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
