Credit of Old Material : Recovery items: The Rates quoted against recovery items will not be included in the total amount rather it will be deducted while calculating financial statement of the agency. Material obtained from dismantling / scarifying of existing bituminous crust have been calculated taking assumption that 80% of theretical material will be retrieved. The Dismantled / scarified material can be issued for use in any of the item for the work after modification (bringing it to required specificaiton) on approval from the employer. In case it is not possible to use this material on the work, the agency can take away this material. The material can be taken away by the agency at the price quoted by the agency. However, the reserve price is asgiven blew. The rate quoted against recovery items will not be included in the total amount rather it will be deducted while calculating financial statement of the agency:- Bituminous mix material @ Rs. 1502/- P.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.
