1. You are an estimator for a roofing subcontractor. You are trying to estimate the direct cost and duration of the placement of a polyethylene underlayment and flat clay tiles on a 60ft40ft roof. Table 1 shows the line items to complete the scope of work and necessary labor resources. - Placement of tiles (Task B) can be started once underlayment placement (Task A) is completed. - A roofer gets paid $42.10 per hour and works 8 hours a day - Assume 15% waste on polyethylene underlayment and 10% waste on clay tiles - Polyethylene underlayment is sold in rolls of 300SF for $250 - Clay tiles are sold in boxes of 150 pieces for $655 - Daily job indirect cost is $200, and contingency is 10% of total direct cost - Profit margin is 10% of the total direct and indirect cost a. What is the total direct cost and duration (in hours) of the job? (20 points) b. What should be the subcontractor's lump sum bid? (5 points) c. If the actual productivity of the underlayment crew turns out to be 24Sq/ day, what will be the profit of the subcontractor? (10 points) Table 1. Tasks to perform your scope
