PART-III

BUILDINGS & ELECTRICAL ITEMS

GOVERNMENT OF ANDHRA PRADESH, ROADS & BUILDINGS DEPARTMENT

STANDARD DATA USER GUIDELINES

PREAMBLE

1. The existing AP Standard data for various constructions items are based on observations made

several decades back, mostly utilising eployment of machinery was at the barest minimum. The

Board of Chief engineers have been adopting almost the same data, duly modifying the rates of

labour; materials, hire charges of limited machinery, every year. The advent of construction

machinery and its usage in construction industry has changed the structure and methodology of

data formulation & rate structure and hence, the present estimation of work item rates are not

reflecting ground reality. The CWC(Ministry of Irrigation) has also recommended that where

standard or schedule of rates are revised or where is necessary to do so, the primary guiding

principle should be escalation in labour and material cost and not on trend of rates quoted by

contractors. But the above recommended principle is not being followed by the Board of Chief

Engineers in Andhra Pradesh.

2. Government, in GO 7326 (GAD-GPM& AR) Dated 26-10-05, has observed that the age old

Standard data requires revision and updation with reference to the latest machinery and

contemporary practices and has constituted a High Level Committee to advise on updating and

revision of standard data and schedule of rates. The work has been taken up by CGG and SPIU-

irrigation. The secretary (Irrigation ) is the member- convener of the committee Accordingly the

data has been revised adopting the procedures and guidelines given by CWC, Report on

committee on cost control of river valley Projects, BIS specifications, NHAI, MORTH, MORD, CPWD

and Government of Karnataka and revised data and formulated schedule of rates for all

infrastructure Departments (I&CAD, R&B, PR and PH). The team of senior engineers interacted

with the S.R Committee of Karnataka on implementation and improvements needed. For irrigation

works the data pattern as adopted by Karnataka has been considered and for other Departments

the data adopted by MORTH,MORD and NHAI etc., is adopted

3. Sequence followed in revision of standard data is,

(a) The first step is the revision and formulation of standard data for each work

component

(b) The second step is to work out the details of inputs. This enables to generate the unit

work item rates, by incorporating the use rates of machinery, materials, labour charges

and other supplementary parameters

(c) The third step is to develop software tool to generate unit rate using the software

(completed for irrigation works by the SPI Unit of Irrigation)

4. The Detailed draft data was communicated to all the HODs and interacted through many

seminars and discussions and incorporated the relevant features.The Board of chief engineers in

their meetings have recommended for acceptance to the data formulated and schedule of rates.


3

It was proposed to examine the recommendations on important parameters, to refer to high level

committee, for their specific recommendations for adoption, as they are common to all

departments. The committee made in depth study on the methodology and systems followed by

the reputed National organizations and other States and made detailed deliberations with HODs

and representatives of Builders Association of India and made recommendations to the

Government, on adoption of such parameters in A.P.

5. The Chief Secretary held a detailed discussions on 04-07-2007,with the Secretaries of the

Departments and Heads of Departments.

B. GUIDELINES 1) The Revised Standard Data is formulated under four Parts which are applicable to all the

Engineering Departments and other Organisations.

PART -1: Irrigation& CAD (Dam and Allied Works, Canals And Allied Works, Canal C.D.

Works, Tunnels and Allied Works, Preliminary and Maintenance Works, Hydraulic

Gates and allied works and Leads and Lifts applicable to all Departments

PART -2: Roads and Bridges

PART -3: Buildings including Electrical Works

PART -4: Drinking Water Supply and Public Health (ONLY FOR WORKS DONE BY MANUAL

MEANS)

2) Brief description of item of work. :

Brief description of the item of work to cover all important aspects of the work included in the in

the Data . On reading the item description, the user should be in a position to assess the various

cost components involved in the work.

3) Data for assessing quantities :

The data reflects various assessments / assumptions made in arriving at the quantities of

materials, machinery, labour and other in-puts. In case of plants and equipment the output of

main plant is worked out and the requirement of all other inputs and assessed to match the

output of the main plant. Cycle time of operations is the criteria for assessing the output of

equipment. Generally the equipment manufacturers furnish the output of machinery under ideal

conditions of working. Suitable job and management efficiency factors are considered while

working out the average output of machinery under field conditions. In case of combination of

machinery and manpower the assessment of manpower shall match the output of machinery.

Though cycle time of operations is the criteria for hourly / daily out-put of machinery work-force

,the actual progress of work depends on several other factors such as power interruptions, minor

break-downs, time for meals and other needs of work-force, stray rains etc. Therefore, it is the

general practice to consider 50 minutes as the actual working time per hour for working out the

hourly / daily out-put of machinery / work-force.CWC / BIS guide-lines stipulate the actual working


4

hours for the purpose of equipment planning and utilisation. The daily out-put is computed duly

considering the actual available working time and feed back from the field.

For gate and hoist works it is the general practice to specify the quantity of work in

terms of number of sets of embedded parts / gates. The requirement of machinery and work-

force for cutting, bending, fabrication, erection, painting etc., is assessed to commensurate with

the task involved.

The data for gates and E.M. Parts is arrived per Ton quantity.

The data for Hoists and Gantry Cranes is worked out on the basis of capacity in tonnage

4) The lead and lift charges provided in PART-I (B) are generally applicable and common to all

Departments. Any item is not covered in this part, the rates as provided in the data of the

relevant works may be adopted in preparation of estimates.

5) The basic material inputs needed for all works are listed and incorporated in the data. The

requirements are analyzed and the specifications adopted shall confirm to Standards published by

the BIS.

The labour and material rates will be communicated by the Board of Chief engineers.

Unless otherwise specified, all material rates shall be inclusive of all taxes, duties, levies,

royalty/seigniorage, transportation and handling costs up to project area.

For sand, gravel , murum, stones , course aggregates etc, the rates are to be fixed for

delivery at Quarry, adding seigniorage ( royality) charges, loading charges by machinery /

manual means and idle hire charges of machinery (as per table under chapter

conveyance or lead and lift charges), as applicable.

For earth/ soil for embankment works from borrow areas, which is not included in the

material list of schedule of rates, seigniorage charges are to be added separately,if

applicable.

For steel, Cement, AC sheets, GI sheets, Hume pipes, wood and stone slabs, the rates are

to be taken prevailing at major commercial centre near project area. The lead charges, as

applicable are to be added in preparing estimates.

The specifications of the aggregates for sizes and gradation and its adoption shall be as

per IS 383.

6) The labour component in the data is mentioned for unit work.

No allowance towards labour importation and labour amenities added extra as they are

included in the recommended overheads.

On Labour Component: Certain additional allowances are added extra to the wages of

labour (,i.e. only on labour component in the work item) in the form of percentage, as

recommended by the Government/Board of chief engineers,due to statutory and other

provisions.


5

However, If more than one area allowances, such as those for (1) Municipalities (2)

Agency / Tribal areas (3) Industrial areas are applicable for a particular situation, only the

maximum out of the allowable percentages is to be allowed.

7) HIRE CHARGES OF MACHINERY:

The machinery and /or group of machinery for items of works and their output has been

worked based on the availability of machinery generally in the market and working in the the

field successfully, duly considering cycle time, idle time, operator efficiency, type of work etc.

The hire charge of a machinery / equipment is worked out based on the guidelines

published by CWC and BIS codes.

For the other machinery not covered by the list, the R&B and other users may adopt hire

charges as recommended by the MORTH.

8) Lead Charges

The high level committee has recommended to adopt, for conveyance by head load, a

minimum lead of 50 meters and additional lead up to 150 meters in the intervals of 50

meters. Beyond 150 meters lead ,only machinery rates are to be adopted.

The basic item rates provided in the schedule of rates include 50 m or 1 km as initial lead

and no lead charges shall be allowed where the source of material is within the initial

lead specified in item rate. Additional lead charges shall be allowed for the lead

exceeding initial lead specified in the item rate.

The lead charges per unit quantity for conveyance of the materials are worked out,and

included in the schedule of rates in increment of 50 m for head load and in increment of

1 km for mechanical mode.

The rates for lead charges by head load upto 150 meters and by machinery up to 5 km,

shall be cumulative and inclusive of lead charges for preceding lead. For lead beyond 5

km the lead charges shall be worked out on per km basis.

9) Loading and Unloading charges for Materials

The following features are considered:

(a) Loading and unloading charges are not payable for conveyance by head load.

(b) Loading and unloading charges are not payable for conveyance by mechanical

means, for disposal of excavated material unless specified.

(c) The rates for unloading of materials except earth, sand, gravel, coarse aggregate,

rubble, size stone and cut stone, are inclusive of stackingwherever applicable.

10) LIFT CHARGES :


6

The data includes initial lift charges of 3 meters ,for materials conveyance by head load,

Additional leads in the interval of 1.0 meters are worked out, as additional labour input

and incorporated in the chapter on Lead and lifts .

Where the conveyance / lifting of material is done by mechanical means, lift charges shall

not be considered, as the cycle time of operation of the machine includes lifts involved.

The data and rates for lift charges is cumulative and are inclusive of rates for preceding

lifts also.

11) Wastage of Materials

Cement : No wastage allowance is recommended towards the quantity of cement

used in works, as the wastage is already included in the input and in major works

bulk quantities are used.

steel : The wastage of steel @ 2.5% is allowed for gates and allied structures. For

RCC works the wastage is @2.5% for the reinforcement rods above 36mm did and

@ 5% for rods below 36mm dia. including overlaps, if they are not welded. If welding

is adopted for the reinforcement rods even for below 36mm dia, 2.5% of wastage is

only recommended.

12) Provision for rate for water:-

The Committee has recommended not considering the water charges in the Irrigation

Project works. But, it may be considered in specific cases as per the site conditions.

13) In respect of RCC works the rate for cement concrete for 1 cum is worked separately for

all grades based on Indian Standards. The rate for ton is calculated separately and to be added

separately in the estimates of RCC works as a separate item.

14) Soil classification: The Committee recommended to allow uniform classification of soils for all

Departments and data is worked out accordingly.

1. All soils 2. Marshy soil 3. ordinary rock ( not requiring blasting), 4. hard rock a. hard rock (requiring blasting) b. hard rock (controlled blasting) c. removable by chiseling(blasting prohibited)

15) Use of Super Plasticizers and Admixtures:

Concrete admixtures such as Air-Entraining Agent (AEA) / Water reducing agent can be

used advantageously for better quality concrete. The high level committee has

recommended adopting for super plasticizers and admixtures at 0.4% on cement for

concrete work as per MORTH standards for batching plants.

16) Contractors overheads, profit and other provisions:


7

High Level Committee has recommended to add 14% plus 4% towards VAT or as

applicable on item rate towards overheads labour including importation and amenities &

contractor profits, which includes various items recommended in MORTH.

This also includes 4% of VAT and should be exhibited separately. In the

agreements, it should be mentioned that it will be reimbursed as per actuals. The

provisions allowed in Go Ms. No. 94, I & CAD, Dt. 1-7-03, need not be added separately.

The overhead charges include the following elements:

Site accommodation, setting up plant, access road, water supply, electricity and general

site arrangements.

Office furniture, equipment and communications

Expenditure on:

Corporate office of contractor

site supervision

Documentation and as built drawings

Mobilisation/ de-mobilisation of resources

Labour camps with minimum amenities and transportation to work sites.

Light vehicles for site supervision including administrative and managerial requirements.

Laboratory equipment and quality control including field and laboratory testing.

Minor T & P and survey instruments and setting outworks, including verification of line,

dimensions, trial pits and bore holes, where required.

Watch and ward

Traffic management during construction

Expenditure on safeguarding environment

Sundries

Financing Expenditure

Sales/ Turn overtax

Work Insurance/ compensation

17) EXCISE DUTY ON SUPPLIES :

In respect of gates, hoists and allied works excise duty is applicable on the value of

fabricated components supplied to site. Excise duty is not applicable on erection charges.

Further, the excise duty shall not be considered in the rate analysis on material

component, as basic material rates are inclusive of excise duty.

Therefore, excise duty is considered in the rate analysis only on

machinery and labour components required for fabrication of gates and hoists at the

central fabrication yard. It is difficult to determine the machinery and labour components

separately for fabrication and erection.


8

For the purpose of computation of excise duty to be included in the rate analysis the

machinery and labour components may apportioned at 75 % for central fabrication yard

and 25 % for field erection and commissioning. Therefore, 75 % of the machinery and

labour components may be considered for assessing the extent of excise duty to be

added in the rate analysis.

18) DEWATERING & DESILTING:

The High level committee considering the local conditions of rainfall / seepage has

recommended towards de-watering and de-silting at 3 percent on the relevant work

component for which dewatering is required.

It is also proposed as per CWC guidelines; to keep a condition in the agreements shall be

incorporated, to fix a ceiling of 5% in extreme cases, with the specific approval of chief

engineer/Government.

19) Computerization of Data:

A software program is developed by the SPI Unit(Irrigation), which facilitates automatic

changes and generation of unit rates, based on basic input rates of Labour, materials and capital

cost of machinery.

A soft ware tool is also developed for auto preparation of estimates based on in put

quantities.

Other Departments are also advised to develop such program.

20) For each chapter separate additional details are incorporated for clarity.

The board has to assess and incorporate only the three basic inputs required to generate unit work item rates as below. Basic rates of labour: Wages of labour commonly required in execution of works has to be arrived and incorporated in the schedule of rates ( Basic Input Of Labour Wages), without adding extra towards area allowances ( like municipality allowance, tribal area and ghat road allowances etc, which shall be added to the rates where applicable in the form of separate percentage as explained in the preceeding paras. The rates shall be the prevailing daily rates in the State and shall not be less than the minimum wages fixed by the Government from time to time. Materials rates: The basic input material rates common to all departmental works are listed out and incorporated (in the chapter Basic inputs) The material specifications adopted shall confirm to Standards published by the BIS The Prevailing market rates for all basic input materials shall be obtained from the major commercial centers near the project areas. Average of the rates, ignoring freak rates, shall be reckoned as the prevailing market rate. Unless otherwise specified, all material rates shall be inclusive of all taxes, duties, levies, royalty, transportation and handling costs up to project area. For sand, gravel, murrum, stones , aggregates etc, the rates are For delivery at Quarry including seigniorage, loading charges and idle hire charges. For steel, Cement, AC sheets, GI sheets, Hume pipes, wood and stone slabs, the rates prevailing at major commercial centre near project area has to be adopted. Use rate of machinery: The third parameter for incorporation in the Basic Inputs, is the use rate of machinery. To arrive at the use rate of machinery, the inputs to be incorporated are

The list and capital cost of machinery required to be used in the construction activity, The rate has to be obtained from major manufacturers and outlet sources and the rate shall be the current market price inclusive of all taxes, duties and freight charges.

The prevailing fuel charges of petrol and diesel are ascertained and average rate adopted

Borrow rate of interest as fixed by the Government/competent authority be indicated.

For the other machinery not covered by the list, the R&B and other users may adopt hire charges as recommended by the MORTH b) The Chairman, Board of Chief Engineers or competent authority appointed by the Government, based on the approved basic inputs, load the above three basic parameters in the software program. The unit rate of all works including hire charges of all machinery will be generated automatically for adoption. He shall communicate the uniform Schedule of rates arrived from Standard Data, to all users for uniform and direct adoption in all infrastructure Departments, as applicable
