TerraFab OS — the evidence platform built for Australia's modular and prefabricated building reforms.
Modular, prefabricated and offsite construction is moving into a far more evidence-heavy environment. Manufacturer declarations, traceable supply chains, documented compliance and records that survive audit are becoming the standard — and most of that work happens in a factory offshore, months before anyone in Australia sees the building. TerraFab OS is the operating system for that sequence: it captures inspections, photos, certificates and sign-offs as they happen, holds them in one timestamped, audit-logged project record, and gives each authorised party the view they need — builders see hold points, manufacturers see what they must declare, certifiers see requirement-mapped compliance, lenders see the evidence behind claimed progress. One structured evidence trail a certifier or auditor can reconstruct.

The shift
Housing is moving toward industrialised construction — built in a factory, to a repeatable process, at a pace site-by-site building cannot match. Governments are supporting wider adoption of Modern Methods of Construction to lift supply and productivity. But delivering faster only builds confidence if the evidence keeps pace: approvals, inspections and quality assurance still have to be demonstrable, project by project and module by module.
TerraFab OS is a digital governance platform for industrialised and offsite construction. It captures approvals, inspections, quality assurance, certifications and manufacturing evidence as a digital chain of custody — from design approval through to project completion — so developers, lenders, certifiers and government can review the same underlying evidence trail, with role-appropriate views.
The problem
90%+
of your building is finished before anyone in Australia sees it. Between the factory gate and your site sits a $-millions visibility gap — and it's yours to carry.
What's actually been built?
Progress photos from the factory are not proof of progress.
Were the approved materials used?
The steel you specified and the steel installed can be two different things.
Does it meet Australian standards?
NCC and AS/NZS compliance has to be evidenced during manufacture — not retrofitted.
Can you demonstrate it, later?
Declarations, approvals and progress claims all rest on evidence someone has to produce on request — long after the factory has moved on.
The chain of custody
Each gate has to be cleared in the record before the next one opens. Every gate carries the evidence that cleared it, the person who signed it, and the timestamp — recorded against the module.
01 · DESIGN FREEZE + APPROVAL
Drawings and specifications are frozen, and the approval your project runs under is confirmed with the certifier — whichever instrument applies in your jurisdiction as the reforms take effect. Every later piece of evidence is checked against this baseline.
02 · FACTORY PRODUCTION
Factory teams record photos, materials and test results as modules move down the line — timestamped as they are submitted, not written up later.
03 · HOLD POINT — THE RECORD WAITS HERE
Hold points cannot be cleared by the factory in TerraFab OS, and the platform will not record an approval without evidence attached — so the decision rests on the evidence in front of it.
04 · SHIPMENT + HANDOVER PACK
Approval-pack exports, the full custody log and a point-in-time snapshot are delivered with the modules — your compliance evidence, your warranty baseline and the evidence a lender's close-out review needs, in one file.
What the record holds
Structural frame, services, waterproofing — timestamped on submission.
ISO, QMS, material certs and worker qualifications recorded against the approved spec.
Hold points, witness points and test reports in a defined sequence.
Non-conformances with disposition, rework and documented close-out.
Inspection footage and factory walkthroughs tied to each module.
Why now
Australia is moving toward a more consistent national approach to modular and prefabricated construction. The detail and the timing differ by jurisdiction, and much of it is still being implemented — but the direction is settled: more documentation, traceable supply chains, clearer accountability, and digital evidence that has to hold up long after handover. TerraFab OS is built to carry that load as it arrives, not to explain it.
What a manufacturer states about a module has to be backed by the production record behind it. TerraFab OS holds that record — inspections, materials, quality assurance records and sign-offs — attached to the specific module being declared.
Installation and assembly documentation travels with the modules rather than arriving separately. Instructions, revisions and the drawings they match sit in the same record as the evidence of manufacture.
Approval pathways are changing, and requirements vary by state. TerraFab maps whichever obligations apply to your project onto specific hold points, so evidence is gathered against them during manufacture — evidence-based compliance, not reconstructed afterwards.
NCC and AS/NZS obligations are tied to the inspection that proves them. Every requirement can be traced to the photo, certificate or test result that satisfies it, to the hold point it cleared, and to the person who signed it off.
Mill certificates, batch numbers and supplier documents are recorded against the approved specification and traced to the modules they went into. Substitutions can be raised for review in the record before they are accepted.
Certification decisions stay with the project's own independent certifier, who is independent of both the factory and TerraFab. TerraFab OS puts requirement-mapped evidence in front of them — it never makes the call, and it supplies no certifier.
The project record is retained for the life of the building, not the life of the project — a certification history rather than a closing folder. Timestamped, audit-logged, and reconstructable by a certifier or auditor years later.
TerraFab OS is compliance infrastructure, not legal advice. Your certifier and your legal advisers determine what applies to your project.
One evidence regime
Software alone doesn't make a factory honest — but it does decide what has to be shown, and to whom. TerraFab OS helps project teams capture, organise and review evidence across offsite manufacturing and delivery: hold points and witness points defined up front, material certificates recorded against the approved spec, and certification decisions left with the project's own independent certifier. The governance model travels with the process rather than the postcode, so the same hold points, evidence rules and quality assurance records apply wherever a facility is located.
Hold points cannot be cleared by the factory in TerraFab OS — and no approval is recorded without evidence attached.
Steel, insulation and fixings recorded against the approved specifications for the project.
Entries are timestamped, and changes leave a visible trail in the custody log.
Why TerraFab
Australia is adopting industrialised construction as a mainstream delivery model. Faster approvals alone do not create confidence — developers, certifiers, financiers and government still need evidence that a module was manufactured, inspected and delivered against approved documentation. TerraFab OS is where that evidence is captured, structured and reviewed.
A mobile capture shell for the factory floor, so records are entered at the workstation rather than reconstructed from a desk.
Hold-point decisions sit with the project's own certifier, independent of the factory and of TerraFab. The platform organises the evidence; it makes no call and supplies no certifier.
Obligations are tied to the inspection that evidences them, so gaps are visible during manufacture rather than at handover.
One continuous record from design freeze to site, keeping what was recorded alongside the module it belongs to.
Evidence arrives organised the way a certifier assesses it, not as a folder of photographs.
Certifier-assessed progress evidence, exported in a form a credit team can audit and question.
Retained for the life of the building. Timestamped on submission; edits leave a visible trail.
Serial-level traceability means a question about one module has one answer, not a project-wide search.
Manufacturers
Manufacturer declarations, installation instructions, supply-chain documentation and serial-level traceability, captured as you build. What you declare is backed by the production record for that module — audit-ready, not assembled in a hurry afterwards.
Builders & GCs
Documented evidence of how each module was built — before it reaches your crane. No opening walls on site to find out what happened in the factory.
Certifiers
Requirement-mapped evidence reviewed during manufacture, with a documented trail behind each decision. Independent throughout — TerraFab OS organises the evidence and never the conclusion.
Developers
Follow your capital becoming buildings. Evidenced milestones mean fewer surprises, a clearer compliance position and a project record you can put in front of a board, certifier or lender.
Lenders & financiers
Certifier-assessed manufacturing progress, requirement-mapped evidence and audit-ready documentation — so milestone reviews and due diligence rest on recorded evidence rather than assertion. TerraFab improves the information; it provides no finance and makes no decision.
Architects
Confirm approved designs and specified materials are followed on the production line, with photographic evidence tied to each drawing revision.
Councils & government
Structured, certifier-reviewed construction records for government housing delivery, housing authorities, community housing and institutional housing providers — and for public procurement teams who need transparency and accountability on factory-built projects.
