Inspection process
In-process inspection
Also called: in-process check, during-installation inspection
In-process inspection happens during the work rather than at the end of it: checking rebar placement while it can still be tied, watching weld technique as connections are made, verifying a membrane lap as it goes down. It is the middle of the three-phase rhythm — preparatory before the work, in-process during, final after — and it is the phase where a drift gets corrected on the spot instead of becoming a finished condition someone has to write up.
Why it matters
Once work is complete, every miss is either accepted or torn out. Inspecting while it is in progress means a spacing error, a missed backing, or a bad technique gets fixed by the crew that is already there, at almost no cost. It is the difference between coaching the work and grading it.
It is also where consistency is set on repetitive work. Catching a problem on the first unit in-process keeps it from being reproduced on every unit that follows, which is exactly what a final-only inspection cannot do.
How it shows up on site
A super or QC rep checking rebar and embeds before the pour is called, walking a membrane as it is laid, or spot-checking fastener spacing while a crew frames — with concealed conditions photographed before the next step covers them.
