The same drawing, in Kotelys.

The take-off drawn on the drawing, the quantities sorted by type in the Objects panel, each in its colour.

Kotelys open on the sample drawing for the “strip-out and demolition” package: the take-off on the drawing, the quantities in the Objects panel.

What you measure, and how.

Three tools are enough: length, area and count. Each type keeps its colour, from the drawing to the report.

The volume of rubble, the bulking factor and waste sorting are then worked out in your estimate, from the Kotelys quantities.

Why Kotelys for this package.

  • The existing drawing is enough

    A PDF or an old scanned drawing: the scale is calibrated on a known dimension.

  • One zone per flat or per floor

    Every removal is split by zone in the reports, to phase the strip-out.

  • Existing and proposed in one file

    The existing drawing and the project drawings live in the same project, each with its types and reports.

Frequently asked questions

Another question? Write to us.

Is Kotelys suited to a strip-out or demolition contractor?

Yes, for quantities on the drawing: areas to remove, lengths and items, flat by flat. Asbestos and lead surveys remain those of the specialist reports.

Can you estimate a volume of rubble?

Kotelys gives the areas and, with a thickness, the solid volumes; the bulking factor is then applied in your estimate.

Does Kotelys open DWG files?

No: Kotelys works on PDFs and images, scanned drawings included. Print a DWG to PDF at scale from your viewer.

How do I get the quantities into my estimate?

The Excel export gives a summary and the object-by-object detail, as fixed values. The PDF take-off calculations write out every calculation, to attach to your pricing.
