6 NOTES ON SCHEDULE OF RATES CANAL CROSS DRAINAGE WORKS FOR THE YEAR : All notes under General Notes on Schedule of Rates and Notes on Lead, Lift, Loading and un-loading Charges are applicable to Canal Cross Drainage Works also to the extent they are relevant. 2. Unless otherwise specified the basic rates are inclusive of all lifts. 3. Unless otherwise specified the basic rates are inclusive of standard finish required for concrete surface. 4. The basic rates for concrete items include cleaning the top surface of previous lift and providing cement mortar layer before placing concrete for next lift. The proportion of cement mortar shall be same as that of mortar portion in concrete. 5. A weightage of 25 percent over the rates in the SR is permissible for all items of works involved in the modernization of canals and which are to be carried out during the canal closure period of about 3-4 months and less. In the estimates for modernization, the items of work shall appear based on the rate in SR without the permissible weightage. Below the respective items, the weightage permissible for the item is to be included. Further, the payment of weighatage is permissible only when the contractor completes a minimum of 90 percent of the work entrusted in a single closure period. Failing which the contractor foregoes the advantage of weightage. Payment of RA bills shall be made at rates excluding the weightage. It is only in the last RA bill / final bill, payment for weightage is to be released subject to above condition. 6. Cement content specified for cement concrete works in the item description is based on theoritical design mix computations and is exclusive of wastage and requirement for any incidentals. The actual cement content may vary based on trial mix studies. A suitable clause shall be included in tender for regulating payment for any upword or downword variation in cement content. 7. The quantities of materials including wastage, requirements for incidentals etc., for working out additional lead charges shall be as per the statement of requirement of materials under this section. 8. The basic rates are exclusive of cost of site clearance and river diversion arrangements such as coffer dams, bunds, diversion channels etc. Separate item rate or lump-sum provisions, wherever required, may be included in the estimate for these works. 4
