The Industry Standard in AEC Contracts for 135+ Years

Since 1887, when the Committee on the Uniform Contract created its first agreement, AIA Contract Documents have set the gold standard for legal agreements in the architecture, engineering, & construction (AEC) industry.

Maintained by the 35+ member AIA Documents Committee—experts in design, construction, law, and insurance—our 300+ documents are reviewed quarterly to reflect case law and industry changes, ensuring they remain current, enforceable, and aligned with best practices.

Discover the AIA Document advantage. Not all standard documents are the same. The AIA Contract Documents are the most widely used standard form contracts in the construction industry because:

• AIA documents are fair.
• AIA documents reflect industry practices, not theory.
• AIA documents reflect changing construction practices and technology.
• AIA documents reflect the law.
• AIA documents are flexible.
• AIA documents are easy to interpret.
