The AIA family of forms is listed in alphabetical order. The two most common categories are Series A contracts, called ownership and contractor contracts, and Series B contracts, called property and architect contracts. The AIA document A105 is intended for small and short-term projects for which payment to the contractor is based on a fixed price. Like the A104, the A105 is a full-fledged agreement that contains separate terms and conditions. If the AIA A105 is used, the B105 is the corresponding agreement between the owner and the architect. The A104 is considered an abbreviated agreement, as it is a separate agreement that does not require the use of a separate document to the general terms and conditions of sale. If the owner and the developer choose one of the two cost-plus payment methods, the parties must complete a Schedule A of the A104 containing details of the project costs. AIA document A105™-2017 is a stand-alone agreement with its own terms and conditions. AIA document A105-2017 is intended to be used in a small and short-term project for which payment to the contractor is based on a fixed amount (fixed price). A105-2017 replaces AIA document A105-2007, the standard form for the agreement between the owner and the contractor for a small residential or commercial project. For larger and more complex projects, other AIA owner/contractor contracts are more appropriate. AIA documents A105-2017 and B105™-2017, Standard Short Form of Agreement Between Owner and Architect, include the Small Projects family of documents.
