Estimation and Valuation Practices
Academic Year - 2017-18
3. Cubic Contents Estimate (Based on Rough Cost)
The cubic contents of a building means plinth area x height of the building. The height is
taken from top of floor level to top of roof. The cubic contents of the proposed building are
multiplied with cubic rates arrived at for the similar construction i.e. total cost of construction
divided by cubic contents = cost per cubic meter.
Documents attached are as in No. 2
(Administrative approval is granted on rough cost estimate)
4. Detailed Estimate
After getting Administrative approval on rough cost estimate, detailed estimates are
prepared. In this, the estimate is divided in to sub-heads and quantities of various items are
calculated individually. In the end of the detailed quantities, an abstract of cost giving quantities
of each item and rate of every item according to the sanctioned schedule of rates shall be
attached. In case of non-schedule rates i.e. rates which are not given in the sanctioned schedule
of rates, proper analysis of rates shall be attached. If however the work proposed to be
constructed is located in a remote place, the provision for the carriage of the material shall be
added in the estimate to avoid any excess over the administratively approved estimate later on.
Detailed specifications & report should also be attached with the estimate. Technical sanction is
given on detailed estimate.
The detailed estimate shall also provide for the cost of approach road, water supply, electric
installations and acquisition of land etc, so as to call it a comprehensive estimate.
5. Annual repair estimate
In order to keep building and roads in perfect condition, annual repairs should be carried
out as follow:(i) In case of a building-white washing, oiling and painting of doors and windows, cement plaster
repairs (inside & outside), repairs of floors etc. In no case this annual repair amount should
increase more that 11/2% to 2% of the capital cost of the building.
(ii) In case of a road-filling patches, maintenance of beams etc.
6. Special repair estimate
If the work cannot be carried out of the annual repair funds due to certain reasons
resulting in the genuine increase in cost, then special repairs estimate is to be prepared.
The reason of increase may be:(i) In case of a building-opening of new doors, change of floors, replastering walls etc.
