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.

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 counts what the drawing shows; it does not check the compliance of the installation and replaces neither the design nor the inspection.
Why Kotelys for this package.
One type per device
Optical detector, manual call point, water or CO₂ extinguisher: each has its marker, its colour and its total.
By floor or by zone
One zone per floor, detection zone or compartment, and the reports split the quantities.

Frequently asked questions
Another question? Write to us.
Is Kotelys suited to a fire safety contractor?
Yes, for quantities: devices counted symbol by symbol, cables and fire-rated walls measured, by floor. It does neither the design nor the regulatory check of the installation.
Does Kotelys recognise the symbols on the drawing?
No: you click each device. It is quick, and every quantity matches what you saw on the drawing.
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.
How much does Kotelys cost?
The beta is free, by invitation. The announced price is €24.90 excl. VAT per month per computer, with a one-month free trial.
