FOR THE YEAR :

1. All notes under ' General Notes on Schedule of Rates ' and ' Notes on Lead, Lift, Loading andun-loading Charges ' are applicable to ' Dam and Allied Works ' also to the extent they arerelevant.

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 guidelines 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 concretesurface.

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 basicrate. Additional lead charges for cement and steel shall be worked out by deducting initial lead of 1km from the total lead and loading and unloading charges shall be allowed in view of rehandlingof cement and steel from site store / fabrication yard to work place.Example :Total lead for cement : 100 kmLess Rehandling lead included in basic rate : 1 kmNet lead for working out additional lead charges : 99 kmAdditional lead charges : First 5 kms Rs: 39.40 Next 25 kms Rs: 77.50 Balance 69 kms Rs: 200.10 Loading & unloading charges Rs: 55.40 Total additional lead charges / tonne Rs: 372.40Additional lead charges for sand, coarse aggregate, stones and stone chips shall be workedout for total lead involved and 1 km lead charges included in basic rate shall be deducted fromtotal lead charges.

Note : i ) 1 m width of excavation along the face to be dressed shall be treated as excavation by linedrilling and smooth blasting.ii ) The rate under this item shall be paid only on ascertaining that the surface requiring dressinghas 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 / sluicestructures 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 ofexcavation. 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 smoothblasting and requirement of neat excavated surface for two sides.Depth of drilling per hole 0.90 mEffective depth of pull per hole 0.80 mQuantity of excavation ( 20 + 30 ) x 1 x 0.8 40 cumConsider spacing of peripheral holes at 10 times diameter of hole.Spacing of peripheral holes : 0.33 mNumber of boundary holes on two sides ( 20 + 30 ) / 0.33 : 152 NosDepth of drilling @ 0.9 m per hole ( 152 x 0.9 ) : 136.8 mAdd for secondary blasting for 5 % quantity @ 0.6 m / cum : 1.2 m

DATA: Generally, batching plant mixer platform will be at a convenient height above general gruondlevel to facilitate loading of mixed concrete to trolley / tipper mounted concrete buckets. Assuch, the material / weighing hoppers and aggregate storage bins will be sufficiently aboveground level requiring some mechanical arrangement for conveyance of aggregates fromaggregate stock piles to batching plant material bins. Further, for mass concrete works

generally the specifications provide for cooling of aggregates by spraying / circulation of normal/ chilled water in addition to use of ice to maintain the placement temperature of concrete atspecified level. In view of multiple handling of aggregates from stock piles to cooling bins and from there to batching plant material bins belt conveyor system is generally used for handlingaggregates.
