When inspecting driven pile installation, the inspector should record the number of blows per foot primarily to:
Answer: Calculate bearing capacity using driving formulas
Blow count per foot is used with driving formulas (e.g., ENR or WEAP) to estimate the bearing capacity of driven piles.
Which condition requires an inspector to STOP work immediately on an excavation in a Type C soil?
Answer: No sloping, benching, or shoring present in an excavation over 5 feet deep
OSHA requires excavations in Type C soil deeper than 5 feet to have adequate cave-in protection; absence of protection is an imminent danger.
A slump test on a concrete batch shows 5 inches when 4 inches is specified with a ±1-inch tolerance. The inspector should:
Answer: Accept the load since it is within tolerance
A slump of 5 inches falls within the ±1-inch tolerance of the 4-inch specification (acceptable range 3–5 inches), so the load should be accepted.
When inspecting masonry construction, the inspector verifies that mortar joints are tooled at the CORRECT time. What is that time?
Answer: When the mortar is thumbprint hard
Mortar joints are tooled when thumbprint hard to compress the mortar surface and improve weather resistance and bond.
An inspector notes water ponding on a newly placed asphalt surface. This most likely indicates:
Answer: Inadequate cross-slope or improper surface elevation
Ponding water on pavement indicates that the surface lacks the required cross-slope or has low areas due to grade control errors.
Which of the following is a non-destructive test method used to assess the integrity of existing concrete structures?
Answer: Impact echo testing
Impact echo is a non-destructive method that uses stress wave reflections to detect internal flaws, delamination, and voids in concrete.
During steel erection inspection, an inspector finds that high-strength bolt holes are misaligned and a drift pin is being used continuously to force alignment. The CORRECT response is to:
Answer: Stop the practice and require reaming or rejection of the connection
Continuous drift pin use to force misaligned holes indicates fabrication or erection error; holes must be properly reamed or the member rejected.
