AIA Contract Document Numbering System

The American Institute of Architects provides the standard set of contracts, and associated documents, that are used throughout the construction industry in the United States. These documents have been developed over many years and many projects so they are widely accepted by architects, contractors, and owners. The documents provide agreements for various sizes and types of projects, as well as a number of different organizational structures between the various contracted parties. As the construction industry evolves, the AIA modifies the documents or creates new documents as needed.

The AIA provides a full list of current AIA construction documents. You can also purchase a license to use the documents at the official AIA Contracts website.

We also have an article about construction document sheet order and numbers.
