What is meant by a 'spot check' testing approach?

• A. Occasional tests on critical areas to verify ongoing compliance.
• B. Testing every layer in every area.
• C. No testing is needed.
• D. Test only after project completion.

Answer: (A)

Spot checking means doing quick, targeted inspections in selected, critical areas during construction to verify that work is meeting specifications. It’s a sampling approach: you test a few representative spots rather than every layer in every area. This helps catch issues early and allows timely corrections without the time and cost of full-scale testing. It isn’t about testing nothing, nor about testing only after the project is finished, and it isn’t about examining every portion of the work.
