Build an IFC Demolition Material Circularity Auditor

Inspect structural elements in architectural IFC files using IfcOpenShell to calculate salvageable timber and masonry quantities. Produce standardized circularity manifests for deconstruction contractors.

Demolition and Salvage Coordinator

Import an IFC model representing a commercial building planned for deconstruction.

Query IfcWall, IfcBeam, and IfcColumn elements to extract material layer data.

Calculate total component volumes and cross-reference material recyclability ratings.

Compile a deconstruction inventory manifest highlighting reusable elements.

Material recovery dashboard listing salvaged volume metrics, demolition sequencing recommendations, and download buttons.

Clone public IFC samples from the buildingSMART international model sample repository. Starter examples below are synthetic. They are not downloaded records.

IfcOpenShell Leverages IfcOpenShell Python to read material constituent sets and element quantities from structural entities.

haystack, ifcopenshell, pandas. Haystack provides document extraction pipelines and question-answering retrieval over architectural salvage specifications. Cloud-hosted general language model capable of parsing technical deconstruction documentation and circular economy criteria.

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.

Processes material layer thicknesses and calculates total wall and beam volumes.

Categorizes materials into direct reuse, recycling, or disposal streams.

Outputs a deconstruction recovery manifest with embodied carbon offset metrics.

Circularity estimates are indicative guidelines. Hazardous material abatement must be inspected on-site by certified personnel. Use mock external writes. Require human review before any real deployment.
