FOR THE YEAR : 2014-15

1. All notes under ' General Notes on Schedule of Rates ' and Notes on Lead, Lift, Loading and

un-loading Charges are applicable to Canal and Allied Works also to the extent they are

relevant.

2. Unless otherwise specified the basic rates are inclusive of all lifts.

3. 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 `: 59.90

Less Lead charges for 1 km `: -49.50

Additional lead charges `: 10.40

No loading and un-loading charges shall be added.

4. 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 any

incidentals. The actual cement content may vary based on trial mix studies. A suitable clause

shall be included in the tender for regulating payment for any upward or downward variation in

cement content.

5. A weightage of 25 percent over the rates in the SR is permissible for all items of works involved

in the modernization of canals and which are to be carried out during the canal closure period

of about 3 - 4 months and less. In the estimates for modernization, the items of work shall

appear based on the rate in SR without the permissible weightage. Below the respective items,

the weightage permissible for the item is to be included. Further, the payment of weighatage

is permissible only when the contractor completes a minimum of 90 percent of the work

entrusted in a single closure period. Failing which the contractor foregoes the advantage of

weightage. Payment of RA bills shall be made at rates excluding the weightage. It is only in

the last RA bill / final bill, payment for weightage is to be released subject to above condition.

6. 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.

SECTION: CANAL AND ALLIED WORKS. YEAR : 2014-15 ITEM No: WRD: 3.6.1

ITEM: Excavation in hard rock of all toughness by blasting including boulders above 0.6 m dia.

( 0.113 cum ) for canals, cut-off trench of embankment, filter / catch water drains etc.,

minimising damage to side slopes of canal in water prism area by adopting any one or

combination of line drilling /pre-splitting /smooth blasting techniques and placing the excavated

rock neatly in approved dump area as directed including cost of all materials,machinery, labour,

levelling bed etc., complete with lead upto 1 km and depth of cut upto 18 m.

DATA:Excavation for canal in hard rock can be by using jack hammers or by using waggon drills or

by combination of both depending on the depth of cut, width of canal and side slope. In case of

waggon drill the rate of drilling will be faster and yeild per hole will be more due to wider spacing

of holes. For jack hammer drill the yeild per hole will be less due to closer spacing of holes.

As both the systems have advantages as well as disadvantages it is proposed to work out rates

using both the systems and include average rate in the Schedule of Rates.

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 ( 605 x 0.95 ) : 575 cum

Qty of soil for computing royalty charges @ 1.6 t / cum ( 575x1.6 ) : 920 tonnes

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 ( 605 x 6 / 2.0 ) : 1815 sqm

Depth of stripping : 0.25 m

Qty of stripping with 5 % extra area ( 1815 x 1.05 x 0.25 ) : 476 cum

Output of dozer per hr with 50 min / hr working for stripping : 100 cum

Time required for stripping 476 cum ( 476 / 100 ) : 4.76 hours

Consider 6 hours including time for levelling stripped siol / dozer shifting time.

Time required for stripping for one day embankment work 575 cum : 1.00 hour

3. Collection of soil for embankment :

Deploy one 0.50 cum capacity shovel for 8 hours for digging and loading soil.

Deploy 4 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 ( 605 x 1.20 ) : 726 cum

Output of dozer for levelling per hour : 250 cum

Time required for levelling 726 cum ( 726 / 250 ) say : 3.00 hours

5. Watering :

Generally soil in the 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 575 cum

of embankment will be about 5 tanker loads of 8000 ltrs each. Deploy 8000 ltr capacity water

tanker for 5 hours daily for watering before rolling. Deploy 5 hp pump for 2.5 hours.

6. Compaction :

Soil collected for embankment layer gets compacted to some extent during levelling.

Generally 8 to 10 passes of vibratory pad foot roller is adequate for achieving specified density

control of 95 percent.

Effective length of roller drum : 1.90 m

Speed of roller per hour : 4.0 km

Thickness of layer : 0.3 m

Number of roller passes to achieve specified density control : 9 Nos
