AIA Document B101™–2007 is a one-part standard form of agreement between owner and architect for building design and construction contract administration. AIA Document B101–2007 was developed to replace B141–1997 Parts 1 and 2, and B151–1997 (expired 2009), 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 Document, 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.
