Acoustical ceilingsAcoustical ceilings rough-in inspection checklist
Acoustical ceilings 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 ASTM C635 / C636, the applicable building code. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The ceiling foreman setting grid, or the GC's superintendent confirming above-ceiling trades are complete before tile is released.
When in the schedule
After the grid is hung and before tile is loaded, and only once the MEP work above the ceiling is complete and its own inspections are closed.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Grid layout and suspension
- 2 photos
Grid laid out square with balanced border tiles
Main runners and cross tees square to the room, layout centered so border tiles are balanced and not slivered, grid level across the field.
- 2 photos
Hanger wires spaced and tied to structure
Wires at the required spacing along the mains, plumb and tight, tied to building structure and not to duct, pipe or conduit.
Seismic and perimeter
- 2 photos
Seismic bracing and perimeter clips where required
Bracing wires, compression struts and perimeter attachment or clearance installed per the seismic design, edge conditions and expansion gaps as detailed.
Above-ceiling readiness
- 2 photos
Above-ceiling MEP complete and inspected before tile
Ductwork, piping, wiring and fire-stopping above the ceiling finished and their inspections closed, nothing left that needs the plenum reopened.
What usually sends this back
The failures are almost always the evidence, not the work
- Tile dropped in before the above-ceiling inspection signs off, so the whole field has to come back out to reach a damper or a junction box.
- Hanger wires spaced to the easy structure instead of the required layout, or tied to ductwork and pipe instead of the building structure.
- Seismic bracing and perimeter clips left off where the design requires them because the grid 'looked tight,' caught only at the seismic inspection.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 8 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this acoustical ceilings rough-in checklist cover?
- 4 items across 3 sections, covering grid layout and suspension, seismic and perimeter, above-ceiling readiness. 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 ceiling foreman setting grid, or the GC's superintendent confirming above-ceiling trades are complete before tile is released.
- When in the schedule should this walk happen?
- After the grid is hung and before tile is loaded, and only once the MEP work above the ceiling is complete and its own inspections are closed.
- Why does every item ask for a photo?
- 8 of the 4 items call for photo evidence. 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 acoustical ceilings rough-in inspection?
- Tile dropped in before the above-ceiling inspection signs off, so the whole field has to come back out to reach a damper or a junction box. Hanger wires spaced to the easy structure instead of the required layout, or tied to ductwork and pipe instead of the building structure. Seismic bracing and perimeter clips left off where the design requires them because the grid 'looked tight,' caught only at the seismic inspection.
- 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.
