Inspection process
Mock-up
Also called: mockup, sample panel, field mock-up
A mock-up is a full-size sample of a repeating assembly — an exterior wall section, a masonry panel, a bathroom, a window and flashing detail — built and approved before the crew runs it across the whole project. Once accepted, it stops being a sample and becomes the standard: the finished work has to match it. It settles arguments about "acceptable" before they can happen at scale.
Why it matters
A specification describes intent; a mock-up shows the actual result — the mortar color, the reveal, the flashing lap, the finish. Approving one gives the crew a physical target and gives QC something concrete to inspect against, instead of relitigating workmanship on every unit.
How it shows up on site
The mock-up is built early, walked by the architect and owner, marked up, corrected, and then formally accepted. Sometimes it stays standing on site as the reference for the duration; the initial phase inspection of the real feature is measured against it.

Knowing the term is step one. Proving it is the job.
RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
