AIA: American Institute of Architects

Who They Are & What They Create

The American Institute of Architects (AIA) is the professional organization for architects in the United States. While not a traditional SDO in the same vein as others on this list, AIA plays a critical role in the architecture and construction industries by developing standard contract documents and professional practice guides. These documents provide a legal and ethical framework for client-architect agreements, project delivery, and other aspects of professional practice, ensuring a consistent and fair process for all parties.

Detailed History

The AIA was founded in New York City on February 23, 1857, by 13 architects who sought to “promote the scientific and practical perfection of its members” and “elevate the standing of the profession.” Prior to this, anyone could call themselves an architect without any formal training or standards. Early AIA efforts focused on creating a professional identity for architects, establishing a code of ethics, and advocating for the profession’s interests. The organization’s standard contract documents, first published in 1888, have become the industry standard for outlining the roles and responsibilities of architects, owners, and contractors. AIA has also been a key advocate for sustainable design and public policy that supports the built environment.
