How should inspectors document a potential hidden defect in a concrete deck?

• A. Ignore undocumented findings and proceed.
• B. Only log defects if visible.
• C. Use non-destructive testing results when available, note limitations, and recommend follow-up or demolition if necessary.
• D. Refer all issues to legal authorities.

Answer: (C)

Documenting suspected hidden defects in a concrete deck requires clearly communicating what is known, what isn’t, and what steps are needed next. When non-destructive testing is used, record the exact methods, equipment, settings, and results, and describe what these findings imply about the deck’s condition. Equally important is noting the limitations of the testing—depth limitations, moisture conditions, access issues, or investigative gaps—so the level of confidence is understood. Based on the data, provide concrete next steps: suggest follow-up testing with appropriate methods, consider destructive sampling (like core tests) if necessary, and, if warranted, point toward demolition or repair guided by a qualified structural engineer. Support your recommendations with practical details such as the precise location, measurements, photos, dates, and who performed the work, and reference any relevant standards or guidelines. This thorough approach protects safety and helps drive appropriate remediation decisions. Ignoring undocumented findings isn’t appropriate, and limiting documentation to what is visibly apparent misses potential hidden problems; involving legal authorities is not the proper channel for standard inspection documentation—professional engineering judgment and proper recommendations within the inspection report are.
