True or False: The CM's responsibilities change drastically when the Owner accepts a GMP proposal.

The correct response is that the responsibilities of the Construction Manager (CM) do not change drastically when the Owner accepts a Guaranteed Maximum Price (GMP) proposal. The CM continues to oversee the project's execution, ensuring it remains within the agreed-upon price, schedule, and quality standards. The acceptance of a GMP indicates that the owner and the CM have to a certain degree finalized the cost expectations and project details, but the core responsibilities such as management, coordination, and communication remain largely consistent.

In most cases, the adoption of a GMP signifies that the project is entering a more defined phase where budget control becomes essential. However, it does not fundamentally alter the CM's essential roles and obligations. They remain focused on delivering the project successfully from start to finish, managing subcontractors, and maintaining safety and compliance standards.

Other options might imply that there are significant changes in responsibilities that accompany the GMP acceptance, which is not the case. The responsibilities are more about management and execution rather than transitioning to a completely different role or scope of work.
