Engineering Economics . A call to bid was advertised in a national newspaper for the construction of a transmission line from a mini-hydroelectric powerplant to a substation that is 5,535 meters away. The electric posts must be placed at intervals of 50 meters. The powerhouse is 15 meters from the first electric post, and the substation is 20 meters from the last electric post. Prepare the estimate for the job using the following data: Cost of one post = P 5,000 each, delivered to the site; laborers at P 350 per day. Five laborers can dig and erect 3 posts each day. Electricians at P 450 per day. Four electricians can string wires complete 150 meters per day. Electric wire costs P 40 per meter. Use only 5 laborers and 4 electricians for the project and a foreman at P 500 per day. Compute the direct cost. Add contingencies and profit which is 10% and 25% of the direct cost, respectively.
