Progress Photo Documentation
Systematic, dated photographs of the jobsite taken at regular intervals throughout construction, especially of work that will later be covered up, such as structural connections, MEP rough-in behind drywall, or waterproofing before backfill, building a visual record for closeout, disputes, and future maintenance.
Why it matters
Once drywall closes over a rough-in, the photos are the only record left of what's actually behind the wall, which makes them genuinely valuable evidence in a dispute, an insurance claim, or a future renovation years down the line.
On a real project
A project engineer photographs every MEP rough-in run before drywall closes it in, organized by date and location, and uploads the set to the project's document management software the same day.
Who this matters most to
A Project Engineer typically owns the task of capturing and organizing progress photos throughout construction.
Where this goes wrong
A crew closes in a wall without photographing the plumbing rough-in behind it. Months later a leak requires locating a shutoff valve, and with no photo record of where the line actually runs, the facilities team has to open up drywall exploratively just to find it.
