B101 Risk Alignment Checklist.
Do I Need C401s?
Evaluate how your project’s contracts stack up with these questions:
- Do your consultant terms align with your own primary Owner-Architect agreement?
- Is each consultant’s “portion of the project” aligned with your commitments to the Owner?
Together, the right agreements create a framework for risk protection and cross-functional collaboration for construction projects. In our document coordination series, we highlight the essential pairings within the AIA Contract Document library.
Hiring consultants is part of delivering a comprehensive design. Consultants may be structural, mechanical, or civil engineers, landscape designers, or specialty professionals. Though independent consultants, they operate within the commitments you’ve already made to the Owner.
When you pair B101: Standard Form of Agreement Between an Owner and Architect with C401: Standard Form of Agreement Between Architect and Consultant there is fundamental alignment across agreements. C401 incorporates your primary agreement by reference. It defines each consultant’s services as a specific “portion of the project,” grounding their scope within the larger program.
C401 also uses a flow-down structure: to the extent applicable, consultants assume the same obligations toward you that you assume toward the Owner. This alignment reduces the risk of gaps between what you promise the owner and the performance your consultants deliver.
At the same time, C401 preserves professional boundaries. Consultants remain independent contractors responsible for their own methods and means. You are not responsible for their acts or omissions simply because you retained them. This is a critical line the C401 draws.
As projects become more complex, such as when consultants retain subconsultants, or teams rely on shared BIM environments, clear coordination becomes even more important.
