Why this exists

Construction information is fragmented across BIM models, drawings, schedules and visual project context. A chat-only architecture can hide provenance or hallucinate facts. This workbench keeps natural language as the interaction layer while controlled domain execution remains the factual layer.

Core distinction. LLMs interpret intent. Deterministic domain tools calculate engineering facts.

Architecture

Natural languageTyped planningCapability gateDomain toolsEvidenceVerificationAudit trail

The public repository uses a shared typed QueryPlan contract for deterministic and bounded semantic planning. Capability gates reject unsupported operations before tools run. Python and IfcOpenShell compute bounded BIM facts; visual models interpret drawing or viewer pixels without replacing structured IFC computation.

Key capabilities

Hybrid planning

Rules and a bounded semantic planner produce the same typed plan contract.

Capability gating

Unsupported operations are rejected before controlled tools execute.

Deterministic BIM computation

Python and IfcOpenShell handle counts, grouping and bounded height extrema.

Multimodal context

Engineering drawings and current-view snapshots remain explicit source modes.

Evidence-backed answers

Results carry IFC identities, PDF pages, regions or other source locators.

Independent verification

Answer shape, evidence presence and dispositions are checked before presentation.

Inspectable audit trail

Planning, execution, verification and final response stages remain traceable.

Implementation evidence

The screenshots below are from the public repository's synthetic fixtures. They show the workbench as an inspectable reference implementation, not a hosted product or production service.

Current scope and maturity

This is a public ARMIE AI Labs reference implementation with one active local project workspace, a bounded BIM query surface, synthetic BIM/PDF fixtures and multimodal viewer/drawing workflows. It is not production SaaS, a hosted enterprise product, a compliance engine, a multi-tenant platform or an unrestricted BIM reasoning system.

The workbench does not claim large-scale throughput, autonomous geometry exploration, arbitrary property language, cross-source joins or perfect visual correctness. Those boundaries are part of the system's public evidence standard.

Related infrastructure

Retrieval infrastructure and vertical execution share a discipline, not a claimed unified platform.
