Question 1

Which scheduling technique uses probabilistic time estimates to account for uncertainty in activity durations?

Accepted Answer

Program Evaluation and Review Technique (PERT)

Answer

PERT uses three-point estimates (optimistic, most likely, pessimistic) to calculate expected durations and account for schedule uncertainty.

Question 2

A construction project has a Schedule Performance Index (SPI) of 0.85. What does this indicate?

Accepted Answer

The project is 15% behind schedule

Answer

An SPI less than 1.0 means the project is behind schedule, with 0.85 indicating work is progressing at only 85% of the planned rate.

Question 3

What is the primary purpose of a Look-Ahead Schedule in construction management?

Accepted Answer

To plan work 2-6 weeks in advance and ensure resource readiness

Answer

A Look-Ahead Schedule (typically 3-6 weeks) bridges the master schedule and daily work plans by identifying upcoming constraints and confirming resource availability.

Question 4

When predecessor activity B cannot start until successor activity A is 50% complete, this relationship is called:

Accepted Answer

Start-to-Start with lag

Answer

A Start-to-Start with 50% lag means B can start only after A has progressed 50%, representing an overlapping dependency.

Question 5

Which of the following best describes 'float' in a construction schedule?

Accepted Answer

The time an activity can be delayed without delaying the project completion

Answer

Float (or slack) is the amount of time an activity can slip without extending the overall project completion date.
