IFC / BIM ingestion
IFC semantic ingestion with IfcOpenShell, and a transparent fallback parser that labels its own reduced fidelity rather than hiding it.

Evidence-backed project reasoning.
Every answer is constructed from records you can open. Where evidence is missing, the Twin says so instead of producing a plausible sentence.
Every claim below is built from records, not retrieved text. Open one to see the source.
ASK TWINSAMPLE89% confidence
Roof Zone B is 4 days behind baseline and has consumed its float. Two causes account for most of the variance, and a third is adding to it.
Crane unavailability on 15 August cost a full shift of steel erection.
A partial connection-plate delivery on 16 August left the crew short of 42 units, with the balance not due until 24 August.
Rework on six under-torqued connections is adding an estimated 1.5 days.
The activity is now critical, with two successors exposed.
Why this confidence: Four independent records, three of them primary sources, all within the variance window. No contradicting evidence found.

CAPABILITIES
What the Twin holds.
3D Tiles & LOD streaming
IFC converted to GLB and 3D Tiles 1.1, with LOD0/1/2 and Cesium spatial streaming for models too large to load whole.
Distributed asset pipeline
Conversion runs as partitioned jobs with worker leases, cancel and resume, and a content-addressed cache that skips work already done.
4D schedule link
Activities bound to entities, with baseline, actual and forecast state per element, and an S-curve derived from the schedule itself.
Portfolio & comparison
A portfolio view across projects and a side-by-side comparison workspace, not just a single-project dashboard.
Verifiable audit trail
Observations, recommendations, approvals and executions written to a hash-chained log, with an endpoint that re-walks the chain and reports the first break.
Realtime & offline
Live project events over WebSocket with Redis fan-out across replicas, and a cached shell that keeps working offline, queueing comments until reconnect.
Evidence-backed reasoning
BM25 retrieval over project records, derived claims, verified citations, and an enforced downgrade when nothing matches.
Probabilistic forecast
P10/P50/P90 computed from measured activity slippage, each result reporting its model, sample size and calibration state.
