5 NOTES ON SCHEDULE OF RATES CANAL AND ALLIED 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 and Allied Works also to the extent they are relevant. 2. The basic rates are inclusive of finishing, wastage of materials in handling, incidental works, profit, overheads, small tools / plants, hidden cost on labour etc. 3. The basic rates are inclusive of royalty charges payable on materials. 4. The recovery of royalty charges on materials, wherever applicable, shall be as per the guide lines listed under ' General notes on schedule of rates ' and the amount of royalty charges shall be as per the statement of royalty charges included in this section. 5. Unless otherwise specified the basic rates are inclusive of all lifts. 6. For earth / rockfill embankment works 1 km initial lead is considered in the basic rates. As no storing / stacking and re-handling of materials is involved for these works lead charges for additional lead shall be worked out for total lead including initial lead of 1 km and then the cost of first km lead shall be deducted. No loading and un-loading charges shall be added as the additional lead does not involve re-handling of materials. Example : Total lead for soil from approved borrow area : 2 km Initial lead included in the basic rate in the SR : 1 km Additional lead charges : Lead charges for 2 km Rs: Less Lead charges for 1 km Rs: Additional lead charges Rs: 5.80 No loading and un-loading charges shall be added. 7. Cement content specified for cement concrete works in the item description is based on theoritical design mix computations. The basic rate shall be adjusted upword or downword including lead, loading and un-loading charges for any variations in cement content based on trial mix studies furnished by Q.C unit. 8. 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. 9. The basic rates are exclusive of cost of dewatering and desilting. For the perticular reach of canal where dewatering and desilting are contemplated 2 percent of basic rate shall be added to all items in the estimate for that reach towards dewatering and desilting during execution of work. 4
