Post-tensioned concrete

Post-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.

Who runs it

The GC's superintendent with the PT engineer, resolving flagged tendons and detailing exposed anchorages.

When in the schedule

After stressing records are reviewed and the deck is walked, before pockets are hidden by finishes and the structure is loaded.

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.

01

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.

    1 photo
  • Tendon or anchorage damage repaired

    Damaged strand, wedges or anchors repaired or replaced per the approved method, spalled pocket concrete made good, photographed after repair.

    1 photo
02

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.

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.

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 3 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.

Common questions

What does this post-tensioned concrete punch checklist cover?
3 items across 2 sections, covering resolution, pocket closure. 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 does every item ask for a photo?
3 of the 3 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 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.
