5 NOTES ON SCHEDULE OF RATES DAM 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 ' Dam 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 ' Notes on Royalty charges ' 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. Unless otherwise specified the basic rates are inclusive of standard finish required for concrete surface. 7. The basic rates for concrete items include cost of cleaning / green cutting top surface of previous lift of concrete 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. 8. For concrete, masonry and reinforcement items initial lead of 1km is considered in the basic rate. Additional lead charges for cement and steel shall be worked out by deducting initial lead of 1 km from the total lead and loading and unloading charges shall be allowed in view of rehandling of cement and steel from site store / fabrication yard to work place. Example : Total lead for cement : 100 km Less Rehandling lead included in basic rate : 1 km Net lead for working out additional lead charges : 99 km Additional lead charges : First 5 kms Rs: Next 25 kms Rs: Balance 69 kms Rs: Loading & unloading charges Rs: Total additional lead charges / tonne Rs: Additional lead charges for sand, coarse aggregate, stones and stone chips shall be worked out for total lead involved and 1 km lead charges included in basic rate shall be deducted from total lead charges. No loading and unloading charges shall be allowed since no rehandling lead is involved for these materials. Example : Total lead for sand from approved sand quarry : 15 km Initial lead included in the basic rate in the SR : 1 km Additional lead charges : Lead charges for 5 km Rs: Lead charges for next 10 km Rs: Total lead charges for 15 km /cum Rs: Less 1 km initial lead charges / cum Rs: Rs: Net additional lead charges / cum Rs: No loading and un-loading charges shall be added. 4

6 9. 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 / cum Rs: 5.80 No loading and un-loading charges shall be added. 10. 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 incidentals. The actual cement content may vary based on trial mix studies. Suitable clause shall be included in tender for regulating payment for any upword or downword variation in cement. 11. 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. 12. The basic rates are exclusive of cost of dewatering and desilting. Wherever, dewatering and desilting are contemplated 2 percent of basic rate shall be added to all items in the estimate towards dewatering and desilting during execution of work. 13. The basic rates are exclusive of cost of site clearing and river diversion arrangements such as coffer dams, bunds, diversion channels etc. Separate sub-estimates shall be prepared for all types coffer dams, bunds, diversion channels etc., and based on such sub-estimates lump-sum provision shall be included in the main estimate for the work. 5

YEAR: ITEM No: 4.c ITEM: Excavation for foundation in hard rock of all toughness including boulders above 1.2 m dia. by line drilling and smooth blasting and controlling fly-rock by muffling arrangements for dam, spillway, intake structure and other appurtenant structures etc., including dressing 17

19 sides and bed to required level / profile, placing and levelling the excavated rock neatly in dump area or other place as directed etc., complete with lead upto 1 km and all lifts. Note : i ) 1 m width of excavation along the face to be dressed shall be treated as excavation by line drilling and smooth blasting. ii ) The rate under this item shall be paid only on ascertaining that the surface requiring dressing has come off neatly as per specifications or atleast 50 percent of smooth blast holes are visible for inspection and are spaced at specified interval. iii ) In case, where the above criteria is not fulfilled payment shall be restricted to the rate provided for excavation by normal or controlled blasting as the case may be.. DATA: Excavation in hard rock by line drilling and smooth blasting with arrangements for control of fly-rock is generally adopted where there are structures very close to dam site or for foundation excavation for dam blocks in flood gap portion or for excavation of power house pit / sluice structures near toe of dam blocks. Work requires: - drilling additional holes along the boundary of excavation area and smooth blasting to obtain neat excavated profile minimising over-cuts. - Limiting the depth of holes and use of delay detonators to minimise explosive energy to reduce ground vibrations. - covering blasting area with chain link mesh or waste conveyor belts or waste tyres and sand bags to prevent flying of rock fragments during blasting. Consider drilling by Jack hammers and mucking by deploying Shovel and Dumpers. Drilling and Blasting : Consider 20 m x 30 m area for excavation. For obtaining neat side face blast holes are to be drilled at closer interval along the boundary of excavation. Only alternative holes are to be charged and blasted along with main blast. Electric delay detonators are to be used to control ground vibrations. Consider 1 m width of excavation along the boundary as area requiring line drilling and smooth blasting and requirement of neat excavated surface for two sides. Depth of drilling per hole 0.90 m Effective depth of pull per hole 0.80 m Quantity of excavation ( ) x 1 x cum Consider spacing of peripheral holes at 10 times diameter of hole. Spacing of peripheral holes : 0.33 m Number of boundary holes on two sides ( ) / 0.33 : 152 Nos Depth of 0.9 m per hole ( 152 x 0.9 ) : m Add for secondary blasting for 5 % 0.6 m / cum : 1.2 m Total : m Rate of drilling in hard rock by jack hammer 8 m / hr Drilling output for use of 4 jack hammers / hour : m Time for drilling m per hour : 4.3 hours Deploy 2 air compressors of 8.5 cmm capacity and 4 jack hammers for 5.5 hours for drilling with 50 min per hour working.
