How to set hold points and witness points

Hold points and witness points are the two ways an inspection and test plan controls who has to be involved before work moves on. A hold point is a hard stop — no advance without a written release. A witness point is an invitation — the party gets notice to observe, but the crew may proceed if they don't attend. Setting them well is a balance: enough control to keep defects visible, not so much that the job stalls waiting on a busy inspector. This guide covers how to place and run them.

For QC managers and superintendents building or negotiating the control points in an ITP before a feature starts.

Step by step

  1. Find the points of no return

    Walk the feature and mark every step after which correction gets expensive or impossible — closing a wall, pouring over rebar, backfilling a trench, energizing a feeder. Those are your candidate hold points.

  2. Make the irreversible steps hold points

    Put a hold point in front of each point of no return. The rule is simple: work stops until the named party inspects and releases it in writing. Silence is not permission at a hold point.

  3. Use witness points where observation matters but stopping doesn't

    For steps where a party should have the chance to watch — a test being run, a critical connection — but where waiting would stall the job, set a witness point. The invitation is mandatory; the attendance is not.

  4. Name the releasing or invited party for each point

    Every point names exactly who releases a hold or is invited to witness — owner's rep, engineer of record, AHJ, specialty inspector, or QC. A point with no named party is a point nobody owns.

  5. Set a genuine, documented notice period

    State the notice the crew owes each party, usually in working days. For witness points this is what protects you: real, logged notice means the crew may proceed if the party doesn't show, without it turning into a dispute.

  6. Record the release, the attendance, or the waiver

    Capture the hold-point release signature, or for a witness point, log whether the party observed or waived and work proceeded. Attach the photos taken at the point so the record shows the party had their chance either way.

What gets missed

  • Making everything a hold point 'to be safe,' which turns the inspector into a bottleneck and trains the crew to work around the stops.
  • Setting witness points with no notice period, so a skipped witness becomes an argument about whether notice was given.
  • Treating a witness point like a hold point — waiting indefinitely for a party who was never obligated to attend.
  • Releasing a hold point verbally over the phone with no written record.
  • Placing a hold point after the point of no return instead of in front of it, so the defect is already buried when the inspector arrives.

Questions people ask

Can the crew proceed if the inspector misses a witness point?
Yes — that's the defining feature of a witness point. If the party was given the agreed notice and didn't attend, the crew may proceed and logs that the party waived attendance. That's why the documented notice matters so much.
Who decides whether a step is a hold or a witness point?
It's negotiated in the ITP before work starts, typically between QC, the owner's rep, and the engineer of record. Regulated and life-safety steps often force a hold point; the rest is a judgment call about risk versus schedule.
