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 of existing brick work, bituminous layer and granular layers have been calculated taking assumption that 80% of theoretical material will be retrieved. The dismantled material can used in any of the item for the work after modification (bringing it to required specifications) after approval from employer. 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 :-(NS) (i) Recovery of milling material of bituminous @ Rs.1700.00 Per Cum
