What you measure, and how.

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

Kotelys works out a simple volume (area × thickness). It does not calculate cut and fill from a ground model.

Why Kotelys for this package.

  • Large site plans stay smooth

    A big PDF site plan opens and pans without slowing down, even when it is packed with detail.

  • One zone per section

    Base contract, optional section, block: every quantity is broken down by zone in the reports.

  • The same drawing for the site layout

    On the measured site plan, also place the site fence, the accesses and the welfare facilities.

Frequently asked questions

Another question? Write to us.

Is Kotelys suited to an external works consultant or an earthworks contractor?

Yes, for quantities on the site plan: areas, lengths, counts and simple volumes, phase by phase. It does not replace road design software: no long sections, no cut-and-fill from a terrain model.

Can it calculate an earthworks volume?

Yes for a simple volume: an area given a thickness returns m³ (topsoil strip, capping layer, sub-base). Kotelys does not calculate cut and fill between existing ground and the design.

How do I keep the drainage networks apart?

Create one type per network (foul water, surface water, ducts…): each has its colour on the drawing and its own line in the reports. One layer per package if you like. For a sloping network, give the type its slope (in % or in degrees): Kotelys returns the real length and writes the calculation in the take-off calculations.

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.
