In case it is not possible to use this material on the work, the agency can take away this material. This material can be taken away by the agency at the price quoted by the agency but minimum price to be quoted is limited to reserve price as fixed and mentioned as under:- i) Bituminous mix material @ Rs. 1200.00 per cum

ii) WBM material @ Rs. 621.00 per cum

iii) GSB material @ Rs. 621.00 per cum Note: All quantities of the above materials have been worked out on the basis of theoretical quantities laid on this road. However, agency may visit site before quoting rates and assess the extent of retrieved material. There shall be no measurement after actual dismantling and if material after dismantling is found on lesser side, no claim of agency on this score will be entertained and full recovery on the basis of quoted rate and quantity exhibited in the BOQ shall be made. The reserve rates are minimum rates to be used as base for quoting purchase rate by the agency. No rates below the reserve price will be entertained and reserve price will be considered for all purposes in case the agency quotes lesser than reserve price.
