) budget. In general, revenue
budget includes government’s general expenditure and includes operation and maintenance (O&M) of existing
assets. On the other hand, development budget shows all projected expenditure related to a new project. For
example, a bridge is at first constructed with development budget and after certain years of operation, the bridge
will be transferred to the revenue budget, after which the O&M cost of the bridge will come from the revenue
budget. Usually, the projects under the development budget are listed in the Annual Development Program (ADP).
These two kinds of divisions can be explained in another way. The development budget expenditure is supported
by both domestic resources and foreign aid/loans. These include capital construction, incremental O&M finance,
and technical assistance like investigations and planning studies. The revenue budget covers recurrent expenditure
(like salary of employee), interest on development loans, and some non-development capital expenditures like
building construction.

Some of the key indicators from the financial year (FY) 2015-16 budget are shown as follows:
Total budget BDT 295,100 cr (about USD 36.9 billion)
Development budget BDT 102,559 cr (about USD 12.9 billion)
Expected external financing BDT 30,134 cr (about USD 3.8 billion)
Development budget in transport sector BDT 21,658 cr (about USD 2,707 million)
Transport budget as % of total development budget 21%
Some of the key financial indicators for FY 2014-15 (extracted from the FY 2015-16 budget document) are as
follows:
Investment (as % of GDP) 28.97%
Forex reserve USD 23.7 billion
Budget amount BDT 239,668 cr (about USD 30 billion)
Development budget BDT 80,476 cr (about USD 10 billion)
Average inflation 6.57%
From the above statistics, it can be concluded that transportation is one of the major thrust sectors of the
government as 21% of the total development budget is earmarked for the transport sector in FY 2015-16.
According to the Aid Scenario Report of 2013-14 of the Economic Relations Division (ERD) of Bangladesh
(original report is in Bangla), the foreign aid mobilization situation is as follows:

1.2 Description of the Targeted Sector
(1) Issue of Urban Transportation in Dhaka Metropolitan Area
Dhaka Metropolitan Area (DMA), which is the capital city of Bangladesh, is one of the largest mega cities in the
world with over 13.6 million people. In addition, it is the most overpopulated city of the world, since the
population density is 44,000 people / km2, which is ten times of the Tokyo-Yokohama Metropolitan Area.
Bangladesh's economy has achieved strong economic growth of about 6% in the past ten years. The population in
DMA, which is the center of growth, is expected to exceed 20 million in 2025 due to the population influx and the
natural increase from the rural areas. Currently, traffic congestion in DMA is chronic and heavy, and occurs
anywhere in the city because traffic is concentrated on the road, and development of transportation infrastructure
is inadequate. Also, the transportation mode is mixed on the same road such as public buses, rickshaws, and
automobiles.
The traffic jam causes economic losses estimated annually at about BDT 200 billion (2010) and this has become a
major barrier to future economic growth. Traffic pollution of exhaust gas and noise from the cars are also serious.
The development of urban public transportation system has become a pressing issue since this promotes the
improvement of DMA.
(2) Upper Basic Plan Related to Urban Transport
The Strategic Transportation Plan (STP) was formulated by the Bangladesh government with the cooperation of
the World Bank in 2005. The STP prepared the “urban transportation policy" which decided the target period of 20
years from 2004 to 2024. It also presented the establishment of an organization for project implementation and
maintenance, proposal for a mass rapid transit (MRT) with a total of 110 km that has three bus rapid transit (BRT)
routes and three MRT lines (Line 4, Line 5, and Line 6), and development of urban highway with a total of 330
km.
The Japan International Cooperation Agency (JICA) has conducted the Dhaka Urban Transport Network
Development Study (DHUTS) Phases 1 and 2 with Dhaka Transport Coordination Authority (DTCA) as
counterpart organization from March 2009. DHUTS conducted a review of the STP and traffic demand, selected
MRT Line 6 as the priority project, and verified the technical and economical validity of implementation of MRT
Line 6. Based on this, the ODA loan agreement for MRT Line 6 was signed in February 2013, and design and
procurement works are proceeding currently. In addition, BRT Line 3 is planed section between Gajipur-Airpor by
the World Bank (WB) and section between Airport–Jhimir the Asian Development Bank (ADB), whose design is
currently proceeding.
On the other hand, Government of Bangladesh has decided to enlarge Dhaka City to mitigate serious high
population density in the city center. RAJUK has been established to promote sub-urban centers development in
Greater Dhaka Area (RAJUK Area) of 1,584km2. JICA carried out the Revision and Updating of the Strategic
Transportation Plan (RSTP) from 2014. STP will be revised based on the latest survey results, and the next
1-5
priority project will be selected.
Chapter 3 presents the detailed background and overview of these basic plans.
1.3 Description of the Project Area
Dhaka is the capital of Bangladesh. The city is surrounded by rivers in all sides, namely: the Buriganga River in
the south and west, the Balu River in the east, and the Tugar River in the north and west. Dhaka experiences a hot,
wet, and humid tropical climate, with a distinct monsoon and short, dry, and cool winter.

UN Demographia (World Urban Areas 2015, Table 1-3) shows the greater Dhaka area population and density
1-6
compared with other major cities of the world. It can be seen from the table that Dhaka is the most densely
populated urban area in the world, followed by Mumbai. This table also shows that total area of Dhaka is much
smaller compared to other Megacities of the World.

Cycle rickshaws and auto rickshaws are the main modes of transport, with close to 400,000 cycle rickshaws
running each day. However, only about 85,000 rickshaws are licensed by the city government. Relatively low-cost
and non-polluting cycle rickshaws nevertheless cause traffic congestion and have been banned from many parts of
the city. Public buses are operated by the state-run Bangladesh Road Transport Corporation (BRTC) and by
private companies and operators; however, the service is inadequate and of low quality.
Dhaka City is administrated mainly by two city corporations, namely, Dhaka North City Corporation (DNCC) and
Dhaka South City Corporation (DSCC). However, these corporations’ mandates are rather limited, mostly
focusing on city roads and garbage collection. There are separate agencies for electricity, gas, water supply,
sewerage, and drainage. The land use plan of Dhaka City is controlled by another authority called the Capital
Development Authority (Rajdhani Unnayan Kartripakkha: RAJUK) was established on April 30, 1987. Its
principal mandate is to develop, improve, extend, and manage Dhaka City and its peripheral areas through proper
development planning and development control (source: www.rajukdhaka.gov.bd). On the other hand, the DTCA
is responsible for coordinating all transport-related issues of the Greater Dhaka area. It may be mentioned here
1-7
that all public buses are currently operated by the BRTC.
Although there is no official data released on the regional GDP of Dhaka, being the center of national economy,
Dhaka contributes about 15% of national GDP (as estimated by one local think tank, Center for Policy Dialogue
(CPD)).
Chapter2 Methodology of the Study
2-1
2.1 Contents of the Study
The public transportation network plan of Dhaka Metropolitan Area (DMA) has been updated every five years
since the Strategic Transportation Plan (STP) 2004 was formulated. Master plans, the Preparatory Survey on
Dhaka Urban Transport Network Development Project (DHUTS) 2010, and the Revision and Updating of Strategic
Transport Plan (RSTP) 2015 have been formed based on the STP. Target route of this study corresponds to the
MRT Line 5, proposed by RSTP, which is implemented in parallel at present. This Project aims to investigate the
feasibility of this target route.
MRT Line 5 has a length of 35 km. Priority route for early opening section for 16.2km is selected based on
demand forecast results. Issues of the routes are: (1) passing through Banani Cantonment, (2) first underground
construction in Bangladesh, and (3) financing.
Thus, feasibility study is carried out through technical, economical, and environmental aspects.

3.1 Background and Necessity of the Project
3.1.1 Background of the Project
The population of the Dhaka Metropolitan Area (DMA) is rapidly increasing and has reached 13.6 million in 2011,
a 40% growth since 2001. In particular, the population density is the highest among the mega cities in the world
standing at 43,500 persons/km2. It is expected that the city will greatly benefit from the development of public
transportation infrastructure network; however, the delay of its implementation is at a serious level hampering
urban economic activities. One of the major manifestations is the critical traffic congestion within the DMA, and
immediate actions for the development of transportation infrastructure are required.
The following projects are carried out in the past: Dhaka Master Plan (1959), Dhaka Urban Areas Integrated Urban
Development Plan (1981), Dhaka Metropolitan Area Integrated Transportation Plan (DITS) (1994), Dhaka Urban
Transportation Plan (DUTP), and Strategic Transport Plan for Dhaka (STP) (2005). Based on the STP study, the
Dhaka Urban Transport Network Development Project (DHUTS) was implemented in 2010 and the Revision and
Updating of Strategic Transport Plan (RSTP) was implemented in 2015.

(2) Summary of DHUTS1, 2
Under the Dhaka Urban Transportation Study (DHUTS1), the JICA Study Team will conduct the study with DTCB
as the counterpart agency with the aim of formulating the basic concept of urban development for DMA in 2025 as
well as formulating the projects for the JICA assistance program required in the medium to long term. The
objectives of the study are as follows:
・ To formulate the Urban Transport Network Development Plan integrated with the urban development plan of
DMA for the period up to 2025.
・ To draw the general outline of the urban transport projects to be implemented on priority basis based on this plan.
・ To clarify the roles of the project implementation agencies and the operation/maintenance/management agencies,
and to propose the development of their implementation capability.
・ To draw an outline of the feasibility study plan for construction of the urban transport system.
Based on the result of review of the STP study, DHUTS1 developed a policy strategic plan, infrastructure plan, and
master plan.
DHUTS1 proposed a mass transit system (MTS) development plan. The plan has created the MTS network plan and
proposed the priority development route. The MTS network plan, which allows the proposed urban development
plan, has been proposed in order to provide accessibility and mobility to the growing population in the future.
Table 3-2 Proposal of MTS Network
Source:DHUTS1 Report
From the Table 3-2, Line 4 to Line 8 show the mass rapid transit (MRT) corridor. Line 7 and Line 8 are part of the
transportation network that supports the urban development plan until 2050. These are lines for development in the
very long term. A comparative analysis of priority development line for MRT was conducted. The comparative
analysis was confirmed from five points, namely: 1) Urban Development, 2) Traffic Demand, 3) Technical
Acceptability, 4) Social and Natural Environment Impact, and 5) Project Implementation.
Based on the results of the comparative analysis, MRT Line 6 has a high comparative advantage. The reason is
3-4
because the transport demand is high and the road space is relatively wide that social issues such as land acquisition
and house relocation are less.
Figure 3-2 MTS Development Plan
Source:DHUTS1 Report
The MRT Line 6 Project was selected in DHUTS1 as a high priority project and it was agreed between the
Government of Bangladesh (GOB) and JICA that this Project will be further studied in DHUTS2 to confirm its
feasibility. The objectives of DHUTS2 are to conduct the feasibility study on the MRT Line 6 Project by confirming
the technical, economical, and financial viability of the Project as well as confirming the environmental and social
aspects. The study area covers the whole length of MRT Line 6, initially from “Uttara Phase 3 New Urban
Development” area to Saidabad but later extended to Bangladesh Bank and its surrounding area.

Constructing the 20.1 km length of MRT Line 6 may not be practical because the planned line requires a huge land
during construction period and immense cost. Hence, the following staged construction plan is recommended:
Stage 1: From Pallabi to Sonargaon including Pallabi Depot. Length will be 11.0 km plus 1.3 km access track to the
depot and it will include nine stations.
Stage 2: Extension to Bangladesh Bank from Sonargaon. Length will be 4.4 km and it will include four stations.
Stage 3: Uttara Phase 3 Development area to Pallabi. Length will be 4.7 km and it will include three stations.
(3) Summary of RSTP
The population growth of Dhaka is larger than expected in STP. RSTP is doing a review of STP from 2014. The
study area covers Gajipuru, Narayanganj, Manikukonji, Munshiganj, Narayanganj, and Norushinji districts.
Figure 3-5 Project Area (Left) and Study and Plan Area (Right)

[Objectives of the Project]
1) To revise and update the STP which was approved by the GOB in 2005.
2) To select plans and formulate a roadmap that would consist of high priority projects to solve current urban
transport issues.
[Goals of the Project]
・ The STP will be revised appropriately to promote an effective and efficient urban transportation development
in Dhaka, Gazipur, Narayanganj, and Narshingdi districts.
・ By implementing the urban public transportation projects to be included in the revised STP, economic growth,
alleviation of traffic congestion, and elimination of air pollution are expected.
・ A revised STP that will reflect short- , medium-, and long-term perspectives and a list of high-priority projects.

One of the current issues of Dhaka urban transport is that urban transport infrastructure developments had not been
carried out as scheduled in the STP. Thus, new urban developments at Purbachal, Eastern Fringe Area, and other
areas are delayed. One of the main reasons of the existing urban transport problem is the high population density in
DMA. Demands of transport, housing, shopping, and other facilities are too high at the limited area. Road capacity
is wasted due to poor traffic management and lack of coordination among the transport-related agencies.
[Correspondences of RSTP]
・ Formulation of the new urban structure concept for sustainable development of Dhaka
・ Formulation of the revised STP integrated with the new urban structure concept
[Urban Development Concept of RSTP]
The concept involves infrastructure development for implementing sub-urbanization to reduce population density in
the central business district (CBD). Satellite regional centers are connected with the urban core by MRT or bus rapid
transit (BRT). Each satellite regional center is connected by regional highways. Traffic management needs to be
implemented in CBD urgently for increasing the demand of private modes.

3.1.3 Current Condition and Future Forecast
This study is being conducted on the basis of the home interview survey and traffic volume survey and data
collection that have been carried out in the RSTP. The results obtained are summarized as follows:
(1) The Generated Traffic
The RSTP study conducted the house interview survey, cordon-screen survey, and road inventory survey. Based
on the result, the current generated traffic volume is about 30,000,000 trips/day. In addition, the generated
traffic volume in 2035 is about 55,000,000 trips/day. It was determined using a four-step methodology. The rate
of increase is 1.83 times. It has been calculated including the resident population based on the future land use of
urban development and industrial planning.

3.1.4 Necessity of the Project
MRT Line 5 (East-West Line) has become a second priority after the MRT Line 1 route for passengers based on the
PHPDT results from the demand forecast, excluding the currently ongoing route (MRT Line 6, BRT Line 3). The
MRT Line 1, BRT Line 3, and MRT Line 6 are all lines along the north-south axis, and there is not even one line
along the east-west axis. Therefore, MRT Line 5 can connect organically the north-south axis. As long as realized,
this Project is expected to eliminate traffic jam and further enhance the function of the urban transportation network.

3.2 Necessary Considerations for Decision of the Project Contents
3.2.1 Current Condition of the East-West Corridor and Preliminary Survey
Under the implementation of MRT Line 6 and BRT Line 3, which are part of the north-south corridor, there is no
specific progress about the development plan of the east-west corridor. One of the main causes is the existence of
control points on north-south direction which are Tejigaon Airport and Banani Cantonment as shown in Figure
3-13. Furthermore, swamp is spread on the eastern and western fringe of DMA. Therefore, the development of the
east-west corridor is relatively delayed.
On the other hand, it is important to connect the north-south corridor and east-west corridor from the viewpoint of
the public transportation network development. In addition, the future development of suburban areas such as the
1 million planned population in Purbachal and 0.5 million planned population in Savar, and the influx of people
from these areas to DMA need to be considered. Potential of MRT development is quite high.

Under the above circumstances, it was supposed to selecte the east-west corridor through the 1st screening and 2nd
screening. However, it is required to investigate the East-West line based on the RSTP proposal by JICA and
DTCA, because of the coordination with upper planning. METI study team follows the RSTP proposal. These
selections were conducted prior to finalization of the RSTP the public transportation plan. These ideas are shared
with the RSTP Team and assisted in the formulation of the public transportation network plan.

(2) Proposed East-West Corridor by RSTP
As mentioned earlier, MRT Line 5, combined with Alt-2 and Alt-4 routes was proposed by the RSTP.
Alt-2 (north route) passes through the Gabtoli Bus Terminal, Dar-Us-Salam Road, Mirpur Road, Banani
3-14
Cantonment, Natun Bazar, and Batara.
Alt-4 (south route) passes through the Gabtoli Bus Terminal, Mirpur Road, Panthapath, Hatirjheel, and Aftab
Nagar.
(3) Preliminary Consideration on RSTP Proposed Route
MRT Line 5, proposed by RSTP, is planned passing through the Banani Cantonment area which is considered as
sensitive area passing through by viaduct structure. On the other hand, underground option might be acceptable
because there is no effect on the building in Banani Cantonment during and after construction. In terms of
construction cost, however, cost of underground work will be 2 to 2.5 times higher than the viaduct works.
Therefore, the Study team recommends applying viaduct section in general, and the underground section shall
consider only for the critical/congested area for formulation of cost attractive scheme. Figure 3-15 and Table 3-5
summarize the survey results of North and South routes of MRT East-West Line.

3.2.2 Selection of the Study Route
Target route of this study for the MRT East-West Line should be selected based on future traffic demand forecast.
The objective is to derive a higher priority (high demand) route among MRT East-West Line routes by phasing. The
development schedule will also be decided.
(1) Phasing of MRT East-West Line
MRT East-West Line is formed by two routes, North route as Line 5N and South route as Line 5S, to the east from
Gabtoli Bus Terminal
Figure 3-16 MRT East-West Line Route

1) Demand Comparison of East-West Line North Route and South Route
Figure 3-17 shows demand forecast result of RSTP study. The results are about 44,000 passengers per km for the
north route in 2035 while south route has about 20,000 passengers. Therefore, north route has higher demand than
south route. North route will thus be selected as priority line.

2) East-West Line Priority Section of North Route
Though the North Route is selected as priority route of MRT Line 5, there are so far no residents found along the
route between Beraid and Bhulta of about 7km stretch. Large scale new town development is planned along the
section in future. On the other hand, the western section of MRT Line 5N between Gabtoli Bus Terminal and
Beraid of 16.2km has certain population along the route and expected high ridership demand for the beginning
stage. It is also expected to develop MRT network by construction of western section of MRT Line 5N together
with a few North-South Corridors.
Considering the above, western section between Gabtoli Bus Terminal and Beraid of 16.2 km stretch shall be
identified as Phase-1 of MRT Line 5N as top priority section.

3) Summary of Phasing of East-West Line
The western side of MRT Line 5N is defined as Phase 1 while Phase 2 is the eastern side. The target project of the
Study is then MRT Line 5N Phase1. In addition, the RSTP have set the whole MRT Line 5 to be opened in 2035.
(2) Future Traffic Volume Summary of MRT Line 5N Phase1
In the RSTP study, the future traffic volume of 2025 and 2035 has been estimated as shown in Table 3-6 below.
Therefore, the future traffic volume is assumed by growing the trip by 1.83 times from 2014 to 2035.

3.2.3 Mode Selection of MRT Line 5
The transport capacity is the most important factor for the purpose of selecting public transportation system. In
addition, it is necessary to consider the initial cost of infrastructure, operating speed, resettlement, O&M costs, and
the impact to the surrounding environment. In this section, referring to the demand forecast result for MRT
East-West Line, the candidate guide way transit systems, which have the capacity of several ten thousands of
passenger per hour are selected, and the describing the revalidation of MRT for selection of the Transportation
Mode.
(1) Conditions of Selection for Transportation Mode
Ultralow-floor tram type of the light rail transit (LRT) and automated guide way transit (AGT) are selected as
medium capacity guide way transit systems. Compared to this, the monorail and MRT systems are selected as large
capacity systems. The following Table 3-7 shows the overview of the results of system selection. The evaluation
method uses “+++”, “++”, and “+” markings to score the systems with Excellent, Good and Fail, respectively.

Although MRT has higher maximum speed and larger transport capacity than the other systems, it has large impact
on initial cost, resettlement, and the environment.

The estimated PHPDT is more than 27,000 passenger /hr according to the result of the demand forecast for the MRT
East-West Line from 2027 (Opening) to 2035. Consequently, MRT is selected based on the transport capacity in the
table. In addition, MRT Line 6 is planned as MRT and the choice of MRT is also appropriate considering the
technical aspects of management and maintenance of the rolling stock.

(3) Features of MRT
1) MRT Safety
a) Train Operation System of MRT
Safety management for train operation is based on telecommunication system and signaling system, and
trains are operated through the communication between the traffic dispatcher in the Operation Control Center
(OCC) and the driver. The driver operates a train based on the operation rule and the direction from the traffic
dispatcher.
Automatic Train Protection (ATP) system is provided to secure the safety of trains and the signal from the ATP
system is displayed in the cabin. The ATP system has the capacity to monitor and control trains in order to
observe the designated headway.
b) Train Operation
Practically, there are three methods for Electric Multiple Unit (EMU) driving, namely: 1) Driverless, 2) One-man
Operation (without conductors), and 3) Two-man Operation (with conductors). Recently, One-man Operation of
urban railway is used as the driving method. Although this operation requires facilities and equipment for securing
safety and service, it is significant for cutting off the labor cost.
c) Equipment for Securing Safety and Service
Typical facilities and equipment to ensure the safety of driving are listed as follows:
Station - Platform Screen Door (PSD)
EMU - ATP system, Automatic Train Operation (ATO) system, emergency brake device,
emergency alarm device, and automatic announcement system
2) Transport Capacity of EMU
Transport capacity of EMU is determined by car formation, congestion ratio, and headway, and Transport Capacity
is evaluated by the number of passengers of EMU. Generally, the size is 20 m long and 3 m wide and standardized as
JIS E 7103 (Rolling stock –General requirements of car body for passenger car). The capacity is as follows:
a) End Car
Capacity of end car is 45 seats and 108 standing; total capacity is 153 with a wheelchair space.
b) Middle Car
Capacity of middle car is 54 seats and 111 standing; total capacity is 165.
Capacity of 6-car formation and 8-car formation
・6-car formation (2 end cars and 4 middle cars)
3-24
Capacity: 153×2 + 166×4 = 970 passengers/train set
・8-car formation (2 end cars and 6 middle cars)
Capacity: 153×2 + 166×6 =1,302 passengers/train set
Congestion ratio during peak hour
The following Table 3-9 shows the congestion ratio and the condition of passenger cabin during peak
hour.
Table 3-9 Congestion Ratio and Condition of Cabin
Source:Japan International Transport Institute
Considering the convenience of passenger and train operation, the congestion ratio of EMU is ordinarily set to
150%-190% during train operation planning. The congestion ratio of MRT East-West Line is set to 180% taking into
account the headway, number of the train sets, and scale of the depot area. Under the condition of 180% congestion
ratio, the capacity of 6-car formation and 8-car formation will be 1,746 and 2,343, respectively.

3) Energy conservation of MRT
EMU is more energy efficient than automobile, MRT will contribute to energy conservation in transportation of
urban city.
Congestion Ratio Condition of Passenger Cabin 100% All passengers can sit and grasp strap or handrail.
150% Passenger’s shoulders touch each other. 180% Passenger’s body touches each other, but it is possible to read

a) MRT Line 6
The MRT Line 5N crosses the MRT Line 6 at CH 4k840 m of MRT Line 5N. MRT Line 6 is planned as an entirely
elevated structure, and the MRT Line 6 reduced level (RL) at crossing point is 21.663 m above mean sea level
(MSL).
In case that the MRT Line 5N is an elevated structure, it will pass over MRT Line 6, and the height of the MRT Line
5N Rail Level (RL) at this location needs to be 30.5 m or more above MSL.

Source: METI Study Team
b) Banani DOHS
The MRT Line 5N passes through the Banani DOHS at CH 8k140 m-8k440 m of MRT Line 5N. Six-storey
buildings are built continuously in this area. In case that the MRT Line 5N will pass in this area, it should not be
affected on these buildings.
3-27
The length of pile foundation of the 6-storey buildings is assumed to be 20 m deep. The distance from the edge of
the pile foundation to the tunnel upper edge should be more than the tunnel diameter 1D (= 7.0 m). Height of RL for
the MRT East-West Line in this area should be less than -24.7 m above MSL.
Figure 3-21 Control Point (Banani DOHS Area)
Source: METI Study Team
c) BRT Line3, Dhaka Elevated Expressway, Bangladesh Railway Line (Existing Railway)
The BRT Line 3 and Dhaka Elevated Expressway (DEE) are planned on the New Airport Road near chainage 8k500
m of the MRT Line 5N. In addition, the Bangladesh Railway (BR) runs parallel in the west side of the New Airport
Road.
In the crossing area with the MRT Line 5N, the BRT Line 3 and Bangladesh Railway are at the ground level while
DEE is elevated. In case that the MRT Line 5N is an elevated structure, it will pass over DEE (planned height of
3-28
road surface is 21.5 m above MSL). Therefore, the height of RL for the MRT Line 5N needs to be 30.0 m or more
above MSL.
In case that the MRT Line 5N is an underground structure, it needs to avoid the pile foundation of the DEE viaduct.
Although the length of pile foundation of the DEE viaduct is unknown, in this study, the length of pile foundation is
assumed to be 20 m and the height of RL for MRT Line 5N needs to be less than -24.7 m above MSL as well as
Banani DOHS.

d) Gulshan Lake
The MRT Line 5N passes Gulshan Lake at CH 9k400 m and 10k400 m of MRT Line 5N. In case that the MRT Line
5N is an underground structure, the thickness of overburden from the lake bed to the tunnel upper edge should be 1D
(= 7.0 m).
The Gulshan Lake has "an average depth of 2.5 m" according to the data ("Disaster Management Research Paper",
BRAC University, Bangladesh) coming from the field survey. Therefore, the depth of Gulshan Lake is assumed to
be 2.5 m in this study.
Figure 3-23 Control Point (Gulshan Lake)
Source: METI Study Team
e) MRT Line 1
The MRT Line 5N crosses MRT Line 1 at CH 10k900 m of MRT Line 5N. Although the detailed plan of MRT Line
1 is not yet decided at present, the underground plan of MRT Line 1 is mentioned in RSTP. Therefore, the
examination in this study is based on the assumption that MRT Line 1 is an underground structure.
In RSTP, since the priority of MRT Line 1 is higher than the MRT Line 5N, it is assumed that MRT Line 1 is
constructed in prior. Therefore, as for grade-separation crossing underground, MRT Line 1 is in the upper position
and the MRT Line 5N is in the lower position.
In this study, it is assumed that the MRT Line 1 station is constructed at the intersection and the MRT Line 5N
passes under the two-level station of MRT Line 1. The height of RL for the MRT Line 5N at the crossing area is
lower than -23.4 m above MSL.

3) Track Layout
The alignment plan is considered assuming the following track layout. As for station yard layout, it consists of an
elevated station with a pair of separate platforms serving two tracks and an underground station with an island
platform serving two tracks. Gabtoli Station has a scissors crossover for turnback operation. Mirpur 10 Station,
which is a junction station with MRT Line 6, has an emergency crossover considering turnback operation for
accident and trouble. Vatara Station is a junction station with the depot, which has a pair of separate platforms
serving four tracks. In addition, Beraid Station has a track layout in consideration of future extension to the
eastward.

1) Design Policy for Alignment Plan
a) Horizontal Alignment
The track alignment follows the center of existing road along the median as much as possible, and land acquisition
and house relocation are minimized by arranging the railway within the road right of way.
b) Vertical Alignment
In terms of vertical alignment, the existing ground level is set to a height of 8.0 m above MSL uniformly.
Moreover, in station section and general section, the required height (required depth) from ground level to RL is
shown in Figure 3-27 and Figure 3-28.

c) Transition Section
In the transition section from elevated to underground, the civil structure consists of elevated bridge, retaining wall,
excavated structure, box culvert, and shield tunnel. As shown in Figure 3-29 the area is divided in the section
"from the retaining wall to excavated structure", and the road traffic at the ground level is shut off. In case of vertical
gradient of 35‰, the length of “impossible area of crossing” is approximately 500 m.
In addition, the railway structure will occupy a width of about 10 m of the total road width in the transition section.
Based on the above, the position of transition section must be selected so as not to affect the existing road traffic as
much as possible.

d) Junction Station with Depot (Beraid Station)
The Beraid Station is a junction station with the depot, which has a pair of separate platforms serving four tracks
(two main lines and two depot access lines). In addition, the Beraid Station has track layout in consideration of
future extension.
The track layout for branching to the depot has either “grade separation” or “grade crossing”, as shown in the
following Figure 3-30. It is determined in consideration of the carrying capacity of the main line. Generally,
although grade separation can allow crossing without blocking the opposite train during train operation, it needs
facilities such as elevated bridge. On the other hand, grade crossing can minimize facilities although the carrying
capacity of the main line is reduced.
Although determined in consideration of the carrying capacity of the main line, grade separation is adopted in this
study so that obstruction of train operation in case of future extension may be prevented.
Figure 3-30 Branch Form
Source: METI Study Team
In consideration of a simple junction with the depot, Beraid Station is studied as an elevated station. In case that the
depot access line is considered as a grade separation (depot access line passes under the elevated main line), the
length of the depot access line needs to be about 320 m from the main line crossing part to the depot.

2) All Elevated Option
The horizontal alignment follows the existing median on the road as much as possible, except in the cantonment
area. Basically, vertical alignment should be based on the height of a typical elevated station; however, in order that
the MRT Line 5N passes over MRT Line 6 and DEE, the vertical height should be higher. Therefore, the height of
Mirpur 10 Station and Banani Station becomes higher at about 9 m compared with the typical elevated station.

a) Horizontal Alignment Plan
The salient points of the horizontal alignment plan are described below.
(i) Near CH 1k100 m, between Gabtoli Station and Dar-Us-Salam Station
In order to reduce land acquisition and house relocation, the minimum curve radius R=200 m shall be applied. Land
acquisition and house relocation (gas station), which are shown in the following Figure 3-33, are needed in this
section.

(ii) Near CH 3k040 m, between Dar-Us-Salam Station and Mirpur 1 Station
In order to avoid the relocation of an 8-storey building at the intersection corner, the minimum curve radius R=200
m is applied at Mirpur 1 intersection

(iii) Cantonment Area between Kochukhet Station and Banani Station
Although the horizontal alignment is constructed in the existing road space, there is no existing road which connects
Mirpur road with Kemal Ataturk Avenue directly in cantonment area. As mentioned above, in cantonment area,
comparison study of the three routes was carried our as shown in the following Figure 3-35.
3-39
Figure 3-35 Comparison Study of Routes in the Cantonment Area
Source: METI Study Team
The outline of each route is explained as below:
Route A
Kochukhet Station and Banani Station are connected with the shortest distance, and this route is the most desirable route in the view or railway technical design.
Although road width is9 m in Banani DOHS, the route, which needs removal of only the single-sided block facing this road, so that house relocation will be decreased.
Land acquisition in the area and house relocation of army chief’s residence and 6-storey buildings (13 buildings) in Banani DOHS are needed. This has the largest impact to the cantonment area and Banani DOHS among the three routes.
Figure 3-36 Route in Cantonment Area (Route A)
Source: METI Study Team
3-40
Route B
In order to avoid house relocation in Banani DOHS, the route is detoured in the north side of Banani DOHS.
Although there is no house relocation in Banani DOHS, some land acquisition of golf course is needed.
In order to reduce house relocation, S-curve with minimum curve radius of 200 m is applied from the golf course to Banani Station. Seven buildings are relocated at the intersection corner.
Banani Station is situated farthest from the New Airport Road among the three routes. Therefore, the accessibility with BRT Line 3 will be worse.
Figure 3-37 Route in Cantonment Area (Route B)
Source: METI Study Team
Route C
There is the Shadheenata Shoran Road in the south side of Banani DOHS, which crosses the east and west sides of the cantonment area. In order to avoid house relocation in Banani DOHS, the route is detoured on this road.
Road detours largely in the south of Banani DOHS. Therefore, route length between Kochukhet Station and Banani Station is the longest among the three routes.
In order to reduce house relocation as much as possible, the minimum curve radius of 200 m is applied.

As mentioned above, although a comparison study of the three routes at the cantonment area was done, each route
for the all elevated option has merits and demerits depending on the viewpoint. Therefore, it is hard to determine the
superiority or inferiority of each route. Accordingly, in this study, Route B, with comparatively small impact on
Banani DOHS and the lowest cost, is adopted. However, in terms of the validity of the alignment from the viewpoint
of train operation, further study is required.
3-42
(iv) Vertical Alignment Plan
The height of each station section is decided and the gradient of station section is set to be level. Then the
vertical alignment connects the height of each station.
In order that the MRT Line 5N can pass over MRT Line 6 and DEE, the vertical height should be high enough in the
crossing areas. Therefore, the height of Mirpur 10 Station and Banani Station becomes about 9 m higher compared
with the typical elevated station.

3) Partial Underground Option
Similar to the all elevated option, the horizontal alignment follows the existing median of the road as much as
possible, except in the cantonment area. In order to reduce the impact on the cantonment area, the vertical alignment
passes through the underground in this area. Four stations from Kochukhet Station to Natun Bazar Station are
underground stations. The other eight stations are elevated stations.

Station is located at intervals of about 1 km in consideration of horizontal alignment, vertical alignment, and
junction with other routes. The station locations from Gabtoli Station to Mirpur10 Station are the same as previously
mentioned in the elevated plan. The station locations are shown in the following Table 3-14.

a) Horizontal Alignment Plan
The horizontal alignment is the same as that of the all elevated option except in the Banani DOHS section.
In Banani DOHS section, the MRT Line 5N runs underground. Therefore, the alignment plan does not need to take
the building block into consideration. In this section, the curve can be reduced and the alignment gets smoother
compared with the all elevated option.
Figure 3-41 Route near Banani DOHS (Partial Underground Option)
Source: METI Study Team
b) Vertical Alignment Plan
As for the elevated section, it is the same as the all elevated option mentioned earlier, i.e., the height of station
section is decided and the vertical alignment connects the height of each station.
As for the underground section, in this study, water leakage from tunnel is gathered together in the station section,
and vertical alignment connects the station section with a gradient of more than 2‰. Vertical alignment does not
form "valley shape" between stations. In addition, the gradient of the station section is level.
Although Kochukhet Station and Gulshan 2 Station are typical two-level underground stations, these stations have
depth of more than three-level underground stations since Banani Station and Natun Bazar Station have nearby
control points. The vertical alignment at the pile foundation section of Banani DOHS can also be made shallower
than the current plan if underpinning construction method is used. However, in this study, not underpinning
construction method but general construction method, which secures a distance of more than 1 D from the pile edge
to the tunnel upper edge, will be applied.
【 About Transition S 】ection
Since the transition section needs a width of about 10 m and road traffic is blocked out in the section of 500 m,
selection of its location should be considered carefully. In the selection of the location of the transition section,
"wide road" and "location which avoids heavily trafficked main intersections" are selected. In this study, two
3-45
transition sections are needed.
Transition Section at WestPoint
Kochukhet Station is planned as an underground station so that the cantonment area may not be affected, and the
transition section is set between Mirpur 14 Station and Kochukhet Station. The width of road (Mirpur Road) in this
section is about 35 m, and since there are no heavily trafficked main intersections, transition section can be set.
In addition, the location of Mirpur 14 Station is decided based on the length of the transition section, and it is located
at about 60 m in the west side compared with the all elevated option.
Figure 3-42 Location of Transition Section (between Mirpur 14 Station and Kochukhet Station)
Source: METI Study Team
Transition Section at East Point
The transition section at the east point is set between Natun Bazar Station and Vatara Station due to the following
reasons:
The depth of Banani Station is about 34 m from the ground because of the pile foundation of Banani DOHS. In addition, since Gulshan Lake is between Banani Station and Gulshan 2 Station, the transition section cannot be set here. Therefore, Gulshan 2 Station must be planned as an underground station.
Since Gulshan Lake and Bir Uttam Rafiqul Islam Avenue are between Gulshan 2 Station and Natun Bazar Station, the transition section cannot be set here. Therefore, Natun Bazar Station also must be planned as an underground station.
Since the width of Vatara Road is about 30 m and there are no main intersections between Natun Bazar Station and Vatara Station, the installation of transition section is possible.
The location of Vatara Station is decided by the length of the transition section, and it is located about 695 m in the
east side compared with the all elevated option.

【 About Relation with MRT Line 】1
The MRT Line 5N and MRT Line 1 cross in separated grade underground. In this study, since the priority of MRT
Line 1 is higher than the MRT Line 5N, it is assumed that the MRT Line 1 is constructed in prior. Therefore, as for
grade-separated crossing underground, MRT Line 1 is in the upper position and the MRT Line 5N is in the lower
position. For this reason, the Natun Bazar Station of the MRT Line 5N is located deeper than normal, and the length
of the transition section is longer.
It is necessary to decide by examining further studies whether MRT Line 1 or MRT Line 5N will be located at the
upper position, in consideration of various viewpoints such as the relationship of each route and station, the junction
method of shortcut line in the case of sharing depot, and workability.

3.2.5 Transportation Accessibility Plan (MRT Line 6, BRT Line 3, MRT Line 1)
(1) Development Objects for Intermodal Facility
Transport mobility is employed everywhere from the origin to destination.
Figure 3-45 Image of Transport Mobility
Source:The investigation team made a report based on the Ministry of Land, Infrastructure, Transport and Tourism
In this study, transport mobility has to promote through smooth transit to other modes at MRT stations. Therefore, it
is important to reduce the transfer resistance for the smooth planning of a transfer facility. Also, it should be
promoted modal shift from existing transport modes to the proposed MRT. Especially, transfer resistance is said to
occur in the following cases:
「・The generation of up and down transit movement, ・The distance of transit movement is more than 200 m」
3-48
(2) Junction Station with MRT Line 5
At present, the MRT Line 6 and BRT Line 3 projects are promoted in Dhaka. Also, RSTP identified the MRT Line 1
as a priority project. The three routes are being implemented and planned, and these routes run through Dhaka from
north to south. Thus, the Junction Stations with MRT Line 5N are most important considering the current traffic
condition in Dhaka. However, traffic node is important in order to construct the future transport network of Dhaka.
Moreover, MRT Line 5N is considered necessary in order to connect with BRT Line 3 for the efficient transit city
planning in Dhaka. Thus, the node is shown with “MRT 6”, “BRT 3”, and “MRT 1”. The proposed station location
and transition to other lines are also shown.

(3) Classification of Junction Station
The junction station is classified as "parallel type", "cross type", or "separation type". The type of junction station
should consider the difference of horizontal distance and vertical distance and the restrictions for the type of station
connection. Table 3-15 describes the characteristics of different type of Junction Stations.
Table 3-15 Types of Junction Station
Type Image Horizontal Distance (Advantages)
Vertical Distance (Advantages)
parallel type
Same Platform
It has minimum distance because movement is only in the platform.
None
Parallel Platforms ・Although mobility in the platform has short distance, it is changed by the attachment of stairs and the presence and absence of concourse. (separation platform : a side)
・The mobility in the platform has the maximum distance to transfer the edge spacing.
・The mobility has long distance to transfer to the platform. (separation platform : longitudinal)
・Transfer distance is the difference of mutually positioned platform (either location of platform or move over a side)
・The distance of mobility is decided by the difference of the platform level of both lines.
cross-type
Cross type
(The station overlaps bilaterally)
There are necessary transfers to the platform, concourse, and passage but they are short distances.
The distance of mobility is decided by the difference of platform level.
・In general, the mobility entails short distance in the case of interlaced opposite platform and island platform.
T cross type
(The station closes bilaterally)
Although the distance of transfer to the platform needs to move edge spacing, the distance to another platform is short distance.
L cross type
(The station closes bilaterally)
Mobility of platform needs to transfer from edge spacing, and it is maximum distance.
separation type
Separation type
Although transfer station is near, the stations are connected not only by crossover but also by passageway.
・There are necessary transfers to platform, concourse, and passage.
・Due to the large share of passage, the horizontal distance is maximum distance.
Although the range of mobility is decided by the difference of platform level, in general, separated station has long vertical distance.

(4) Facilities for Smooth Transit
In order to transfer smoothly, “improvement of a facility’s scale”, “convenience of facilities”, “ease to follow a
facility”, and “comfort of facilities” have to be considered. Table 3-16 compiles the major points of provision of
3-51
smooth transit facilities,

Study Point Examination Item Contents for Discussion Related User
Improvement of a facility’s scale
・Securing the capacity of facility
・ Optimization of facility’s configuration
・The subway station cannot secure the scale for facilities because it is built the space is under the road.
・Measures for capacity during rush/peak period and the method for appropriate facility location should be considered.
・Commuter
Convenience of facilities
・Reduce the transfer resistance
・ Reduce the complicated passenger flow
・The resistance increases because it is not only far for transit, but also there are corners of passage and up and down stairs.
・Thus, it is considered to reduce the resistance method or alleviate the resistance method.
・All users
・Commuter
Clear guidance toward destination
・Easy to understand guide display
・A subway has complex architecture because of constrained condition of the spaces.
・Thus, it might be difficult to understand for an inexperienced user, so information signs for proper guidance should be considered.
・Business
・ Non-commuters, e.g. shoppers
・Commuter
Comfortability for facility users
・ Create the comfortable space
・In the future, it is necessary to develop not only a mere subway station but also comfortable spaces as a community area where people can gather should be considered in the future spaces.

(6) Formulation of Transport Node Improvement Related to Smooth Transfer Movement
Smooth transfer movement requires four functions. The four functions are called “accessibility”, “information
guide”, “queue”, and “transportation node”. The necessity of each function in the different locations is described in

(7) Large-scale Development of Station Plaza/Improvement of Station Plaza
There is a need to develop sub-urban transportation hub at MRT terminal stations to protect the traffic flow to the
3-53
city center. It is also necessary to develop public transportation hubs in city center such as junction stations, city
market, and business center for smooth transit. In a suburban station plaza, construction of a terminal facility
should be secured during the planning phase and it should be set as an aggregation of existing transport. Moreover,
it is necessary to focus on the protection of traffic flow to the city center.
Station front is considered not only a transportation node but also an amenity such as a place to gather citizens. Thus,
the characteristics and necessary services of the station front in the future should be considered.

3.2.6 Train Operation Plan
The train operation of MRT Line 5N is planned taken into account the road traffic condition during peak hours in
Dhaka City area and the performance of MRT, in addition train operation is planned the required train formation,
number of train sets and frequency of train operation for each year.
(1) Maximum Train Operation Speed
The maximum train operation speed of the Line 5N was set to 100 km/h in consideration of civil structure, average
distance between stations, and energy conservation.
(2) Speed Restriction Curve
Speed restriction at curve section is designed for the prevention of rollover accident and comfortable ride.
1) Cant to be Installed for Curves of Railways
The speed restriction of the curve section is set according to the following basic formula, although the speed limit
for radius below 230 m is set referring to other case.

(4) Turnback Time of Station
There are scissors crossing for turning at Gabtoli and Vatara terminal stations. Turnback time at the terminal stations
is different between Gabtoli and Vatara because the train needs shunting to the lead track in Vatara. Turnback time
depends on the headway, turnback facilities, passengers boarding/alighting time, point switching time, and drivers’
transit time.
1) Turnback Time at Gabtoli Station
Scissors crossing is installed at the turnout of Gabtoli Station for the turnback of the main line. Trains pass through
the scissors crossing before arrival at the platform in this layout.
a) Turnback Operation using One-sided Platform
The required minimum passing through time at the scissors crossing is 1 min and 30 s and in addition to that, more
time for getting on and off the train for passengers should also be added. In case of headway of 3 min 50 s, the
stopping time for train getting on and off can be set to 2 min 20 s.

(2) Rolling Stock of the MRT East-West Line
From ease of maintenance and energy conservation measures points of view, composition of the recent mainstream
commuter trains in the urban area in the world is as follows:
a) The stainless steel, which has corrosive resistance, is used as the main material of the car body
because painting is not needed.
b) The bolsterless bogie, with few component parts and reduced wear parts, is adopted.
c) As main motor, an AC motor, which does not have contacted parts and is maintenance-free except for
the axle bearing, is adopted. Main circuit is controlled by inverter.
The rolling stock of MRT Line 6 follows the Technical Standards of the MRT in Bangladesh, and is adopting the
mainstream composition of the latest commuter train such as Variable Voltage Variable Frequency (VVVF) inverter
control and regenerative braking system. The specification of this train is the typical urban commuter railway of
recent years.
For the MRT East-West Line, the rolling stock whose basic specifications are similar to that of MRT Line 6 is
proposed. By using similar rolling stock, facilitating the technology transfer from the MRT Line 6 engineer and
information exchange for improvement of maintenance technology with the MRT Line 6 engineer are expected.
The basic specifications of the rolling stock proposed for the MRT East-West Line is shown in Table 3-28 below.

3.2.8Depot Plan
(1) Basic Concept of the Depot Plan
The main function of the depot is train storage and train maintenance. The periodical maintenance can be
categorized to light maintenance and heavy maintenance. Light maintenance is carried out every several days or
every several months. Heavy maintenance is carried out every four years or every eight years. For heavy
maintenance, the large-scale facilities for dividing vehicles into the body and bogie, and disassembling parts are
needed. The depot of the MRT East-West Line is planned based on the following concept:
a) The depot is constructed nearby or along the railway line of MRT Line 5N Phase 1. The depot
mainly consists of the train storage tracks, a main workshop (factory), the inspection tracks for the
train maintenance and inspection, a DMTC operation center, an administrative building, a depot

control room, the office buildings, the warehouses, and a traction substation. In the DMTC operation
center, OCC which controls the train operation of the MRT East-West Line is installed.
b) When the MRT Line 5N Phase 2 is extended, the capacity of the abovementioned depot is expanded
and the additional trains of MRT Line 5N Phase 2 are stored and maintained in the depot.
c) When MRT Line 5S is extended, the route length of the MRT East-West Line becomes relatively
long. Thus, by taking into account the efficiency of train operation, it is recommended that an
additional satellite depot which has storage tracks and light maintenance facility for the additional
trains of MRT Line 5S is constructed along the railway line of MRT Line 5S. The facilities for heavy
maintenance are not installed in this satellite depot. Heavy maintenance of the additional trains for
MRT Line 5S is carried out at the main workshop in depot.
d) A connecting line between MRT Line 6 and the MRT East-West Line is not constructed. Trains of the
MRT East-West Line are stored in its own depots and heavy maintenance is carried out in the main
workshop.
(2) Location
During the site survey, five candidate sites of the depot area could be found nearby or along the railway line of
Line5N Phase 1. Based on the evaluation described in Table 3-30 below, candidate No. 5 is selected as the location
of the depot of the MRT East-West Line.

(4) Required Capacity of the Depot
According to the train operation plan, the number of required train sets for transport service of MRT Line 5N Phase
1 is 22 train sets (6-car train) in the opening year and 38 train sets (6-car train) in the future (2055). During the
construction of MRT Line 5N Phase 1, a depot which has a capacity for storage and maintenance of 38 (6-car train)
train sets which is required in the future is constructed.
Meanwhile, the depot capacity itself will be expanded in a phased manner in accordance with the extension of MRT
Line 5N Phase 2 and MRT Line 5S. According to the estimation shown below, in the ultimate stage of the MRT
East-West Line, the depot shall have the capacity of heavy maintenance for 23 trains of MRT Line 5S, in addition to
the capacities for storage and maintenance of the 38 train sets (including 8-car train) of MRT Line 5N Phase 2. This

Furthermore, the depot of the MRT East-West Line can be shared with MRT Line 1 and the trains for MRT Line 1
partial operation can be accommodated in the depot of the MRT East-West Line. Although MRT Line 1 partial
3-69
operation is expected between the vicinity of the airport and business district, the planned location of the MRT Line
1 depot is far from the section of this partial operation. Therefore, stabling and maintenance of trains are problems
for the MRT Line 1 partial operation. Sharing of the depot of the MRT East-West Line can contribute to the
implementation of the MRT Line 1 partial operation. There are three plans to accommodate the MRT Line 1 trains
in the depot as follows:
a) From the start of operation of MRT East-West Line to when the 1st trains come around 2039, 22
train (6-car train) sets are accommodated in the depot which has a capacity of 36 trains (6-car train).
If the length of train of MRT Line 1 is less or equal to 6-car train, 16 train sets can be stored in the
depot in this period.
b) If MRT Line 1 adopts 8-car train, a depot which adopts a layout of the ultimate stage and has a
capacity of 36 trains (8-car train) is constructed in the construction period of phase 1 of MRT
East-West Line 5N.
(8) When the number of trains for partial operation of MRT Line 1 is more than 16 train sets or when the
depot construction of MRT Line 1 is overdue, a layout which exceeds the capacity of the depot for
ultimate stage is applied. When the transport service of Line 5N Phase 1 is started, 36 train sets of MRT
Line 1 can be accommodated in the depot. Even if the number of train sets of MRT East-West Line is
increased in future, at least 20 train sets of MRT Line 1 can be stored in this depot.Depot Layout
The maintenance tracks are planned so that train maintenance can be carried out for 8-car train. Since the MRT
East-West Line has a lot of opportunity to add train, a space and exclusive track for train installation by trailer are
prepared in the depot. Facilities shown in Table 3-32 below will be installed in each track.

3.2.9Railway System Plan
(1) Power Equipment
1) Power Receiving System
In Bangladesh, in order that the electric power supply meets the demand, electrical infrastructure improvement such
as installation of electric generating plant and improvement of electric power distribution network shall be
undertaken. The electric power sector in Bangladesh is divided into three categories, i.e., power generation, power
transmission, and power distribution.
Area: 24.8 ha Storage capacity: 38 train sets (8-car train)
Area: 26.4 ha Storage capacity: 58 train sets (8-car train)
3-72
The MRT East-West Line receives electric power from the power distribution company. Seven distribution
companies exist in Bangladesh and the two companies of Dhaka Electric Supply Company Limited (DESCO) and
Dhaka Power Distribution Company (DPDC) are distributing electric power to Dhaka. The MRT East-West Line is
located in the area covered by DESCO.
Figure 3-58 Demarcation of Distribution Companies
Note) DESCO: Dhaka Electric Supply Co. Ltd DPDC: Dhaka Power Distribution Company Ltd BPDP: Bangladesh Power Development Board WZPDC: West Zone Power Distribution Company Ltd NWZPDP: North West Zone Power Distribution Company Ltd SZPDC: South Zone Power Distribution Company Ltd REB: Rural Electrification Board
(REB distributes electric power to the rural area of the whole country) Source: CRM Practices in the Electricity Distribution Sector in Bangladesh (LIRNEasia, March 2013)
Generally, there are two methods of power supply for railway system, namely:
a) The railway company receives electric power from the power distribution company at its respective
traction substations directly.
b) The railway company receives electric power from the power distribution company at its receiving
substation and distributes electric power to the respective traction substations.
The former system is cheap compared with the latter system, and can respond flexibly to future extension. However,
the former system requires that the electric power company has many suitable power lines and the power situation is
stable. From the viewpoint of power situation in Dhaka, the MRT East-West Line applies the latter system. The
power receiving method from DESCO shall take into account of the electric power system and its stability, and will
be decided by further discussion with DESCO. Along the MRT Line 5N phase 1 route, DESCO has the substations
at Mirpur and Bashundhara which is located at about 2 km north from Vatara.
Bangladesh (Except area of REB)
Dhaka (Except area of REB)
3-73
2) Traction Substation
The required electric power for the electric railway system consists of two categories. One is to operate the train,
which is called the “electric power for train”. The other category is referred to as the “electric power for services”,
which is required for the electromechanical equipment (lighting, ventilator, air conditioner, lift and escalator, office
machinery) in the station, substation, and depot.
In each traction substation, the electric power for train is transformed from 33 kV into DC 1,500 V and is supplied to
the feeder lines. And the electric power for services is transformed into 6.6 kV and is supplied to the electric rooms
in the station and depot by double system.
Generally, the installation interval of the traction substation of the railway system of the DC 1,500 V is about 4~5
km. Since the route length of MRT Line 5N Phase 1 is about 16 km, three traction substations are installed in the
Minpur 1 Station, Banani Station and Vatara station. And another traction substation is installed at the depot.
3) Transmission and Distribution Plan
・ An electric power supply adopts reliable double system. It has composition which can operate usually
even if one system breaks down.
・ The receiving substation of the railway company constructed in the depot receives electric power of 132
kV 50 Hz by double system from the substation of DESCO. The receiving substation transforms electric
power into 33 kV.
・ In the traction substations at Minpur 1 station, Banani Station, Vatara station, and depot, electric power
for train and electric power for services are transformed into 1,500 V and 6.6 kV and supplied to the
feeder lines and the electric rooms, respectively.
・ In the electric room, in order to distribute low voltage power to the electrical facilities in the station, AC
6.6 kV which is received from the high voltage line is transformed into 220 V and 440 V.

4) Supervisory Control and Data Acquisition (SCADA)
Centralized monitoring and supervision for the electric system is carried out at OCC through the installed SCADA
system. SCADA system can monitor and supervise the equipment installed in the receiving substation, traction
substations, and electric rooms by using the remote supervision and control system which is connected through the
communication line.
5) Catenary System
In accordance with the Technical Standards for the MRT in Bangladesh, a simple catenary system or a feeder
messenger catenary system is adopted.

6) Regenerative Electric Power Storage Apparatus
For the countermeasure against abeyance of the regenerative breaking system of the train, and by taking into
consideration the electric power condition of Dhaka, installation of the regenerative electric power storage device is
proposed. The regenerative power storage device has various types such as the one which uses a lithium-ion battery,
an electric double layer capacitor (EDLC), and a nickel metal hydride battery.
This apparatus can store the regeneration electric power of the surplus currently which was consumed as heat
heretofore. And it can recycle electric power by emitting electric power at the needed time. Furthermore, it
prevents regeneration loss, provides voltage drop compensation, and executes peak cut at transfer substations.
7) Power Receiving Capacity
The basic units of electric power consumption of train of Japanese railway in 2013 are shown in Table 3-36 below.
These Japanese railway companies are operating the energy conservation commuter trains which are similar to the
proposed trains of the East-West Line in this Project. Basic unit of electric power consumption of train is calculated
by dividing the electric power consumption (kWh) by car-running kilometer (car-km).

The basic unit of power consumption of train in the East-West line is assumed as 1.93 kWh/car-km.
In the above table, in the case of Odakyu Electric Railway Co., Ltd., the energy conservation commuter train which
has VVVF inverter and regenerative brake accounts for the large proportion of 97.5% of fleet in 2013. Since the
trains of the East-West Line also adopt VVVF inverter and regenerative brake, it is expected that the basic unit of
electric power consumption of the East-West Line can achieve 1.75 kWh/car-km of the same level as that of Odakyu
Electric Railway Co., Ltd. However, in the case of the MRT East-West Line, the electric power consumption of
auxiliary machines including air conditioner shall be increased by taking into account the differences of climate
between Dhaka and Tokyo. When it is assumed that the electric power consumption of the auxiliary machine is 10%
of the whole consumption of train and the workload of auxiliary machine in Dhaka is 200% of that of Tokyo, the
basic unit of electric power consumption of the MRT East-West Line is calculated by the following formula:
3-76
Basic unit of electric power consumption of the MRT East-West Line
= (1.75 x 10% x 200%) + (1.75 x (1-10%)) = 1.93 kWh/car-km
b) Power Demand of Station and Depot
In the case of an at-grade station which is equipped with facilities such as lighting, signaling, telecommunication,
Automatic Fare Collection (AFC), and Platform Screen Door (PSD, the power demand is assumed to be 250
kW/station. The power demand of an elevated station is calculated at 350 kW/station by the addition of the lift and
elevator (100 kW) to the at-grade station. The power demand of an underground station is calculated at 1,150
kW/station by the addition of the lift and elevator (100 kW), air conditioning (600 kW), and additional lighting (200
kW) to the at-grade station.
The power demand of the depot is assumed to be 1,800 kW which includes the maintenance facility in the main
workshop (1,000 kW), lighting and air conditioning of main workshop (500 kW), lighting in the depot area (300
kW), and others (100 kW).
c) Power Receiving Capacity
The surplus ratio of substation and power factor are assumed as 1.2 and 0.9, respectively. The required capacity of
the receiving substation of MRT Line 5N Phase 1 in the future is calculated as 29.0 MVA (all elevated option) and
33.3 MVA (partial underground option).

2) Signaling System for the MRT East-West Line
Table 3-37 Signaling System of MRT East-West Line
System Description ATP, ATC The MRT East-West Line adopts ATP with the moving block system.
When a driver ignores or misunderstands the signal or sign, ATP brings the brake into operation automatically if the train advances in defiance of danger, starts erroneously, or exceeds the speed limit. ATP is the system to check and control the train speed based on the speed condition information which is continuously directed in accordance with the location of a preceding train and the condition of railway section.
As for the blocking system, CBTC which is a global trend in new route construction is proposed.TD Since ATP adopts CBTC, it is proposed that TD also adopts CBTC. IL In the station and depot which is equipped with the point machine, the interlocking system
which interlocks the point machine and the route is installed.
Route setting of the main line and the tracks in the depot is basically performed by remote control from an operation control device in OCC. The operation panel installed at each station and depot can be operated manually for the individual route setting in each station and depot.
3-78
ATS The MRT East-West Line adopts ATS. ATO The MRT East-West Line adopts ATO with driver-only operation. On-board ATP for speed control
On the approach tracks of the depot and the storage yard in the depot, the trains are operated manually since neither ATO nor CBTC is installed. (On-board ATP for speed control, train collision prevention, and overrun prevention are installed.) Manual train operation using wayside signal is adopted at the maintenance yard in the depot.

communication from the train to OCC, communication between OCC and passenger is available.
CCTV System OCC staff can supervise the condition of station yard by CCTV supervision system. The monitoring cameras are installed at the station concourse, escalator exit, ticket window, and platform. The train driver checks the situation of the boarding and alighting of passengers with the image of the camera, and operates the door to close. In the depot, the cameras are focused on the draw-out track, storage tracks, train-wash line, and approach tracks. And the train movement in the depot is supervised in the depot control room. The video picture taken with the camera is digitized and recorded on a digital video recorder.
PIS, PAS, PIDS PIDS is the visual display service which provides the information with regard to a train entering a platform and departure train, as well as the clock time and special announcement at each station. PIDS is installed in the platform area.
The broadcasting of information regarding the train operation and emergency broadcasting are carried out from OCC to the passengers in the station yard and trains. The broadcast is performed with the voice or the recorded sound of an OCC staff to all or specific stations and trains. Also, manual broadcasting at each station can be performed.
Clock System Clock is installed at OCC, mechanical rooms in the whole line, stations, and depot. A master clock which has high reliability and becomes the basis of other clocks in the station is installed in OCC. And other clocks are synchronized with this clock.

(4) Automatic Fare Collection (AFC)
1) Merit by Introduction
The AFC system consists of contactless IC card, contactless IC card handling system, ticket vending machine,
automatic gate, ticket office machine, central server, network facilities, and cash handling equipment.
By introducing the AFC system, work saving of station staff and minimizing the station area as well as preventing
an illegal ride are expected. Moreover, the AFC system can manage fare revenue and collect the passenger
utilization data which is helpful for improvement of transport service.
According to the Technical Standards for the MRT in Bangladesh, the AFC system which is introduced in Dhaka is
being requested as follows: AFC is a convenient system for passengers.
- To secure the mutual availability with the contactless IC cards which are used for the other
public transport system in Dhaka.
- To be designed by taking into account passengers’ safety and convenience, especially the
aged, children, expectant mothers, and handicapped, into the design.
2) General Outline of the System
Table 3-40 General Outline of the System
System Description Ticket Media Magnetic ticket and IC ticket, which the machine can read/write, are used. In recent years,
contactless IC ticket, which has multiple functions, high security, and can quickly process ticket gate passage, became the mainstream. In the IC ticket system, IC card is used for seasonal pass and stored fare card while IC token is used for single journey ticket.
Contactless IC media is used for railway AFC system.
The contactless IC card used for railway AFC can be NFC Type A which carries IC chip of ISO/IEC14443 and NFC Type C which carries IC chip of ISO/IEC 18092.
Although both types have several versions in terms of the differences of data retention value and transmission speed, the security level of Type C is higher than that of Type A.
Automatic Gate As for the automatic gate for railway, there are three types, namely: flap door type, retractable type, and turnstile type. The processing speeds are 60 persons/min for the flap door type, 40 persons/min for the retractable type, and 30 persons/min for the turnstile type.
3-80
The retractable type has the highest prevention against illegal passenger followed by the turnstile type, and then the flap door type. However, when a passenger is caught by the door, the flap door type is the safest.
Ticket Vending Machine (TVM)
TVM sells various kinds of railway tickets and charges the money to the IC card. TVM shall have the function to discriminate bank notes in order to detect and reject fake or unacceptable bank notes.

Table 3-41 AFC System for the MRT East-West Line
System Description Ticket Media Contactless IC media is applied.
As the same as MRT Line 6, ISO/IEC 18092 (Type C) is selected for IC card. Automatic Gate Flap door type is selected in order to fulfil the processing speed requested by the technical
standards.
Reader/writer of an automatic gate shall be multitype so that the media which includes any type of IC chip can be accepted. When ticket media is IC card, the fare shall be collected by the automatic gate from the amount of the deposited money in the ticket media.
Ticket Vending Machine (TVM)
Among the bank notes of Bangladesh, most of the notes which will be used to purchase the train ticket is worn currency. It is difficult to discriminate worn bank notes by the machine. Since the ability requested by the technical standard cannot be fulfilled, TVM is not introduced and ticket media is sold at the ticket window through person-to-person selling.

(5) Platform Screen Door (PSD)
1) Merit by Introduction
There are two types of PSD, namely, full-height PSD and half-height PSD.
Full-height PSD Half-height PSD
Source: METI Study Team
By introduction of PSD, the accident of passenger falling from the platform to the track can be prevented. Moreover,
the accident of passenger touching the moving train at the platform edge is also prevented. Therefore, the number of
station staff to secure the safety on the platform can be reduced.
3-82
In the case of underground station where the tunnel is not refrigerated, the full-height PSD can keep the air
conditioning in the platform. Thus, the platform can be air-conditioned efficiently and economically by PSD. In the
case of underground station where the train passes, the full-height PSD can protect passengers from train wind.
2) Basin Concept of PSD for the MRT East-West Line
The half-height PSD is installed in the elevated station from the viewpoint of securing the safety on the platform. In
the case of underground air conditioned station, full-height PSD is adopted to secure the safety of passengers and
save the energy of air conditioning.
The train configuration of the MRT East-West Line is 6-car train during MRT Line 5N Phase1 and 8-car train will
be added in MRT Line 5N Phase 2. The train which has four doors per one side of car is being proposed. Allocation
of PSD door shall conform to the number and position of the doors of the train.
3) System Configuration of PSD
The PSD consists of the following systems:
a) Fixed barrier (wall) and movable barrier (wall)
b) Entrance door for driver
c) Control and monitoring system
d) Safety system including sensor, alarm, and display
e) Power supply system including uninterruptible power supply system
The PSD needs to have a combined function with the ATO, train antenna, and CCTV on the platform.
3.3 Outline of the Project Plan
3.3.1 Basic Policy for Determination of the Scope of the Project
(1) Basic Policy of Dhaka City and Outline Design
In the implementation of MRT Line 6, elevated structures for the whole line were accepted. The MRT Line 5N has
been planned to build elevated viaducts like in MRT Line 6, and to cross the cantonment area between Kochukhet
Station and Banani Station where many five-storey residential buildings, an 18-hole golf course, and sensitive
facilities are compactly located. Demolition and land acquisition are required to construct viaduct structure for
MRT Line 5N. The precedent report says that the area is so wide that there are no alternate routes to avoid it, and
it is agreed by the Study Team. Therefore, an underground tunnel method has been envisaged to avoid land
acquisition, demolition of residential buildings, and environmental issues. There are no experiences of shield
tunnels and underground stations in Dhaka which may be far more expensive than the elevated viaducts. However,
it becomes acceptable to adopt better plans based on the recent powerful economic growth even though they are
costlier. At the mini workshop of this study, DTCA has curiously asked how large is the gap between the amount
of all elevated option and partial underground option.
3-83
(2) Comparative Study of All Elevated Option and Partial Underground Option
The Study Team presented the schematic drawing of shield tunnel and underground station to DTCA, and then
compared the preliminary project costs between them as shown in Table 3-42.
Table 3-42 Comparison of Cost Estimation
Source: METI Study Team
Although the all elevated option is more economical than the partial underground option, it was foreseen that there
will be great difficulties in negotiating with the army to acquire the land in the cantonment area, demolish
residential buildings, and manage the environmental issues. Therefore, both DTCA and the Study Team have
agreed to adopt the partial underground option. DTCA deems it to be financially feasible and the Study Team

considers that it is more suitable for the Project to mobilize the technique, cooperation, and financial assistance
from Japan for the tunnel method. The comparison of merits and demerits between the all elevated option and the
partial underground option is shown in Table 3-43.
In addition, full underground option was additionally assessed based on the request of DTCA. The results are
complied in Appendix 4, including the cost estimate, construction plan, project implementation schedule,
economic and financial analysis results. This is for reference only and the Study team recommends that the
Partial-Underground option is the optimim scheme for MRT Line-5N, Phase-1.

3.3.2 Specifications of the Applied Facilities
The structures of the elevated and underground options are shown in Figure 3-61 below. Applied facilities do not
have any effect on road traffic under both elevated and underground options. Regarding the elevated structure, two
lanes are occupied at all sections during construction. On the other hand, regarding the underground structure,
although two lanes are occupied at the station, there is no effect on road traffic at the other section thanks to the
shield tunnel.

3.3.4 Issues and Solution to Apply the Proposed Technology and System
(1) Shield Tunnel
Underground construction period is extended compared with viaduct construction. Application of the double
shield machine, considering that tunnel construction is the critical path, is also considered in order to meet the
early commercial operation because it is desired to open the line as earlier. However, Banani Cantonment exists at
the tunnel section. Furthermore, although shaft should be prepared for the shield machine installation, it is unclear
where to find it. It is a quite sensitive issue; therefore, the details should be discussed in the next feasibility study
stage.
(2) Traffic Management during Construction of Underground Station
In general, road is open for the construction of the underground station, and the station width will be occupied on
the road for the construction. The western side of Gulshan 2 Station, which is the narrowest section in this study,
3-87
is 20 m wide, and the station width is also 20 m. Therefore, road is completely blocked during construction, if no
appropriate construction method is taken into account. In fact, it would be a big problem to block the road, which
is the center of the office area of Dhaka. Considering the chronic traffic congestion in the area, half of the station
should be completed first without completely closing the road. After that, road decking panel will cover the
completed part. Traffic can pass through it, therefore it can contribute to traffic management.
(3) About the anti-inundation measures of the transition section and the underground station
In cases that flood and local severe rain occur, the serious damage to affect a human life may occur, besides
paralysis of traffic by the flood from the opening of a subway.
As the opening of subway, there are pithead of transition section, station entrance, and ventilation opening. And
the following is mentioned as main anti-inundation measures.
Pithead of transition section => Installation of flood wall or pithead gate for anti-inundation
Station entrance => Mount-up of station entrance, installation of water shut plate or watertight door
Ventilation opening => Installation of flood prevention machine, installation of the ventilating tower which
has an opening in high position

(4) Coordination with Other Projects
Total coordination of transport project is poor, but many projects are ongoing in parallel including this Project.
Flyover is now constructed in DMA without coordination, so overlapping with other flyover at the road space
above usually happens. Original planning does not go well. Regarding the crossing section at Natun Bazar, which
is the junction station between MRT Line 1 and MRT Line 5, for example, the vertical alignment of MRT Line 1 is
underground. In addition, MRT Line 1 is the priority line in RSTP. Therefore, the vertical alignment of the
East-West Line will pass under the MRT Line 1. However, if vertical alignment of MRT Line 1 becomes an
elevated structure at this section, the alignment of MRT Line 5 will be revised again and there is an effect on cost
estimation. In this case, the total project cost will decrease because depth will be shallow. But the worse case may
happen in other projects without coordination. Accordingly, it is important to properly coordinate with RSTP and
to collect information.
Chapter4 Evaluation of Environmental and Social Impacts
4-1
4.1 Analysis on the Environmental and Social Impact
The current situation regarding the environment and social aspects of the Project is briefly described below.
Geology and Soils
Dhaka lies in the extreme south of the Madhupur Tract, which is situated in the central-eastern part of Bangladesh.
The planning area is covered mainly by the Pleistocene Madhupur Clay, a yellowish brown to highly oxidized
reddish brown silty clay, and by Holocene sediments in the south, west, and east, which is made up of alluvial silt
and clay, and marshy clay and peat.
Earthquake Risk
Dhaka City falls in seismic zone II based on the seismic zoning map of Bangladesh as show in Figure 4-1. It is
classified as being on the upper end of the scale for moderate risk. Significant damaging past earthquakes has
occurred in and around Bangladesh, and damaging earthquakes of moderate magnitude occur every few years.
Faults and lineaments that have occurred due to tectonic movements appear along the edge of the Dhaka Terrace

Subsidence
According to Higgins (InSAR measurements of compaction and subsidence in the Ganges-Brahmaputra Delta,
Bangladesh, Stephanie Higgins, University of Colorado Boulder, CSDMS meeting of 2014), land subsidence in
Dhaka occurs at the rate of 0 to > 10 mm/yr, and is likely related to groundwater abstraction. Variations in the rate
of subsidence correspond to local variations in shallow subsurface sediments. According to some surveyed data
(Updated Environmental Impact Assessment (EIA) of MRT Line 6, 2015), subsidence rates in the order of 2-4
mm/yr are typical in the Project area.
Groundwater
The total groundwater abstraction from licensed production wells operated by the Dhaka Water Supply and
Sewerage Authority (DWASA) and private (mainly industrial) operators is around 700 million cubic meters
(MCM) per year. In addition to DWASA tube wells, there are more than 1,000 privately managed deep tube wells
that are primarily unlicensed and for which no abstraction data are available. Some deep tube wells reach greater
than 400 m.
Groundwater levels throughout the city have fallen drastically over the last 15-20 years. Data tabulated by Zahid
et al. (Excessive Withdrawal of Groundwater for Urban Demand of Dhaka City: Emergency Measures Needs to be
Implemented to Protect the Aquifer, Anwar Zahid, M Qumrul Hassan, M Abdul Karim and M Ashraful Islam,
Ground Water Hydrology, Bangladesh Water Development Board, undated) indicated that groundwater levels
have fallen from 23 to 47 m in three areas of the city from 1980 to 2007.
Groundwater quality data as reported in the updated EIA of MRT Line 6, 2015, shows the following:
High arsenic level in some shallow well
Deep well water seems very fresh
Drainage
A generalized drainage map for Dhaka is shown in Figure 4-2. This map shows the main drainage channels for the
Project area as follows:
Drainage is not yet fully developed in the north and east side.
The section from Pallabi to Mirpur is drained through the Digun Khal (Rupnagar) and the water flows north
and is discharged through the same pump station to the Turag River.
The section of the MRT Line 5 alignment near Mirpur drains through the Kallyanpur Khal and into the
Buriganga through the Kallyanpur Khal Pump Station.
Begum Bhari Khal drains the area in the vicinity of Sonargaon and Shahbagh toward the east to the
Shityalakya River.

Surface Water Quality
The surface water quality (except rivers) in Dhaka City shows many pollutants according to the Updated EIA of
MRT Line 6, 2015.
Dissolved oxygen (DO) is generally high, near saturation, in all the lakes, but near zero in the khals.
pH in the lakes is neutral to slightly alkaline, depending on the season; whereas it is slightly acidic in the
khals, approaching the pH lower limit of the Department of Environment (DOE).
Conductivity and total dissolved solids (TDS) are consistently low in the lake water. The khal contains
twice the amount of TDS, and conductivity is two times higher than the average of all lake samples. These
are indicators of inorganic salts present in water from human activity, which are not generally present in the
lake samples.
Chemical oxygen demand (COD), total suspended solids (TSS), turbidity, and coliform bacteria are high in
the lake samples during the dry period, but are reduced significantly in the wet season.
The following Figure 4-3 shows the water quality hot spots of Dhaka City.

General Weather Conditions
Dhaka experiences a hot, wet, and humid tropical climate. The city is within the monsoon climate zone, with an
annual average temperature of 25 °C (77 °F) and monthly mean temperature varying between 18 °C (64 °F) in
January and 29 °C (84 °F) in August. Nearly 80% of the annual average rainfall of 1,854 mm (73 in) occurs
between May and September.

Air Quality
Air quality is measured directly as suspended particulate matter as total SPM and PM10, the fraction smaller than 10
µm, nitrous oxides (NOx), sulfur oxides (SOx), carbon monoxide (CO), and lead (Pb). DOE sets ambient standards
for four of these pollutant parameters as shown in Table 4-1.
Table 4-1 DOE Ambient Air Standards (µg/m3)
Land Use Category SPM SO2 CO NOx
a. Industrial and mixed 500 120 5000 100
b. Commercial and mixed 400 100 5000 100
c. Residential and rural 200 80 2000 80
d. Sensitive 100 30 1000 30
Source: METI Study Team
According to the Updated EIA of MRT Line 6, 2015, for pollutants that have specific limits set by DOE (SPM, CO,
NOx, and SO2):
All but one (92% of total 12 sampling points) of the monitoring locations produced daytime SPM values in
excess of the residential standard, and six locations (50%) exceeded the standard for commercial and mixed
land uses. Nighttime values are within the limit set by DOE for commercial and mixed land uses.
The DOE NOx standard for commercial and mixed land uses was exceeded in eight out of 12 samples
(66%) for both day and night values.
The CO standard for commercial and mixed land uses was exceeded in seven out of 12 samples (58%)
taken during daytime hours, and in six out of 12 samples (50%) taken at night.
SO2 is generally within the limits set by DOE, with none of the monitoring results exceeding the residential
standard. Daytime SO2 levels are generally 66% higher than nighttime levels.
Air quality is better during the rainy season (second data set), with values typically 50-70% lower than the
dry season results.
Noise Level
Noise is measured in weighted decibel units, typically in 10-minute averages, but may also be in 1-hour, or
day-night (24-hour) averages. DOE ambient noise criteria are shown in Table 4-2.

Source: METI Study Team
In general, Dhaka is a noisy city, at least along the roadside. According to the Updated EIA of MRT Line 6, 2015,
only six locations out of the 40 measured sites have a noise level of less than 60 dB. On the other hand, there were
26 locations where noise levels exceeded 70 dB. In Mirpur 10, noise level is 70.7 dB, while it is 72.7 dB in
Shahbagh.
Protected Areas
The DOE designation of an Ecologically Critical Area (ECA) is intended to identify an environmental protection
zone. There is no protected area or ECA within or near the Project area.
Flora and Fauna
Because Dhaka City is urbanized, there are few natural forest areas remaining. Still, the vegetation of Dhaka City
has a variety of indigenous and exotic species especially in parks and gardens. Although there are varieties of
mammals and birds existing in Dhaka, none of them are endangered or protected.
Land Use
Dhaka City’s growth is moderated and directed according to land use classification and zoning set up by the
Capital Development Authority (Rajdhani Unnayan Kartripakkha: RAJUK). RAJUK publishes land use map
referred to as “Comprehensive Detailed Area Plan on RS Mauza [base] Map” which both fixes and designates
land uses. The current Dhaka Metropolitan Development Plan (DMDP) was prepared in 1997 for the period
1995 to 2015. However, the new DMDP for 2015 to 2035 is now under preparation. A draft version is available
from July 2015. The newly proposed land use map is shown in Figure 4-4 below.

Transport Assets
Growth of transport vehicles is shown in Table 4-3. Overall growth of passenger vehicles is 49% over the last five
4-8
years. Recurring growth is gradually falling from 13% to 3.3%, which shows that the saturation level (0% growth)
may be reached in the next five years. Congestion on roads and lack of road space for driving and parking will
force people not to buy more vehicles.
Motorcycles (76.4% growth over the last five years) will supersede cars and other 4-wheelers soon. Many old
buses and mini buses are operating on the roads and cause air pollution. They are planned to be replaced in phases.
Growth in the public transportation system is not high.
Growth of goods vehicles is very high. In the last five years, their combined growth is 177%. The number of
trucks has increased 2.5 times over the last five years. While the increase in freight traffic is a sign of prosperity,
maintenance of the national and regional highways needs to be improved, and development of new regional roads
is needed to cope with the challenges of growing freight traffic.

4.2 Environmental Improvement Effects by the Project
The Project will mainly and significantly contribute in reducing the travel time and also vehicle operation cost. In
turn, this will help in reducing traffic congestion. There are a number of environmental benefits associated with the
Project. These are briefly explained below.
Positive Impacts: Green House Gas Reduction
The Project mitigates climate change by bringing about a reduction in greenhouse gas emissions in comparison with
a base case scenario without the Project. The estimate of emissions reduction due to the Project is based on reduction
of polluting cars operation.
Positive Impacts: Air Quality Improvement
As the car and bus operations will be reduced due to modal shift, the emission of CO, SOx and NOx will also be
reduced.
4.3 Project Influence on Environmental and Social Sectors
4.3.1 No Build Alternative
The Project is considered within the framework of the Revised Strategic Transport Plan (RSTP) of 2015 through a
series of planning decisions. The RSTP is a long-term plan for the target horizon of 2035. The MRT Line 5 is the
only east-west connection among the seven proposed and ongoing MRT and BRT lines. A “No Build Alternative”
is simply not acceptable as without this MRT Line 5, no effective network can be realized.
In the economic analysis of this Study, it was mentioned that with the implementation of MRT Line 5, the travel
speed will increase from 10 km/h to 35 km/h. Also, it was found that yearly economic benefit from MRT Line 5
will be around BDT 20 billion/year. It was also confirmed that the Project is economically viable.
4-10
Based on the above discussion, it can be concluded that “No Build Alternative” is far less logical than the
implementation of MRT Line 5.
4.3.2 Anticipated Environmental Impacts
Environmental assessment involves weighing the likelihood of an event and the magnitude of its impact on an
affected resource. Environmental impacts can be minimized in the planning and design of the Project, and
mitigation measures can be applied during construction and operation phases. A detailed impact assessment of the
MRT Line 5 Project is expected to be carried out in the later stage of the Project during a full-scale feasibility study.
In this Study, anticipated impacts are briefly discussed.
Noise
Noise issues during the construction phase are significant, in particular during depot land development, while noise
emissions during operation are less significant. Construction of foundations and piers, and erection of precast
viaduct sections, will generate moderate noise. On the other hand, construction of underground section will not
generate any noise at the ground level.
Noise levels during construction along the alignment are not expected to exceed the adopted standard. Nonetheless,
it might be exceeded at times. The following mitigation measures are proposed to reduce noise impacts from
construction:
Use heavy equipment with built-in noise abatement, especially pavement breakers, crawler cranes,
excavators, and concrete cutters;
Construct temporary noise barriers between noisy activities and noise-sensitive receivers;
Place equipment on construction and casting yards as far away from noise-sensitive sites as possible;
Construct walled enclosures around especially noisy activities or clusters of noisy equipment;
Combine noisy operations to occur in the same time period, if possible;
Avoid nighttime activities where there is sensitivity to noise, such as hospitals; and
Provide noise-dampened equipment such as quiet and enclosed air compressors and properly working
mufflers on all engines.
The noise from train operation depends on track type, rail curvature, track structure, and speed. The transit noises
generated by MRT Line 6 for ballast less track, and with 2 m parapet, are 62.4 dB for train speed of 45 km/h at radius
of 160 m and 57.9 dB for train speed of 95 km/h at radius of more than 500 m. Thus, it can be stated that noise is not
an issue for straight sections, but it is more than 60 dB (mixed area daytime DOE limit) for curved sections.
However, by placing noise- and vibration-proof track like Mass Spring System (MSS), it is possible to reduce the
generated noise by 3 to 5 dB. Thus, it can be said that transit noise can be managed with the proper arrangements.
For underground section, there is no issue of noise both during construction and operation phases.
Vibration:
Vibration is measured in Vibration decibels (VdB) and in Peak Particle Velocity (PPV, mm/sec). It may be noted that
there is currently no vibration-related standards in Bangladesh.
4-11
Vibration during operation is not a significant issue; vibration will be at the higher side at curve sections, but this can
be mitigated by introducing noise- and vibration-proof tracks like MSS. On the other hand, normal construction
equipment does not cause severe vibration except for sand compaction or dynamic compaction equipment. At this
stage of the Project, it is not certain which equipment will be used. Hence, it is suggested that this should be
investigated in more detail in the feasibility study stage of the Project.
For underground section, there is no issue of vibration both during construction and operation phases.
Air Quality
Air emissions can be generated during construction of the viaduct and stations by equipment operations and
entrainment of dust along roadways near construction sites, yards, and haul routes. Operation of the transit system
and stations do not generate air pollution.
Air quality impacts associated with construction activities should be minimized by the following measures:
Spray water at work sites and on unpaved surfaces within fabrication yards;
Cover and/or wet down materials onsite;
Loads will be covered during transportation of loose sand, aggregate, and spoil materials by truck;
Provide washing facilities at the gates of casting yards and materials storage sites, if necessary, to remove
mud from wheels and undercarriages; and
Provide certification that construction equipment brought onto the job complies with exhaust emissions
standards, and assure equipment is properly maintained.
Traffic Congestion
Although traffic congestion can be significant during operations in the vicinity of stations, it is more significant
during construction of viaduct and overhead station as well as underground station construction (as those are
constructed using open cut method). Traffic congestion in construction zones can be addressed through proper
traffic management planning such as:
Reducing demand by promoting the use of public transportation;
Restrictions on rickshaws entering the main thoroughfares;
Debottlenecking of traffic flow at key intersections;
Partial restrictions on roadside parking and loading at peak traffic periods; and
Diversion of private and bus traffic around the construction zones.
For underground section, there is no issue of traffic congestion for tunnel construction.
Drainage and Water Quality
This impact is mainly associated with the construction phase. Drainage design is aimed at preventing standing
water and flooding in the vicinity of work sites by providing positive drainage to the point of outfall. Poor water
quality at the point of discharge or open water can affect public health and aquatic ecosystems. The main impact
during construction is due to suspended solids entrained in runoff that can soil surfaces and clog drainage systems.
However, with proper drainage plan, this impact can be minimized easily.
4-12
Visual Impact
The elevated portion including viaduct and stations can have some visual impact. However, it is very subjective
and can be minimized by introducing motifs and colors to blend the imposing structures into its surroundings.
For the underground section, there is no issue of visual impact during construction and operation phases.
Other Negative Impacts
There are possibilities of some other impacts at insignificant level such as groundwater, solid waste, tree cutting,
and occupational health. Impacts from these can be mitigated easily.
4.3.3 Land Acquisition
(1) General Condition
In the earlier chapters, it was explained that the north route of MRT Line 5 (Line 5N) will be considered as
priority route of MRT Line 5, while within this MRT Line 5N, Phase 1 is marked as the section between Gabtoli
and Beraid for immediate implementation. This section passes through the congested areas including cantonment
area. Various types of options are considered including partial underground at the central portion. A very rough
assessment is carried out for the land requirement and estimation of the market value.
In general, for straight portion of the alignment, there is no need for land acquisition as the viaduct will be placed
at the center of the road. The expected width of viaduct is about 10 m and most of the alignment will pass through
roads much wider than 10 m. Impact, however, arises from the curve section, as the minimum allowable curve
radius is 200 m. Stations are proposed in such a way that there should not be any land requirement. It is to be
noted that, entry/exit from the elevated stations might need some minor land requirement, which can also be
confirmed during the detailed design stage.
Three elevated options are considered for passing through the cantonment area. A separate land acquisition cost is
estimated for each of the alternatives. However, it is to be noted that apart from this section, there are land
acquisition required at other locations of the alignment.
Also, costs for depot are estimated. In addition, as for reference, a brief estimate of the land acquisition has also
been made for the south route of MRT Line 5 (Line 5S) as well.
(2) Between Gabtoli and Mirpur 1
The RSTP Team proposed the alignment to follow Dar-Us-salam Road as shown below (yellow line). However,
alternate analysis was carried out for Mazar Road (green line).
4-13
Figure 4-5 Alignment of Mazar Road and Dar-Us-Salam Road
Source: METI Study Team
In both cases, there would be land acquisition. However, as Mazar Road is very narrow (average road width is
only 13 m), a large number of buildings need to be demolished at the station site as shown below.

The demolition of buildings in the southern and northern ends of the road will also be massive, as respectively
shown below.

On the other hand, for the yellow line, land acquisition is required only in the southern end as shown below. Here,
Purbachal CNG Station and CNG Conversion Factory will be affected along with some tin shade structures.

For Dar-Us-Salam option, there will be a land requirement of around 2,500 m2 at the gas station. The estimated
cost of compensation is around BDT 5,610 million.
(3) Cantonment Area
For the elevated viaduct, three options are considered for the cantonment area as shown below, namely: (a) yellow
line through Banani Defense Officers Housing Society (DOHS), (b) green line through the golf course, and (c)
blue line through the existing road.
Figure 4-10 Alignment in Cantonment Area

Yellow Route
The yellow route passes through the Banani DOHS, where the road width is only 9 m, so the entire one side of the
block has to be removed. In addition, there are few demolition work required between Kochukhet and Banani
DOHS.

For this option, the total compensation is BDT 9,530 million. The breakdown is as follows:
1. Between Kochukhet and Banani DOHS
a. Land required: 15,000 m2
b. Building damage: few tin shed buildings
c. Passes through the residence of the Chief of Army Staff
d. Approximate cost: BDT 1,580 million
2. Within Banani DOHS
a. Land required: 5,000 m2
b. Building damage: 13 6-storey buildings and one mosque (entire one side of the road)
c. Approximate cost: BDT 7,950 million
Green Route
The green route passes through the golf course as well as Banani intersection, where there are some universities.

2. Banani Intersection
a. Land required: 3,000 m2
b. Building damage: 2 universities, 1 bank, 1 8-storey and 3 small buildings
c. Approximate cost: BDT 4,650 million

Blue Route
The blue route passes through the existing road but needs a lot of land acquisition.

a. Land required: 2,200 m2
b. Building damage: Two 6-storey government quarters
c. Approximate cost: BDT 270 million
4-21
(4) Comparison among Three Elevated Options within Cantonment Area
As explained in the earlier sections, the land acquisition and compensation costs for the three elevated alternatives
within the cantonment area are as follows:
Yellow route BDT 9,530 million = JPY 15.2 billion
Green route BDT 7,070 million = JPY 11.3 billion
Blue route BDT 6,545 million = JPY 10.5 billion
Although it seems that the Blue Route is the cheapest in terms of land and compensation, the construction cost
would be different as the length of the alternative routes are different. The comparison table is shown below:
Table 4-5 Cost Comparison Among Three Routes in the Cantonment
Yellow (Center) Green (North) Blue (South)
Land/ Compensation Cost BDT 9.5 billion BDT 7 billion BDT 6.5 billion
Length 1.2 km 1.35 km 2.0 km
Construction Cost BDT 1.3 billion BDT 1.6 billion BDT 2.3 billion
Total Cost BDT 11 billion BDT 8.7 billion BDT 8.9 billion
Source: METI Study Team
Thus, it can be said that the Green Route (north, through the golf course) is the cheapest among the three elevated
alternatives.
(5) Underground Option
In case of underground option, there will be no land requirement within the cantonment area. However, the
construction cost would be different. It may be noted here that land acquisition will still be required at the
technical intersection even for the underground option. As explained in Section 4.3.2, the estimated compensation
cost is BDT 5.6 billion. The comparison of civil construction cost and land/compensation cost for elevated and
underground is shown below. For underground option, the Yellow Route (underground) will be used, while for all
elevated portion the Green Route will be used.
Table 4-6 Cost Comparison Between All Elevated and Partial Underground
Item All Elevated Partial Underground
Viaduct BDT 17 billion BDT 8.9 billion
Tunnel 0 BDT 1.5 billion
Station BDT 11.2 billion BDT 20.7 billion
Land/Compensation (Technical Intersection) BDT 5.6 billion BDT 5.6 billion
4-22
Land/Compensation (Cantonment Area) BDT 7 billion 0
Total of Civil and Land Acquisition Only BDT 44.1 billion BDT 50.8 billion
Source: METI Study Team
Although the partial underground does not require land acquisition at the cantonment area, the combined cost
would be higher.
(6) Depot Area
As explained in the previous chapters, the land requirement for the depot is about 24 ha. Depot could be located
anywhere in the line. For MRT Line 5N, investigations were made at the end of the route, namely, at the end of
Gabtoli and end of Beraid. It was found that land availability at the Gabtoli end is rather limited and price is high.
Thus, it is proposed to establish the depot at the Beraid end, on the eastern side of Balu River
As shown in the following Figure 4-14, after about 1 km from Beraid Station towards east, there are empty lands
on both sides of the proposed alignment. There are enough areas to locate a 24 ha depot on either side. As the
northern side is now developed for future housing area, the depot is proposed on the southern side on mostly
uninhabited area.
Figure 4-14 Proposed Depot Area
It may be noted here that RAJUK is now preparing a future land use plan for 2016 to 2035, which is expected to
be released in early 2016. As shown in Figures 4-4 and 4-15, the proposed depot area at the east side of the Balu
River may be identified as conservation area, which would not be allowed for any development activities for the
4-23
next 20 years. The land use map is revised every 20 years by RAJUK taking into accont the land development
and natural environmental conservation needs. The land development needs should be properly assessed for the
finalization of land use plan for the next 20 years. Thus, it is recommended that DTCA/DMTC shall submit
application for the land development at the east bank of Balu River as Depot Area of MRT Line 5N for the
concerned agencies to assess the needs of land development and conservation. It is also required that the further
detailed investigation for the depot area should be conducted in technical, environmental and social viewpoints in
the next detailed feasibility study stage.
From the land availability aspect, it can be said that land for depot area (around 24 ha) is possible to secure at
anywhere between the Beraid and the proposed Vatara station at any side of the road. Although the initial
investment cost and operation cost might be less for a depot location close to Vatara station, a depot location just
by the bank of the Balu river can initiate “Transit oriented development” in these currently sparsely populated area.
At this stage of the Study, it is not possible to finalize the exact depot location in the absence of topo survey and
basic geotechnical investigation. For the purpose of this Study, depot location is propsed as mentioned above. It is
expected that the depot location will be finalized at the full feasibility study stage with results of topo and geo
investigation.

(7) Supplementary Study on the Southern Route of MRT Line 5 (Line 5S)
It was explained in the earlier chapters that RSTP proposed MRT Line 5 to have two loops, a part of the northern
loop has been considered as priority project and subject to this METI Study. However, as future reference, this
Study investigated the land acquisition requirement for the southern loop also. The southern loop runs from
Gabtoli to Aftab Nagar as shown in the following Figure 4-16.

Near the Panthapath Dhanmondi Intersection: When the line turns from the Mirpur Road (Dhanmondi) to
Panthapath, land acquisition is required at that intersection. The expected land requirement is about 1,500 m2 and
will require the removal of New Model School and College. Approximate cost is about BDT 350 million.

Entrance of Aftab Nagar: When the alignment enters into Aftab Nagar from the Hatirjheel area, land will be
required, where currently a DWASA building is located. The expected land requirement is about 15,000 m2 and
will require removal of the DWASA building. Approximate cost is BDT 1,590 million.

Therefore, the land acquisition-related cost compensation for the southern loop of MRT Line 5 is about BDT
1,940 million. In case a depot of about 30 ha is considered at the Aftab Nagar end, the depot land cost can be
about BDT 18,200 million. The possible depot location is shown in the following Figure 4-19.

4.4 Outline of Related Laws and Regulations on Environmental and
Social Considerations
4.4.1 Environmental Impact Assessment (EIA)
The Bangladesh National Environmental Policy, approved in May 1992, sets out the basic framework for
environmental protection together with a set of broad sector guidelines. The policy states that an Environmental
Impact Assessment (EIA) should be conducted before any large-scale transport development project is
undertaken.
The Environmental Conservation Act (ECA), 1995 (and its subsequent amendments in 2000 and 2002) sets the
establishment of the Department of Environment (DOE), among others. This Act also empowered DOE to do the
4-26
following:
Declaration of Ecologically Critical Areas
Requirement of obtaining Environmental Clearance Certificate (ECC) for any project.
Regulation with respect to vehicles emitting harmful smoke into the environment.
Promulgation of standards for air, water, and noise quality for different land uses and purposes.
Promulgation of acceptable limits for discharging and emitting wastewater.
Environment Conservation Rules, 1997 (and its subsequent amendments in 2002 and 2003) are the first set of
rules promulgated under the ECA 1995, which provides the following:
National Environmental Quality Standards (EQS) for ambient air; surface water and groundwater; drinking
water; industrial effluents; and air, noise and vehicular exhaust emissions;
Categorization of industries, development projects, and other activities on the basis of anticipated
environmental impact;
Procedure for obtaining and renewing an environmental clearance over the construction phase, and
obtaining an environmental clearance for operation of the project;
Requirement for undertaking Initial Environmental Examination (IEE) and EIA in keeping with the
category of the proposed activity (including guidelines of EIA preparation); and
Procedure for claiming damage by persons affected by polluting activities or actions that adversely affect
the conduct of ordinary civic life.
Among many other environmental-related regulations, the Sound Pollution (Control) Rules, 2006 are relevant to
this Project, which set the values of noise limit.
The DOE, an agency under the Ministry of Environment and Forest (MOEF), is the regulatory body and the
enforcement agency of all environmental-related activities. Like all other projects, this Project also needs to meet
the requirements of the DOE. An EIA study needs to be undertaken for obtaining the environmental clearance. As
per ECR 1997, this Project will be considered as ‘Red Category’ as it falls under
“construction/reconstruction/extension of bridges over 100 m in length”. The steps to be followed for obtaining
the ECC for Red Category from DOE are outlined in Figure 4-20. Public participation or consultation is not a
condition in the ECR 1997 and/or EIA Guidelines; however, DOE prefers the proponent to engage in public
participation and put conditions while providing site clearance or during the approval of the terms of reference
(TOR) of the EIA.

4.4.2 Land Acquisition Plan (LAP) and Resettlement Action Plan (RAP)
The current legislation governing land acquisition in Bangladesh is the “Acquisition and Requisition of
Immovable Property Ordinance” 1982 (hereinafter referred to as “the Ordinance”) and subsequent amendments
(1989, 1993, 1994 and 2004). The Ordinance provides certain safeguards for landowners and has provisions for
payment of ‘fair value’ for the property acquired. The 1994 amendment also made provision for payment of crop
compensation to tenant cultivators. However, it does not cover project-affected persons (PAPs) without title or
ownership record such as informal settler/squatters, occupiers, and informal tenants and lease-holders (without
document) and does not ensure replacement value of the property acquired. It does not permit the affected persons
to take the salvageable materials for which compensation has been paid. It has no provision for resettlement
assistance and transitional allowances for restoration of livelihoods of the non-titled affected persons.
According to the Ordinance, the Ministry of Land (MOL) is authorized to deal with land acquisition; however, in
practice, MOL deals with the issue through the concerned Deputy Commissioner (DC), who is the head of the
district administration. The DC processes land acquisition under the Ordinance and pays compensation to the legal
owners of the acquired land.

Under this Ordinance, the executing agency needs to prepare the land schedule required to be accrued, and places
the acquisition request to concern DC. Following the Ordinance, the DC determines the: (i) market value of
acquired assets on the date of notice of acquisition (based on the registered value of similar property bought
and/or sold in the area over the preceding 12 months); and (ii) 50% premium on the assessed value (other than
crops) due to compulsory acquisition. The DC payment awarded to owners is called ‘cash compensation under
law’ (CCL). The value paid as CCL is invariably less than the “market value” as owners customarily report
undervalued land transaction prices in order to pay a lower stamp duty and registration fee. As a result,
compensation for land paid by DC, including premiums, remains less than the real market price or replacement
value (RV).
The landowner has to establish ownership by producing a record-of-rights (RoR) in order to be eligible for
compensation under the law. ROR records prepared under Section 143 or 144 of the State Acquisition and
Tenancy Act 1950 (revised 1994) are not always updated and as a result, legal landowners have faced difficulties
trying to “prove” ownership. The PAPs must also produce a rent receipt or receipt of land development tax.
It is usually recommended that khas (i.e., government owned) lands should be acquired first in preference to
private land. If a project acquires only khas, the land will be transferred through an inter-ministerial meeting
following the preparation of an acquisition proposal submitted to DC/MOL. Places of worship, graveyards, and
cremation grounds are discouraged to be acquired.
As explained above, the DC payments as CCL are, in most cases, less than the RV as defined by the Asian
Development Bank or the World Bank. As a result, it is customary in Bangladesh for all official development
assistance (ODA) projects that “additional” payments are made to PAPs following World Bank’s OP 4.12 or its
equivalent. Some of the important elements of such practice are listed below:
Compensation must be based on the full replacement cost as much as possible.
Compensation and other kinds of assistance must be provided prior to displacement.
Resettlement action plans (RAPs) must be prepared and made available to the public.
In preparing a RAP, consultations must be held with the affected people.
Appropriate and accessible grievance mechanisms must be established for the affected people and their
communities.
Eligibility of benefits not only include the PAPs who have formal legal rights to land, but also the PAPs who
do not have formal legal rights to land at the time of census, but have a claim to such land or assets, and
even the PAPs who have no recognizable legal right to the land they are occupying.
4.4.3 JICA Guidelines on Environmental and Social Considerations
Financing of this Project is not finalized yet. However, there is an indication that the Bangladesh side might ask
for Japanese assistance, first in the form of technical assistance to carry out the feasibility study, and then in the
form of yen loan for the implementation.
In case the Bangladesh side applies for Japanese assistance and Japanese side agrees to support, this Project will
be under the JICA’s Guidelines for Environmental and Social Considerations of 2010. As explained in the
4-29
previous sections, the legal framework of Bangladesh will comply with the JICA guidelines.
According to the JICA guidelines, the Project will come under category A and will require full EIA, Bangladesh
regulation also calls for full EIA for this kind of project. Similarly, for social issues like resettlement and
compensation, the JICA guidelines follow the World Bank OP 4.12. Although the Bangladesh legal framework
does not comply with World Bank OP 4.12, all ODA projects in Bangladesh including JICA-financed projects are
required to follow the donor agency’s requirements. Thus, it is obvious that the Project proponent will follow the
JICA guidelines for land acquisition and resettlement compensation issues.
4.5 Measures to be Taken by Host Country to Implement the Project
During the full feasibility study, the Project proponent must prepare the EIA and RAP documents. The EIA
document should be submitted to DOE to get ECC. Also, the RAP has to be approved by the competent authority.
These steps are required for loan processing from development partners (like JICA).
During the detailed design stage, the EIA and the RAP document should be updated following the Project details
confirmed at that stage. These updated EIA and RAP documents again have to be approved.
Based on the approved EIA, the Environmental Construction Specification (ECS) should be prepared and
included in the main contractors bidding document, so that all environmental management measures can be
implemented by the contractor. For the RAP implementation, the Proponent must engage an implementing
non-governmental organization (NGO) to carry out the activities as prescribed by the RAP document.
Safeguard-related activities and their expected execution time frame are shown in Table 4-7 below.

5.1 Cost Estimates
5.1.1 Construction Plan
(1) Elevated Viaduct
During site investigation, the width of the road where the MRT East-West Line is planned on is recognized to be
comparatively narrow for construction. For example, it is only 21 m wide at locations of bridges between lakes
(Chainage: 9k400 m to 9k450 m and 10k320 m to 10k460 m) as shown in Figure 5-1. Actually, the bridge is
composed of three consecutive box culverts as a channel, approximately 20 m long and 15 m wide. Once the
construction starts, only one lane each way will be maintained in spite of heavy traffic due to civil construction
works such as piling, foundation, pier, and viaduct.
Fortunately, during this Study through discussions with DTCA, shield tunnel method under the cantonment area is
preferably adopted, and this will extend to this section solving the narrow road issue above.
Figure 5-1 Example for Traffic Conditions at Narrow Road
Source: METI Study Team
As another example, at the end of the eastern side connecting to the planned depot, which is not a developed area,
only one lane each way is paved with pre-stressed concrete bridge. In that case, track centerline shall be
coordinated with the future road development plan and additional land acquisition for connections with the depot
access lines shall be required.

The footing of the pier is composed of four pieces of bored piles, reinforced concrete, and temporary retaining
walls instead of one pile for one pier according to the study of the MRT Line 6. The pier and the pier top would be
made of in-situ cast concrete or pre-cast concrete. A viaduct will be erected by temporary launching girders, which
hang up pre-cast concrete blocks from the ground to the designed position and combine them into a bridge with
post tension pre-stressed system. This launching method will be able to shorten the construction period and the
influence on the road traffic. This construction method will be referred to the study of MRT Line 6. Working area
for construction on the road requires a minimum width of 10 m at the middle of the road for the above foundation
and viaduct works.
The design and construction methods for stations on the ground shall be finalized at the feasibility study, basic
design, and detailed design stages, while their locations, environmental conditions of surrounding areas,
connections to other metro lines, and road traffic control methods will be thoroughly researched.
(2) Shield Tunnel and Underground Station
The plan for the underground tunnel through the cantonment area has advantage of not demolishing residential
buildings. The tunnel shall be set vertically lower than one outside diameter (O.D.) of the shield tunnel machine
from the tip of the pile foundation of the building, which is said to be 18 m long; therefore, the rail level will be 34
m below the ground. This will inflate the construction cost due to the length of the tunnel and depth of the station.
The transition connecting to the elevated structure from the tunnel, which is made of box culverts and U-shaped
retaining walls, shall occupy the road permanently, which will largely affect the road traffic situation.
At present, the Study Team does not have enough preparation and time to investigate the details for tunnel and
underground station so that the construction plan is envisioned with typical model as follows:
a) Vertical shafts for departure and exit of shield machines.
b) Shield tunnel O.D. = 7.0 m for single line, up and down, two lanes.
c) Underground station which will be built by top-down method with diaphragm walls.
d) Transition from tunnel to viaduct, composed of box culvert and U-shaped wall.
e) Ventilation shaft, if necessary, evacuation system, and flood prevention facilities.
The construction of underground station will start from diaphragm walls which are excavated with slurry and
replaced by high-grade concrete together with fabricated reinforcement steel bars. Each shape of the excavation of
diaphragm wall is like a long rectangular pile and each element shall be connected vertically with special
technique to serve as continuous wall against water seepage. It will work as retaining wall and structural outer
wall permanently. For this work, the road will be divided by two lots longitudinally, one for construction, and the
other for traffic unless the road is so wide that whole construction area can be prepared within the road. Once one
side of the diaphragm wall is completed, the construction and traffic lots will be switched. Diversion, remaking
sidewalk as traffic pavement, and temporary steel decking system would be adopted to maintain the traffic, if
5-3
necessary. After the completion of the diaphragm walls, the excavation and slab concrete works will be executed
from top (near the ground) to the bottom, i.e., top-down method. Each slab concrete acts as strut which support the
diaphragm walls against earth pressure due to excavation. In case the distance between concrete slabs is wide,
temporary struts will be required. Equipment for these works will be installed on the road by making limited
working zone to maintain the traffic. After casting the bottom slab concrete, the shield machines will pass on it,
followed by the platform concrete, installation of elevators and escalators, and architectural finishing works. Road
will be reinstated after completion of the station structures with entrances.
The location of vertical shaft (departure) is critical for tunnel works. It is built on the line of track and situated at
an open space to assemble shield machines, supply materials (e.g., segment which is made of concrete or steel and
installed as circular outer structure combining several blocks in-situ), replenish consumables, and haul out
excavated soil from the tunnel. It shall be connected with the logistics yards for the storage of segments and
excavated soil to be stabilized, so that the location of vertical shaft and the size of supplemental yards will heavily
affect the road traffic and progress of the tunnel. The vertical shaft itself is inherently a temporary facility but it
would remain as ventilation shaft or evacuation stairs occasionally.
Utilities shall be away from the area of underground stations and transitions before construction.
Smoke dispersion, ventilation, evacuation facilities, and flood measures shall be prepared in the tunnel.
5.1.2 Construction Cost
The cost of viaducts is estimated by quantity, which is calculated by schematic drawings considering the tentative
span of piers to be 25 m, and unit rate, which follows the estimation standards in Japan but adjusted to local
conditions. The costs for shield tunnel, underground station, electrical and mechanical (E&M) systems, and
rolling stocks are referred to those of similar previous projects. Construction cost is composed of three parts, i.e.:
civil works, procurement of equipment, and consulting services. The Project cost includes the construction cost,
which is composed of escalation cost, contingency, land acquisition, value-added tax (VAT), import tax,
administration cost, etc., as shown in Table 5-1. The cost is presented in Bangladesh Taka (BDT, local currency) as
requested by DTCA.
Exchange rate is BDT 1.0 = JPY 1.628, USD 1.0= JPY 123.96 as of June 2015.
Total Project cost becomes BDT 218 billion as shown in Table 5-1.

5.2 Results of the Preliminary Analysis of the Economic and Financial Viability
5.2.1 Preconditions of the Analysis
(1) Evaluation Period
The evaluation period of 40 years is applied to the economic and financial analyses of the Project. It is assumed
that the construction of the Project (including engineering services) would start in 2018 and end in 2026, and the
commercial operation would start in July 2027 after the commissioning for half year.
(2) Asset Lives
The asset lives of the civil structure, rolling stock, and other investment materials in the Project are assumed as
follows:
- Civil structure (50 years from the beginning of operation)
- Rolling stock (25 years from the beginning of operation)
- E&M equipment including control system, telecommunications and signaling, power distribution, and automatic
fare collection (AFC) (20 years from the beginning of operation)
The residual values at the end of the evaluation period are calculated based on the asset lives, and the
reinvestments would take place according to the asset lives during the evaluation period.
(3) Discount Rate
The discount rate is used for the calculation of the net present value (NPV) and the benefit to cost ratio (B/C). The
value differs between the economic and financial analyses. In the economic analysis, the Study employed a
discount rate of 16%, which is suggested by DCTA as the general opportunity cost in Bangladesh, although
commonly used value for economic analysis is approximately 10-12% in developing countries.
On the other hand, the long-term real interest rate is generally used in financial analysis. In the Study, the discount
rate for the financial analysis is calculated at 7.1% from the long-term lending rate of 12% in Bangladesh and the
price escalation of 4.9% that is assumed in the Study.
(4) Currency and Base Year
All prices are valued in the domestic price numerate (taka) at 2015 constant prices. The yen portion of the Project
cost estimates are converted into taka at an exchange rate of BDT 1 = JPY 1.628. The Shadow Exchange Rate
Factor (SERF), which is used to convert financial costs in foreign currency to economic costs, is assumed as 1.0.
The income tax rate is approximately 15%. Since the personnel cost accounts for a large part of E/S and
administration cost, a conversion rate of 0.85 is used for these costs in domestic currency, while 0.9 is used for the
5-6
other costs.
(5) Yearly Conversion
The results of the demand forecast and the operation plan represent daily values. The yearly values are calculated
by using 330 days per year considering the holidays.
5.2.2 Initial Investment Cost
The initial investment cost in the financial analysis is estimated at BDT 155.4 billion from the result of the cost
estimates by excluding the price escalation and the interest during construction. The initial investment cost in
economic prices is estimated from the financial cost by excluding VAT, import tax, and the income tax of the
personnel cost. Since the income tax of the personnel cost cannot be directly calculated, it is estimated by
multiplying conversion factors to the domestic currency portion. The economic cost is estimated at BDT 130.8
billion.

5.2.3 Operation and Maintenance (O&M) Cost
(1) Estimation Method
The O&M cost is estimated by applying the unit costs to the corresponding O&M items consisting of track, E&M,
rolling stock, station, operation, and traction power. Each O&M cost, except for traction power, is decomposed
into personnel cost and material cost.
(2) Personnel Cost
The number of staff required for O&M is estimated by applying ratios of the number of staff to explanatory
variables such as train-km, number of stations, route length, and number of cars by each O&M activity. The ratios

(4) Traction Power Cost
It is assumed that the energy consumption for traction of trains is 1.93 kWh per car-km (Refer to Chapter 3). The
unit cost of the electricity consumption is assumed to be BDT 7.2 per kWh, based on the tariff table (Category-H,
Flat Rate) of the Dhaka Electric Supply Company Limited (DESCO).
(5) Results of O&M Estimates
Table 5-6 below shows the results of the estimation of O&M cost of the Project (16.8 km). The O&M cost in 2030
is estimated at BDT 912 million. The result is close to the estimated O&M cost of JPY 1,238 million (BDT 760
5-9
million) of MRT Line 6 Stages 1 and 2 (15.4 km).

(6) Additional Investment
According to the transport plan, it will be necessary to purchase 3-4 train sets every five years after 2035.
Although a train set is composed of six cars, it is assumed that 3-5 cars will be procured every year in the
investment plan.
5.2.4 Revenue Projection
(1) Present Fare Level of Public Transport in Dhaka
The fare of existing buses in Dhaka is approximately BDT 1.5-1.6/km, while that of CNGs, which are popular
three-wheel auto cars, is BDT 30 for the first 2 km.
(2) Fare Setting in the Demand Forecast
In the demand forecast carried out by the JICA RSTP Team, the fare of the MRT network was assumed to be BDT
16 as the minimum charge plus BDT 2/km, with the condition that transfer to other lines is free of charge.
(3) Assumption of the Fare Structure
The fare setting used in the RSTP is used because the result of the demand forecast in the PSTP (interim stage) is
used for the demand forecast. The demand forecast in the RSTP includes transfer passengers between MRT
East-West Line and other lines, and MRT East-West Line cannot necessarily take all the minimum charges which

are paid by the transfer passengers. It is assumed that transfer passengers account for 20% of the total passengers,
and MRT East-West Line takes 50% of the minimum charge paid by the transfer passengers as revenue.
(4) Non-rail Business
Non-rail business, such as property development around stations, rental of the station space, and advertisement, is
one of the revenue sources in railway projects. In this study, the investment on non-rail business is not considered,
but the revenue from advertisement and space rental is included in the total revenue considering that the amount
of revenue is very small. It is assumed that the revenue from the non-rail business accounts for 5% of the
passenger fare revenue.
(5) Revenue Projection
The result of the revenue projection is shown in Table 5-8 below. Since the commercial operation in the first year
(2027) is half of the year, the revenue is estimated as half of the yearly projection.

5.2.5 Financial Cash Flow Analysis
(1) Financial Cash Flow
The financial cash flow is calculated using the constant prices, which is applied in the project appraisals by
international organizations in general. In this case, the internal rate of return is compared with the real interest rate.
Table 5-9 below shows the financial cash flow. The reinvestment of E&M is scheduled 20 years after the
commencement of operation. Additional investments will be necessary for rolling stock according to the increase
in demand, while the reinvestment of rolling stock is scheduled 25 years after the commencement the operation.
The financial internal rate of return (FIRR) is calculated at 2.7%. FIRR is same as the return of the Project when
all the investment cost is prepared as equity. Since the FIRR is lower than the real interest rate of 7.1% in
Bangladesh, the profitability of the Project is low; therefore, implementation by the private sector would be
difficult.

(2) Applicability of Public-Private Partnership (PPP) Scheme
PPP projects can be categorized into two large groups, namely, financially free-standing projects by the private
sector such as BOT and projects in which the public sector purchases the services provided by the private sector.
Since the Project is not commercially viable as shown in the results of the FIRR calculation and not possible as a
financially independent project, it is difficult to apply the BOT scheme.
In case that the Project should be implemented by the private sector as a financially independent project,
additional business other than railway such as urban development along the railway line that can produce profit is
necessary. However, the implementation by this approach will be difficult due to the lack of land for real estate
development because the alignment of MRT East-West Line passes through developed areas. This is also
unrealistic because it is necessary to wait for the proposal of the private sector which engages in real estate
development along MRT East-West Line.
Vertical separation, which means separating the railway business into the infrastructure by public and the
operation by private based on the concept that the infrastructure of the railway is a part of public assets like roads,
is one of the measures to make the railway project commercially viable. To evaluate the vertical separation, FIRR
is calculated for the case when the private sector makes investment on E&M and rolling stock, which are
categorized in the cost estimates, and run the business by taking the responsibility of O&M. The FIRR of the
above case is calculated at 8%, which is higher than the assumed real interest rate of 7.1%, and the project will be
commercially viable. However, if the Project is implemented by the private sector, the return of the Project is
required to be higher than the interest rate of banks considering the risk premium for the Project.
In case that the private sector constructs and operates MRT Line 6 with the payment by the public sector for the
services provided by the private sector, the public sector will pay the private sector for the initial investment cost
in installments in the future. Since the profit of the private sector is added to the payment, the total amount of
payment by the public sector will be larger than the repayment of principal and interests in the case of using a soft
loan.

Currently, the fare system of the mass transit network in Dhaka has not been concluded yet. In view of users’
benefit, the integrated fare system that does not require additional charge for the transfer of lines is desirable,
although it is necessary to establish a mechanism to distribute the passenger revenue to each operator in case of
BOT scheme.
5.2.6 Economic Benefits
(1) Method
For the economic analysis of the Project, the total transport cost approach, which calculates the reduction in the
total transport cost between “With Case” and “Without Case”, shall be adopted. The economic benefit of the
Project consists of (a) reduction of travel time of passengers who shifted their transport mode from buses to the
metro; and (b) reduction of vehicle operating costs of buses due to the reduction in vehicle kilometers of buses.
(2) Value of Time
The value of time, which is used to calculate the time saving benefit, is estimated from the average hourly income,
which is estimated from the average monthly salary and the average working hours in Dhaka.
The average monthly salary in the urban area of Bangladesh was BDT 16,477 in 2010, according to the
Household Income and Expenditure Survey 2010 by the Bangladesh Bureau of Statistics (BBS). To estimate the
average monthly income in 2015 from this data, it is assumed that the income level has increased at the same ratio
of the GDP per capita. According to the World Bank database, the per capita GDP in 2015 is 1.27 times that of
2010 at 2005 constant prices. The average monthly working hours is assumed to be 170 hours. The value of time
of car users is estimated by adjusting that of bus passengers using the value of time by income class in 2015,
which is estimated in the JICA study (October 2011).

(3) Reduction in Travel Time
The travel time reduction is estimated by comparing the travel time by metro with that by road in “Without Case”
which runs in parallel with the metro.
Benefit of Travel Time Reduction
= (passenger-hours in “Without Case” – passenger-hours in “With Case”) * value of time (BDT/hour/person)
The average speed of buses is assumed to be 8.65 km/hour based on the RSTP, while that of the MRT East-West
Line is 33 km/h according to the operation plan. The average travel speed of a private car is assumed as 16 km/h.
The route runs through the cantonment area, where a parallel road does not exist. It is assumed that passengers
travelling on the route would make a detour with the length of 4.2 km.
Although the traffic congestion along MRT East-West Line will be relieved because of the reduction in the
number of bus and private cars, the present available data is not enough to analyze this impact. In this Study, the
benefit of the decongestion is estimated by assuming that the travel time will be reduced by eight minutes per
person for 50,000 car users per day along MRT East-West Line, considering the present traffic situation.
Table 5-12 below shows the results of the benefit of the travel time reduction.

(4) Reduction in Vehicle Operating Cost (VOC)
The Project will reduce the frequency of bus services because of the shift of transit passengers from buses to the
metro, which can reduce the VOC of buses. The reduction in VOC is calculated according to the following

VOC = UC * (PKM/OR)
Where:
UC: VOC of buses per vehicle-kilometer (BDT/vehicle-km)
PKM: Passenger-kilometer of the metro per year
OR: Average occupancy rate of buses
The occupancy rate of buses fluctuates daily, showing high occupancy rates in peak hours and low rates in
off-peak hours. In this Study, it is assumed that the passenger occupancy rate of a bus is 40 passengers on average.
The VOCs per vehicle-km of buses in Bangladesh are estimated in several reports. The Road User Cost Study
(2009) estimated the financial and economic VOC of buses by type, in which the VOCs of minibuses, which is the
most common bus type along the route, are estimated at BDT 31.35/km for financial VOC and BDT 28.21/km for
economic VOC.

5.2.7 Economic Indicators
(1) Benefit and Cost Flow
Table 5-14 below shows the flow of economic cost and benefit of the Project. The economic internal rate of return
(EIRR) was calculated as 16.2%. Since this is higher than the opportunity cost of capital in Bangladesh, the
Project is economically feasible. On the other hand, B/C is as small as 1.02, and the net present value (NPV) is as
small as approximately BDT 0.75 billion compared with the investment cost. In case that the discount rate of 12%
is used, B/C is calculated at 1.5 and NPV is calculated at BDT 32.8 billion.

means that the EIRR is 16% or more, while the red color means that the EIRR is less than 16%. In case of 10%
increase in the economic cost, or 10% decrease in the economic benefit, the EIRR will be smaller than 16%,
which is suggested by DCTA. Even in the case that the economic benefit is smaller than 20% and the economic
cost is larger than 20%, the EIRR is still larger than 12%, which is commonly used for appraisal by international
banks including the Asian Development Bank (ADB).

(3) Conclusion
The results of the financial analysis show that the return on investment of the Project is so low that its
implementation by the private sector will be difficult. On the other hand, the Project can be established by using
loans with low interest rates such as Japanese Yen Loan, because its FIRR is calculated as positive.
In the economic analysis, EIRR exceeds 16%, which is given by the counterpart as the opportunity cost in
Bangladesh. This means that the Project is economically feasible.

Chapter6 Planned Project Implementation Schedule
6-1
6.1 Implementation Schedule
6.1.1 Construction Method
It is important for the Project to reasonably forecast the construction schedule. Construction is composed of civil
works, track works, electrical and mechanical (E&M) system works, and test and commissioning. Construction of
the depot shall be provided earlier than the track works, and testing and training of rolling stocks. In case of
elevated viaduct, the whole line will be divided to several construction blocks to manage traffic, quality, safety,
cost, and schedule. Generally, the more the number of these divisions are, the shorter the construction time is, but
the more cost there is. In other words, this type of construction, i.e., long distance of structure on the ground, is
easily adjustable in terms of schedule and cost as variations. Not only the civil works but also subsequent works
such as track and E&M system works can be managed within the schedule by appropriate measures.
In case of the shield tunnel, the critical path of the schedule is simple and not flexible to changing situation, which
consists of the design and manufacture of the shield machine, construction of underground station where the
shield machine will pass on the bottom slab concrete, completion of the tunnel, track works in the tunnel, and
E&M system works in the tunnel. Therefore, once troubles come up such as delay of underground station due to
land acquisition or utilities diversion, the excavation of tunnel due to the mismatch of the machine with the
geotechnical conditions or abnormal ground conditions, it would be difficult to make up the schedule. It is of great
importance to investigate the soil conditions and the design including construction sequence for tunnels and
underground stations prior to the construction.
The sequence of constructing piers of viaduct structure is bored piles, driving steel sheet piles, excavation, base
concrete, pier concrete, backfilling, removing steel sheet piles, and pier top concrete, which would take two
months. A block is 200 m in length, and the construction will proceed block by block together with traffic control.
At the same time, precast concrete blocks for the viaduct will start to be produced and stored at the fabrication
yard. Temporary launching girders will be set on piers and bridges will be constructed span by span using the
pre-stressed method. Four pieces of launching girders will be provided for the 11.3 km length of viaduct so that
construction period is expected to take four years.
In case of tunnel construction, these activities will start simultaneously with the design and fabrication of shield
machines and construction of vertical shaft and underground stations, which is foreseen to take two years because
of the depth. The excavation speed of shield machine is expected to be 200 m to 300 m per month except in the
initial stages. A shield machine per single line is provided for a length of 5.2 km; therefore, the whole construction
period will take five years as shown in Table 6-1. Subsequent works such as track, cable, communication, and
ventilation can only commence after the shield machine is demolished from the tunnel. If the number of shield
machines is set to four, the construction period will be dramatically shortened. This analysis will be done in the
next study.

6.2 Issues on Project Implementation
Remarkable construction activities, which would affect the cost and implementation of the Project, are seen during
the site visit. One is the reclamation with pumps around the planned depot area and the other is a great number of
building constructions at the central part of Dhaka City. In addition to these construction activities, MRT, BRT,
and flyover projects are going to be developed and land readjustment plan will be enforced in the near future.
From the point of view of recent economical growth in Dhaka, the construction cost would be swollen more than
expected and land acquisition would be critical for proceeding with this Project. It is desirable to establish the
cooperation between the public and private parties in obtaining the land for public works like MRT project. For
example, the entrance from both elevated and underground stations will generally be located on the sidewalk in
case of enough width of the road, while it would be a positive idea to combine the public structure (entrance) and
private equity (e.g., shopping mall, condominiums) in case of narrow road. The location of the entrance of the
underground station, which is composed of staircases, escalators, and elevators, is of great importance. It will be
an advantage for the passengers to ride the MRT smoothly and to develop the business environment surrounding
the stations.
In case of tunnel, the design of tunnel as well as underground stations shall be taken into consideration in the
6-4
construction method more thoroughly than that for elevated structure; otherwise, unexpected troubles would
happen often during construction.
Where tunnel passes under residential buildings, psychological and environmental issues may occur during the
construction stage or permanently. It is of great importance to spread information widely before construction.
Integrated engineering technology about tunnel construction experienced in Japan shall be available. This is a
great opportunity to introduce tunnel technique to the MRT East-West Line Project in Dhaka.

Chapter7 Project Implementing Agencies
7-1
7.1 Overview of the Implementing Agencies of the Host Country
For any metro rail-related projects in Dhaka, two agencies are directly concerned, namely, Dhaka Transport
Coordination Authority (DTCA) and Dhaka Mass Transit Company Ltd. (DMTC). DTCA, as the coordinating
authority of all transportation system in Dhaka, is also mandated to conduct planning like feasibility studies.
DMTC, on the other hand, is a state-owned company (SOC) responsible to implement any metro rail project in
Dhaka. However, if the project is implemented through public-private partnership (PPP), implementation
mechanism can be different and will depend on the extent of engagement of the private sector. For example, in
case of build-operate-transfer (BOT), a special purpose organization (SPO) might be formed. However, if the PPP
engagement is in the form of concession only, it is still possible that DMTC will be the implementing agency. In
this chapter, assessment will be made for DMTC only.
As mentioned above, DMTC is an SOC and is governed according to its own regulations. Legally, all SOCs are
autonomous bodies but the respective ministries appoint their board of directors. Effectively, the SOCs reflect
their line ministry positions. However, as the SOC’s board can take all decisions, the paper work involving the
ministry can be reduced and thus many processes can be expedited. DMTC, like all SOCs, is legally separated
from the government but heavily depends on the financial issuances of the government like loans and subsidies.
7.2 Organization for the Implementing Agencies of the Host Country
The DMTC is an SOC mandated to implement and operate all metro rails on behalf of the government. Its
formation dates back to the 2010 JICA Dhaka Urban Transportation Study (DHUTS), which proposed to form an
authority for the implementation of MRT Line 6 and later for any other lines. Later, the Study for Institutional
Strengthening and Capacity Enhancement of Transport Related Agencies in Dhaka City (SISCETRA) was
undertaken by DTCB (currently DTCA) engaging local consultants. The study recommended the formation of an
authority which is essentially in line with the proposal of DHUTS and proposed the name “Dhaka Mass Transit
Company”. They also suggested that DMTC can be developed in stages and in the beginning it should be formed
with just 18 officials.
During the implementation of MRT Line 6, an institutional development consultant (IDC) was engaged, who will
formulate the full expansion of DMTC. IDC is expected to complete his/her work by 2015 and his/her scope
includes organogram, job description, business plan, financial plan, and work procedure, among others.
DMTC was formed in line with the Metro Rail Act of 2015 and complying with the Companies Act of 1994. The
registration date of DMTC was June 3, 2013 and the registration number is C-109 490/13. The mandate
mentioned in its Memorandum and Articles of Association is as follows (Sec III A 1):
To establish, operate, and maintain including planning, designing, development, construction, and financing
of MRT system in and around Dhaka City (as defined and specified in the Dhaka Transport Coordination Act,
2012 (Act No. 8 of 2012)) so as to meet the urban transport needs of Dhaka and its neighbouring areas. MRT
7-2
system covers metro railway, light railway, mono rail, sky bus, or any similar people mover system operating
on a dedicated guide way at surface, above or below the ground level.
In Sec III A 5b, DMTC is also mandated to carry out feasibility study of the system; thus, the feasibility study of
the MRT Line 5e can be undertaken by DMTC.
The authorized share capital of the company is BDT 10,000,000,000,000 (10,000 cr), which is approximately
equivalent to USD 800 million. There are eight shareholders of DMTC and their share numbers are shown in Table
7-1 below.

At present, DMTC is still in the early stages of formation. Currently, one managing director, one deputy managing
director, two directors, two chief engineers, and few deputy general managers are mobilized from different
government agencies. The IDC is supposed to submit its report by end of 2015 outlining the organogram,
manpower, job description, accounting system, and recruitment plan. It is expected that recruitment will start from
2016. In addition, IDC will also prepare a detailed training program for management and financial positions.

On the other hand, the General Consultant (GC) of MRT Line 6 will prepare the operation and maintenance
(O&M)-related manpower requirement, recruitment plan, and training schedule. It may be mentioned that this will
be prepared mainly focusing on the operation of MRT Line 6 only. For additional lines, such arrangement has to
be updated.
7.3 Current Activities of Project Implementing Agency
DMTC is formed to implement and operate the urban metro rail system. However, this is a new system and there
is no readily available in-country skilled manpower. It is naturally anticipated that DMTC will face difficulties in
recruiting qualified personnel.
DMTC started with very few staff. The MRT Line 6 implementation was planned in a very effective way so that
the GC can nourish the DMTC in its infancy. GC will prepare the total organizational setup related to O&M. GC
will then help in recruitment and provide training. On the other hand, IDC will prepare the management and
financial organization of DMTC.
Although it is expected that DMTC will get significant exposure through the implementation of MRT Line 6, it
cannot be expected that with the implementation of just one line, DMTC can handle all the complex and
interrelated technical, contractual, accounting, and management aspects of a metro rail implementation. Further,
the underground construction associated with MRT Line 5 will present a whole new set of issues. Thus, it is
recommended that at least for the next line also, a GC should be appointed to take the role of an “Engineer”,
rather than to employ the fragmented services of a design and procurement consultant (DPC), a construction
supervision consultant (CSC), and a management support consultant (MSC). By having a GC, DMTC can get
on-the-job training very effectively. In addition, periodic training must be provided to DMTC officials for their
capacity development.
Chapter8 Technical Advantages of Japanese Companies
8-1
8.1 International Competitiveness of Japanese Companies for the Project Implementation
Construction technology in urban railway in Japan is known as high level technology in the world, including
bridge construction technology in narrow construction space, tunnel construction, rolling stock, depot equipment,
signaling, power, telecommunication, train operation control system, and station equipment. Japanese companies
have various experiences in overseas projects, and they have been highly appreciated in the view of quality,
schedule, safety and overall project management.
MRT Line 6, with a total length of 20 km and which has been selected as the top priority line under the Dhaka
Urban Transportation Study (DHUTS), is currently in progress as one of the projects financed under official
development assistance (ODA) loans. Dhaka Mass Transit Company (DMTC), owner of the MRT Line 6 Project,
expects Japanese companies to participate in the various construction packages (construction, rolling stock, and
railway system) in this Project.
In addition, there is a possibility of utilizing Japanese technology and knowhow such as management,
maintenance, and staff education. Therefore, there is high possibility of orders for railway system and
maintenance from Japanese companies under this Project.
Advantages of railway technology of Japan in the international competition are mentioned below.
1) Safety, Stability
The number of MRT passengers in Japan is large in the world. Japanese railway is ultra-high density
transportation, however serious accident rate is very small, even in comparison with other countries.
2) Energy Saving
Stable mass transit, reduced weight rolling stock, and highly efficient regenerative braking are enabling to reduce
the energy consumption and carbon dioxide.
3) Construction Technology
Since railway structure is often constructed in narrow and congested site in Japanese urban area, construction
