Civil Engineering QUESTION #2133
Question 1
The critical path in a CPM (Critical Path Method) network is defined as:
  • The longest path from start to finish of the project, determining the minimum project duration — activities on the critical path have zero float and any delay directly delays project completion✔️
  • The path with the most activities from start to finish
  • The path with the highest total cost of activities
  • The shortest path from project start to finish
Correct Answer Explanation
The critical path is the longest duration path through the project network from start to finish. It defines the minimum possible project duration. Activities on the critical path have Total Float (TF) = 0: TF = Late Start − Early Start = Late Finish − Early Finish. Any delay to a critical activity delays the entire project by the same duration. Non-critical activities have positive float — they can be delayed without affecting project completion.
