Which scheduling technique uses probabilistic activity durations to estimate the likely completion time of a construction project?
Correct answer: C. Program Evaluation and Review Technique
- A. Critical Path Method
- B. Line of Balance method
- C. Program Evaluation and Review Technique
- D. Bar chart method
Explanation
PERT uses optimistic, most likely, and pessimistic time estimates to deal with uncertainty. CPM normally uses a single deterministic duration for each activity, making it the obvious alternative trap.

About Construction Management and Estimation
Construction management covers planning, scheduling, resource control, contracts, procurement, site organisation, safety, quality assurance and project documentation. Estimation includes quantity take-off, rate analysis, bill preparation, valuation and cost control, with attention to the difference between direct and indirect costs and between an estimate, a tender and a final account.
