A bill was raised by contractor which read as follows
1.) Excavation in normal soil upto 1.5m - 250 cum
2.) Excavation in normal soil 1.5m to 3m - 240 cum
3.) Excavation in soft rock - 350 cum
4.) Excavation in hard rock - 250 cum
5.) Filling with available soil - 825 cum
6.) Filling with bought out soil - 1100 cum
How can I verify the above quantities, especially for item
no. 5 & 6?
What checks are necessary before releasing the bill ?

Answer / murali vasudevan
In the extant case the total excavation is
250+240+350+250=1090 CuM. Quantity of filling = 1090 -
(Minus) Quantity of Concrete or other materials that have
gone in to the foundation below Ground Level. (For Eg Take
this as 200 Cum. Then filling required = 1090 - 200 = 890
CuM. But the actual qty of soil required will be less than
890 when we consider the bulking of excavated
sand/materials. So in practise the Qty of soil required for
re-filling the excavated portion = 890-5% of 890 = 845.5
CuM.
Another elaboration is as follows :-
Total Excavation = A
Total materials used for foundation
(Concrete+Rubble+Brick etc) = B
Material required for refilling = C = (A-B)- (A-B)*5/100
Hope this solves your problem..

Answer / u.arunkarthick
here the total excavation qty is 1090 m3, then minus the qty
of concrete used for footing and add consolidation of soil
as 2 to 3%, example if we excavate 1m*1m*1m = 1m3 of
excavated earth is there, then refill that area needs 1.2m3
because of soil consolidation.

Answer / rao
The total qty of filling should always be less than or
equal to the total qty of excavation of all types of soils.
Here in this case, the total qty of filling exceeds the
total qty of excavation, Hence the contractor has raised a
incorrect bill.
Before releasing the bill, the quantities are to be cross
checked with drawings and also practically on site visit.
