Construction takeoff software — accurate quantities, automatically
SangoImmo computes the takeoff from the model: wall and floor areas, concrete volumes, ring-beam lengths, opening counts, bags of cement, roofing sheets, rebar. No more scribbled takeoffs and costly omissions. Open SangoImmo →
Takeoff with no copy errors
Every drawn element feeds the quantities. Openings are deducted from wall areas, discrete quantities (doors, bags, sheets) are rounded to whole units. You get a coherent, traceable takeoff you can check line by line in the schedules (by floor, structure, roof).
From quantities to purchase
The takeoff turns directly into a buy list (bill of quantities): what to buy, in whole units, at local prices. No more guessing how many bags of cement to order — the app says so, and exports it as CSV.
Built for the African site
Line items reflect building here: cement block and earth brick, slab and ring beam, septic tank, water tower, meter. Costing rules (SANS 10400, DTU, CEMAC practice) are built in so the quantities hold up.
Frequently asked questions
- What is takeoff software?
- Takeoff software computes the quantities of materials and works in a project (areas, volumes, lengths, counts). SangoImmo does it automatically from the 3D model, then derives a buy list and a quote.
- Does the takeoff deduct openings?
- Yes. Wall areas are computed by deducting doors and windows, and discrete quantities are rounded to whole units to match the real order.
- Can I export the quantities?
- Yes, as a buy list (bill of quantities) and CSV, at local prices, so you can order with no re-keying.
