Cost Estimation for House Construction
At RAMTEJ Constructions, we have developed a special "Budget
Estimation Calculation" which gives you an approximate
budget needed for the construction of your house.
General Guidelines:
It is a good strategy to know beforehand the requirement of
space, probable cost and approximate quantities of critical
materials. As a rule, the ratio of materials to labour to
overheads is 60:30:10. The current cost of construction is
Rs 600-900 per sq ft depending upon finishing items.
Stages and rough percentage of total
work
To give you an idea of the cost pattern for different
stages, the cost is worked out for a 1000 sq ft house @ Rs
700/- per sq ft.

Yardsticks for some construction
materials
Following table would give an idea of the quantities of
important materials required. If their consumption is
controlled, pilferage and wastage minimized, saving upto 5%
to 8% could be achieved. The quantity required has been
worked out for a house of 1000 sq ft.
