What is a primary purpose of a project schedule in coordinating with trades?

• A. Estimates total project cost.
• B. Assigns final responsibilities to workers.
• C. Sets sequence, milestones, and deadlines to minimize conflicts and delays.
• D. Determines the color palette.

Answer: (C)

Coordinating multiple trades hinges on a clear plan for when each task happens. A project schedule sets the sequence of work, key milestones, and deadlines, so trades know the order and timing of activities. This helps prevent conflicts, like two trades needing the same space at the same time, and reduces delays by aligning starts and finishes with the overall progress. For instance, painters should start after drywall is finished and prepped, while electricians complete rough-in before walls are closed. Milestones provide progress checkpoints, and deadlines keep the project moving toward completion. The other options aren’t about sequencing and timing: estimating total cost is a cost task, assigning final responsibilities is about who does what rather than when, and choosing a color palette is a design decision.
