Build an IFC Operations Work Order BCF Dispatcher

Process property management maintenance requests against IFC spatial hierarchies using IfcOpenShell BCF modules. Construct standard BCF-XML action topics linking malfunctioning equipment to spatial locations.

Facility Operations Manager

Receive tenant work orders detailing localized building service issues.

Resolve affected spatial rooms and equipment identifiers against IFC model definitions.

Generate standard BCF issue payload with camera viewpoint guidance via IfcOpenShell bcf library.

Export BCF-XML archive ready for contractor dispatch and operations tracking.

Operations ticket UI with IFC spatial location picker, issue description, and BCF download button.

Author mock maintenance requests mapped to synthetic IFC building storeys and mechanical spaces. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Leverages the bcf library listed in IfcOpenShell documentation for reading and writing BCF-XML topics.

langgraph, python-bcf, fastapi. LangGraph manages stateful transitions between ticket ingestion, spatial IFC matching, and BCF generation. Local or cloud LLM with strong text extraction and structured JSON generation capability.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Generated BCF topic contains valid title, guid, priority, and spatial reference.

Work orders without matching equipment are assigned to building storey level with fallback note.

BCF payload structure validates against buildingSMART XML schema standards.

Simulates dispatch workflows; does not interact directly with live electrical or pressurized plumbing hardware. Use mock external writes. Require human review before any real deployment.
