Tracing instead of typing
Import the building drawings, calibrate them once (two points on a known dimension), then trace: a partition wall becomes 7.4 linear metres the moment you draw it, a floor finish becomes 31 m², a radiator is one tap. Quantities are derived from the geometry, not from a tired thumb on a numeric keypad at 5 pm. The capture works offline, on a Windows tablet, with a stylus or a finger.
Weights you can defend
Every mass in the catalogue is traceable to a public source: a manufacturer datasheet, a standard, a published weighing. When a building owner, an auditor or one day a court asks where a tonnage comes from, the answer is a reference, not a shrug. Hazardous materials follow a strict doctrine: declared asbestos switches the whole assembly to the dangerous waste stream, automatically.
Reports that survive scrutiny
The report follows the structure of the French methodology standard XP X46-039: documented mission framing, visited and non-visited areas with reasons, quantities with explicit calculation methods, deviations declared and justified, and location plans of the reusable products as annexes, with an explicit legend on every plan. Regulatory exports (national platform CSV, official forms) come out of the same data, built to match the official import specifications.
Built in France, designed for what Europe prepares
The capture engine is jurisdiction-neutral: calibrated drawings, traced quantities, sourced masses, waste stream routing. The French outputs (CSTB platform CSV, CERFA forms, national nomenclature) are plugins on top of that engine. When the EU pre-demolition audit arrives with its own formats, the engine will already speak the language; only the last kilometre changes.
See it on a real drawing
The rest (the catalogue depth, the reuse scenario, the analogy zones for partially occupied buildings) is best seen live. We demo on your own drawings.
