FOREWORD TO THE FIRST REVISION

I have great pleasure to present the first revised edition of the Standard Data Book for Analysis of Ratesfor Road and Bridge Works.

The Standard Data Book for Analysis of Rates for Road and Bridge Works was first brought out bythis Ministry in the year 1994. Since then analysis of rates and estimates for National Highway Works areprepared on the basis of the Data Book. This scientific approach provides for uniformity in inputs for variousitems of works, besides standardization in, nomenclature. Further its compatibility with the specificationsof work is ensured, which had been changed to equipment intensive construction in around 1985 from labour-intensive construction methods. The later still forms the basis for analysis of rates adopted by State PWDs,Owing to its merits, ,Ministry's Standard Data Book is being adopted by various agencies for projects otherthan National Highways.

However, a need had been felt for revision and updation of the Standard Data Book on account of thefollowing: (i) (ii)(iii)_. ("IV)

(v)

(vQ

Technological upgradation as per currently revised MORT&H Specifications for Road and Bridge Workspublished in August, 2001.Increased level of 'mechanization.Changes in size, capacity and types of equipment since 1994.Rationalisation in overheads and contractor's profit, based on experience and general increase inproject 'size.Inclusion of new Chapters on Concrete Pavement, Gao-synthetics, Reinforced Earth and Maintenanceof Roads.Incorporation of use of f1yash in road construction.

This revised edition of the Standard Data Book has been finalised in a record time with proper research,analysis and validation, along with a user-friendly Window-based soflYlare for efficient applicaton, This wouldnot have been possible without untiring efforts ofconcemed officers and staff of the Ministry of Road Transport& Highways, Indian Roads Congress and RITES, consultants engaged for the work. I would like to expressmy appreciation of SlShri S.C. Sharma and C.C. Bhattacharya, former DG(RD) & AS for their valuableguidance. I would also like to express my appreciation for commendable efforts put in by S/Shri Jai Prakash,S.K. Kaistha, R.S. Ninan, A.P.S. Sethi, Chief Engineers, Shri S.S. Nahar, Superintending Engineer,S/Shri Sudip Chaudhary and Atul Kumar, Executive Engineers of the Ministry of Road Transport & Highways,Shri G. Sharan, Secretary, IRC, S/Shri R.K Jain & KB. Thandavan, Technical Consultants, IRC andShri S.C. Kakkar, Under Secretary, IRC and S/Shri N. Venkataraman & Harbhajan Singh of RITES.

I ar . sure this Data Book, in its present form, would prove to be very useful to all practicing HighwayEngineers. The Data Book, however, needs to be updated periodically with changes of technology andenvironment. The Ministry would, therefore, welcome the feedback/suggestions from users, so that any furtheramplification/modification/updating may be attempted in due course.

6.3. It has been assumed lhat a water tanl(er would make one trip per hour on an average. Watercharges have flOt'beert inQIUdedfor items Where the Rlquirement is very nominal. It is assumedthat the same would be covered under sundries.

6.4. Output of plant/equipment is considered for the compacted quantities.

6.5. The usage charges for machines include ownership charges, cost of repair and maintenanceincluding replacement of lyres and running and operating charges which includes crew, fuel andlubricants. '

7. Materials

7.1. Quantities of materialsgivenin the rate analysis are approximate for the purpose of estimatingand include normal wastages. ActUal consumption would have to be based on mix design.

7.2. '. The rates fo material shoukBnclude basic costat locations of stone crushers, loading, unloading,cost fo carriage and stacking at plant sites as the case may be.

7.3. The alternative proposal for curshingown aggregate by installing Crusher should be comparedwith procurement of crushed aggregates from the market and proposal found economical may beadopted.

7.4. The specifications of materials shall be govemed by section 1000 of MoRT&H Specifications forRoad and Bridge Works.

8. Labour

8.1. The labour wages should be as per rates fixed by state government.

8.2. One mate 'has been provided for 25 labours.

8.3. Skilled labour include mason, carpenter, blacksmith, mechanics and other trades.

9. Carriage of Materials

9.1. The unit for vehicle for carriage has been taken as under.

a) In hours where lead Is defined inclUding time required tor loading and unloading.

b) In tonne - km where lead Isvariable. The loading and unloading for such cases have beenprovided.separately ,

Where the quantity of material to be transported is small such as dismantled materials and !besame are required to be loaded manually, provision oftraclor-Irolley has been made instead~)tipper.

The clause numbers refer to MoRT&H Specifications for Road and Bridge Works.

Assumptions made have been indicated in respective chapter in the form of notes, where required.

Sundries to cater for unforeseen contingency and miscellan~us items have been added in theoverhead charges ..

Arrangement tor traffic dUringconstruction shall be as per Clause 112 of MoRT&H Specificationsfor Road and Bridge Works.

The supply of materials will be taken either at the location of mixing plant or at the work site asthe case may be.

ContractorwiJl make his own arrangements tor borrowing earth. However, compensation for earthtaken from private land has been inclUded in the rate analysis for construction of embankmentwith borrowed earth .

The reqWrlll1lt!nt of machinery has been worked out assuming effective working period of 6 hoursper shift of 8 hours.

The costof earthwork in urban roads will be comparatively higher due to following reasons: _>.

a) There is mixed traffic on urban roads IikesJow moving hand and animal driven carts, rickshaws,cycles, twoJIhree wheeler apart from the usual vehicular traffic reSUltinginto traffic jams. Thiscauses loss of working time which may be in the range of 10-15 per cent.

b) There is considerable disruption of traffic adversely affecting the efficiency of the workingparties including machines due to congestion caused by pedestrian traffic, local road sidevenders, parking of vehicles by the road side, encroachments by the shopkeepers and localshops who make use of the berms of the road in front of these shops and unauthorizedconversion of road berms into mini local market. The output of manpower and machines isSUbstantially reduced due to factors mentioned above.

c) Cost of living in urban areas is comparatively more reSUlting into higherwages.

d) .Attimes, work is executed during ni';jhttime due to heavy traffic during day lime: This involvesextra expenditure by way of making arrangement for lighting and special transport for workingparties due to odd hour.

10.23. Grade of cement may be adopted as per mix design.

10.24. Quantities of cement in various grades of cement concrete have been taken as per IRC:21-2000"and IRC:18-2000.

10.25. The rates for rigid, semi-rigid and flexible crash barriers have been analysed in Chapter-8.

10.26. The coarse and fine aggregates shall conform to IS:383.

10.27. Certain equipments like road rollers, are required to be available at site for complete period of theshift, though from the consideration of their output, they may be required only for 3 to 4 hours.This is necessitated to match with the output of other associated machines like HMP, Paversetc. in such cases, the hire charges of road rollers have been multiplied with a factor of 0.65 toaccount for the idle period.

10.28. For pricing of RCCsiab culverts, the items given in respective chapters in bridge section may bereftered.

10.29. Wherever electric generator has not been provided to run a plant or equipment, it is assumed thatit is fitted with a diesel engine.

10.30. Some of the firms in the field of construction chemicals have evolved new brands of chemiCals for_ water proofing, sealing of cracks, cementing compunds etc. The m..arketcan be explored to meetsuch requirements.

10.31. Some of majorsteel producing firms have evolved thermo-mechanically treated steel whiCh hasenhanced strength, better corrosion resistance. ductility, weld ability and high temperature thermalresistance. Enquiries frOm these firms can be made on techniCal specifications and use of sue'"products considered in works based on performance in works where these have already beenused.

10.32. Provision of fly ash has been made in embankment construction, sub-base construction and incement concrete pavement.

10.33. The Standard Data Book is for Department use only. It cannot be produced in Court of Law asreference/authority and thus is a privilege document.

Carriage of Materials

Preamble:

1. The provision of tipper has been made in hours where lead is known like disposal of the materials upto1000 m. In case where lead is variable like carriage of hot mix or concrete mix from plants or earthfrom borrow areas, provision has been made in terms of tonne-kilometer (t-kml, which can be adoptedas per actual conditions.

2. Provision has been made for a tractor trolley instead of tipper where dismantled materials of sorts ormaterial having more volume as compared with weight are required 10 be transported. This arrangementwill be economical.

3. The cost of carriage wiUvary depending upon the riding surface of the road. Provision has accordinglybeen made considering surface roads, unsurfaced graveled roads and katcha tracks.

4. Analysis for iOading has been done both for manual and mechanical means for adoption as per actualsituations.

5. Where loading is done by mechanical plant like HMP or batching plant and there is automatic loadingin tippers, provision of loading and un-loading has been made at rate of 10 per cent of cost of carriagEfto account for time taken by the tipper for getting loaded at the plant and un-loading in .the paver orotherwise at site.

6. Although the market rates for supply of aggregates at site are generally taken for estimation purpose,rate for crushing of aggregate'have also been analysed as most of the contractors prefer to crush theirown aggregates in case of large projects exceeding RS.50 crores in value.

7. The cost of ma~\ilrialshall be evaluated considering the cost at crushing plants and cost of carriageincluding loading and unloading or the rates for supply at site depending upon system being followedat particular locations. These rates should be compared with the rates for own crushing and carriageby the construction agency.

Preamble:

1. Various alternatives for machines and materials have been provided. The one that suits a particularsituation and design may be adopted.

2. The Clauses of MoRT&H Specifieatlons, which have been mentioned tor each item, may be referred tordetailed specifications and construclion procedure. The rate analyses mention. only brief description.

3. The machinery and equipment included in various analysis are as per various specifieatlons of MoRT&Hand are mandatory. As perthe present trend,contraetors areprocuring machinery and equipment ofhigher capacily. Provision has accordingly been made.

4. The outputs taken for the construclion equipment are tor the compacted quantities of the relevantitems and not for loose quantities.

5. In case of prime coat and tack coat, minimum quantities of binder indicated in specifications havebeen taken. Adjustment, plus or minus, can be made tor the variation between this quanlily and theactual quanlily approved by the EngineeraflertheprelirTiinarytrials.

6. The items of bituminous works required under maintenance have been added in the Chapter onMaintenance.

7. Tack coat and prime coat, wherever provided, are required to be measured and paid separately.

8. Cleaning of surface is a part of the prime coat and tack coat. As such cleaning of surface has not beenprovided tor bituminous courses as the same is already catered inprimeJtack coat. However, tor thosecases where such coats are not required to be done, cleaning of surface shall be included.

9. It is presumed that tack coat, where required, will be provided immediately preceding the bituminouslayer.

10. Rolling of bituminous courses is required to be done as per Clause 501.6. Provision in the analyseshas accordingly been made. It has been observed during actual praclice at work sites, that theavailabilily of road roller is generally inadequate. As compaclion is the key to good construction, thispoint is being specifically highlighted to ensure that road rollers are deployed at site as per provision inthe rate analyses.

11. Spreading of bituminous materials shall be done by mechanical means except in areas where amechanical paver cannot have access.

12. The source of all materials to be used on the project must be tested and expressly approved by theEngineer.

17. The quantities taken as output of the it\lm in the rate analysis are the compacted quantities and the quantities of aggregates taken under the head 'material'are the un-eompacted quantities for the procurement purposes.

18. The approximate proportions byweigtlt of different aggregates and bitumen CorbyVolume in unavoidable cases) necessary to produce the intended mix satisfying the job requirements and meeting thedesignated Specifications are for estimating purpose only .. The actual quantities should be worked out.on the basis of job mix formula adopted for the job. after working out the same in the laboratory forparticular aggregates and bitumen approved by the Engineer.
