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 expired on May 31, 2009.
