AIA Document B144–1993 is an amendment to an Owner/Architect agreement for use in circumstances where the architect, already under contract to perform architectural services for the owner, agrees to provide the owner with a package of construction management services to expand upon, blend with, and supplement the architect’s design and construction contract administration services described in the Owner/Architect agreement. For use and execution of a document, see its instructions »



This document is an amendment for use in circumstances where the Architect agrees to provide the Owner with a package of construction management services to expand upon, blend with, and supplement the Architect’s design and other construction administration services described in several AIA Owner-Architect agreements. The Architect’s role as an adviser to the Owner is preserved in AIA Document B144 ARCH-CM, and the services provided under this Amendment may be readily incorporated with the Architect’s other services as described in many Owner-Architect agreements and in the General Conditions of the Contract for Construction. Unlike AIA’s guides for amending particular documents, this document is a standard form amendment rather than a model form.


This document is intended to be used in conjunction with other AIA Documents; however, care must be taken to insure that the scope of services and the defined terms in this Amendment are coordinated with the scope of services and defined terms in the underlying agreement and general conditions documents. This is particularly true if this Amendment is used in conjunction with agreements or general conditions documents published after 1993.

Under this document, it is not intended that the Architect provide the Owner with a Guaranteed Maximum Price (GMP) or determine the means, methods, or safety requirements for the project by contracting directly with sub-contractors. 

Although this document is philosophically similar to the AIA’s Construction Manager-Adviser (CMa) documents, B144 ARCH-CM should not be used in conjunction with any of the CMa documents, since an underlying premise of B144 ARCH-CM is that there are only three primary players on the project: the Owner, the Architect (who is providing construction management services) and the Contractor. Alternatively, the CMa documents, envision a fourth player on the team who serves as an independent construction manager.


Changes from the previous edition.

This is the first edition of AIA Document B144 ARCH-CM. Although similar in its description of services to AIA Document B801™CMa, this new document has no direct precursor.
