Which term describes repair work of a significant nature that calls for the engineering design of remedial measures?

• A. Redundancy
• B. Rehabilitation
• C. Resurfacing
• D. Relief

Answer: (B)

When repair work is substantial and requires engineering design of remedial measures, the right term is rehabilitation. It encompasses actions that restore a structure’s function and safety through meaningful changes to the structure—such as strengthening, replacing key components, or upgrading details—based on structural analysis and design. That’s more than routine maintenance or surface work; it involves engineering planning and design to address the underlying deficiencies and extend the structure’s life.

Relating to the other terms: redundancy is about creating multiple load paths to improve reliability—not about repairing a deficient structure. Resurfacing covers renewing a surface layer, which is typically much less involved and doesn’t require designing remedial structural measures. Relief isn’t a standard term used to describe this kind of repair work in structural engineering.
