FAQ
Short answers to the most common questions. For anything else, write to us from the support page.
Are the tools free?
Yes. The public PRAXAO and BUILNORA tools are free, with no usage limit. The management features (quotes, invoices, accounting, sites) are in the account area.
Do I need an account to use a calculator?
No. The public calculators work without an account. An account lets you save your calculations, documents and sites.
Where are my calculations performed?
The public calculators compute in your browser with exact decimal arithmetic (no floating-point rounding errors on amounts).
What is BUILNORA?
BUILNORA is the set of PRAXAO tools dedicated to construction: concrete, block or brick walls, steel, screed, plaster, paint, tiles, stairs, excavation and partitions. It provides quantities, assumptions and estimated costs.
Do BUILNORA results replace a structural study?
No. They are estimating take-offs: they do not replace the study and validation of a structural engineer. The drawings illustrate your dimensions; they are not a structural validation.
How are waste and margins handled?
Each calculator shows its assumptions (waste margin, joints, overlaps, ratios) and lets you change them. A value the calculation does not provide is not displayed.
Which languages and currencies are available?
The site is available in French, English, Spanish, German, Italian, Portuguese and Arabic (right-to-left). Documents can be issued in the same languages. Supported currencies are MAD, AED, EUR, USD and GBP.
Is a price shown in a tool a quotation?
No. Prices are the ones you enter or indicative values; they are not a supplier quotation. Always confirm a quotation with the supplier.
