Which statement is false?

Which statement is false?

• A. Deficient contract documents is a common cause of disputes.
• B. As the numbers of prime contractors on a project increase, the need to carefully coordinate contract documents increases.
• C. The roles of the CM as specified by the AIA and CMAA standard forms of agreement are significantly different.
• D. After the owner accepts a CM's proposed GMP as contemplated by the CMAA CM-at-Risk Series documents, the responsibilities and duties are essentially the same as if the owner and CM were using the AIA GMP documents.

Answer: (D)

The main concept here is how contract form and GMP documents shape the CM’s responsibilities and risk, and how CMAA and AIA forms differ in practice. The statement about GMP acceptance being essentially the same under CMAA CM-at-Risk and AIA GMP documents is false because these forms allocate duties, authority, and risk differently. Even after the owner accepts a CM’s proposed GMP under CMAA’s CM-at-Risk framework, the CM’s obligations, cost-control processes, change-management procedures, and the owner–CM relationship are not identical to what they would be under AIA GMP documents. The differences in document language drive distinct expectations and liabilities, so the duties after GMP acceptance are not simply interchangeable. The other statements are true in substance: deficient contract documents commonly lead to disputes; as the number of prime contractors on a project grows, the need for careful coordination of contract documents increases; and the CM’s roles in AIA and CMAA standard forms reflect different emphases and allocations of responsibility, even though both sets of forms govern CM-at-Risk arrangements.
