4. A call to bid was advertized in the national circulated newspaper for the construction of a transmission line from a mini-hydroelectric power plant to the substation which is 5.0354 km away. Tantalized timber electric posts must be placed at an intervals of 50 meters. The electric posts must be 30 feet long, 8" dia. At the tip and 12" dia. At the butt. The power house is 15 meters from the first electric post and the substation is 20 meters from the last electric post. Compute the estimated cost for the job using the following data: Cost of one tantalized timber post 30 ft long = P9,800.00 each delivered to the site. Laborer at P300.00/day- 5 laborers can dig and erect 3 posts per day. Electrician at P500.00 per day - 4 electricians can strung wires complete 150 meters per day. Electric wire costs P11.00 per meter. Use only 5 laborers and 4 electricians for the project and an electrical foreman P1,000.00 per day. Compute the direct cost and add 10% contingencies and 25% profit
