Building tools

Use reviewed tools to prepare scope, questions, documents and quote comparison more clearly.

Tools for preparation and comparison

A Costavy tool organises information; it does not replace measurement, diagnosis, calculation, quotation or professional advice. Every result must show its inputs, assumptions and boundaries.

Only tools with an assigned owner, review date, tested calculation and suitable disclaimer may be presented as available.

Publication gate for each tool

clearly defined purpose and supported situations
minimal input without unnecessary personal data
repeatable calculation or decision logic with tests
visible assumptions, units and rounding
technical, legal and safety boundaries
owner and date for periodic review
