1.
During inspection, concrete cylinders fail compressive strength tests below specified design
requirements. What is the correct action?
A. Approve structure anyway
B. Require structural evaluation and corrective action
C. Ignore test results
D. Reduce load requirement
Answer: B
Rationale: Low compressive strength indicates structural risk requiring engineering evaluation.

is the risk?
A. Improved strength
B. Corrosion and durability failure
C. Faster curing
D. Lower cost
Answer: B
3.
During inspection, rebar is found not properly secured before concrete pour begins. What should the
inspector do?
A. Allow pour to continue
B. Require correction before pouring concrete
C. Ignore condition
D. Reduce inspection scope
Answer: B
