relevant.

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 guide

lines listed under ' General notes on schedule of rates ' 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. 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

Less Lead charges for 1 km Rs: -29.30

Additional lead charges Rs: 7.20

No loading and un-loading charges shall be added.

7. Cement content specified for cement concrete works in the item description is based on

theoritical design mix computations. The basic rate shall be adjusted upword or downword

including lead, loading and un-loading charges for any varions in cement content based on trial

mix studies furnished by Q.C unit.

8. The quantities of materials including wastage, requirements for incidentals etc., for workingout additional lead charges shall be as per the statement of requirement of materials under

this section.

9. The basic rates are exclusive of cost of dewatering and desilting. For the perticular reach of

canal where dewatering and desilting are contemplated 2 percent of basic rate shall be added

to all items in the estimate for that reach towards dewatering and desilting during execution of

to required level and profile, cost of all materials, machinery, labour, placing the excavated soil

neatly in dump area or for the formation of service road / embankment as directed etc.,

complete with initial lead upto 1 km and all lifts.

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 canal excavation the space available may not permit positioning of the

tippers on either side of the shovel. Generally, one tipper has to move after loading to position

the next tipper for loading. Assuming one cycle time extra the corrected cycle time for theshovel will be : ( 6 x 20 / 60 ) : 2.00 min

Output for 5 tippers per day ( 5 x 19.80 x 8 ) : 792 cum

Further, assuming about 90 percent of excavation by deploying shovel and about 10 percent

excavation mainly for trimming the canal to final profile by manual labour the daily progress ofexcavation will be : ( 792 / 0.9 ) 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 792 cum insitu soil.

Deploy 5 tippers of 5 cum capacity for 8 hours for disposal of 792 cum insitu soil.

SECTION: CANAL AND ALLIED WORKS. YEAR : 2007-08 ITEM No: 6.a

ITEM: Excavation in hard rock of all toughness including boulders above 0.6 m diameter (0.113 cum)

by blastingfor canals, cut-off trench of embankment, filter / catch water drains etc., adopting a

combination of wagon drill holes of not more than 100 mm dia. and jack hammer holes including

levelling the bed and minimising damage to side slopes in water prism by adopting any one or a

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

rock neatly in approved dump area as directed etc., with initial lead upto 1 km and depth of

cuts upto 18 m below ground level.Note: For depth of cut more than 18 m below ground level increase the basic rate by 5 %.

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.

I. By using Jack hammers for drilling :

Assume 10.80 m width of canal at the bench level and 1.25 m average depth of cutting.

Assume side slopes of 0.25 horizontal to 1 vertical.

Generally, the length of canal bench to be excavated per blast shall not be more than 7 m to

avoid tight muck pile requiring higher digging time for shovel.Sectional area of excavation ( 10.80 + 10.175 ) x 0.5 x 1.25 : 13.11 sqm

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

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.

control of 95 percent.
