How many samples of surfacing 800 sq. ft. of Misc?

• A. 2
• B. 3
• C. Sufficient to determine
• D. 5

Answer: (C)

The idea is that sampling for surfacing work should be enough to determine whether the material meets the required specifications. For 800 square feet of miscellaneous surfacing, there isn’t a universal fixed number of samples to take; the correct approach is to collect enough samples to establish conformance with the spec. This means you consider factors like how variable the material is, the critical quality attributes (thickness, texture, compaction, finish), and the acceptance criteria. If a small number of samples isn’t enough to reveal variability, you take more until you can confidently judge whether the area meets the standard. Fixed counts like a specific number of samples don’t reliably ensure this confidence, so “sufficient to determine” best captures the practical need.
