CCM Cost and Time Management 4

Question 1

What does a Schedule Performance Index (SPI) of 1.15 indicate about a construction project?

Accepted Answer

The project is completing 15% more work than planned per time period

Answer

SPI = EV / PV; an SPI greater than 1.0 means the project is ahead of schedule, earning more value than planned.

Question 2

A construction manager applies resource leveling to the project schedule. What is the most likely outcome?

Accepted Answer

Extended project duration or shifted activity dates

Answer

Resource leveling resolves resource over-allocations by adjusting activity start dates, which often extends the project duration.

Question 3

Which document establishes the approved cost baseline for a construction project?

Accepted Answer

Cost performance baseline

Answer

The cost performance baseline is the approved, time-phased budget used to measure, monitor, and control project cost performance.

Question 4

What is the primary purpose of an S-curve in construction project management?

Accepted Answer

To compare planned versus actual cumulative cost or progress over time

Answer

An S-curve plots cumulative planned value and actual cost over time, providing a visual comparison of budget versus expenditure.

Question 5

A construction activity has an optimistic duration of 4 days, most likely of 7 days, and pessimistic of 16 days. What is the PERT expected duration?

Accepted Answer

8.0 days

Answer

PERT expected duration = (O + 4M + P) / 6 = (4 + 28 + 16) / 6 = 48 / 6 = 8.0 days.
