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. 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 concretesurface.
4. 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.
5. 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 `: 74.80 Next 25 kms `: 140.00 Balance 69 kms `: 365.70 Loading & unloading charges `: 140.80 Total additional lead charges / tonne `: 721.30Additional 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. No loading and unloading charges shall be allowed since no rehandling leadis involved for these materials.Example : For sand :Total lead for sand from approved sand quarry : 15 kmInitial lead included in the basic rate in the SR : 1 kmAdditional lead charges : Lead charges for 5 km `: 85.10 Lead charges for next 10 km `: 90.00 Total lead charges for 15 km /cum `: 175.10 Less 1 km initial lead charges / cum `: -46.00 Net additional lead charges / cum `: 129.10No loading and un-loading charges shall be added.
6. For earth / rockfill embankment works 1 km initial lead is considered in the basic rates. As nostoring / stacking and re-handling of materials is involved for these works lead charges foradditional lead shall be worked out for total lead including initial lead of 1 km and then thecost of first km lead shall be deducted. No loading and un-loading charges shall be added asthe additional lead does not involve re-handling of materials.

SECTION: DAM AND ALLIED WORKS. YEAR : 2013-14 ITEM No: WRD:2.4.1
ITEM: Excavation for foundation in hard rock of all toughness by blasting including boulders above 0.6 m dia ( 0.113 cum ) for dam, spillway, intake structure, surface power house and other appurtenant structures minimising damage to rock beyond excavation line by adopting any oneor combination of line drilling/pre-splitting/smooth blasting techniques and placing the excavatedrock neatly in specified dump area as directed including cost of all materials, machinery, labour etc.,complete with lead upto 1 km and all lifts.
DATA:Generally for dam works excavation in hard rock is for limited depth to remove top jointed andskin material to expose fresh rock for seating of structure. Therefore, the depth of hole is limitedto 0.90 m for rate analysis.For intake structure / surface power house the depth excavation will be more and holes uto 5 mmay be considered. Jack hammer drilling for shallow holes and waggon drill holes for deeper holes is considered.
I. Consider drilling by Jack hammers and mucking by deploying Shovel and tippers.1. Quantity of excavation :
For a dam of medium height the width of foundation will be about 30 to 35 m.Consider half width of the block for drilling and blasting at a time.Generally, the length of excavation in hard rock at a time will be limited to 6 to 7 rows for effectiveblasting to minimise digging and loading cycle of shovel.Consider 7 m length and 17 m width of excavation per blast. As excavation for dam foundation ismainly to expose fresh hard rock the depth of hole is assumed at 0.90 m.Depth of drilling per hole : 0.90 m Effective depth of hole for jack hammer drilling ( 0.9 - 0.1 ) : 0.80 m The burden ( distance of hole from free face of excavation ) is considered at 30 times diameterof hole and spacing of holes is considered at 1.20 times burden.Burden for 32 mm dia jack hammer holes say : 1.00 mSpacing of holes @ 1.20 times burden : 1.20 mGrid spacing of holes in m : 1.00 x 1.20 mQuantity of excavation per blast ( 17 x 7 x 0.8 ) : 95 cumFurther, consider loading of about 95 percent excavated rock by shovel and 5 percent excavatedrock mainly consisting of trimmed bed material and blasted boulders etc., by manual labour.Daily quantity of excavation in hard rock ( 95 / 0.95 ) say : 100 cumConsider 100 cum for rate analysis.
2. Drilling and Blasting :Depth of drilling per hole : 0.90 m Effective depth of hole for jack hammer drilling ( 0.9 - 0.1 ) : 0.80 m Burden for 32 mm dia jack hammer holes say : 1.00 mSpacing of holes @ 1.20 times burden : 1.20 mGrid spacing of holes in m : 1.00 x 1.20 mNo. of rows of holes for 7 m width @ 1 m burden ( 7 / 1 ) : 7 rowsNo. of holes in 4 rows for 17 m width @ 1.2 m C/C ( 4 x 17 / 1.2 ) : 56 Nos.No. of holes in 3 rows for 15.8 m @ 1.2 m C/C ( 3 x 15.8 / 1.2 ) : 39 Nos.Total number of holes in 17 x 7 m area : 95 NosFor blasting a combination of 20 % high strength ANFO booster and 80 % ANFO mixed withdiesel is proposed.Drilling and Blasting pattern :Pattern of holes : Staggered

However, in practice for dam or canal excavation, the space available may not permitpositioning of tippers on either side of the shovel. Generally one tipper has to move afterloading to position the next tipper for loading. Assuming one extra cycle for shovel, thecorrected cycle time for the shovel will be : : 4.50 minRound trip cycle time for tipper:Cycle time of shovel for digging & loading : 4.50 minTime for 1km haulage under load ( 60 / 15 ) : 4.00 minTime for turning and un-loading : 2.00 minTime for 1 km return trip ( 60 / 20 ) : 3.00 minTime for turning and spotting : 0.50 min

SECTION: DAM AND ALLIED WORKS. YEAR : 2013-14 ITEM No: WRD:2.4.2
ITEM: Excavation for foundation in hard rock of all toughness including boulders above 0.6 m diameter ( 0.113 cum ) for dam, spillway, intake structure, surface power house and other appurtenant structures by approved controlled blasting methods including control of vibration by use of delay detonators and control of fly-rock by muffling arrangements etc., and placing the excavated rock neatly in specified dump area as directed including cost of all materials, machinery, labour etc., complete with lead upto 1 km and all lifts.
DATA:Generally for dam works excavation in hard rock is for limited depth to remove top jointed andskin material to expose fresh rock for seating of structure. Therefore, the depth of hole is limitedto 0.90 m for rate analysis.Consider drilling by Jack hammers and mucking by deploying Shovel and tippers.Excavation in hard rock by controlled blasting method with arrangements for control of fly-rockis generally adopted where there are structures very close to dam site or for foundationexcavation for dam blocks in flood gap portion or for excavation of power house pit / sluicestructures near toe of dam blocks.Work requires: - 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.Capacity of shovel bucket : 0.85 cumCapacity of shovel bucket under heaped condition : 1.00 cumCapacity of tipper : 5.00 cumLead for disposal of excavated hard rock : Upto 1 kmSpeed for loaded tipper under haul road condition : 15 km / hrSpeed for empty tipper under haul road condition : 20 km / hrTurning and unloading time : 2.00 minShovel digging and loading cycle per bucket : 45 sec
1. Quantity of excavation :In-situ quantity / bucket for 40 % bulkage on unloading ( 1 / 1.40 ) : 0.71 cumIn-situ quantity per load for 5 cum of hard rock ( 5 / 1.40 ) : 3.57 cumNumber of buckets per load ( 3.57 / 0.71 ) say : 5 bucketsIdeal cycle time for loading 5 buckets ( 5 x 45 / 60 ) : 3.75 minThe ideal cycle time for shovel requires spotting of a tipper within 3.75 minutes near theshovel. However, in practice for dam or canal excavation, the space available may not permitpositioning of tippers on either side of the shovel. Generally one tipper has to move afterloading to position the next tipper for loading. Assuming one extra cycle for shovel, thecorrected cycle time for the shovel will be : : 4.50 minRound trip cycle time for tipper:Cycle time of shovel for digging & loading : 4.50 minTime for 1km haulage under load ( 60 / 15 ) : 4.00 minTime for turning and un-loading : 2.00 minTime for 1 km return trip ( 60 / 20 ) : 3.00 minTime for turning and spotting : 0.50 min
Total : 14.00 minNo.of tippers to match corrected cycle time of shovel (14.0 / 4.5) : 3.11 NosOutput of tipper / hr with 50 min working / hr ( 50 x 3.57 / 14.00 ) : 12.75 cum Time for disposal of 91 cum muck by 3 tippers ( 91 / 12.75 / 3 ) say : 2.5 hours

Further, consider loading of about 95 percent excavated rock by shovel and 5 percent excavatedrock mainly consisting of trimmed bed material and blasted boulders etc., by manual labour.Daily quantity of excavation in hard rock ( 91 / 0.95 ) say : 96 cumConsider 96 cum for rate analysis.
2. Drilling and Blasting :Depth of drilling per hole : 0.90 m Effective depth of hole for jack hammer drilling ( 0.9 - 0.1 ) : 0.80 m The burden ( distance of hole from free face of excavation ) is considered at 30 times diameterof hole and spacing of holes is considered at 1.20 times burden.Burden for 32 mm dia jack hammer holes say : 1.00 mSpacing of holes @ 1.20 times burden : 1.20 mGrid spacing of holes in m : 1.00 x 1.20 mFor a dam of medium height the width of foundation will be about 30 to 35 m.Consider half width of the block for drilling and blasting at a time.No. of holes in a row for 17 m width @ 1.2 m C/C ( 17 / 1.2 ) : 14 Nos.Generally, the length of excavation in hard rock at a time will be limited to 6 to 7 rows for effectiveblasting to minimise digging and loading cycle of shovel.Consider 7 m length of excavation per blast.No. of rows of holes for 7 m width @ 1 m burden ( 7 / 1 ) : 7 rowsDrilling and Blasting pattern :Pattern of holes : StaggeredHole initiation : BottomInitiation system : Short delay detonatorsDelay system : 25 ms intervalInitiation pattern : Straight line row by rowNos. of main blast holes for 7 rows ( 4 x 14 + 3 x 13 ) : 95 Nos.Area of excavation for 95 holes ( 95 x 1.2 x 1.0 ) : 114 sqmQuantity of excavation for 0.8 effective depth ( 114 x 0.8 ) say : 91 cumSecondary blasting may be necessary after main blasting to break any large rock fragments.Quantity for secondary blasting @ 5 % ( 91 x 0.05 ) : 5 cum.Nos. of secondary blast holes @ 1 per cum for 9 cum ( 5 x 1 ) : 5 Nos.Depth of drilling for main blast ( 95 x 0.9 ) : 85.50 mDepth of drilling for secondary holes @ 0.6 m / cum ( 5 x 0.6 ) say : 3.00 mTotal depth of drilling for main and secondary blasting : 88.50 mConsider 2 Nos. 8.5 cmm air compressors and 4 jack hammers for drilling.Rated rate of drilling in hard rock by jack hammer : 6 m / hourRate of drilling in hard rock with 50 min / hr working ( 6 x 50 / 60 ) : 5 m / hourTime required for drilling with 4 jack hammers ( 88.5 / 4 / 5 ) say : 4.5 hours
3. Muffling arrangements:For controlling flying of rock fragments during blasting consider covering the blasting area with20 guage 50 x 50 mm opening chain link mesh and sand bags.Consider spreading chain link mesh 0.5 m beyond excavation area.Area of chain link mesh ( 17 +1 ) x ( 7 + 0.5 ) : 135 sqmAdd for overlaps @ 10 % say : 15 sqm
