Visible concrete delamination should be handled by which action?

• A. Proceed With Repairs Only After A Formal NBIS Review.
• B. Ignore It If There Is No Spalling.
• C. Continue Regular Service Without Assessment.
• D. Assess Extent, Potential Load-Bearing Impact, And Consider Temporary Posting Or Repairs.

Answer: (D)

Visible concrete delamination signals potential hidden deterioration that could affect a bridge member’s ability to carry load. The correct response is to thoroughly assess how widespread the delamination is and what it means for load-bearing capacity, then decide on temporary posting or repairs as needed. This involves determining the extent of damage, evaluating whether the affected area could still carry the intended loads safely, and considering traffic restrictions or posting to protect the structure and the public while the assessment and repairs are planned. After the evaluation, a repair plan should be developed and carried out, which may include removing loose material, addressing exposed reinforcement, and applying appropriate patching or reconstruction methods to restore structural integrity. Ignoring the condition or continuing service without assessment can allow hidden deterioration to advance and lead to unexpected, larger-scale failure.
