Leveret Systems Agentic BIM Service

Leveret Systems is a UK-based agentic AI engineering consultancy that builds the live layer between federated BIM models and the contract documents that surround them — programme, procurement, cost plans, specifications and standards. The service quantifies a federated Revit or IFC model end-to-end, classifies every element against project context, and produces a continuously refreshable view that downstream cost planning, programme risk analysis and compliance audit can read as a function rather than a static export.

The architecture is hybrid by design. Deterministic rules narrow the work before any AI reasoning is applied — the cheap, fast, predictable layer carries the bulk of the classification, and reasoning models handle only the ambiguous tail. Schemas reject malformed answers at the boundary, citations are enforced as code, and items the agent cannot confidently resolve route to a tightly-scoped human review queue rather than being silently committed. In a domain where every line of a Bill of Quantities must be defensible, that abstention behaviour is the safety feature.

Each engagement contributes to a project-by-project knowledge layer that accumulates across the lifecycle. Subsequent runs converge faster as the layer learns the project's specific Activity DataBase codes, NRM2 mappings, supplier patterns and specification conventions. Within a single project we already observe roughly a third of elements resolving from the knowledge layer alone on rerun, without firing the agentic stack at all. The same effect is designed to compound across engagements.

The service integrates with existing tools rather than replacing them. Revit and IFC models are ingested through Autodesk Platform Services. Contract programmes parse from Primavera P6 exports or revision-tracking spreadsheets. Procurement schedules in NEC, JCT or bespoke layouts reconcile against the model. Specification PDFs are indexed for retrieval-augmented review. The Monte Carlo input layer — activity duration distributions, supplier lead-time distributions, element-to-activity links — is structured as live data, so a critical-path kernel reads it as a function and produces P50, P80 and P95 completion windows with a tornado attributing slip to specific suppliers.

Leveret Systems delivers in two engagement modes. Per-project engagements (one to three weeks) suit teams who need a single model quantified, reconciled and structured for risk and cost analysis on a specific job. Strategic embedded engagements (four to six months) suit organisations who want the service tuned to their tools and embedded in their permanent delivery capability. The code, the architecture and a clone of the cross-project knowledge layer transfer with the strategic engagement. We are not a platform vendor; we do not replace your QS, planner or BIM manager. We give them back the week of every month they currently spend reconciling documents that ought to have been reconciled already.
