AIA Document B101–2007 is a one-part standard form of agreement between owner and architect for building design and construction contract administration. B101–2007 was developed to replace B141–1997, Parts 1 and 2, and B151–1997, but it more closely follows the format of B151–1997. Services are divided traditionally into basic and additional Services. Basic services are performed in five phases: schematic design, design development, construction documents, bidding or negotiation, and construction. This agreement may be used with a variety of compensation methods, including percentage of construction cost and stipulated sum. B101–2007 is intended to be used in conjunction with AIA Document A201–2007, General Conditions of the Contract for Construction, which it incorporates by reference. NOTE: B151–1997 was retired in May 2009.
