Cost by element —
Click any element to expand its full take-off: geometry → reinforcement (each bar by diameter, with exact bars ÷ 12 m) → concrete materials by mix ratio → cost. Reinforcement detailing — anchorage, laps, hooks and end bends — follows EN 1992-1-1 (Eurocode 2) §8.3/§8.4/§8.7 (fyk 500, good bond, 100% lapped). Quantities are exact, not rounded to whole bars or lorries.
ElementConcreteUnitSteelCost
Elements subtotal — structure + walls (this level)—
This is a preliminary estimate — read before you budget

It prices what you have drawn and specified: substructure, the concrete frame, walls, plaster & paint, floor and ceiling finishes, doors and windows, the slab/floor build-up and any roofing you have added — plus your Labour, MEP, preliminaries and contingency allowances above. Quantities are computed exactly from the geometry; the money figure is only as good as the rates you set in the Rate library.

Not modelled (add an allowance, or price separately): detailed MEP design and fittings beyond the rough MEP % above, formwork & falsework, scaffolding, site preparation and wastage. Professional fees, permits & approvals, external & site works, furnishings and VAT/taxes can be entered in the project cost build-up below. Finishes and openings are only included for the rooms where you have actually applied them.

Files
Written as R12 ASCII DXF, the version every package still opens cleanly: AutoCAD, Revit, ProtaStructure, BricsCAD, QCAD. Walls come out as face lines, doors as a gap with a real swing arc, and dimensions and room names as text you can edit.

Bring in a drawing to trace over
No file chosen yet
Export a DXF or a PDF from AutoCAD, Revit, ProtaStructure or ArchiCAD and open it here. It is drawn underneath your plan at 1:1 in its own units; you set the drawing scale, place it, and trace over it. A PDF printed from CAD is read as lines you can snap to; a scanned PDF has no lines and comes in as a picture. DWG will not work (a closed binary format nothing can read in a browser), and a DXF of a 3D view arrives as loose triangles, so export a plan view.

3D appearance

Turn this on when you want the model to look real, for a client or a proposal. Leave it off while drawing: the plain view stays as fast as it is now, and 3D snapshots pick this up automatically.

Include
Document
Pages are numbered and every page repeats the project heading and the table head, so the printed bill reads as a proper document.
Excel workbook
The workbook carries a Rates sheet, one bill per level and a Summary that builds up labour, preliminaries, contingency, professional fees, permits, VAT and the grand total. Every amount and total is a live formula, so changing a rate or a percentage repriced the whole bill. Shaded cells are the ones meant to be edited.
The client name, job number, revision and status come from the plan sheet title block, so the bill and the drawings stay one set.

Sheet layout
The sheets carry the same title block as your plan sheets, so the client name, job number, revision and status stay consistent across the whole set. Change those in Plan sheets → page setup.

Levels to print
Prefix A-1 numbers the sheets A-101, A-102 and so on. Leave it empty for plain 1 / 2 / 3 numbering.

Leave a field empty to keep its default; the date defaults to the day of printing.

Extras
Your setup is remembered, so you can preview now and print later. In the print dialog keep margins at None and scale at 100%, then choose Save as PDF.

Name your project

Give your design a name so you can find it again later (max 100 characters). It becomes part of the project link, so pick one you’ll recognise.

Project levels

Each level's height is its floor-to-floor distance — and the default wall height when you draw on that level. Foundation is the depth below the ground datum (RL 0).

Rate library

Set the price per unit for each item (e.g. KSh per stone, per m³, per kg). These rates apply across all levels and drive every amount in the bill of quantities.
