Quality Control on Site

Quality control is the day-to-day inspection rhythm that catches drift early. QBFS runs construction quality control on Australian residential, multi-residential, and commercial projects — site-based inspection against ITP hold-points, with conformance recorded, non-conformance escalated, and a defensible written record produced as the build progresses. The work pairs naturally with the QA compliance pillar: QA designs the rulebook, QC inspects against it.

What's Inside

What construction quality control covers

A QC engagement typically covers:


Hold-point inspections
— each ITP names hold-points, such as waterproofing membrane before tiling, structural reinforcement before pour, or fire and acoustic separation before close-up. QBFS attends these inspections and records conformance.


Witness-point oversight
— for lower-risk inspections that don't strictly require independent verification but benefit from a senior eye, QBFS attends as a witness.


Sample testing oversight
— where the ITP calls for sample testing such as concrete cylinders, soil compaction, or water tightness, QBFS reviews the test method, witnesses where required, and integrates the test result into the conformance record.


Non-conformance escalation
— when inspection reveals work that doesn't meet specification, QBFS issues an NCR with photographs, references, and a path to close-out.


Trade conformance evidence review
— each trade is supposed to keep its own conformance evidence such as mill certificates, install certs, and photographs. QBFS reviews these as part of the inspection workflow.

Document trail update — each inspection is logged in the QA system with date, scope, findings, and sign-off.

Why It Matters

Why hold-point QC matters

Cover-up is binary — once work is covered, such as waterproofing under tile, reinforcement in concrete, or services in plasterboard, verifying conformance becomes expensive or impossible. Hold-point inspections are the last cheap opportunity.


Sub-contractor accountability
— trades who know an independent QC inspector is attending hold-points perform to the spec. Trades who don't see independent QC sometimes don't.


Insurance and dispute position
— a documented hold-point QC record is one of the strongest defences a builder has if the work is later questioned. The record proves the inspection happened, what was found, and what was rectified.

When to Engage

How QC engagements run

Full QC delivery — QBFS runs the entire QC rhythm on the project, attending every named hold-point, issuing conformance records, and escalating non-conformance. Used when the builder doesn't have an in-house QA team.


High-risk QC delivery
— QBFS attends the high-risk hold-points only, such as waterproofing, structure, fire and acoustic separation, and services penetrations. The builder's own team handles lower-risk QC.


QC oversight
— the builder's own team runs QC; QBFS audits a sample of the QC work to confirm it's being done properly. Used by larger builders with established QA teams.


The structure gets sized at engagement.

How it Runs

What QC isn't

Not certification — statutory certification stays with the appointed certifier; QC inspections inform but don't replace formal sign-offs.

Not supervision — QC observes and records; trade supervision stays with the head contractor's site team.

Not commercial sign-off — QC is technical; commercial milestones such as progress payments and variation approval sit elsewhere.

The clean separation keeps the QC record independent and defensible.

QC across Australia

QC engagements are delivered nationally with site work coordinated wherever the project sits. Most active engagements are in Queensland and northern NSW where site visit logistics keep hold-point frequency feasible. Commercial work in other states runs with travel built into the engagement scope.

Start With a Call

Tell Paul the project. The next step gets sorted on the call.

Best way to start is a phone call. Tell Paul the project, the issue, where you sit in the build cycle. The next step gets sorted on the call: site visit, desktop review, or a referral if QBFS isn't the right fit.
Frequently Asked Questions

Common questions, answered.

  • What's the difference between QC and a building inspection?

    A building inspection is a one-time survey of the property at a moment in time. Quality control is an ongoing inspection rhythm against an Inspection Test Plan, with conformance recorded at each hold-point through the build. The two have different scopes, different deliverables, and different price points.

  • How frequently does the QC inspector attend site?

    Frequency is set by the project’s hold-points, not by the calendar. A multi-residential build at substructure stage might trigger several hold-point inspections in a single week; a slower-moving commercial fit-out might run weeks between hold-points. The schedule is driven by the ITP.

  • Can you cover just the high-risk trades?

    Yes. Most builders engage QC for the high-risk hold-points and run their own QC on lower-risk work. The scope is set at engagement.

  • What happens when QC finds a non-conformance?

    The NCR is issued to the head contractor with photographs, references to the contract or Australian Standard the work doesn’t meet, and a recommended close-out path. The trade returns to address the NCR, QBFS verifies the close-out, and the record is updated. Where the trade disputes the NCR, the matter usually resolves through technical discussion; where it doesn’t, the head contractor decides next steps.

  • Will QC reports support a future dispute?

    Yes. A documented QC record is a strong evidence base for any post-handover matter. Reports are written with that potential use in mind.

  • Does QC overlap with sub-contractor audits?

    There’s overlap. QC is the inspection rhythm against hold-points; sub-contractor audits are deeper periodic reviews of a trade’s overall output. Most engagements have both inside a single QA framework.

  • What does QC cost?

    The fee scales with hold-point frequency, project size, and scope, whether full QC, high-risk only, or oversight. Call Paul on 0407 146 737 to scope an engagement.
