NOVEMBER 16, 2011
Good foundation soil should be available at responsible depth. Nearness of schools, hospitals, market, etc. are considered good for residential site but these facilities do not carry any significance in the selection site for other public buildings. This aspect saves quite a bit in the cost of the building.
