NCARB Project-Management Exam - Topic 2 Question 15 Discussion

Posted by Tanesha on Jun 01, 2026 at 05:18 PM

According to ATA owner-architect agreements, who is responsible for the cost of evaluating significant substitutions proposed by the contractor, subcontractors, or suppliers and the cost of making subsequent revisions to drawings, specifications, and other documentation?

Suggested Answer: A

Comprehensive Detailed Explanation:

According to AIA B101 (or ATA equivalent) Section 3.6.4.2, if the contractor proposes a substitution that is not part of the base contract, the cost to evaluate it and revise any documents (if accepted) is considered an Additional Service by the architect. Therefore, the owner bears that cost if they authorize the architect to proceed with the evaluation.

This seems similar to a question we had on project management costs; I think it was the owner who had to cover those expenses.

I remember a practice question where the architect had to handle revisions, but I can’t recall if that applies here too.
