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

Balance 69 kms `: 372.60

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.

SECTION: DAM AND ALLIED WORKS. YEAR : 2014-15 ITEM No: WRD:2.1

ITEM: Excavation for foundation in all kinds of soil including boulders upto 0.60 m dia.( 0.113 cum )

for dam, spillway, intake structure, surface power house and other appurtenant works and

placing the excavated soil neatly in specified dump area or disposing off the same as directed

including cost of all materials, machinery, labour etc., complete with lead upto 1 km and

all lifts.

DATA:Capacity of shovel bucket : 0.85 cum

Capacity of shovel bucket under heaped condition : 1.00 cum

Capacity of topper : 5.00 cum

Lead for disposal of excavated soil : 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 : 20 sec

1. Quantity of excavation :

In-situ qty / bucket for 20 % bulkage on unloading ( 1 / 1.20 ) : 0.83 cum

In-situ quantity per load for 5 cum soil ( 5 / 1.20 ) : 4.17 cum

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

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 : 11.50 min

No.of tippers to match corrected cycle time of shovel (11.5 / 2.0) : 5.75 Nos

Output of tipper / hr with 50 min working / hr ( 50 x 4.17 / 11.50 ) : 18.13 cum

Output for 5.75 tippers per day ( 5.75 x 18.13 x 8 ) say : 834 cum

Further, consider about 95 percent excavation by deploying shovel and 5 percent excavation by

manual labour mainly for trimming the bed / sides to final profile.

Daily quantity of excavation in soil ( 834 / 0.95 ) say : 880 cum

Consider 880 cum for rate analysis.

2. Requirement of materials :

No materials involved in the work.

3. Requirement of machinery :

Deploy 0.85 cum capacity shovel for 8 hours for digging and loading 834 cum.

Deploy 6 tippers of 5 cum capacity for 8 hours for disposal of 834 cum.

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.


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

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








No. of rows of holes for 7 m width @ 1 m burden ( 7 / 1 ) : 7 rows

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. Considering the laying time for pillars and wall panels at twice

the production time the average cycle time will be about 1.5 times the production cycle time.

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.

Average cycle time for laying concrete ( 4.50 x 1.8 ) : 8.10 min

No. of mixes per day with 50 min / hr working ( 50 x 8 / 8.1 ) say : 50 mixes

Output of CC for 50 mixes ( 50 x 50 / 330 ) : 7.6 cum

As the computed daily output of 7.60 cum also matches with the one span parapet quantity of

7.60 cum consider the daily output at 7.60 cum for rate analysis.

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

Digging soil in dump area will be relatively faster compared to digging in borrow area in view of

loose condition of soil. However, the loading cycle time remains same whether the soil is from

borrow area or from dump area. Therefore, for use of dump area soil for embankment a combined

digging and loading cycle time at 65 percent of borrow area may be considered.
