Background
Sample project — not a client commission. Produced by BuildPixel Studio, the Upwork agency I run with a web developer partner. A single-storey house (≈70 m² net) modelled as an open-BIM IFC4 file, then documented directly from the model: walls with typed layer build-ups (IfcMaterialLayerSet), doors, windows, openings, slabs, roof and IfcSpaces; property sets (Pset_WallCommon, Pset_DoorCommon, Pset_WindowCommon…) and Qto base quantities; plan and section sheets generated from the IFC; quantity take-off exported to spreadsheet. IFC4 file validated with 0 schema errors.
