Which schedule type is commonly used to plan and control construction projects, showing critical paths and activity durations?

• A. Baseline schedule
• B. Updated monthly schedule
• C. Recovery schedule
• D. CPM schedule

Answer: (D)

The key idea is using a scheduling method that reveals which tasks drive the project’s finish date and how long each task takes. A CPM schedule does just that by building a network of activities with their durations and dependencies, then calculating the earliest and latest start and finish times. It identifies the critical path—the sequence of activities with no room to delay without delaying the project—so you can see exactly which tasks must stay on track to meet the deadline. This makes CPM scheduling the primary tool for planning and controlling construction projects, since it directly shows both the activity durations and which activities determine the project’s completion date. Baseline schedules, updated monthly schedules, and recovery schedules are all important, but they don’t inherently emphasize the critical path and task durations in the way a CPM schedule does.
