EXECUTIVE SUMMARY

CHAPTER 1: INTRODUCTION

1.1 Project Description

The 6-laning of existing 4-laned national highway sections is to be executed through public,

private partnership (PPP) on built, operate and transfer basis following design and built-

finance-operate (DBFO) pattern. The 6-laning of projects has essentially been conceived as a

retrofitting job on existing 4-laned national highways causing minimum possible

inconvenience to the traffic. It is taken up as a separate phase viz. NHDP Phase-V by

National Highways Authority of India.

Etawah- Chakeri (Kanpur) 160.212 km long section of NH-2 in Uttar Pradesh State, which

falls on the Delhi - Kolkata arm of Golden Quadrilateral, has been included for 6- laning

under NHDP-V. M/s. Consulting Engineers Group Ltd., having their registered office at E-

12, Moji Colony, Malviya Nagar, Jaipur, were selected for preparation of Feasibility Report.

The order to commence consultancy services was issued by NHAI on 30th

December 2009.

As per clause 2.3 of the conditions of contract, read with Special Condition of contract, the

Consultants are required to commence their services at the end of 15 days of the letter of

January 2010 and an intimation to this effect has been communicated to NHAI vide

Consultant’s letter No. CEG/DL/87/2009/713 dated 15 January, 2010.

1.2 NHAI Overview

The NHAI was created through the promulgation of the National Highways Authority of

India Act, 1988. In February 1995, the Authority was formally made an autonomous body.

The vision of National Highways Authority of India is to meet the nation’s need for the

provision and maintenance of National Highways network to global standards and to meet

user’s expectations in the most time bound and cost effective manner, within the strategic

policy framework set by the Government of India and thus promote economic well being and

quality of life of the people.




The NHAI has a Chairman, 5 full time Members, Chief General managers, General

Managers, Deputy General Managers, Managers and secretariat staff at head office and at

Project Implementation Units (PIU) spread all over country from technical, financial and

administration. NHAI is one of the agencies of the Ministry of Road Transport and

Highways and is responsible for development and maintenance of the National Highways

assigned to it.

NHAI is financing its projects by a host of financing mechanisms such as securitization of

cess on petrol and diesel given by central government, market borrowing, budgetary grants

from central government, loan form international funding bodies, toll on completed National

Highways, special purpose vehicles (SPVs) with other stake holders, and award of projects

on build operate and transfer basis (toll and Annuity)

CHAPTER 2: EXISTING FEATURES OF THE PROJECT HIGHWAY

The Project Highway is situated between km 323.475 (end of Etawah bypass) and

km 483.687 (end of Kanpur bypass (elevated) section) of Delhi- Kolkata section of NH-2,

with km 0.00 at Delhi. The total length of the Project Highway is 160.212 km.

Location Map of the Project Highway




The construction of 4 Lane Highway was done in following three packages completed during

the period 2001- 2007.

1. Section I– C (km 323.475 to km 396.133) 72.660 km long.

2. Section II- A (km 396.133 to km 457.498) 61.365 km long.

3. Section III- B (km 457.498 to km 483.687) 26.290 km long.

The Project Highway passes through plain terrain in its entire length. There are a number of

settlements along the Project Highway. The section has habitation and encroachment in

some stretches. The existing Right of Way varies from 23 m to 80 m and is generally

between 40 m to 60 m. The carriageway width is 7.0 m with 1.5 m wide paved and 2.0 m

wide earthen shoulders for either side traffic. The existing road has both the flexible and rigid

pavement. The height of embankment varies from at ground level to about 10 m near

approaches to structures and other places. The 85.958 km long service road, with width

varying from 4 m to 7 m, has been provided on both sides, though not continuous. The width

of raised median varies from 1.5 m to 5.0 m in different stretches.

There are three major bridges, 17 minor bridges and 279 box/ slab/ pipe/ culverts on the

Project Highway. Since one carriageway of the Etawah- Chakeri Section is new, the

structures are in good condition. However, in the old carriageway, the structures need some

rehabilitation measures/ reconstruction. Two railway line crossings exist at km 465.890 and

km 478.540. Both ROBs have two lane carriageways for Main Highway and two lane

carriageways for service road on both sides. A number of grade separators in the form of

pedestrian/ cattle crossings and vehicular underpasses as per details given below, exist along

the Project Highways.

There are a number of major and minor at grade junctions. Utilities like telephone cables,

OFC lines, water pipe lines and electric lines run along the Project Highway.

There is mixed traffic on the Project Highway comprising of trucks, buses, cars, two-

wheelers, non-motorized vehicles etc. The Consultant had carried out the traffic surveys at

km 353.500, km 399.550, km 466.000 (elevated), km 466.000 (service road) in March 2010

and the second set at km 352.500, km 438.000 and km 466.000 (service road and elevated

portion) in June 2010. The total vehicles at these locations in June 2010 are under.

CHAPTER 3: ENGINEERING SURVEYS AND INVESTIGATIONS

The needed data was collected from the office records and through additional surveys, such

as topographic surveys, digital still photography, physical surveys, and traffic surveys

conducted by the Consultant. Two sets of traffic volume counts were carried out for 7 days,

both for up and down directions, at four locations viz. km 353.500, km 399.550 and km

466.000 (elevated) and km 466.000 (service road) in the months of March 2010 and then at

km 352.500, km 438.000 and km 466.000 (both on elevated section and service road) in June

2010. Details of traffic surveys are presented in Chapter 4 of the Feasibility Report.

Pavement Condition Survey and Roughness Measurement

The pavement condition and road inventory surveys , roughness measurement and the

structural evaluation of the pavement, both by Benkelman Beam deflection and test pits,

were carried out in February – March 2010. Details of pavement evaluation studies are given

in Chapter 5.




Material and Geo-technical Investigations

A number of borrow areas of aggregates and soils, having adequate quantity and appropriate

quality of materials for 6 laning work, are available. The samples collected from the borrow

areas were subjected to detailed laboratory studies. It is seen that good quality soil and

aggregates are available within reasonable leads for the widening work.

Inventory and Condition Survey of Bridges and Culverts

The needed surveys for all the structures on the Project Highway were conducted in

January – February 2010. Based on visual inspection, deficiencies in the structures were

identified. The details of the structures are given in Chapter 6.

Public Consultation Meetings

The Public Consultation meetings were held at three places, viz (i) Bakewar (ii) Auraiya and

(iii) Rania during October and November, 2010. The meetings were held with the general

public, elected representatives of Gram Panchayat, Zila Parishad and other key personnel of

the area. The NHAI officials also participated in the meetings. The participants were

explained of the proposals planned in 6 laning work. The suggestions received from them

generally in the form of safety considerations have duly been taken in the report.

CHAPTER 4: TRAFFIC STUDIES AND ANALYSIS

Traffic studies were undertaken for determination of the travel characteristics, and for future

traffic projections. The following surveys were conducted in the field:

• Classified traffic volume count survey for 7-days at four locations, twice

• Origin-Destination survey for 24 hours at 2 locations, once

• Turning movement survey for 12 hours at four locations, once.

• Speed and delay survey on the project corridor, once.

• Axel load survey for 1-day at two locations, once.

From the various surveys, the analysis for ADT, seasonal variation, AADT, average journey

and running speed, speed and delay and traffic forecasting was undertaken. Two times traffic

volume counts were conducted in March 2010 and June 2010. The second survey has shown




an increase of about 30 to 50 percent in toll able traffic over the first count. The vehicles

damage factors at locations km 353.000 and km 400.00 vary between 2.63 and 6.44 for the

two directions of traffic. The axle repetitions for various sections of the corridor calculated

for the 20 year design period are estimated to be in the range of 69- 100 msa. The average

travel speeds for different sections are found in the range of 69 and 77 km per hour.

The traffic growth rates were worked out by applying various techniques. The future traffic

projections have also been done by assuming a uniform growth rate of 5 percent for all

categories of vehicles.

CHAPTER 5: PAVEMENT EVALUATION AND PRELIMINARY DESIGN

Pavement evaluation was done to assess the functional and structural condition of the Project

Highway. It has been 4-laned recently. Except for rutting in some stretches, no major

distress was observed. Roughness measurement for each lane and each direction of the road

were undertaken with duly calibrated Fifth Wheel Bump Integrator. The riding quality is

generally very good with roughness levels varying between 1300-2500 mm per km.

However, at a few locations, riding quality is not good with roughness levels varying

between 2500-3000 mm per km. From km 400 onwards the roughness levels are higher in

the Etawah- Chakeri carriageway (LHS).

The structural capacity was evaluated with Benkelman Beam. The Project Highway was

divided into homogeneous sections based on the condition survey and deflections were

measured in one km stretch of each homogeneous section of about 10 km length. The data

was analysed for working out the overlay requirement on different stretches. Further, 30 test

pits were excavated in both the carriageways, with a view to examine the thickness and

composition of constituent layers of existing pavement and to evaluate the sub-grade

conditions. The pavement thickness varies from 790-975 mm for the flexible pavement and

560-700 mm of the rigid pavement for the main carriageway and 730- 1060 mm for the

service road. The test pits were excavated at pavement shoulder interface. The sub-grade

compaction is in the range of 70 to 97 per cent of the laboratory density for main carriageway




and 86 to 94 percent at sub grade level. The soil is generally good, yielding 4 days soaked

CBR of 4 to 13 percent at 97 percent density.

Preliminary Pavement Design

(i) Main Carriageway

Based on the traffic for the 20 years life, the pavement composition has been worked out for

different stretches. Since the traffic with 6-laning gets distributed further over the

carriageway width, the existing thickness provided is adequate. It is proposed that additional

lane shall be provided with flexible/ rigid pavement, with paved shoulders, having similar

specifications as that of the existing carriageway. The following composition is

recommended for sub-grade of CBR 8 percent to match with the existing crust.

a) Flexible Pavement

50 BC + 160 DBM + 250 WMM + 370 GSB

b) Rigid Pavement

320 PQC + 150 DLC + 150 Drainage Layer

Further, an overlay of 50 BC is required by the year 2010 over the existing carriageway.

(ii) Service Road

The crust of the service road has been designed for 10 MSA traffic. The widening of service

road/ new construction shall be done with sub-grade of CBR 8 percent and provided the crust

as under:

40 BC + 60 DBM + 250 WMM + 200 GSB.

Further, an overlay of 40 BC is proposed on existing service road to match with the

bituminous requirement for 10 MSA traffic.

CHAPTER 6: CONDITION SURVEY AND ANALYSIS OF STRUCTURES

Relevant GADs as per DPR, GFC and As-built drawings were collected from NHAI and

supervision consultant and reviewed. There are a number of river and drainage crossings in

the Project Highway and all of them have been bridged. There are 3 major bridges, 17 minor

monitor the movement of traffic and for giving requisite information to the users.

CHAPTER 8: DESIGN STANDARDS

The widening to 6 lanes standards from a present 4 lane road is to be done as per provisions

of the IRC: SP: 87-2010 ‘Manual of Specifications and Standards for Six Laning of National

Highways through Public Private Partnership’ and the NHAI Guidelines on BOT (Toll)

projects. However, some deviations have been made keeping in view the site conditions.

CHAPTER 9: PROPOSALS FOR WIDENING AND RETROFITTING

Major Bridges

The existing major bridges at km 421.700 and 450.587 have 2 lanes of carriageway for each

direction of traffic and are in fair condition. They are proposed to be retained after

rehabilitation. These bridges have well foundation, which cannot be widened so new bridges

with footpath are proposed on outer side of existing bridge either on one side or both sides as

per requirement of manual and considering site constraints.

The third major bridge is at km 467.400 has 2 lanes of carriageway for each direction of

traffic in main carriageway along with service road bridges on both sides. The bridge is not

proposed to be widened as it is on pile foundation and a part of existing elevated section in

Kanpur whose approach is of RE wall.




Minor Bridges

There are 17 existing minor bridges on the project highway. All the bridges have 2 lanes of

carriageway for each direction of traffic. The bridges in fair/ good condition are proposed to

retained after rehabilitation. Existing bridges are with well/pile foundation or T-beam type

superstructure which cannot be widened so new bridges with footpath are proposed on outer

side of existing bridge either on one side or both sides as per requirement of manual and site

constraints. There are 5 bridges on LHS, in poor condition, and are proposed for

reconstruction, and 3 bridges on Kanpur bypass (elevated) not proposed for widening since

their approaches are on RE wall.

There are 3 minor bridges presently existing on service road at 3 locations for each direction

of traffic. All the bridges are in fair/ good condition and are proposed to be retained after

rehabilitation. Additional minor bridges for service road are proposed at 5 locations for

between km 323.475 to km 460.467 and the remaining 24 culverts exist on Kanpur bypass

(elevated) section. All the 255 culverts between km 323.475 to km 460.467 are proposed to

be widened, to match roadway width, after rehabilitation. Remaining 23 RCC box and 1 pipe

culvert in Kanpur bypass (elevated) section are not proposed to be widened as proposed

roadway are kept same as existing. All the culverts on Kanpur bypass (elevated) section are

to be retained after rehabilitation.

Grade Separators (Vehicular Underpasses)

There are 23 existing grade separators (vehicular underpasses). All are proposed to be

retained after rehabilitation since the approaches are of RE wall and cannot be widened.

Additional 18 grade separators (vehicular underpasses) of 3 lane carriageway have been

proposed on the project road.




Pedestrian Underpasses / Cattle Passes

There are 9 existing Pedestrian Underpasses / Cattle Passes. Out of these 8 are proposed to

be retained without widening after rehabilitation since the approaches are of RE wall. The

PUP at km 413.453 is proposed for widening on RHS with 3 lane carriageway with paved

shoulder and at km 437.570 existing PUP is widened on both sides. Additional 25 Pedestrian

Underpasses / Cattle Passes of 3 lane carriageway both sides have been proposed on the

project road.

Rail Over Bridges (ROBs)

There are 2 ROBs at km 465.890 and at km 478.540 on main carriageway and service road

on both sides. The ROBs are not proposed to be widened as these are part of Kanpur bypass

elevated section whose approaches are of RE wall.

Foot Over Bridges

Four new Foot Over Bridges (FOBs) have been proposed at locations km 324.600,

km 384.900, km 425.400 and km 444.200

of new road, and strengthening/ widening of the existing road.

CHAPTER 10: ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT

The Project Highway passes, primarily through agricultural area. The water quality is good

and the noise levels are low. The noise may be an irritant in city areas mainly Rania during




the construction phase. There is no ecologically sensitive area and forest falling along the

highway. Some of the recently planted trees within the corridor of impact area are likely to

be affected, which shall be taken care by transplanting of younger plants and compensatory

afforestation. Some religious places/ other structures which are located near main

carriageway/ service road and shall be affected during 6 laning.

CHAPTER 11: PRELIMINARY COST ESTIMATE

Cost estimate has been prepared for widening the existing 4 lane Project Highway to 6 lane

divided dual carriageway. The unit rates have been taken from the Schedule of Rates

published by the Uttar Pradesh PWD for the year 2010. For some of items, the prevailing

market rates have also been taken for estimation purpose. The cost of civil works for the

project is Rs. 1205.91 crores, as per details below.
