What does this entrance floor mats and grilles rough-in checklist cover?

15 items across 4 sections, covering recess depth and frame, layout and orientation, drainage, anchorage and protection. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The mat installer or concrete crew setting the recess, or the GC's superintendent walking the opening before the floor finish closes around it.

When in the schedule should this walk happen?

While the slab or recess is still open, before the finished flooring is set to the frame and before the recess depth is locked in.

Why do these items ask for a photo?

9 of the 15 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 an entrance floor mats and grilles rough-in inspection?

The recess poured to the wrong depth, so the finished mat sits proud or sunken against the floor and becomes a trip edge no shim fixes. The frame set out of level or twisted, so the finished floor meets it with an uneven margin all the way around. No drainage or weep provided in the recess for an entrance that sees water and snowmelt, so the pan holds standing water under the mat.

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.

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.

Recess depth and frame

Frame set to depth and flush to the finished floor line
Recess depth matched to the mat so the top sits flush with the finished floor, frame level and square, margin even for the flooring to meet.
Well bottom flat across its full length and width
Straightedge laid across the recess floor in both directions, no humps or low spots that would leave the grille bearing on high points and rocking.
Well length and width match the approved shop drawings
Recess measured both ways and on the diagonals against the shop drawings, sized for the grille plus the frame clearance the manufacturer lists.
Frame and grille components match the approved submittal
Frame profile, material and finish, and the carton or packing labels for the grille, checked against the approved submittal before the frame is set.
Frame corners joined tight with no open miter
Each frame corner welded, keyed or clipped as the manufacturer details, faces aligned with no gap or step where the finish will butt the corner.

Layout and orientation

Well located and squared to the door opening per the drawings
Well position measured from the threshold and side walls against the drawings, long edges parallel to the door line so the grille reads square to the entrance.
Direction of traffic marked for the tread rails
Travel direction through the entrance marked at the well and compared with the shop drawings, so the rails will run across the traffic as detailed.
No photo
Grille opening type confirmed where an accessible route crosses
Where an accessible route crosses the well, the approved submittal checked for a heel-proof grille with openings suited to wheelchairs and canes.
No photo
Floor finish on each side of the frame identified
The finish meeting each frame edge (tile, carpet, resilient or sealed concrete) and its thickness noted, frame height coordinated so every side can finish flush.
No photo

Drainage

Recess drains where water is expected
Weep or drainage provided in the pan at an exterior-facing entrance so water and snowmelt do not pool under the mat.
No photo
Drainage requirement for each well checked on the drawings
Each mat well checked against the drawings for a floor drain, a weep or neither, and the answer confirmed with the super before the recess is poured.
No photo
Well drain body set at the low point where the drawings show one
Where the drawings show a drain in the well, drain body set at the recess low point with the well floor falling to it and the tie-in coordinated with plumbing.
No photo

Anchorage and protection

Frame anchored and protected until the floor is placed
Frame anchored so it holds position during the pour or floor set, recess protected and clean so debris does not set into the finish around it.
Frame anchors at the spacing the manufacturer lists
Anchor straps, clips or fasteners on every side at the manufacturer's spacing and embedment, set into the slab or grout before they are concealed.
Frame bearing flange fully supported with no voids
Grout or setting bed packed full under the frame's bearing leg so it does not flex under carts and heel loads once the grille is in.

What usually sends this back

The failures are almost always the evidence, not the work

The recess poured to the wrong depth, so the finished mat sits proud or sunken against the floor and becomes a trip edge no shim fixes.
The frame set out of level or twisted, so the finished floor meets it with an uneven margin all the way around.
No drainage or weep provided in the recess for an entrance that sees water and snowmelt, so the pan holds standing water under the mat.
