B503–2017, Guide for Amendments to AIA Owner-Architect Agreements

This guide provides guidance regarding the issues covered in owner-architect agreements, and it provides model language that may be used to amend or supplement owner-architect agreements. Standard form agreements typically require modification to tailor them to individual projects. The model language in this guide may be used to create modifications that may be made directly in the owner-architect agreement or attached in a separate document.

The information and model language in this guide is presented by issue, such as Insurance, and Standard of Care. This guide is not a standard form document. Model language is sometimes presented in several alternative versions, and some language presented may not be appropriate for a particular situation
