A CLEARIFICATION ABOUT RATE OF BITUMINOUS BOARD FOR EXPANSION JOINTS

The rate for Supplying, fitting and fixing of bituminous board in expansion joints has

been provided as item no. 5. 3. 8 in the present schedule of rate, Water Resources

,effective from 01.10.2012, which is Rs.45579.10/sqm. It is erroneous one which will be

cleared from following para.

The schedule of rate Book of Darbhanga zone ,which was effective from 08.11.2005 ,

has given the following rates for bituminous shaltex board for expansion joints:-

Thichness of the board Rate Rs.per sqm Percentage increase with respect to

12 mm thick board

12 mm thick 332.0 0%

18 mm thick 487.0 146.58 % , say 147 %

25 mm thick 581.0 175%

The above rates are mentioned on page no. 53 of the said Schedule of rate of

Darbhanga zone , whose photcopy has been attached hereby.

In the same way ,the rate of the same board is mentioned on page no. 89 of the

present Schedule of Rate, WRD, Bihar, effective from 01.10.2012 in following way:-

Thichness of the board Rate Rs.per sqm Percentage increase with respect to

12 mm thick board

12 mm thick 346.0 0%

18 mm thick 507.0 146.53 % , say 147 %

25 mm thick 37587.0 10863% Which is highly abrupt.

If we compare the incremental rate of Darbhanga zone and present Schedule of rate,

the incremental percentage from 12 mm to 18 mm is same( i.e. 147 %) ,but in 25 mm thick

it is highly abrupt and not acceptable in any case and the same figure has been taken for

analysis part too, so it has brought incremental error in the final rate. It is clearly a printing

mistake and it needs correction.

In the logical way ,we can increase the rate of 25 mm thick board by 175 % of the

rate of 12 mm thick board on the basis of Darbhanga zone Schedule of Rate. In this way,

the rate for 25 mm thick board becomes 1.75 x 346 = Rs.605.50 per sqm say Rs. 610.0 /sqm.

The analysis part becomes as follows for 25 mm thick board for S/F/F :-

Taking out 9.3 sqm

Bituminous board- 25 mm thick-9.3 sqm @610.0/sqm = 5673.00

Saltexprimer 2.25 kg @ 42.0/ kg = 94.50

Labour

Mason Gr. II 0.25 NO. @ 190.00 = 47.50

Unskilled mazdoor 0.25 no. @157 = 39.25

Total= 5854.25

Add 20 % as overhead charge & C.P. 1170.85

Total= 7025.10

Add 1 % cess 70.25

GRAND TOTAL 7095.35

So , rate per sqm = 7095.35 / 9.3= 762.9409677

Say Rs. 765.00/sqm

But it should be approved by the Departmental Schedule of Rate Committee
