Frequently asked questions
Another question? Write to us.
Is Kotelys suited to a site manager or a planning department?
Yes: the site layout plan is drawn to scale on the site plan, with cranes, site accommodation and signage, and the legend counts the installations. It replaces neither the lifting study nor the health and safety plan.
Does the legend build itself?
Yes: the legend lists every installation with its quantity (metres of fencing, site cabin modules…) and updates with each addition.
Can I reuse my layers from one site to the next?
Yes: save a plan's layers as a layer set (Welfare, Lifting, Traffic…), then recreate them in one click on the next plan, in this project or another.
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.
