Instructions: C203™ – 2017, Standard Form of Consultant’s Services for Commissioning



AIA Document C203–2017 replaces AIA Document B211™–2007, Standard Form of Architect’s Services: Commissioning. C203 was updated in 2017 as a “C” series document. An owner can still use C203 to hire an architect to perform commissioning services; however, C203 can also be used to hire commissioning professionals from other backgrounds. C203 includes (1) provisions describing the consultant’s role to assist in preparing the Owner’s Project Requirements, (2) a detailed description of the consultant’s Commissioning Plan, (3) provisions related to commissioning-related design reviews, and (4) provisions related to the consultant’s role in commissioning during the construction phase of the Project. C203 should be incorporated into an owner/consultant agreement, such as C103-2015, Standard Form of Agreement Between Owner and Consultant without a Predefined Scope of Consultant’s Services. C203 is a scope of services document only and may not be used as a stand-alone owner/consultant agreement. For all document details and a record of changes, see the summary  »
