A's answer is 14.3 weeks and $62,857
B's answer is $55,357 and 12 weeks
1. Suppose that you have been asked to take orer projetraget on a small project involving installation of 5,000 LF of metal ductwork in a building. The job was originally estimated to take 10 weeks, and you begin work after six weeks into the project. The original estimate assumed that each linear foot of ductwork would cost $10, representing $6 in labor costs and $4 dollars in material cost. The expected production rate was 500 LF of ductwork per week. The data conceming this project available from your firm's job control infomation system is as follows: Weekly Unit Cost (S/LE) Labor 12.00 Quantity Placed (LF) To Date 250 Total Cost Week Week Material Total Week To Date 250 4.00 16.00 4000 4000 8.57 12.57 4400 4.00 350 600 8400 3. 10.67 4800 6.67 4.00 450 1050 13200 a. Based upon the data available, determine the variances and indices and provide conclusions for the status of the project based upon the most up-to-date data. Predict the final cost and time required to finish the project using this data. (15 points). b. Suppose that you assume that the productivity achieved in week 3 (i.c., quantity placed) would continue for the remainder of the project. How would this affect your forecasts in (a)? Prepare new forecast for total cost and time to complete the project based on this assumption for the remainder of the 5,000 LF of material using the same cost data associate with the productivity for week 3.
