Post-tensioned concrete inspection checklists for the rough-in, final and punch walks: 3 free lists, 11 items and 17 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against ACI concrete practice; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule
- Post-tensioned concrete rough-in inspection checklistrough-in
- After tendons are placed and tied and before concrete is placed, since the drape and hardware are unrecoverable once the pour starts. Run by: The GC's superintendent with the PT subcontractor's foreman, walking the deck ahead of the pre-pour inspection.
- Post-tensioned concrete final inspection checklistfinal
- After the concrete reaches the specified stressing strength, tendon by tendon, and — on bonded systems — after cutoff when the tendons are grouted. Run by: The GC's superintendent with the PT subcontractor's stressing crew and the engineer's field rep witnessing elongations.
- Post-tensioned concrete punch checklistpunch
- After stressing records are reviewed and the deck is walked, before pockets are hidden by finishes and the structure is loaded. Run by: The GC's superintendent with the PT engineer, resolving flagged tendons and detailing exposed anchorages.
What most often sends post-tensioned concrete work back
- 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.
- Elongations written down but never compared against the calculated range, so a tendon short of gauge pressure or elongation slips through.
- Jack pressure gauge out of calibration date, making every elongation reading on that jack unverifiable.
- Grout stopping short of a high point on a bonded tendon, leaving a void where the strand can corrode.
- 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.

Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Common questions
- Which post-tensioned concrete inspections do these checklists cover?
- Post-tensioned concrete rough-in inspection checklist (rough-in): After tendons are placed and tied and before concrete is placed, since the drape and hardware are unrecoverable once the pour starts. Post-tensioned concrete final inspection checklist (final): After the concrete reaches the specified stressing strength, tendon by tendon, and — on bonded systems — after cutoff when the tendons are grouted. Post-tensioned concrete punch checklist (punch): After stressing records are reviewed and the deck is walked, before pockets are hidden by finishes and the structure is loaded.
- Who runs a post-tensioned concrete inspection?

The GC's superintendent with the PT subcontractor's stressing crew and the engineer's field rep witnessing elongations. The GC's superintendent with the PT engineer, resolving flagged tendons and detailing exposed anchorages.

- Which standards is post-tensioned concrete work verified against?
- ACI concrete practice, published by the American Concrete Institute. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 3 lists (11 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper-evident audit trail.
