Note: - Reinforcement shall be measured in length including hooks, if any, separately for different diameters as actually used in work, excluding overlaps. From the length so measured, the weight of reinforcement shall be calculated in tones on the basis of IS: 1732. Wastage, overlaps, coupling, welded joints space bars, chairs, stay, hangers and annealed steel wire or other methods for binding and placing, shall not be measured and cost of these items shall be deemed to be included in the rates for reinforcement (NS).

Preparation of berms including filling of Earth work, excavation and cutting of earth in all kind of soils including dressing the bank, side slope to given levels and templates after breaking of clouds, including the cost of rolling and watering all allowances for labour hardness wetness irrespective of all lead and lift and including compensation for earth taken from private land, fields etc. and compacted to meet requirement of table 300-2 of MoRT&H specification clause No. 305 and to the entire satisfaction of the Engineer of the work conforming to PWD specification No. 6.2 and 6.3 and 3.2 and the other specification 1990 Ist edition. As per X-section attached at DNIT at Section-9. Note: - No earth work will be allowed to be taken from PWD B&R/ROW except for surplus earth after approval from Engineer.

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 bituminous layer 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 :- (i) Bituminous mix material @ Rs.1250/- 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. Note: - 1)In case of any difference in the unit& nomenclature of any of the HSR items depicted in this DNIT and that given in HSR, the unit and Nomenclature given in HSR shall be applicable. 2) In case of any difference in the unit of any Non-schedule item depicted in this DNIT and the conventional unit of that N.S. item as per practice in this department, the conventional unit as per practice shall be applicable.
