29. When you are calculating the percent complete for an entire project, more than
one answer might be possible. The project manager says the percent complete is
about 60%, the cost engineer says it is 65%, the computer program says it is 57%,
and the owner says it should be 50% (according to her representative's feedback).
You calculate it on the basis of how much time has elapsed and how much time
is given in the contract; your result is 70%. Can you explain these confusing and
“conflicting” numbers?
30. On the basis of the information given in the previous exercise, do you think the
project is in trouble (with regard to the budget and the schedule)? How did you
conclude this?
31. Explain the procedure for initiating and processing pay requests.
32. This exercise is for persons who use Oracle Primavera P6 software: you created a
project without feeding the program any budget or resources information. After
the first update, the scheduling report says the project is 16.7% complete. Do you
know how the program determined this number? How accurate is this number?
33. The EV analysis involves comparing what happened with what should have hap-
pened. Explain this statement with regard to both the budget and the schedule.
34. Amason contracted with a general contractor to build an exterior wall from 8-inch
CMUs. The wall is 82 feet long and 8 feet high. 17 The mason must finish the wall
in 3 days and gets paid $4 per block. At the end of day 1, the mason has installed
220 blocks. Her actual cost (including overhead and profit) is $836. Analyze the
situation with regard to both the budget and the schedule.
35. Draw the S curve for the masonry job in the previous exercise.
16 To run an electric wire through a conduit by using resilient “fish tape” or a “snake.”
17 Do not forget the CMU face dimension (including the mortar joint): 8 inches by 16 inches.
