A project manager is scheduling tasks for a construction project. The foundation work (Task A) must finish before framing (Task B) can begin. Electrical wiring (Task C) can start any time after framing has started. Which of the following dependency types BEST describes the relationships among these tasks?
Finish-to-Start between Tasks A and B; Start-to-Start between Tasks B and C.
Finish-to-Start between Tasks A and B; Finish-to-Start between Tasks B and C.
Finish-to-Finish between Tasks A and B; Start-to-Start between Tasks A and C.
Start-to-Finish between Tasks A and B; Finish-to-Start between Tasks B and C.
Finish-to-Start (FS) between Tasks A and B: Framing cannot begin until the foundation is completed.
Start-to-Start (SS) between Tasks B and C: Electrical wiring can start once framing has started, without needing to wait for framing to finish.
Therefore, the correct answer is the one that states a Finish-to-Start between Tasks A and B and a Start-to-Start between Tasks B and C.
Other options are incorrect because they either assign dependency types that do not match the task relationships described (e.g., Finish-to-Finish, Start-to-Finish), or they misplace dependencies (e.g., placing dependencies between incorrect tasks). Understanding the correct sequencing ensures the project schedule is accurate and realistic.
