Post-tensioned concretePost-tensioned concrete rough-in inspection checklist
Post-tensioned concrete 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 ACI, the applicable building code. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The GC's superintendent with the PT subcontractor's foreman, walking the deck ahead of the pre-pour inspection.
When in the schedule
After tendons are placed and tied and before concrete is placed, since the drape and hardware are unrecoverable once the pour starts.
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.
Tendon placement
- 2 photos
Profile and drape set to the support bar heights on the drawings
High and low points at the locations shown, support bar heights measured along the tendon against the placing drawings, not set to a flat chair height.
- 2 photos
Sheathing continuous and undamaged
Extruded sheathing intact along each tendon, nicks and tears taped and repaired, couplers and transitions sealed before the pour.
Anchorage
- 2 photos
Anchorage hardware and pocket formers placed and square
Dead-end and live-end anchors seated against the edge form, pocket formers square and tight, back-up bars or bursting reinforcement per the detail.
Cover
- 1 photo
Concrete cover to the tendon verified
Top and bottom cover to the sheathing checked at high and low points against the drawings, tendons tied down so they don't float during the pour.
What usually sends this back
The failures are almost always the evidence, not the work
- Support bar heights set to a uniform chair height instead of the profile, flattening the drape so the tendon doesn't develop the design moment.
- Sheathing nicked or torn during placement and left unrepaired, letting grout or paste bond an unbonded tendon or letting water reach the strand.
- Anchorage pocket formers not seated square to the edge form, so the anchor bears at an angle when it's stressed.
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 7 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 post-tensioned concrete rough-in checklist cover?
- 4 items across 3 sections, covering tendon placement, anchorage, cover. 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 GC's superintendent with the PT subcontractor's foreman, walking the deck ahead of the pre-pour inspection.
- When in the schedule should this walk happen?
- After tendons are placed and tied and before concrete is placed, since the drape and hardware are unrecoverable once the pour starts.
- Why does every item ask for a photo?
- 7 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 post-tensioned concrete rough-in inspection?
- Support bar heights set to a uniform chair height instead of the profile, flattening the drape so the tendon doesn't develop the design moment. Sheathing nicked or torn during placement and left unrepaired, letting grout or paste bond an unbonded tendon or letting water reach the strand. Anchorage pocket formers not seated square to the edge form, so the anchor bears at an angle when it's stressed.
- 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.
