Why this exists
What the industry certifies, where delivered models stand today, and what closing the gap involves.
Established first, because it is commonly misunderstood.
As BIM adoption matures, organisations are increasingly expected to move beyond proprietary BIM workflows towards more interoperable OpenBIM practices. This transition requires not only appropriate technologies, but also organisational readiness in areas such as governance, business processes, workforce capabilities, data management, and compliance with open standards.
However, there is currently no simple and practical way for organisations to objectively assess their readiness for OpenBIM implementation or to identify the capability gaps that should be addressed before embarking on this transition.
The problem statement — research proposal, 10 Aug 2026
That is what this toolkit is for, and the rest of this page is the evidence behind it.
BIM moved the industry from drawing to modelling, and the model became the record: geometry carrying data, coordinated across disciplines, outliving the project into operations. That part is settled. What is not settled is who owns the file format that record lives in.
A small number of vendors own practical BIM today. That bought real maturity, and it charged for it in ways that only surface later — formats one application fully understands and others approximate, licences that scale with headcount, and model data whose readability depends on keeping a subscription alive. The consideration is most acute for the asset owner: a building outlives the software that modelled it by decades.
It is therefore worth examining what Autodesk certifies about its own software.
buildingSMART certifications vs. local-authority compliance, any jurisdiction
| Certification | Export | Import |
|---|---|---|
| IFC4 Architectural Reference Exchange | ✓ | — |
| IFC4 Structural Reference Exchange | ✓ | — |
| IFC2x3 Coordination View 2.0 — Architecture | ✓ | ✓ |
| IFC2x3 Coordination View 2.0 — Structure | ✓ | ✓ |
| IFC2x3 Coordination View 2.0 — MEP | ✓ | ✓ |
| Local-authority building compliance — any country | ✗ | ✗ |
The certifications cover interoperability — that files are imported and exported in accordance with the relevant IFC standard. They do not cover whether a building is lawful, which remains with the practice.
This is the correct division of responsibility rather than a gap in the product: local-authority compliance sits with the Appointing Party and the Lead Appointed Party. Software is never a legal party to it. No vendor holds certification for local-authority compliance in any jurisdiction; the category does not exist.
Since 1 July 2025, BIM has been mandatory for Malaysian government development projects valued at RM 10 million and above, under Ministry of Finance circular PK 1.15.1 Private-sector adoption is encouraged rather than required. CIDB publishes BIM guidance for project delivery separately from that circular.2
Other jurisdictions are on their own timetables. The United Kingdom required collaborative BIM Level 2 on centrally-funded public projects from April 2016.3 Singapore phases mandatory BIM e-submission by project size.4 The European Union’s public procurement directive is permissive rather than mandatory — it allows member states to require BIM tools for public works, but does not itself require them.5
This produces the situation the toolkit addresses: a specific deliverable is required, the software does not promise to produce it, and no established method measures the distance between the two.
Figures measured from delivered models, with the building named in each case.
Past a 4 GB boundary during export, geometry generation stops. There is no crash and no error message; the file opens and renders.
Elements delivered vs. elements silently absent
When a model is extracted into a database, the distribution of storage between geometry and semantics becomes measurable.

A measure of whether other tools can open the delivered file
Readiness is assessed across five dimensions, which vary independently.
The assessment scores each of governance, people and skills, technology, data and standards, and organisational processes on one shared capability ladder. The levels are the six capability levels defined by ISO/IEC 33020, the international standard for process capability measurement, which states it is applicable to any domain.6
They measure institutionalisation rather than individual initiative. A firm where one engineer exports IFC by hand sits at Performed: the practice occurs, but it is not planned, managed or maintained.
Not present, or it fails to achieve its purpose.
It happens and achieves its purpose, but unmanaged — through individual initiative.
Planned, controlled and maintained; the work products are kept.
A defined standard process, applied across projects rather than per person.
Measured quantitatively, so performance can be predicted rather than hoped for.
Those measurements drive continuous change to how the work is done.
Requirements differ by jurisdiction, so they are carried in versioned rule packs rather than embedded in the instrument. Coverage is partial; the current state is shown below.

The benchmark this toolkit builds
BIM maturity assessment is a crowded field, and this instrument should not be presented as entering an empty one. What follows is where it sits, and what it does not claim.
A 2020 evaluation by the Centre for Digital Built Britain with the UK BIM Alliance inventoried fifteen tools and six methods for assessing BIM maturity.7 At organisation level these include the BIM Excellence Online Platform, the NBIMS Capability Maturity Model, Penn State’s Organizational BIM Assessment, the Scottish Futures Trust’s BIM Compass, CPIx, and Succar’s BIM Maturity Matrix; at project level, Stanford’s VDC Scorecard and ARUP’s BIM Maturity Measure, among others.
That report found 45% of the organisations it surveyed who assess maturity had built their own internal tool rather than use a published one. It attributed this to specific failings it observed in the existing tools, quoted here in its own words: “rigid tools — one-size-fits-all; inaccurate and low granularity assessment; binary (yes/no) assessment focused on readiness and capabilities for compliance purposes; overlooking collaborative behaviour; inappropriate baselines and timing used in assessment.” The same report recorded interoperability and IFC support at 96% among the highest-rated areas of industry importance.
Assessing BIM capability against the ISO/IEC 33000 family of process-assessment standards is not a new idea, and this project does not claim it as one. BIM-CAREM, a reference model grounded on that same standard family, was developed at the Middle East Technical University and published in 2018.8 Its own review compares eight earlier models and concludes that “there is no commonly accepted and broadly used model in the literature”. Anyone assessing this instrument should read that work first.
Existing instruments treat interoperability as one topic among many — BIM-CAREM records it as “whether interoperable formats are used”, a question about presence. Here, all twenty criteria are about open-standard working, and the assessment reports nothing else.
Every instrument named above is self-assessment. This one optionally reads an IFC file you supply — inside your browser, never uploaded — and reports where the measurement disagrees with what you said. A claim and its evidence are reported as two different things.
This follows from a measurement rather than a preference. On one hospital model of 63,917 elements, 7.11% of elements carried a classification code and, of the codes present, none were invalid. The same model therefore scores 100% on validity and 7.11% on coverage. A one-word verdict is not merely coarse but arbitrary: it depends entirely on which of two independent axes it happens to measure.
Each criterion names the standard it is drawn from, the clause, and a tier recording whether the publisher’s own text was read, only a catalogue record, or only a secondary account. Sixteen of the twenty criteria are anchored to a published standard. Four are not, and say so. See the anchors and their tiers →
Two further differences are practical rather than methodological: the assessment is free, runs entirely in a browser with no account and no server, and takes about fifteen minutes — matching the fastest instrument in the 2020 survey; and the conversational step runs in whatever AI service you already use, so no key, no subscription and no data of yours reaches a model operated by this project.
The survey quoted above is dated February 2020 and the field has moved since. A tool published in 2026 by the author of BIM-CAREM was located but could not be obtained, and no claim is made about its contents.
No OpenBIM-specific instrument was found in the parts of that survey read, but it runs to several hundred pages and was read selectively. That is a gap not found, not a gap demonstrated, and it is recorded that way in the source register rather than presented as a claim to originality.
This is only a technical readiness assessment. It measures organisational readiness for open-standard working and the data quality of a model you supply. That is its entire scope. It says nothing about the lawfulness, safety, buildability or professional adequacy of anything you produce.
It qualifies nothing and no one. It confers no certification, accreditation, licence, approval or professional status. It is not evidence of compliance with any regulation, standard, code or contract, and must not be presented as such — to a client, an authority, an insurer, or in a tender.
Nothing here is audited or verified. The inputs are self-reported by the respondent and computed from a file the respondent supplied. No third party has witnessed, checked or attested to any of it.
Where regulation or an appointment requires a formal process, you must satisfy it separately. If your work requires insurance, professional indemnity, a licence, certification, or a formal qualification — under your regulations, your contract, or a client’s requirements — that’s yours to sort out directly with whoever requires it. This report substitutes for none of it, in whole or in part.
Measurement works. Certification does not. This toolkit can tell you how far a model and an organisation are from carrying compliant, open, well-structured information, with numbers you can reproduce. It cannot certify a model or a firm as compliant with any standard, code or authority requirement — and it will refuse to pretend otherwise.
No regulatory verdict is issued. Local-authority compliance rests with the Appointing Party and the Lead Appointed Party. No software is a legal party to it, and no BIM vendor holds such certification in any jurisdiction.
Coverage is not validity. A high score on well-formedness says the data present is correctly shaped. It says nothing about whether the right data is present. Both numbers are always reported together, and no single headline score is produced.
Self-reported answers are self-reported. Where measurements from your model contradict them, the measurement is used for scoring and the disagreement is shown to you.
Figures on this page are measured from named individual models or cited public sources, and are labelled as such. Single-building measurements are not industry statistics and must not be quoted as such. Nothing here is estimated, projected or illustrative.
Nothing here is insurance, indemnity or legal advice. Whether delivering on open standards affects your professional indemnity cover is a question for your insurer and your counsel, and this toolkit neither answers it nor is qualified to. Two facts are worth carrying into that conversation: warranty disclaimers are near-universal in software licensing, proprietary licences included; and professional indemnity insures the professional, not the tool. What an open-standard toolchain can evidence is technical conformance — schema validity, exchange fidelity, information completeness — and that is the only claim made here.

Research instrument, in development. This is a work in progress supporting academic research. Its criteria, thresholds and weightings are subject to expert validation and will change.
Where IT policy does not permit a model to be opened in a browser tab, the assessment can be run entirely offline.
The assessment is a set of static files with no server, no database and no accounts. It can be downloaded and opened from local disk — the same assessment and the same scoring, with no network involved at any point.
This applies where models are commercially sensitive, where the firm works air-gapped, where there is no connection on site, or where the organisation wishes to verify directly that nothing is transmitted. The archive is unzipped and opened directly, and the source is readable.
A single archive containing the assessment, this page, the rule packs, and a short README. Everything runs from file:// — no install, no build step, no dependencies to fetch.
