Post-tensioned concretePost-tensioned concrete punch checklist
Post-tensioned concrete punch is where small misses become callbacks after the crew has demobilized. This checklist walks the finished work the way the owner and the next trade will see it, with the photo that closes each item instead of a note that reopens it. Work is commonly verified against ACI, the applicable building code. 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.
Resolution
Out-of-range elongations investigated and resolved
Each tendon outside the calculated range evaluated by the engineer, cause identified and disposition documented before signoff.
No photoTendon or anchorage damage repaired
Damaged strand, wedges or anchors repaired or replaced per the approved method, spalled pocket concrete made good, photographed after repair.
No photoA stressing record exists for every tendon on the drawings
Tendon marks on the stressing records reconciled against the placing drawings for the whole deck, so no tendon is missing a pressure and elongation entry.
No photoAnchorage zones and slab edges walked for cracking
Soffits and edges near anchors, and slab-to-wall or column restraint points, checked for cracks; any found mapped by location and sent to the engineer for evaluation.
Pocket closure
All pockets patched before finishes cover them
Every stressing pocket confirmed packed and patched flush before the area is closed in, none left open behind a later finish.
Pocket patches sounded and checked for shrinkage or staining
Patches tapped for hollow spots and looked at for shrinkage gaps, cracking or rust bleed at the edge; loose or stained patches cut out and redone per the detail.
Grout vents and inlets on bonded tendons cut and sealed
On bonded systems, vent and inlet tubes cut back and sealed per the grouting procedure so no open path is left to the duct.
No photo
Turnover records
Every core or drilled anchor in stressed concrete has a scan
Penetrations made after stressing matched to a tendon scan or locating record before the hole was drilled, with any strike reported to the engineer.
No photoStressing records and tendon layout in the turnover package
Reviewed stressing records, the engineer's dispositions and the as-built tendon layout filed for the owner, so later coring and repairs can locate tendons.
No photo
What usually sends this back
The failures are almost always the evidence, not the work
- An out-of-range elongation left unresolved because the tendon 'reached pressure', with no engineer evaluation of the discrepancy.
- A stressing pocket left unpatched behind a later finish, exposing the anchorage to moisture.

Common questions
6 answers
- What does this post-tensioned concrete punch checklist cover?
- 9 items across 3 sections, covering resolution, pocket closure, turnover records. 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 engineer, resolving flagged tendons and detailing exposed anchorages.
- When in the schedule should this walk happen?
- After stressing records are reviewed and the deck is walked, before pockets are hidden by finishes and the structure is loaded.
- Why do these items ask for a photo?
- 3 of the 9 items call for photo evidence, 3 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 post-tensioned concrete punch inspection?
- An out-of-range elongation left unresolved because the tendon 'reached pressure', with no engineer evaluation of the discrepancy. A stressing pocket left unpatched behind a later finish, exposing the anchorage to moisture.
- 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.
