Hi Jyosna,
I reviewed the documents sent
by you and came with the following conclusion. The quotation given by your
contractor is very high. He is trying to
artificially inflate the quantities too along with the price that he is
quoting. For example, In item number 17
at ground floor the contractor mention that RCC 1:2:4 roof slab concrete 5 inch
thick and described that he would charge for the quantity 755 cft where as per the
review of the plan it seems that the calculation comes out to 1380 * 5/12 = 575
cft.
This means that the
contractor has inflated the quantity by 755 – 575 = 180 cft and assuming that we
take the rate that he has proposed Rs 173 per cft the over charging comes out
to Rs 41,140/- Now even after stating
that my calculation is off by 5 to 10% as I do not have the complete building
plan with the height of doors, windows, elevation, sectional and structure
drawing still the difference is huge and this was the analysis of just one
item.
Also, In item number 35
window grills are taken as 362 Kg. It can be verified by yourself with the
number and size of the windows available in your drawings. It seems that the quantity quoted by the
contractor is very high and also rate quoted by him is very high as compared to
the market rates.
I recommend that we do the
following.
You
send us the complete plan of the building with details, such as
a.
windows door etc.
b.
Elevation,
c.
section of the
buildings including height of the ground floor first floor etc.
d.
Structural design
of the building which shows size of
foundation / column, beams slabs and arrangement of steel bars. We
recommend that you take our services for a complete detailed estimate which
will cost you Rs. 6000(An additional Rs 5500 as you have already paid 500) If you take our service for preparation of
detail estimate it will provide you all the quantities of all the items required
in the building and the prevailing market rates with the specifications. Once
you have this information you can very well negotiate with the contractor for
reducing the rates and which can save you in lakhs. In
order for the detailed estimate we will need structural design drawings also.
If you want us to make those structural drawings then we can do that for an
additional Rs 8,000.
Also,
on another note your contractor has shown RCC 1:2:4 where as as per the new
guidelines supplied by CPWD (Central public works department) for taking in
view of earth quake safety the ratio of RCC should not be less than 1:1.5:3.
Please
let me know if I can be of any other help.
Thanks
