FAQs: Owner/Architect agreement B133™–2019 (CMc)

What is AIA Document B133–2019, Standard Form of Agreement Between Owner and Architect, Construction Manager as Constructor Edition? 

AIA Document B133–2019 is a standard form of agreement between owner and architect intended for use on projects where an Owner employs a Construction Manager to act as an adviser during the preconstruction phase. 

At a time to be mutually agreed upon by the Owner and the Construction Manager, and in consultation with the Architect, the Construction Manager prepares a guaranteed maximum price proposal or control estimate, as applicable, for the owner’s review and acceptance. Thereafter, the construction manager constructs the project on a cost of the work plus a fee basis, either with or without a guaranteed maximum price, and the architect provides contract administration services during the construction phase. 

B133–2019 assumes that the construction manager will provide cost estimates and schedules for the project. B133–2019 is intended to be used with AIA Document A201®–2017, General Conditions of the Contract for Construction, which it incorporates by reference and either A133™–2019, Standard Form of Agreement Between Owner and Construction Manager as Constructor where the basis of payment is the Cost of the Work Plus a Fee with a Guaranteed Maximum Price or A134™–2019, Standard Form of Agreement Between Owner and Construction Manager as Constructor where the basis of payment is the Cost of the Work Plus a Fee without a Guaranteed Maximum Price. For all document details and a record of changes, see the summary » 

 

What services does the architect provide under B133–2019 that are particular to the construction manager as constructor delivery model? 

The architect provides several services under B133–2019 that are specific to the construction manager as constructor delivery model. The architect has a general duty to consult with the construction manager throughout the project. This differs from a conventional project, in which the builder does not become involved until construction, because the construction manager provides a range of preconstruction services that must be coordinated with the architect’s design services. The architect must also submit a schedule of its services to the construction manager for inclusion into the project schedule. Thereafter, the architect participates in developing and revising the project schedule as it relates to the architect’s services. 

The architect also provides a range of services related to the construction manager’s guaranteed maximum price proposal or control estimate. For example, the architect considers construction manager requests for substitutions and provides clarifications or interpretations pertaining to the drawings and specifications prior to the owner’s acceptance of the guaranteed maximum price proposal or control estimate.  The architect also assists the owner in reviewing the guaranteed maximum price proposal or control estimate once the construction manager has provided those documents to the owner.
