A friend wants to build a 2 story concrete and hollow block house. The site is near the beach in Dauin. The proposed contract by an architect has the cost of materials at 50% and the other 50% of the cost as professional fee, labor and and 5% contingency. Are contingency fees kept by the contractor. I have reviewed the quotation and all the materials appear to be competitively priced but the labor seemed very high. The quote was very detailed including things like coco lumber and plywood for forming. It even listed 38 rolls of electrical tape. Any thoughts on this please.
