During inspection of a concrete slab on grade, 'curling' refers to:
Answer: Warping of slab edges due to differential shrinkage between top and bottom surfaces
Slab curling occurs when the top surface dries and shrinks faster than the bottom, causing edges and corners to lift off the subgrade.
Which AWS standard governs structural welding of steel in building construction and is most commonly referenced by CCI inspectors?
Answer: AWS D1.1 — Structural Welding Code – Steel
AWS D1.1 is the primary standard governing the welding of structural carbon and low-alloy steel used in building and bridge construction.
What type of inspection is required for high-strength bolted connections designated as 'slip-critical'?
Answer: Pre-installation verification and rotational capacity testing plus final torque or turn verification
Slip-critical connections require pre-installation verification of bolt assembly components and either direct tension indicators, torque wrench, or turn-of-nut verification for every bolt.
A construction inspector observes that a concrete column has been placed with the vertical rebar at a spacing larger than shown on drawings. The correct response is to:
Answer: Stop work, document the non-conformance, and notify the engineer of record before proceeding
Any deviation from approved structural drawings is a non-conformance that must be documented and referred to the engineer of record for disposition.
In masonry construction, what does 'prism testing' determine?
Answer: The compressive strength (f'm) of the assembled masonry system
Masonry prism tests are used to verify the specified compressive strength f'm of the combined masonry unit and mortar assembly.
When inspecting cast-in-place concrete foundations, what is 'cold joint' and why is it structurally significant?
Answer: A plane of weakness where previously placed concrete has hardened before fresh concrete is placed against it
A cold joint is a construction defect where partially cured concrete does not bond with fresh concrete, creating a weak plane that can fail under load or allow water infiltration.
Shear studs welded to structural steel beams in composite floor construction are inspected primarily for:
Answer: Height above the beam flange, spacing, and weld quality using bend testing
Shear stud inspection verifies correct height, spacing per drawings, and weld quality through a 30-degree bend test to confirm proper fusion.
