Planning-grade model; IFC is not construction BIM.
Compares declared finished plan square footage against the schematic gross envelope floor area (footprint x stories, garage excluded). This is the same gross envelope vs finished story as the measured-takeoff reconciliation: it is advisory and moves no money. Ratio 1x is below the seeded placeholder band but still physically possible; treat it as calibrated or more detailed plan dimensions, not a pricing disagreement.
Schematic-envelope quantities derived from the plan's box — advisory, not measured construction takeoffs.
Quantities only — no pricing on this surface.
Planning-grade facade cladding areas from the rendered primary mass's vertical shell faces, grouped by the same north/south/east/west model-coordinate facing axes used by elevation export. These are elevation facings, not semantic front/right/rear/left labels or geographic bearings without a geo-anchor. No designed facade openings with usable dimensions are present, so only gross face areas are reported; no zero opening deduction or net area is invented. Attached garages and wings, gable triangles, foundation skirts, roof/parapet surfaces, trim, material system selection, and waste are excluded. Quantities only — not a measured construction takeoff. wall height assumed 2 stories × 10.5 ft; plan height fields absent.
