In the context of construction project management, which of the following statements is/are true:

1. A dummy activity will consume time and resources
2. The programme evaluation and review technique (PERT) is best suited for projects with large uncertainties in the duration of activities
3. A Gantt chart is commonly used for identifying the ‘critical path’ of activities in a project
4. Free float is the amount of time by which the start of an activity can be delayed without causing a delay in the start of a following activity

Correct answer: The programme evaluation and review technique (PERT) is best suited for projects with large uncertainties in the duration of activities

Solution

PERT is designed to handle projects where activity durations are uncertain, allowing for probabilistic estimates and better risk management, making it ideal for such scenarios.
