AIA Document B108™–2009 is a standard form of agreement between Owner and Architect for building design and construction contract administration that is intended for use on federally funded or federally insured projects. AIA Document B108–2009 was developed with the assistance of several federal agencies and contains terms and conditions that are unique to federally funded or federally insured projects. B108 sets forth five traditional phases of basic services: schematic design, design development, construction documents, bidding or negotiation, and construction. Two other types of services are delineated in the document: optional services and additional services. B108 is structured so that either the owner or the architect may be the entity providing cost estimates. NOTE: B108–2009 replaces AIA Document B181™–1994, which expires on May 31, 2011.
