Planning & EstimatingQuestion 639 of 700

During interior work, in what order must inspections generally occur before the walls are closed up?

a.Rough framing and rough mechanical/electrical/plumbing are inspected and approved before insulation, and insulation is inspected before drywall covers it.
b.Insulation is installed and inspected first, then rough framing, then the MEP rough-in.
c.Drywall may be hung before the rough MEP inspection to keep the schedule moving.
d.Only a single final inspection is required; the intermediate inspections are optional.

Explanation

Correct: work is inspected while still visible. Rough framing and rough MEP are approved first, then insulation is installed and inspected, and only then is drywall hung to cover everything. Installing insulation before framing/MEP approval, hanging drywall before rough MEP, or skipping intermediate inspections would conceal work that must be inspected first.
