Who determines the amount of concrete protection that is needed for each part of the project?

• A. Engineer
• B. Architect
• C. Ironworker
• D. Contractor

Answer: (A)

Concrete protection, or cover, is decided as part of the structural design to ensure durability and fire resistance of reinforced members. The structural engineer evaluates factors like exposure to moisture and corrosive elements, fire rating requirements, member size, concrete strength, and applicable codes (such as ACI). Based on that analysis, the engineer specifies the minimum distance from the outer surface to the reinforcing bars, and this becomes part of the project drawings and specifications. The architect focuses on appearance and layout, not the durability-driven cover requirements. The contractor and ironworker then place the reinforcement and pour the concrete so that the actual cover matches the engineer’s specified dimensions.
