Which parties shall jointly prepare a schedule in accordance with the progress of work?

• A. Contractor
• B. Architect
• C. Engineer
• D. Contractor and Architect and Engineer

Answer: (D)

Coordinating the project timeline is best done through a joint effort by the contractor, architect, and engineer. The schedule should be prepared in line with progress of work, meaning it lays out when design decisions, submittals, approvals, procurement, fabrication, and on-site activities will occur and how they depend on each other. When all three parties contribute, the plan captures design and engineering requirements alongside construction realities, creating a realistic baseline. The contractor provides practical durations and sequencing based on resources and methods, while the architect and engineer outline design milestones, required reviews, and technical constraints. This integrated approach improves coordination, highlights the critical path, and gives a solid framework for monitoring progress and handling changes. If the schedule is prepared by a single party, important design dependencies or approval lead times may be overlooked, leading to unrealistic timelines. Therefore, the schedule should be prepared jointly by the contractor, architect, and engineer.
