Question: A project schedule indicates that the 'roof sheeting' activity has a float of 5 days, and the 'truss installation' activity must be completed before 'roof sheeting' can start. If 'truss installation' is delayed by 3 days, what impact does this have on the project's critical path?
Answer options:
- The critical path is delayed by 3 days. ✅ The critical path is not affected.
- The critical path is delayed by 5 days.
- The critical path is accelerated by 2 days.
Correct answer: The critical path is not affected.
Explanation: Float is the amount of time an activity can be delayed without delaying the project's critical path or subsequent activities. Since the delay (3 days) is less than the available float (5 days) for the 'roof sheeting' activity, the critical path will not be affected. The float for 'roof sheeting' will be reduced to 2 days.
