What this skill does
Material Passports & Circular Construction (2026) Why it matters The EU Taxonomy and CSRD push construction toward circularity: buildings must be designed for disassembly, materials traceable for reuse. A material passport is a digital record of what is in a building, where, and how it can be reused at end of life. What a passport contains Per element (or per BOQ line): Field Source --- --- material & volume/mass BOQ components[] (resourcename, resourcequantity, resourceunit) location in the building BIM element link manufacturer / EPD procurement records recycled content % supplier declaration / EPD reuse potential at EOL disassembly class (reusable / recyclable / downcyclable / landfill) embodied carbon (A1–A3) embodied-carbon-esg skill Building the passport from DDC data Design-for-disassembly rules to encode 1. Prefer mechanical fixings over wet trades (plaster/glue) at interfaces. 2. Mark structural vs non-structural layers — non-structural is the reuse pool. 3. One material per composite where possible (separate insulation from structure). 4. Record as-built changes — the passport must match the building, not the drawing. Reporting Total mass per material family (concrete, steel, timber, glass, insulation…). % recyclable/reusable by mass (EU Taxonomy circularity KPI). Hazardous content register (asbestos-free declaration, formaldehyde, VOC).
