Rate Analysis

1. PART-A- RATE ANALYSIS STANDARD DATA BOOK FOR ANALYSIS OF RATES ( S ECOND R EVISION – 2019)

2. A NALYSIS OF RATES The determination of rate per unit of a particular item of work, from the cost of quantities of materials, the cost of labour and cost of plant and machinery required for its completion is known as the Analysis of Rates. The rates of materials and Labour vary from place to place and hence the rates of different items of works also vary from place to place.

3. P URPOSE OF A NALYSIS OF RATES To work out the actual cost of per unit of the items. To work out the economical use of materials and processes in completing the particulars item. To work out the cost of extra items which are not provided in the contract agreement, but are to be done as per the directions of the department. To revise the schedule of rates due to increase in the cost of material and Labour or due to change in technique.

4. I NTRODUCTION O F S TANDARD D ATA B OOK The standard Data Book (SDB) for Analysis of Rates for Road and Bridge works was first brought out by MoRT&H in 1994 and then revised in June 2003 based on Ministry’s specification for Road and Bridge works ( Fourth Revision-2001) and relevant IRC codes/guidelines/circulars. However, a need had been felt for revision and updation of the standard data book on account of the following: Technological upgradation as per currently revised MORT&H specification for road and bridge works in 2013. Increased level of mechanization. Change in size, capacity and type of equipment since 2003. Rationalization in overhead and contractor’s profit , based on use of machineries at various project sizes. Inclusion of new chapter for Box cell structure, Road tunnel works and Environmental & Safety Management and Bio Engineering. Output efficiency of machineries and labour has been considered depending upon the terrain like plain, rolling and hilly. Accordingly two volume i.e., Vol-I for plain/ rolling terrain and Vol-II for hilly terrain of Standard Book are published. The revised edition of standard data book has been finalized with a user- friendly web based software for efficient application use.

5. BASIC APPROACH FOR THE PREPARATION OF S TANDARD D ATA B OOK Labour Materials Plants and Equipment Overhead Charges Contractor Profit Basic Inputs

6. O VERHEAD C HARGES 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. Mobilization/ de-mobilization 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 out works, including verification of line, dimensions trial pits and bore holes, where required. Temporary Diversion with Safety measures. Watch and ward. Traffic management during construction, expenditure on safeguarding environment, Sundries and Financing expenditure. Insurance/ compensation.

7. O VERHEAD C HARGES A) ROAD WORKS Overhead Charges are considered depending upon the size of the projects as under: Civil Works cost up to Rs 200 crores - 12 percent Civil Works cost more than Rs 200 crores and less than equal to Rs 500 crores - 10 percent Civil Works cost more than Rs 500 crores – 08 percent Note: Civil Works cost is excluding GST. B) STRUCTURE WORKS Category 1: New/ Widening of Bridge/ Structure Works - 20 percent Category 2: Rehabilitation of bridges/ Structure – 30 percent •

8. C ONTRACTOR ’ S P ROFIT CONTRACTOR’s PROFIT- 10 PER CENT OF COST OF WORKS IS ADDED ON TOTAL COST i.e., AFTER ADDING OVERHEAD CHARGES.

9. RATE ANALYSIS BASIC INPUTS LABOUR MACHINERY MATERIAL

10. L ABOUR ASSUMPTION CONSIDERED IN SDB :- The Labour wages should be as per rates fixed by state government. One mate has been provided for 25 labours. Highly Skilled Labour includes mason (1 st class), carpenter, blacksmith (1 st class) , mechanics and other trades.

11. P LANTS AND E QUIPMENT ASSUMPTION CONSIDERED IN SDB :- A dozer is proposed for excavation where cutting and filling for the roadway is within 100m. For longer leads, a combination of hydraulic excavator and tipper is proposed. Keeping in view, the job and managerial factor and the age factor of machines as per their utilization in various project sizes, the output of plant and equipment has been considered, however the output of plants is considered approximately 75 per cent of the rated capacity given by manufacture under ideal conditions. The water tanker speed @ 20 km/hr, return speed @ 30 km/hr, spreading speed @ 30 km/hr in soil & 3.0 km/hr, in granular material is considered for analysis. Water charges have not been included for items where the requirement is very nominal. It is assumed that the same would be cover under sundries. Output of plant/ equipment is considered for the compacted quantities. The usage charges for machines include ownership charges which includes depreciation, interest charge, insurance, road tax, cost of repair and maintenance including replacement of tyres and running and operating charges which includes crew, fuel and lubricants.

12. M A TERIALS MATERIALS :- Quantities of materials given in the rate analysis are approximate for the purpose of estimating and include normal wastages. Actual consumption would have to be based on mix design. The rates of material should include basic cost at locations of stone crushers, loading, unloading, cost of carriage and stacking at plant sites as the case may be. The alternative proposal for crushing own aggregate by installing crusher should be compared with procurement of crushes aggregates from the market and proposal found economical may be adopted. The specification of materials shall be governed by section 1000 of MoRT&H Specifications for Road and Bridge Works. Material rates are excluding GST. CARRIAGE OF MATERIALS :- The unit for vehicle for carriage has been in hours where lead is defined including time required for loading and unloading. The unit for vehicle for carriage has been in tone – km where lead is variable. The loading and unloading for such cases have been provided separately.

13. S OME G ENERAL A SSUMPTION I N SDB The clause numbers refer to MoRT&H Specifications for Road and Bridge Works. The supply of materials will be taken either at the location of mixing plant or at the work site as the case may be. Contractor will make his own arrangements for 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 rates of items include cost of testing of soil, materials and works. The hire charges for machinery and equipment are applicable for the year 2019- 2020. It should be updated for subsequent years depending upon the market situation. Grade of cement may be adopted as per mix design. Wherever electric generator has not been provided to run a plant or equipment, it is assumed that it is fitted with a diesel engine. The requirement of machinery has been worked out assuming effective working period of 6 hours per shift of 8 hours.

14. L EAD STATEMENT The distance between the source of availability of material and construction site is known as “Lead ” and is calculated in Km. The cost of conveyance of material depends on lead. This statement will give the total cost of materials per unit item. It includes basic cost, conveyance, loading, unloading and stacking charges etc.

16. L ABOUR R ATES

17. B ITUMEN R ATE The Bitumen rate is changed at every 15 th day of month so that we adopted the basic rate of bitumen from IOCL website from nearest refinery to the project site. The rate of bulk bitumen on website is excluding carriage charges.

18. C EMENT R ATE The cement rate depends upon the location of site. Hence the rate of cement is taken from market.

19. S TEEL R ATE Market Rate for steel will be taken from SAIL website. The rates are updated every month on the website.
