AIA Document A133™–2019 is intended for use on projects where a construction manager, in addition to serving as adviser to the owner during the preconstruction phase, also provides construction of the project with a guaranteed maximum price. The construction manager provides the owner with a guaranteed maximum price proposal, which the owner may accept, reject, or negotiate. Upon the owner’s acceptance of the proposal by execution of the Guaranteed Maximum Price Amendment (Exhibit A), the construction manager becomes contractually bound to provide labor and materials for the project and to complete construction at or below the guaranteed maximum price. The document divides the construction manager’s services into two phases: the preconstruction phase and the construction phase, portions of which may proceed concurrently in order to fast track the process. A133-2019 is drafted to be used in conjunction with a new Insurance and Bonds Exhibit (Exhibit B) which is a critical part of the agreement, and should be discussed with legal and insurance counsel.
