Planning & EstimatingCâu 638 / 700
Which statement BEST reflects required inspection timing for concealed work?
a.Footings may be poured first and the reinforcing inspected later after stripping the forms.
b.Foundation reinforcement and forms must be inspected before concrete is placed, and underground plumbing must be inspected before the trench is backfilled.
c.Underground piping should be backfilled immediately and inspected by re-excavation only if a problem is suspected.
d.Concealed work is inspected only once, at the final inspection before occupancy.
Giải thích
Correct: inspections of work that will be concealed must occur before it is covered, so foundation steel/forms are inspected before the pour and underground piping is inspected before backfill. Pouring first and inspecting later defeats the purpose. Backfilling before inspection buries the work. A single final inspection cannot verify concealed conditions.
