1. A contractor needs to accelerate his construction schedule. He is in the process of placing wall forms for the pouring of a concrete wall. His ideal productivity standard is 5 person- hours per 100 square feet of contact area (SFCA). He has a 4 man-crew placing the wall forms. The hourly rate of a worker is $20 per hour. Each worker is paid time-and-one-half for any hours in excess of 8 hours a day. If a worker is required to work Saturday or Sunday, he is paid double time for this period. Assume the total project quantity = 80,000 SFCA. Assume that the contractor has gathered the following data regarding his loss of efficiency with overtime: Days 5 Hours 11 10 Total weekly hours 55 70 Inefficiency (%) 17 27 7 a) Calculate the unit labor cost associated with the two alternative overtime schedules. b) Assume that the contractor is penalized $1,000 per day if the work lasts in excess of 20 weeks. Which overtime schedule would you suggest to minimize the overall cost of doing the work?
