un-loading Charges ' are applicable to ' Dam and Allied 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 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 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

Loading & unloading charges `: 163.00
Total additional lead charges / tonne `: 760.80
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 : For sand :
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 `: 89.30
Lead charges for next 10 km `: 92.00
Total lead charges for 15 km /cum `: 181.30
Less 1 km initial lead charges / cum `: -49.50
Net additional lead charges / cum `: 131.80
No 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 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.

Number of buckets per load ( 4.17 / 0.83 ) say : 5 buckets
Ideal cycle time for loading 5 buckets ( 5 x 20 / 60 ) : 1.67 min
The ideal cycle time for shovel requires spotting of a tipper within 1.67 minutes near the
shovel. However, in practice for dam or canal excavation the space available may not permit
positioning of tippers on either side of the shovel. Generally one tipper has to move after
loading to position the next tipper for loading. Assuming one extra cycle for shovel, the
corrected cycle time for the shovel will be : ( 6 x 20 / 60 ) : 2.00 min
Round trip cycle time for tipper :
Cycle time of shovel for digging and loading : 2.00 min
Time for 1km haulage under load ( 60 / 15 ) : 4.00 min

DAM ALLIED WORKS
SECTION: DAM AND ALLIED WORKS. YEAR : 2014-15 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 one
or combination of line drilling/pre-splitting/smooth blasting techniques 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 and
skin material to expose fresh rock for seating of structure. Therefore, the depth of hole is limited
to 0.90 m for rate analysis.
For intake structure / surface power house the depth excavation will be more and holes uto 5 m
may 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 effective
blasting 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 is
mainly 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 diameter
of hole and spacing of holes is considered at 1.20 times burden.
Burden for 32 mm dia jack hammer holes say : 1.00 m
Spacing of holes @ 1.20 times burden : 1.20 m
Grid spacing of holes in m : 1.00 x 1.20 m
Quantity of excavation per blast ( 17 x 7 x 0.8 ) : 95 cum
Further, consider loading of about 95 percent excavated rock by shovel and 5 percent excavated
rock 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 cum
Consider 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 m
Spacing of holes @ 1.20 times burden : 1.20 m
Grid spacing of holes in m : 1.00 x 1.20 m
No. of rows of holes for 7 m width @ 1 m burden ( 7 / 1 ) : 7 rows
No. 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 Nos
For blasting a combination of 20 % high strength ANFO booster and 80 % ANFO mixed with
diesel is proposed.
Drilling and Blasting pattern :
Pattern of holes : Staggered
14
DAM ALLIED WORKS
Hole initiation : Bottom
Initiation system : Electric detonators
Initiation pattern : Straight line all rows
secondary blasting may be necessary after main blasting to break any large rock fragments.
Quantity for secondary blasting @ 5 % ( 95 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 m
Depth of drilling for secondary holes @ 0.6 m / cum ( 5 x 0.6 ) say : 3.00 m
Total depth of drilling for main and secondary blasting : 88.50 m
Consider 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 / hour
Rate of drilling in hard rock with 50 min / hr working ( 6 x 50 / 60 ) : 5 m / hour
Time required for drilling with 4 jack hammers ( 88.5 / 4 / 5 ) say : 4.5 hours
3. Disposal of excavated rock:
Capacity of shovel bucket : 0.85 cum
Capacity of shovel bucket under heaped condition : 1.00 cum
Capacity of tipper : 5.00 cum
Lead for disposal of excavated hard rock : Upto 1 km
Speed for loaded tipper under haul road condition : 15 km / hr
Speed for empty tipper under haul road condition : 20 km / hr
Turning and unloading time : 2.00 min
Shovel digging and loading cycle per bucket : 45 sec
In-situ quantity / bucket for 40 % bulkage on unloading ( 1 / 1.40 ) : 0.71 cum
In-situ quantity per load for 5 cum of hard rock ( 5 / 1.40 ) : 3.57 cum
Number of buckets per load ( 3.57 / 0.71 ) say : 5 buckets
Ideal cycle time for loading 5 buckets ( 5 x 45 / 60 ) : 3.75 min
The ideal cycle time for shovel requires spotting of a tipper within 3.75 minutes near the
shovel. However, in practice for dam or canal excavation, the space available may not permit
positioning of tippers on either side of the shovel. Generally one tipper has to move after
loading to position the next tipper for loading. Assuming one extra cycle for shovel, the
corrected cycle time for the shovel will be : : 4.50 min
Round trip cycle time for tipper:
Cycle time of shovel for digging & loading : 4.50 min
Time for 1km haulage under load ( 60 / 15 ) : 4.00 min
Time for turning and un-loading : 2.00 min
Time for 1 km return trip ( 60 / 20 ) : 3.00 min
Time for turning and spotting : 0.50 min
Total : 14.00 min
No.of tippers to match corrected cycle time of shovel (14.0 / 4.5) : 3.11 Nos
Output of tipper / hr with 50 min working / hr ( 50 x 3.57 / 14.00 ) : 12.75 cum
Time for disposal of 95 cum muck by 3 tippers ( 95 / 12.75 / 3 ) say : 2.5 hours
4. Requirement of materials:
Jack hammer drill rods for drilling : 88.5 m drilling
Air hose for supplying air to 4 jack hammers ( 4.5 x 4 ) : 18 hours
Quantity of explosive for 100 cum @ 0.5 kg / cum ( 100 x 0.5 ) : 50 kg
High strength ANFO booster @ 20 % ( 50 x 0.20 ) : 10 kg
ANFO @ 80 % ( 50 x 0.8 ) : 40 kg
Diesel @ 180 ml / kg ANFO ( 40 x 0.18 ) : 7 ltr
Explosive at 0.20 kg / cum for 5% secondary blast ( 95x0.05x0.2 ) : 1 kg
Ele.detonators at 1 per hole for 95 main blast holes ( 95 x 1 ) : 95 Nos.
15
DAM ALLIED WORKS
Ord.detonators @ 1 per hole for 9 secondary holes ( 9 x 1 ) : 5 Nos.
Detonating fuse coil : 120 Rm
5. Requirement of machinery :

II. Consider drilling by Wagon drills 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.
Generally Waggon drill is used for excavation in hard rock where the depth of excavation is more.
Consider half width of the block for drilling and blasting at a time.
For good fragmentation to facilitate easy loading by 0.85 cum capacity shovel the bench height
to burden ratio shall be more than 3.
Generally, the length of excavation in hard rock for use of waggon drill at a time will be limited to
6 to 7 m for effective blasting to minimise digging and loading cycle of shovel.
Consider 6 m length and 15 m width of excavation per blast.
Depth of drilling per hole including depth of sub-drilling : 6.00 m
Effective depth of hole for jack hammer drilling ( 6.0 - 0.6 ) : 5.40 m
The burden ( distance of hole from free face of excavation ) is considered at 20 times diameter
of hole and spacing of holes is considered at 1.25 times burden.
Burden for 100 mm dia waggon drill holes : 2.00 m

DAM ALLIED WORKS
SECTION: DAM AND ALLIED WORKS. YEAR : 2014-15 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 and
skin material to expose fresh rock for seating of structure. Therefore, the depth of hole is limited
to 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-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:
- 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.

Construction of parapet involves laying of concrete in three stages namely ( i ) kerb, ( ii ) pillars
and wall panels and ( iii ) coping. While concrete laying cycle can be matched with production
cycle for kerb and coping, the laying cycle will be very slow for pillars and wall panels in view of
thin sections with reinforcement. For ornamental parapet the laying cycle time will be more than
solid parapet in view of openings in wall panels. Considering the laying cycle time for pillars and
wall panels with openings 3 times the production cycle time the average cycle time will be about
1.8 times the production cycle time.

DAM ALLIED WORKS
Hourly output of batching plant ( based on data in item-13 ) : 30 cum
Proposed temperature of concrete at placing point : between 18 & 21 deg C
Av. temperature of concrete at placing point considered for rate analysis : 19.5 deg C
Probable gain in temperature during conveying CC from BP to block : 2 to 3 deg C
Av gain in temperature during conveying CC considered for rate analysis : 2.5 deg C
Required temperature of concrete at batching plant ( 19.5 - 2.5 ) : 17 deg C
Precooling of aggregate is not considered. However, as coarse aggregate stocked in open area
is exposed to sunlight during day time spraying normal water over coarse aggregate heaps is
considered to keep the aggregate temperature at minimum possible level.
Use of chilled water and flaked ice is considered for mixing concrete.
Material parameters considered / assumed for determining the quantity of ice flakes:
Weight of Cement ( Wc ) : 210 kg
Temperature of cement in silo ( Tc ) : 45 deg C
Specific heat of cement ( Cc ) : 0.25
Weight of Coarse aggregate ( Wa ) : 1490 kg
Temperature of wet CA in BP aggregate bins ( Ta ) : 25 deg C
Specific heat of coarse aggregate ( Ca ) : 0.22
Free water in wet CA @ 2% ( 0.02 x 1490 ) ( Wam ) : 29.80 kg
Weight of Fine aggregate ( Ws ) : 575 kg
Temperature of FA in BP fine aggregate bin ( Ts ) : 27 deg C
Specific heat of fine aggregate ( Cs ) : 0.22
Free moisture in wet FA @ 1% ( 0.01 x 575 ) ( Wsm ) : 5.75 kg
Weight of Water including free moisture and ice flakes ( Ww ) : 126 kg
Temperature of chilled water in BP mixing water tank ( Tw ) : 5 deg C
Specific heat of normal / chilled water ( Cw ) : 1.00
Weight of ice flakes in kg ( Wi ) : to be determined
Temperature of ice flakes in ice elevator ( Ti ) : - 5 deg C
Specific heat of ice flakes ( Ci ) : 0.50
Latent heat in kilo calories ( kcal ) ( L ) : 80 kcal
Required temperature of concrete at batching plant ( T ) : 17 deg C
1.a Heat dissipated by Cement / CA / FA / free water in CA & FA :
Heat dissipated by Cement in kcal Wc x Cc ( Tc - T )
210 x 0.25 ( 45 - 17 ) say: 1470.00
Heat dissipated by Coarse aggregate in kcal Wa x Ca ( Ta - T )
1490 x 0.22 ( 25 - 17 ) say: 2625.00
Heat dissipated by Fine aggregate in kcal Ws x Cs ( Ts - T )
575 x 0.22 ( 27 - 17 ) say: 1265.00
Heat dissipated by free water in CA in kcal Wam x Cw ( Ta - T )
29.80 x 1.00 ( 25 - 17 ) say: 240.00
Heat dissipated by moisture in FA in kcal Wsm x Cw ( Ts - T )
5.75 x 1.00 ( 27 - 17 ) say: 60.00
Total heat dissipated in kcal = 1470.00 + 2625.00 + 1265.00 + 240.00 + 60.00
= 5660.00 kcal
1.b Heat absorbed by Chilled water / Ice flakes :
Quantity of chilled mixing water = ( Ww - Wam - Wsm - Wi )
Heat absorbed by chilled mixing water in kcal = ( Ww-Wam-Wsm-Wi ) Cw ( T -Tw )
( 126 - 29.8 - 5.75 - Wi ) x 1.00 x ( 17 - 5 ) : 1085 - 12Wi
Heat absorbed by ice flakes in kcal = Wi x ( Cw x T - Ci x Ti + L )
= Wi x ( 1 x 17 - 0.5 x -5 + 80 ) : 99.5Wi kcal
85
DAM ALLIED WORKS
Total heat absorbed by chilled water and ice flakes in kcal = 1085.00 - 12Wi + 99.5Wi
= ( 1085.00 + 87.5Wi )
1.c Quantity of ice required based on heat balance equation :
Total heat absorbed by chilled water and ice flakes = Total heat dissipated by other ingradients
1085.00 + 87.5Wi = 5660.00
87.5 Wi = 5660.00 - 1085.00
Weight of ice flake / cum of concrete ( 5660.00 - 1085.00 ) / 87.5 say : 53 kg
Quantity of ice required / day for 500 cum concrete ( 53 x 500 ) / 1000 : 26.5 tonnes
Consider pre-cooling of 500 cum concrete for rate analysis.
2. Requirement of materials:

DAM ALLIED WORKS
However, in practice, the space available on either side of the shovel may not permit free
movement of the tippers quickly. Some times one loaded tipper has to move after loading to
position next tipper for loading. Assuming one extra cycle for shovel the corrected cycle time
for the shovel will be 2.00 minutes.
Round trip cycle time for tipper:
Cycle time of shovel for digging & loading : 2.00 minutes
Time for 1km haulage under load ( 60 / 20 ) : 3.00 minutes
Time for turning and un-loading : 2.00 minutes
Time for 1 km return trip ( 60 / 25 ) : 2.40 minutes

Output for 5 tippers per day ( 5 x 21.70 x 8 ) say : 870 cum
The in-situ dry density of soil in borrow area will be generally less than dry density of compacted
embankment. Therefore, the rolled embankment quantity will be slightly less than the borrow
area in-situ quantity. The extent of shrinkage in quantity depends on the degree of compaction.
For 95 % density control of embankment a shrinkage factor of 5 % may be assumed.
Quantity of embankment considering 5 %shrinkage ( 870 x 0.95 ) say : 825 cum
Qty of soil for computing royalty charges @ 1.6 t / cum ( 825x1.6 ) : 1320 tonnes
Consider 825 cum rolled hearting embankment for rate analysis.
2. Stripping of borrow area :
Generally borrow area is stripped once in a week for 6 days requirement of soil.
Area to be stripped assuming 2.0 m depth of cut ( 870 x 6 / 2.0 ) : 2610 sqm
Depth of stripping : 0.25 m
Qty of stripping considering 5 % extra area ( 2610 x 1.05 x 0.25 ) : 685 cum
Output of dozer per hr with 50 min / hr working for stripping : 100 cum
Time required for stripping 685 cum ( 685 / 100 ) : 6.85 hours
Consider 8 hours including time for levelling stripped siol / shifting time.

Deploy dozer for 1.3 hours for stripping borrow area for 825 cum embankment work.
3. Collection of soil for embankment:
Deploy one 0.85 cum capacity shovel for 8 hours for digging and loading soil.
Deploy 5 tippers of 5.00 cum capacity for 8 hours to convey soil to embankment area.
4. Spreading soil in 250 to 300 mm layer:
Quantity of loose soil to be spread ( 870 x 1.20 ) : 1044 cum
Output of dozer for levelling per hour : 250 cum
Time required for levelling 1044 cum ( 1044 / 250 ) say : 4.20 hours
Deploy dozer for 4.2 hours for spreading and levelling soil for 825 cum embankment work.
5. Watering;
Generally soil in borrow area will be in moist condition. In the beginning of the season no
watering may be necessary and in summer months about 8 to 10 percent watering may be
needed to maintain the soil moisture within OMC plus or minus 3 percent limit. Assuming
seasonal average of 4 to 5 percent watering by weight, daily requirement of water for 825 cum
of embankment will be about 8 tanker loads of 8000 ltrs each.
Deploy 8000 ltr capacity water tanker for 8 hours daily for watering before rolling.
Deploy 5 hp pump for 4 hours.

Ideal cycle time for loading 5 buckets ( 5 x 16 / 60 ) say : 1.33 min
The ideal cycle time for shovel requires spotting of tipper within 1.33 minutes near the shovel.
However, in practice, the space available on either side of the shovel may not permit free

The output worked out above is the insitu quantity in dump area with 10 % bulkage factor.
The in-situ dry density of soil in borrow area will be generally less than dry density of compacted
embankment. Therefore, the rolled embankment quantity will be slightly less than the borrow
area in-situ quantity. The extent of shrinkage in quantity depends on the degree of compaction
of embankment. For 95 % density control of embankment a shrinkage factor of 5 % is assumed
for use of borrow area soil.
Further, as the insitu density of soil in dump area will be less compared to natural ground due
to bulkage of soil in dump area, for applying the shrinkage foctor the insitu dump area quantity
may be converted to equivalent insitu borrow area quantity by applying the bulkage factor.

sorting out, breaking clods, levelling, sectioning edges / sides, watering, compacting to density
control of not less than 95 percent using pnuematic tampers / vibrating earth rammers etc.,
complete with lead upto 1 km and all lifts.
DATA:For woks like back filling trial pits in embankment area and around key blocks where it may not
be possible to use dozer and roller for spreading and compaction of soil. Similarly, dozer and
roller are, generally, not permitted for spreading and rolling soil adjacent to masonry / concrete
structures to avoid possible damage to structures. In such locations, spreading soil by manual
labour and compaction by pnuematic tamper or vibrating plate compactor is adopted.
For purpose of rate analysis manual spreading and compaction by vibrating plate compactor is
considered.
