36. A flooring subcontractor must install three types of flooring in an existing
building:

Quantity (SF) a Type Unit Price ($/SF) Total Price ($)

Carpet 2,600 2.30 5,980

Vinyl tile 1,200 2.95 3,540

Ceramic tile 3,330 4.95 16,484

Total 7,130 26,004

a Carpet is usually sold and installed by the square yard. We used square
foot (SF) here for conformity with the other flooring types.

The subcontractor is given 10 days to finish all the work. Assume he has
crews to start all three jobs concurrently. Four days after the start of the work, he
discovers the following:

Type Quantity Installed (SF) Actual Cost ($)

Carpet 1,500 3,150

Vinyl tile 800 2,488

Ceramic tile 750 3,638

Perform an EV analysis of the preceding task:

a. Analyze each subtask (carpet, vinyl tile, ceramic tile) individually; determine its
status with regard to the budget and the schedule.
b. Analyze the entire flooring activity as one unit; determine its status with regard
to the budget and the schedule.
c. How do you combine the answers for parts A and B?
d. On the basis of performance so far, do you believe the subcontractor will finish
the job on time? Within budget? Justify your answer.
e. DrawtheScurvefortheentiretask.
