Who should run this inspection?

The panel installer prepping the walls, or the GC's superintendent walking the substrate before the panels bond over it.

When in the schedule should this walk happen?

After the wall board is up and taped and before FRP install, while the substrate can still be corrected and penetrations marked.

Why do these items ask for a photo?

9 of the 13 items call for photo evidence, 10 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a frp wall panels rough-in inspection?

Panels bonded to a wall that was not flat, so the finished FRP telegraphs every ridge and hollow and traps voids behind the sheet. The wrong wall board used behind the panels in a wet area, so the substrate degrades where moisture gets past a joint. Outlet and plumbing penetrations not located before install, so cutouts get hacked in freehand and leave gaps the sealant can not close.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

FRP wall panels rough-in inspection checklist

FRP wall panels rough-in is the last time the work is fully visible. Once the cover inspection passes and the walls, ceilings and slabs close, every defect left behind becomes a demolition bill. This checklist walks the rough-in in the order the work goes in, with the photo each item needs before it gets buried. Work is commonly verified against the applicable building code, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Substrate flat and sound

Wall flat, dry and free of ridges or hollows
Substrate flat within tolerance, joints not proud, surface dry and clean so the adhesive bonds full without voids behind the panel.
Board face prepared the way the adhesive manufacturer requires
Face bare or primed only as the adhesive's instructions allow, with no glossy paint, dust, grease or torn paper where the adhesive goes.
Corners true enough for the corner moldings to seat
Inside and outside corners checked plumb and straight so both legs of the corner molding sit tight to the panel without open gaps.

Moisture-appropriate substrate

Correct backer used for the wet-area location
Moisture-resistant board or the substrate specified for the location behind the panels, not standard board that fails when moisture reaches it.
Room temperature and humidity read against the adhesive's range
Air and wall temperature and humidity read and recorded against the adhesive manufacturer's range, with heat or HVAC set to hold it through cure.

Penetrations located

Outlets and penetrations marked before panels go up
Outlet, switch and plumbing locations marked so cutouts are clean and centered, edges that trim and sealant can close later.
Backing locations for wall-hung items marked for the panel crew
Where shelving, sinks or equipment will fasten through the FRP, backing located and marked so hole layout is known before sheets go up.
No photo

Materials, layout and method

Panel and adhesive labels match the approved submittal
Carton labels show the panel texture, color, thickness and the interior-finish class the code plan requires for the room; adhesive labels match the approved submittal.
Sheets stored flat in the conditioned room before install
Panels laid flat and off the floor in the room for the time the manufacturer lists, not leaned on a wall or kept in a cold trailer.
Panel layout marked from a level line with joints planned
Level base line snapped, joint locations marked so division bars clear outlets and fixtures and no narrow slivers land at corners.
Adhesive and fastening method taken from the manufacturer
Adhesive type, trowel notch and coverage, and whether and where edge or field fasteners are used, confirmed from the manufacturer's instructions for this substrate.
No photo
Trims and moldings counted for every edge condition
Division bars, inside and outside corners, and cap and edge moldings from the manufacturer's system matched to each joint, corner, top edge and termination.
No photo
Expansion gap at base, ceiling and corners set from the instructions
Gap the manufacturer lists at the floor, ceiling, corners and inside moldings known to the crew, with spacers on hand and oversize fastener holes planned.
No photo

What usually sends this back

The failures are almost always the evidence, not the work

Panels bonded to a wall that was not flat, so the finished FRP telegraphs every ridge and hollow and traps voids behind the sheet.
The wrong wall board used behind the panels in a wet area, so the substrate degrades where moisture gets past a joint.
Outlet and plumbing penetrations not located before install, so cutouts get hacked in freehand and leave gaps the sealant can not close.
