Measured Takeoff
Measured takeoff (planning-grade)
Envelope- and convention-based home takeoff: envelope/wall/roof/opening/drywall categories from the declared plan envelope; lot area measured from the lot polygon when present. Framing = plane areas. Elevations and options carry no geometry → honestly absent.
| Category | Quantity | Unit | Basis |
|---|---|---|---|
| Windows | 12 | ea | assumed |
| Exterior man doors | 3 | ea | assumed |
| Overhead (garage) doors | 1 | ea | assumed |
| Total opening area | 319 | sf | assumed |
| Envelope footprint | 3,456 | sf | derived |
| Foundation slab | 3,456 | sf | assumed |
| Exterior wall perimeter (per plate) | 240 | lf | derived |
| Exterior wall length (all plates) | 480 | lf | derived |
| Gross exterior wall area | 5,040 | sf | assumed |
| Wall framing area (plane) | 5,040 | sf | assumed |
| Siding (net of openings) | 4,721 | sf | assumed |
| Exterior wall drywall (net of openings) | 4,721 | sf | assumed |
| Roof area | 3,863.8 | sf | assumed |
| Roof framing area (plane) | 3,863.8 | sf | assumed |
| Conditioned floor area | 2,200 | sf | derived |
| Ceiling drywall | 2,200 | sf | derived |
| Interior partition drywall | 4,400 | sf | assumed |
| Elevated floor framing area (plane) | 1,100 | sf | derived |
| Lot area | 10,830 | sf | measured |
Envelope divergence. Gross envelope vs finished area: envelope footprint (3456 sf) is 3.14x the implied finished footprint (1100 sf = 2200 sf / 2 stories). The 25% threshold is an exact-footprint sanity check; envelope-basis quantities (slab, walls, roof) remain a declared upper bound, not a measured home - surfaced, never averaged away.
Assumptions
- openingSchedule: SFD_OPENING_CONVENTION — Declared schematic opening convention (2/bed + 4 common windows; front/rear/garage-house man doors; overhead per garage type) — not a door/window schedule.
- foundationType: slab_on_grade — Slab-on-grade; no footings, thickening, or slab thickness modeled.
- floorToFloorFt: 10.5 — STORY_HEIGHT_FT (scheme-model3d.mjs) — the massing convention shared with 3D so takeoff and massing never disagree; not a designed section.
- roofPitch: 6:12 — SFD_ROOF_PITCH 6:12 -> plan slope factor 1.118; pitch is not modeled on catalog plans.
- partitionDrywallFactor: 2 — Both faces of interior partitions over conditioned area; declared factor, not a measured partition takeoff.
This is planning-grade, not bid-level output.
- Planning-grade, not bid-grade: NOT purchasable, bid-level, or distributor-quote output — no SKUs, no waste factors, no supplier mapping (full-product-requirements.md §2.9).
- Framing quantities are PLANE AREAS, not member counts or structural design.
- Openings are a DECLARED schematic convention, not a door/window schedule; catalog-plan quantities are envelope- and convention-based, declared per quantity.
- Moves NO money: line items, contingency/escalation, summaries, exports, and CSV columns are byte-identical.
- Not a quantity survey, appraisal, or permit determination; drawings remain non-permit-ready.
The cockpit dock TAKEOFF group (scheme-level measured quantities on the Site Studio) is staged for v1.1. The live scheme takeoff is already available to agents and operators through the guarded scheme API.
Material Schedule
Material schedule (planning-grade)
Quote-ready material lines mapped from the measured takeoff and the org material catalog. Base is the converted takeoff quantity; waste is shown as its own component; purchase is base plus waste. Cost bases are the builder’s manual planning figures and are margin-visible only.
