Dear All,

In case the RCC Roof of a building changes from flat roof (as per bid/ tender awarded to the contractor) to 1:3 sloping roof (as per construction drawing issued to the contractor), what claims can the contractor have due to the change of roof from flat to sloped?

If you go by CPWD DSR (Delhi Schedule of Rates), the rate of RCC for roofs of slope more than 15 degrees is higher than that up to 15 degrees. The detailed analysis of rates of these items is given in DAR (Delhi Analysis of Rates). The difference in rates is on account of the extra labour for laying concrete on sloped surface. You can work out the unit rates for both the cases using your local market rates and find the extra cost involved (difference) for sloped roof, if you want to go by a recognized method.
The relevant pages of the DAR 2016 enclosed.

Dear Er.Anurag Sinha

In addition to the valuable information in the reference cited by Er.E.S.Jayakumar, the following may be considered

The contractor can also make a claim for the inclined shuttering which may require taller props and more labour

If the slope is larger than 30 degrees, top shuttering will become necessary to ensure good quality concrete and this can lead to further increase in costs
