Post-tensioned concrete inspection checklists

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.

Verified against

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?

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.
