Hold points and witness points: definitions, ITP use, and missed holds

Direct answer: A hold point is a mandatory stop: work cannot proceed until the named inspection is complete and released. A witness point requires notice so the named party can attend, but work may continue after that notice. Both belong on the inspection and test plan. Covering work past an unreleased hold can mean uncovering it later (VDOT QA/QC Minimum Requirements §5.14; IBC 2024 §1704.2.2).

There is no single IBC definition of "hold point" or "witness point." The IBC instead requires that work remain accessible until the special inspection or test is complete. The hold / witness / review labels come from quality-control plans and contracts. The definitions below follow a published state DOT rule and the DoD quality-control guide spec. Your contract may use different words; follow that text.

What is a hold point?

A hold point is a mandatory verification stop. Virginia DOT's published QA/QC rule states that hold points are "mandatory verification points identified within the Construction QA/QC Plan and CPM schedule beyond which work cannot proceed until mandatory verification is performed" (VDOT QA/QC Minimum Requirements §5.14.1).

Place hold points where the quality of the work cannot be checked after the next step covers it: reinforcement before concrete, subgrade before fill, waterproofing before concealment, or high-strength bolting before covering.

The building code states the same idea for special inspections without using the words "hold point": the contractor must keep the work "accessible and exposed" until the special inspections or tests are complete (IBC 2024 §1704.2.2).

What is a witness point?

A witness point is a notice point. The same VDOT rule says witness points "require notification of the Department and/or design team, where applicable. Work may proceed beyond a Witness Point with or without participation by the Department provided proper notification has been given" (VDOT QA/QC Minimum Requirements §5.14.1).

If a design-team certification is also required, VDOT says work still may not proceed until that certification is obtained. Read the contract: some jobs treat a missed witness as a hold.

Typical witness points include fresh-concrete sampling, fill-density tests, and structural-steel QA tasks that the named party should see but that do not, by themselves, stop the next trade.

What is the difference between a hold point, a witness point, and a review point?

PointWork stops?Who must be toldWhat releases itSource
Hold pointYes. Work does not proceed until verification is complete.The party named on the plan (owner's QA, engineer, special inspector, or contracting officer).A written release, signed report, or other record the contract names.VDOT §5.14–5.15
Witness pointNo, if the required notice was given. Work may continue if the named party does not attend.Same as above.The notice record, plus any report the named party later files.VDOT §5.14.1
Review pointNo field stop. A document or test report is reviewed and accepted.The reviewer named on the plan.Acceptance of the record (lab report, certificate, or submittal).Common ITP notation; see the ITP template

VDOT also says to put both witness and hold points "where critical characteristics are to be measured and maintained, and at points where it is nearly impossible to determine the adequacy of either materials or workmanship once work proceeds past this point" (§5.14.1).

Hold point vs witness point: the hold blocks the next step until someone verifies and releases it. The witness requires notice; the next step may proceed after that notice unless the contract says otherwise.

How do hold points and witness points appear in an ITP?

On an inspection and test plan, each line is a test or inspection. The hold / witness / review column tells the field what happens at that line. The US federal guide spec UFGS 01 45 00 does not mandate those three letters, but it does require a Testing Plan and Log that names each test, the feature of work, the spec paragraph, the frequency, and the person responsible (UFGS 01 45 00). Teams add H / W / R so the plan also shows who must stop, who must be invited, and who only reviews the record.

ITP columnWhat to write for a hold or witness
Spec section and paragraphThe sentence that creates the stop or the notice
Feature of workThe crew or system that cannot cover the work yet
Inspection / testWhat must be seen or tested
Hold / witness / reviewHold, Witness, or Review
Responsible partyWho inspects, who is notified, who releases
RecordThe report, ticket, or sign-off that proves the line

A concrete example from the ITP template: reinforcement placement is a hold before concrete; slump, air, and cylinder sampling is a witness at placement; compressive-strength results are a review of the lab report.

Special-inspection lines from the Statement of Special Inspections should appear on the same plan. IBC Table 1705.3, for example, makes reinforcement placement periodic and fresh-concrete sampling continuous (IBC 2024 §1705.3). Continuous special inspection is not the same label as a hold point, but it is often scheduled as one: the inspector has to be present, so the pour does not start until they are.

How do you notify and release a hold point?

Notification. The plan should name who is notified, how, and how far in advance. Published examples:

SourceNotice rule
VDOT QA/QC §5.15The quality-assurance manager names a primary contact (and an alternate). The time needed to respond is written into the QA/QC plan and the schedule. Where the owner attends, that party answers with written reports or releases.
UFGS 01 45 00 §1.8Notify the contracting officer at least two business days before each preparatory-phase meeting and each initial-phase inspection.
NYC Building Code §1704.1.1.3The permit holder gives special inspectors or agencies at least 72 hours' written notice before work requiring special inspection starts, and gives them the current approved documents (NYC BC 2022).

Release. VDOT §5.15.1 treats the owner's written report or release as the document that lets work continue. On a private job the release is whatever the contract names: a signed inspection report, a hold-point ticket, or an entry in the ITP log. Do not treat a calendar invite, a text, or an unconfirmed report as a release unless the contract says so.

UFGS also tells the QC manager to record, on the Testing Plan and Log, the date each test was performed and the date the results were forwarded (UFGS 01 45 00 §1.12.6). That log line is the usual proof that a hold or witness was closed.

What happens when a hold point is missed?

A missed hold point means work went past the stop without the required verification, or the verification record is dated after the work that should have waited.

Under the IBC, covering work before the special inspection or test is complete breaks §1704.2.2. The work was supposed to stay accessible. The building official can require it to be exposed again so the inspection can still be done (IBC 2024 §1704.2.2).

Under VDOT's published rule, the owner may direct the contractor, before final acceptance, to "remove or uncover such portions of the finished Work as may be directed," then restore them. If the exposed work is acceptable, the contractor may seek a price and time adjustment. If it is not, the uncovering and repair are at the contractor's expense (VDOT QA/QC Minimum Requirements §5.11.4).

On the quality file, keep the miss visible. Do not overwrite the empty hold with a later passing report. Record the date work proceeded, the date any report arrived, whether the work was uncovered, and the disposition. Failed tests stay next to the passing retest; a late hold stays next to the release that eventually arrived. See matching reports to the Statement of Special Inspections.

How SpecProven flags a missed hold point

SpecProven puts hold, witness, and review on each plan line. After reports are matched to those lines, missed hold points are flagged when no report is matched, or a report is dated after work that should have waited (how it works). SpecProven does not send the official notice to the building official or file a city form. The contractor still gives the notice the code or contract requires.

A paid pilot is $2,900 to start and covers four projects, then $500 per project per month after the four included. Pricing.

FAQ

What is a hold point?

A hold point is a mandatory verification stop. Work does not proceed past it until the named inspection or test is complete and released (VDOT QA/QC Minimum Requirements §5.14.1).

What is a witness point?

A witness point is a notice point. The named party is invited to observe the work or test. After proper notification, work may continue even if that party does not attend, unless the contract also requires a design-team certification (VDOT QA/QC Minimum Requirements §5.14.1).

What is the difference between a hold point and a witness point?

The hold blocks the next step until verification and release. The witness requires notice; the next step may proceed after that notice. Both belong on the inspection and test plan, at steps that become hard to check once they are covered (VDOT §5.14.1).

How do hold points appear in an inspection and test plan?

Each ITP line that is a stop is marked Hold, with the spec paragraph, the feature of work, the responsible party, and the record that will release it. Witness and review use the same columns. See the ITP guide and template.

How do you release a hold point?

Give the notice the contract or code requires, complete the inspection or test, and keep the written release or report on that plan line. VDOT treats the owner's written report or release as the document that lets work continue (§5.15.1). UFGS records the test date and the date results were forwarded on the Testing Plan and Log (UFGS 01 45 00 §1.12.6).

What happens if a hold point is missed?

The work that should have waited may have to be uncovered so the inspection can still be done (IBC 2024 §1704.2.2; VDOT §5.11.4). Keep the miss on the log next to any later report. SpecProven flags a hold when no report is matched, or a report is dated after work that should have waited.
