Project overview

Permit-approved set → quantities and units by trade, measured from your drawings. Code review lives in its own tab. Costs are estimates from your unit prices.

Concrete

slabs · footings · walls

Steel + rebar

–

beams + reinforcing

Soil to remove

–

loose yd³ · the quoted qty

Openings

windows · ext/int doors

Upload a floorplan

Choose a PDF. The app opens it, shows the sheets, reads any dimensions it can, and builds the takeoff. Scanned image PDFs can be viewed but not auto-measured yet — you enter the key dimensions and it calculates the rest.

Upload each discipline — drag a PDF onto its slot (or tap to browse). They all merge into one project; big files compress automatically.

Civil / Site — not a schedule count; site servicing is measured off the plans.

Drawings

The sheets Give Me The Cost read from the uploaded set. Click a sheet to view it. On the floor plan, coloured pins show exactly where code issues were found.

Your uploaded sheets appear on the Upload page. Full in-app sheet viewer is coming with saved projects.

Material takeoff

The app calculates the quantities from your drawing dimensions. You enter the unit cost for each material — the total = quantity × your price. Costs start blank on purpose.

▸ Standard assumptions the app falls back on (only when a value isn't on the drawing)

Slab thickness: suspended 8", basement 4", garage 4" (OBC 9.16 min 3–4")
Strip footing: 16"×8" (OBC 9.15 min width 250 mm / 10", min thickness 100 mm / 4")
Foundation wall: 8" / 6" ICF core, 8' height
Spacing: wall studs & floor joists 16" o.c.; roof trusses 24" o.c.
Waste factor: +10% on framing, sheathing & drywall
Drywall: ½" walls / ⅝" ceilings, 32 ft² per 4×8 sheet

Tags: drawing read/measured off the plans · std standard assumption · count you enter from schedules.

Pricing: concrete uses a supplier price list (cost per m³ by mix class) with standard estimating adjustments applied. Mapping: footings/walls/basement → 20 MPa no-air $133 · suspended slab → 30 MPa no-air $148 · garage → 35 MPa C-1 air $171 (nearest to the 32 spec). Rebar: 15M $1,800/t · 20M $2,100 · 25M $3,000 · 30M $3,000. Other materials carry RETAIL SEED prices (homedepot.ca / rona.ca — Lowe's Canada is now RONA) — verify or overwrite with your supplier rates. Excavation is left unpriced: subs quote per loose yd³ + machine day rates. Change ceiling height 9–25 ft to update stud lengths & counts.

▸ Concrete supplier price list (per m³, supply)

20 MPa NO AIR (20N200) — $133 | 25 MPa (25N200) — $138 | 30 MPa (30N200) — $148
35 MPa NO AIR (35N200) — $158 | 40 MPa (40N200) — $169 | 50 MPa (50N200) — $190
25 MPa F-2 4–7% air (25F200) — $148 | 30 MPa F-2 (30F200) — $158
35 MPa C-1 5–8% air (35X200) — $171 | 40 MPa C-1 (40X200) — $185 | 50 MPa C-1 (50X200) — $198

Supplier notes: Polar Mix discount −$8/m³; 2% off for 30-day prompt payment (not auto-applied — subtract from cost if it applies).

This is a large (Part 3) building. The checks on this tab are Ontario Part 9 HOUSE rules — they don't apply here, so they're hidden. Part 3 buildings are reviewed under Division B Part 3 by the design team and municipal examiner; a large-building code module is on the roadmap.

Ontario Building Code review

A real Part 9 check. Enter the value from the drawing for each item — it’s compared live against the actual OBC requirement. Blank = not checked yet.

14 real OBC Part 9 checks — egress 9.9.10, stairs 9.8.2/9.8.4, handrail 9.8.7, guards & window fall protection 9.8.8, ceiling 9.5.3, hallway 9.5.7, door 9.5.5, smoke/CO 9.10.19, safety glazing 9.7.2. Enter the value from the drawing; it checks live against the real threshold. Auto-reading these off a drawing is the Claude-vision step. Approval likelihood is capped at 99% \u2014 this tool can’t issue formal approvals; the final 1% and the official decision rest with your municipal plan examiner.

How much of each trade is measured off the drawings vs carried as an assumption — and the one thing that would raise it. Nothing reads 100%: this is a permit-stage read; final quantities firm up on the tender set. Visible to your account only.
