What document outlines the duties and relationships of the Owner, Architect, and Contractor?

The correct choice is the AIA A201, which is a vital document in construction contracts as it delineates the general conditions of the contract for construction. This document is instrumental in outlining the duties, responsibilities, and relationships between the Owner, Architect, and Contractor. It sets forth the fundamental framework governing the interactions among these parties throughout the project lifecycle, addressing various aspects such as roles in project management, communication protocols, contract administration, and processes for dealing with changes or issues that may arise during construction.

AIA A101, while related to an agreement between the owner and the contractor for a stipulated sum, does not focus on the broader relationships and duties among all three parties. AIA B101 specifically relates to the owner-architect agreement, detailing the architect's responsibilities to the owner but not the contractor's role. AIA C201 involves the framework for the architectural services provided in conjunction with a design-build project, which also does not thoroughly address the general conditions and interactions as AIA A201 does. Thus, AIA A201 stands out as the essential document for articulating the roles and responsibilities of each party involved in construction projects.
