Instructions: C402™ – 2018, Standard Form of Agreement Between Architect and Consultant for Special Services



AIA Document C402–2018 is intended for Consultant’s services that are limited in scope and/or do not extend to the construction phase of the Project. C402 is appropriate for specialized service descriptions, such as modeling, planning, feasibility studies, post-occupancy studies, specification writing, kitchen design, hardware schedules, elevators, lighting, fire protection, security systems, and carpet carvers. AIA Document C402–2018 provides only the terms and conditions of the agreement between the architect and the consultant. The description of services is left entirely to the parties and must be inserted in the agreement or attached in an exhibit. This Agreement “flows down” only the copyrights and licenses and progress payment provisions of the prime agreement. For all document details and a record of changes, see the summary »
