FOREWORD TO THE FIRST REVISION I have great pleasure to present the first revised edition of the Standard Data Book for Analysis of Rates for Road and Bridge Works. The Standard Data Book for Analysis of Rates for Road and Bridge Works was first brought out by this Ministry in the year 1994. Since then analysis of rates and estimates for National Highway Works are prepared on the basis of the Data Book. This scientific approach provides for uniformity in inputs for various items of works, besides standardization in, nomenclature. Further its compatibility with the specifications of work is ensured, which had been changed to equipment intensive construction in around 1985 from labourintensive 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 other than National Highways.
• •• _.
However, a need had been felt for revision and updation of the Standard Data Book on account of the following: (i) (ii) (iii) ("IV) (v)
(vQ
Technological upgradation as per currently revised MORT&H Specifications for Road and Bridge Works published 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 in project 'size. Inclusion of new Chapters on Concrete Pavement, Gao-synthetics, Reinforced Earth and Maintenance of 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 would not 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 express my appreciation of SlShri S.C. Sharma and C.C. Bhattacharya, former DG(RD) & AS for their valuable guidance. 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 and Shri 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 Highway Engineers. The Data Book, however, needs to be updated periodically with changes of technology and environment. The Ministry would, therefore, welcome the feedback/suggestions from users, so that any further amplification/modification/updating may be attempted in due course.

For the purpose of calCulation of overhead charges, the projects are categorized into 2 types as under and overhead charges, provided as indicated against each. Category 1: Cost up to Rs. 50 crores
10 percent
Category 2: Cost above Rs. 50 crores
8 percent
Contractor Profit:
10 per cent of cost of works
Contractor profit is also added on overhead charges.
5.
Basic Inputs Basic inputs are only given in the standard data book. The rates for material and labour are to be obtained from local authorities for thlil area where the project is located.
6.
Plants and EqUipment
6.1.
A dozer is proposed for excavation where cutting and filling for the roadway is within 100 m. For longer leads, a combination of hydraulic excavator and tipper is proposed.
6.2.
Keeping in view the job and managerial factors and thlil aglil factor of machines, the output of plant and lilquipment is taken approximately 70 per cent of thlil rated capacity given by manufacture under ideal conditions.

ContractorwiJl make his own arrangements tor borrowing earth. However, compensation for earth taken from private land has been inclUded in the rate analysis for construction of embankment with borrowed earth .• The reqWrlll1lt!nt of machinery has been worked out assuming effective working period of 6 hours per 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. This causes 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 working parties including machines due to congestion caused by pedestrian traffic, local road side venders, parking of vehicles by the road side, encroachments by the shopkeepers and local shops who make use of the berms of the road in front of these shops and unauthorized conversion of road berms into mini local market. The output of manpower and machines is SUbstantially reduced due to factors mentioned above. c) Cost of living in urban areas is comparatively more reSUlting into higherwages.
IIIi
d) .Attimes, work is executed during ni';jhttime due to heavy traffic during day lime: This involves extra expenditure by way of making arrangement for lighting and special transport for working parties due to odd hour.

: 4)
Preamble: 1. The provision of tipper has been made in hours where lead is known like disposal of the materials upto 1000 m. In case where lead is variable like carriage of hot mix or concrete mix from plants or earth from borrow areas, provision has been made in terms of tonne-kilometer (t-kml, which can be adopted as per actual conditions. 2.
Provision has been made for a tractor trolley instead of tipper where dismantled materials of sorts or material having more volume as compared with weight are required 10 be transported. This arrangement will be economical.
3.
The cost of carriage wiUvary depending upon the riding surface of the road. Provision has accordingly been 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 actual situations.
5. Where loading is done by mechanical plant like HMP or batching plant and there is automatic loading in tippers, provision of loading and un-loading has been made at rate of 10 per cent of cost of carriagEf to account for time taken by the tipper for getting loaded at the plant and un-loading in .the paver or otherwise 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 their own 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 carriage including loading and unloading or the rates for supply at site depending upon system being followed at particular locations. These rates should be compared with the rates for own crushing and carriage by the construction agency.

Chapter-3 Earthwork, Erosion Control and Drainage Preamble: 1. The rates have been analysed using mechanical means. Manual means for certain items have·also been provided which can be used for areas inaccessible to machines and for small jobs. 2.
In the rate analyses of earthwork, only compacted volume of earth has been considered.
3.
Rates have been analyzed for average working conditions.
4. Average achievable outputs of machines have been considered taking into account job and management factors. 5.
Cutting by dozer hal? been proposed where the cut earth can be utilized for filling for embankment withiila lead of1 00 m. A dozer can economically push the earth upto a distance of 100 m.
6. Where lead for transporting of earth is more than 100 m, excavator and tipper have been provided. 7. A water tankerof6
KL capacity which is commonly used atcoostruclion sites has been considered.
8. The rate caters for disposal of unsuitable $oil only upto a distance of 1 km. The cost of transportation beyond the initial lead of 1 km will be paid separately based on tonne-kilo mete rage. . 9. The replacement of unsuitable soil by suitable soil shall be included separately in the estimate. The rate analyses for removal of unsuitable soil does not provide for replacement by suitable soil. 10. Incases where embankment is constructed with earth taken from roadway ,the cost of depositing the earth at the siteofernbankment is already included in the disposal of excavated earth. 11. For narrow and restricted areas, plate compactor has been proposed for compaction to achieve the desired density. 12. For small jobswhere loading and unloading is required to be done manually, tractor - trolley has been . proposed for carriage instead of a tipper. 13. In case excavated rock is found suitable for incorporation in works, suitable credit for the available rock shall be given. 14. The possibility of using the blasted rock fragments for backfilling behind structures or backfilling of foundation pits or filling in medians I separators or use in service road shall be examined before proposing disposal of excavated rock. 15. In case of hill roads, the cut earth can be pushed down the valley in case there is no objection. In that case, cost of disposal is not required to be provided.

18. Ally work involved for water courses at culverts (Clause 312) will be priced under respective iterris, like, excavation, grubbing, clearing, etc. for which rate analyses have separately been made. 19. In the case of embankment made from earth taken from roadway cutting, the input of dozer for spreading earth can be deleted as the same is already provided in the cost of excavation. 20. Earth excavated from drains can be used in roadway berms. Hence, carriage for disposal of same not provided.

21. In the rate analyses of some items, the quantities ofsub-items involved in that analyses, like, excavation for foundation, foundation concrete, painting, lettering, etc. have been given. The rates for such items shall be taken from relevant chapters where the same have already been analysed. 22. In case of rock fitl embankment, it is assumed that material is available at site from rock cutting. 23. The itemdfpreparationand surface treabnent offormatior\ (Clause 310) is requlred to be added in the cost estimate only if there is substantial time lag between completion of sub-grade and laying of subbase. As this item is incidental to Works, it is not required to be inclOded in BOa. 24. The items filling behind abubnents and wing wall and provision of filter media has been included in Chapter-15. 25. Excavation for structures beyond the depth of 3 m has been included in Chapter~12.

In case the earth cutting is done by dozer and pushed for filling in the embankmen~ the input of dozer in the cost of embankment shllll be deleted as the same is already provided in the cost of excavation. However, if the earth is dumped by tippers from roadway cutting, the input of dozer for spreading is required to be provided.

Quantities of materials provided are approximate and are meant for the purpose of estimating only. Actual quantities shall be as per mix design.
2.
For construction of sUb-base, two altematives as under have been provided : a. b.
Mix in place method Plarit mix method
3.
Although plant mix method has not been provided in the MoRT&H Specifications, it is actually being adopted by some of the contractors who are holding the mixlng plants to get better qualilyof mix. llis also found economical as it can achieve much more progress. It is recommended that this .point may be kept in view during future revision of specifications of sl!b'base.
4.
In the case of improvement of sub-gradewith lime stabilization, soil is assumeq to be available and has not been provided for. Only lime hasbeeri catered. In the case ollime stabirlzation of SUb-base, so~ has been provided to fohn the sub-base.
5.
In the case of medians, separators and footpaths, plate compactor has been catered for compaction due to restricted space.
6.
It has been assumed in the case of crushed cement concrete sUb-baseibase that during the process of dismantling, 25 per cent of aggregates will get segregated and only the remaining will have to be brOken/crushed from dismantled concrete slab portions. Transportation of materials has been catered . from place of dismantling to work site. In case,site is the same, transportation cost can be deleted.
7.
Separate rate for penetration coat over top layer of crushed cement concrete base has been provided, as this item is optional.
8.
While providing for the rate of materials, detailed local enquiries should be made and prevailing market rates ascertained from concemed suppliers in the area keeping in view the location of crushing plants and lead involved.
9.
The rate analyses for crushing of aggregates has also been inclUded in Chapter-1. The cost of procured aggregates and crushed aggregates by own crusher should be compared and economic altemative adopted. It has generally been observed in practice that contractors are setting up their own crushing plants where quantities of aggregates are large especially for projec:s above RS.50 crores.
10. The quantity considered in the output is the compacted quantity. The quantities of aggregates provided In the rate analysis under the head material are the uncompacted quantities.

Cha,pter-6 Cement Concrete Pavement
1. High capacity batch mix plants of 75 cumlhour (effective output) has been considered in the rate analysis of cement concrete pavement works. 2. While tippers have been provided for transpOrtation of dry lean cement concrete and rolled cement concrete, transit truck mixers have been considered for the cement concrete pavemenl 3.
super plasticizer admixture has been provided to improve workability with reduced water cement ratio.
4.
Cement 43 grade has been catered for the cement concrete pavement i.e., for pavement quality concrete to get higher strength. However, for dry lean concrete, cement of 33 grade may be preferred.
5. While a slip form paver has been catered forthe top layer of con crete pavement,a mechanical paver has been provided for dry lean and rolled cement concrete. 6.
The letter 'L' represents liad in km one way. This will vary hUm project to project and is required to be ascertained at site to provide for the cost of carriage of the mix to the work site.
7.
Materials provided in the rate analysis are for estimating purpose.· Exact quantity of materials will be determined from the job mix formula.
8. Fibre Reinforced
Concrete for Pavements
Fibre reinforcement concrete is a recentdevelopment in the field of cement concrete pavements. In industriarlZedcountries, it has been in use for nearly 20 years now for cement concrete pavements and overlays. In India, it is still on an experimental stage. IRC have already published a code,IRC:SP:461997 for "Steel Fibre Reinforced Concrete for Pavements" which specifies a fibre content of O.75 to 1.5 per cent and brings out the design aspects, material to be used, mix design and construction procedure. Some firms have developed Polypropylene fibres to be used in place of steel fibres. These fibres reducepermeabili~ in concrete and prevent shrinkage cracks, which eliminate chances of corrosion of steel. The organizationsconcemed with the construction of cement concrete pavements and overlays on roads and airfields who have experimented on fibre reinforcement should give a feed back to the Ministry of Road Transport and Highways so that this item can be included in the Specifications laid down by the Ministry and eventually included in the Standard Data Book for Analysis of Rates.

Ultra-
Thin White Topping
Some of the firms in developed countries, in the recent past have come-up with a innovative idea of laying 50 to 100 mm thick overlay of high strength fibre reinforced cement concrete over a dislreSSecl· asphalt pavement They claim to have achieved 2 to 3 times layer durability than asphalt overlays.: There Is a need to gather more detaOs of the work and include in the >speciflcations in case found suitable to conditions in our country.

RIgid and
Cueto change in the properties of materials and type of construction, a gradual changeover from rigid pavement to flexible pavement is desirable to avoid any damage at the butting joint. After provision of an expansion joint in the cement concrete slab, the thickness of slab should be tapered to 10 em over a length of 3 m towards the flexible pavement. The deficiency of thickness caused due to tapering of the slab should be made up by the asphaltic layers. The quantities oHtems should be worked out based on the approved design and drawings and priced as per rates given under respective clauses for cement concrete and asphaltic work. ISS

Substructure Preamble: 1. Although, Substructures are generally constructed in cement concrete, the rate analysis for brick and stone masonry in CM 1:3 have also been included which can be adopted if permitted by design. 2.
The cost of formwork will vary with the height of the substructure. Provision has accordingly been made.
Bridge bearing, being commercial items produced by speclalaed firms with imported technology and parts, the rates for the same are required to be ascertained from the market for the approved design anI! technical specifications.
5.
Filter media and backfilling behind abutments are required to be provided as per guidelines given in
IRC: 78-2000. 6.
Weep holes shall be provided as per Clause 2706 of MoRT&H Specifications.
7.
In case of roller-cum-rocker bearings, only full circular rollers are to be provided.
8. All bearings shall be set truly level so as to have full and even seating. 9.
•
•• •• • • 41
t
3. As the higher grade of concrete is consUier, the provision made for formwork on percentage basis has been suitably adjusted to make it comparable with other grades. 4.
4
For elastomeric bearing pads, the concrete surface shall be levelled such that the variation is not more than 1.5 mm from a straight edge placed in any direction across the area.
10. The bearing should be procured only from those manufacturers who have been pre-qualified by the Ministry of Road Transport and Highways. 11. The bottoms of girders resting on the bearing shall be plane and truly horizontal. 12. For spans in grade, the bearing shall be placed horizontal by using sole plates for suitably designed RCC pedestals.
