PERT (Program Evaluation and Review Technique) uses three time estimates for each activity. What are they?
Answer: Optimistic, most likely, and pessimistic
PERT uses optimistic (O), most likely (M), and pessimistic (P) durations to calculate a weighted average expected time for each activity.
A Finish-to-Finish (FF) relationship with a lag of 5 days means:
Answer: The successor must finish at least 5 days after the predecessor finishes
A Finish-to-Finish relationship with a positive lag requires the successor to finish a specified number of days after the predecessor finishes.
Which document serves as the baseline against which schedule progress is measured throughout a project?
Answer: The approved project schedule baseline
The approved schedule baseline is the frozen snapshot of the original plan used to measure deviations and report schedule performance.
What is 'fast-tracking' in construction project scheduling?
Answer: Overlapping phases or activities that would normally be done sequentially
Fast-tracking compresses the schedule by performing phases in parallel rather than sequentially, though it often increases risk and coordination demands.
Which scheduling method assigns probability distributions to activity durations to model schedule risk?
Answer: Monte Carlo simulation
Monte Carlo simulation runs thousands of iterations using probability distributions for activity durations to produce a probabilistic project completion date.
In a Precedence Diagramming Method (PDM) network, activities are represented by:
Answer: Nodes (boxes), with arrows showing dependencies
PDM (also called Activity-on-Node) places activities in boxes connected by arrows that define the logical relationships between them.
What is the purpose of a 3-week lookahead schedule on a construction project?
Answer: To identify and remove near-term constraints so field crews can execute work without interruption
A 3-week lookahead is a short-interval schedule used to identify and resolve upcoming constraints such as material deliveries, inspections, and labor needs.
