Problem 1 (2 point) A masonry faade consisting of 4,800 square feet is to be constructed for a building. The total cost per worker-hour is estimated to be $46.50 and the total estimated cost of the labor is for this task is $19,000. Assuming 8-hour work days and a crew of 6 workers, how many days should be allowed to complete this task? What is the production rate (square feet per hour) that the crew must attain to keep the project on schedule and within the budget? Problem 2 (2 point) The first building constructed by a contractor required 1,850 worker-hours for completion. The improvement rate (learning curve) for additional, identical buildings is expected to be 90%. a) How many hours will be required to complete the 4th building? b) How many hours will be required to complete the 23rd building? c) If he uses a four-man crew, how many total work days (8-hour days) should the contractor allocate in his schedule to complete buildings 15 through 17? d) Realistically, do you think the calculated duration from part c) for buildings 15 through 17 will be too short, too long, or about right? Why? Problem 3 (2 point) Describe two ways an expected project delay due to rainfall can be incorporated into a construction schedule. Normal = = = I No Spac...

The contractor believes that the learning rate per tower will be 0.80 for additional towers. How many towers will have to be built before the time per tower is reduced to 3,000 worker-hours. How much time will be required for the 16th tower
