Coverage Gate
Each mandatory check carries its own capability, evaluation and evidence state. A “ready” verdict is structurally impossible while any required row is uncovered — the tool cannot silently skip a rule.
Audit engine live in production — not a mock-up
Compliance is
a build step.
Every IFC version checked automatically — the way software teams run tests before a release. Applicant-side, IFC-native, and every verdict carries its own evidence.

Illustrative run against the Swedish rule pack in development. Today the engine runs in production on Russian design documentation.
01 — Problem
Code compliance is where
building projects stall.
The check is manual, the codes move faster than the engineers, and the cost lands on the applicant.

03 — 3D Spatial Audit
IFC Geometry & Real-Time
Scanning Plane.
Inspect building geometry in 3D. The automated scanner plane passes through structural, architectural, and MEP layers, continuously validating compliance rules against IFC entity attributes.

From raw architectural CAD and IFC geometry to correlated rule execution. Every finding connects back to its precise source in the model.

Cross-Domain Join Engine
Types joins across architecture, structural engineering, and MEP routing. Finds clashes and code violations before construction starts.
05 — Solution
Continuous integration
for buildings.
Two mechanisms make the verdict trustworthy. Both are patent pending.
Proof-carrying correlation
Cross-domain findings are typed joins over IFC entities with a provenance trail back to source facts — so a finding can be re-derived, not just trusted.
Bitemporal source closure
Codes move: national, state and municipal amendments land continuously. Any past review can be replayed against the rules as they stood on the submission date.

The category tipped.
Penetration is still ~2%.
Capital and regulation arrived in 2026; the installed base did not. That gap is the entry window.

Everyone owns one column.
Nobody owns the row.
“Upload a PDF and let AI find code violations” is a crowded lane. Neutral IFC plus jurisdiction replay is not.

Fragmentation is the moat — there is no single global building code, and that is exactly why a jurisdiction-replay engine compounds.

The engine runs today on real, paid project documentation. The Swedish rule pack — BBR (Boverkets byggregler, the Swedish building regulations) and PBL (Plan- och bygglagen, the Planning and Building Act) — is the first Western target; DACH and US follow.
