When substitutions are considered for approved materials, who must approve them in writing?

• A. Building department or engineer approval required in writing; confirm meets code and performance.
• B. Only supplier approval required.
• C. No formal approval needed.
• D. Substitutions approved by site supervisor only.

Answer: (A)

When substitutions are considered for approved materials, you must obtain written approval from the building department or a licensed engineer. This ensures the substitute still meets the applicable codes and performs to the required standards, with a formal record that reviews the impact on safety, structural integrity, fire resistance, durability, and overall design intent. Supplier approval might confirm compatibility, but it doesn’t guarantee code compliance. A site supervisor alone isn’t authorized to approve substitutions that affect code requirements, and skipping formal approval can lead to code violations and warranty issues.
