AIA Document A101™–2007 is a standard form of agreement between owner and contractor for use where the basis of payment is a stipulated sum (fixed price). A101 adopts by reference, and is designed for use with, AIA Document A201™–2007, General Conditions of the Contract for Construction. A101 is suitable for large or complex projects. For projects of a more limited scope, use of AIA Document A107™–2007, Agreement Between Owner and Contractor for a Project of Limited Scope, should be considered. For even smaller projects, consider AIA Document A105™–2007, Agreement Between Owner and Contractor for a Residential or Small Commercial Project. NOTE: A101–2007 replaces AIA Document A101™–1997 (expired May 31, 2009).
