Administration第 77 / 110 题
During construction the plumbing is inspected in stages. Which sequence correctly orders the common inspections?
a.Underground (below-slab), rough-in (top-out), then final
b.Final, rough, underground
c.Rough, final, underground
d.Final, underground, rough
解析
Inspections follow the work: underground or below-slab piping is inspected and tested before it is covered, then the rough-in or top-out after walls are piped but before they are closed, and finally the final after fixtures are set. Each stage must pass before the next is covered. Skipping a stage forces uncovering completed work.
