On the publication of the new American Institute of Architects (AIA) form agreements in the Architects Handbook of Professional Practice, all of the recommended form contracts delineated therein contain provisions for arbitration of disputes. The procedures governing any arbitration are to be in accordance with the Construction Industry Arbitration Rules of the American Arbitration Association (AAA). These rules, newly developed as of March 1966, replace all prior procedures formerly followed under AIA document D-201—the old Standard Form of Arbitration Procedure. This latter document has been withdrawn from circulation and neither it nor the procedures contained therein are any longer avaikble in print. It is the purpose of this article, in discussing the new Construction Industry Arbitration Rules and Procedures, to show how they came about, and to reveal how the new arbitration clauses are used by the industry. The applicable law concerning arbitration under construction contracts will also be discussed.
