What is the consequence if scour is not addressed around foundations?

• A. Increases load capacity.
• B. Improves appearance.
• C. No safety impact.
• D. Foundation undermining and potential collapse.

Answer: (D)

Scour around foundations erodes the soil that supports the base of a structure. When water removes material from around the footing, the bearing capacity drops and voids can form under the foundation. With less support, the structure can settle, tilt, or crack, and in severe cases it can fail or collapse. That’s why ignoring scour has serious safety implications—the foundation is undermined and the structure can fail. The other options don’t fit because scour does not increase load capacity, it does not improve appearance, and there is definitely a safety impact.
