When verifying the installation of geotextile fabric in a retaining wall drainage system, the inspector should confirm that:
Answer: Seams overlap the minimum specified distance and fabric is protected from UV degradation before backfill
Geotextile seams must meet minimum overlap requirements and the fabric must be quickly covered to prevent UV degradation that reduces strength.
The purpose of a pre-installation inspection for structural steel anchor bolts is to verify:
Answer: Bolt size, projection, spacing, and template alignment before concrete is placed
Anchor bolt size, projection height, spacing, and template alignment must be confirmed before concrete placement because corrections after are extremely difficult.
When performing an inspection of epoxy-coated rebar, the inspector should reject bars that have holiday (coating damage) exceeding what threshold without repair?
Answer: Damage exceeding 2% of the bar surface area in any 12-inch length
ASTM A775 allows holiday repair but limits unrepaired damage; damage exceeding 2% of surface area in a 12-inch length requires repair or rejection.
During shotcrete application inspection, the inspector notices excessive rebound being incorporated back into the work. This is significant because:
Answer: Rebound material has a higher water-cement ratio and lower strength
Rebound material has lost cement during impact and incorporating it back into the work reduces strength and increases the effective water-cement ratio.
An inspector observes that form release agent has been applied to reinforcing steel before concrete placement. The CORRECT action is to:
Answer: Require removal of contaminated bars and cleaning before concrete is placed
Form release agents on rebar break the bond between steel and concrete, significantly reducing structural performance; contaminated bars must be cleaned or replaced.
What is the purpose of a mock-up inspection on a construction project?
Answer: To verify materials, workmanship, and appearance before full-scale production begins
Mock-ups establish an accepted standard of workmanship and appearance that all subsequent production work must match.
When inspecting fire-resistive spray-applied fireproofing (SFRM), the inspector verifies thickness using a:
Answer: Pin-type thickness gauge per ASTM E605
ASTM E605 prescribes the pin-type gauge method for measuring the thickness of spray-applied fireproofing in the field.
