Calculator Pro BTP calcule vos métrés et génère des devis structurés pour le bâtiment : béton armé, escaliers, toiture, peinture, menuiserie, plomberie, électricité. Devis quantitatif ou estimatif, TVA personnalisable, 100% hors-ligne
Turn raw takeoffs into structured, auditable bills of quantities with coded items and rate columns.
From structural drawings to traceable concrete/rebar/formwork quantities — no fabricated numbers.
Paste your site-visit notes — messy, voice-memo, or bullet points — and get back a complete, customer-ready job quote with line items, labor, and a total. Works for HVAC, plumbing, electrical, and general contracting.
Audits, normalizes, and levels multi-quote subcontractor bids for general contractors and estimators. Runs programmatic trade-variance calculations, detects hidden scope gaps, and generates dual-version bid leveling reports and supplier RFI drafts.
Calculates job costs and margin for HVAC, plumbing, electrical and similar trades. Produces structured cost breakdowns, margin risk flags, and dual internal + client-facing summaries.
Build construction programmes with proper logic, realistic durations, and a real critical path.
Paste a French listing and get the memo the numbers actually support. Price per m² vs the local market. Gross and net yield on total acquisition cost — with the post-LF2025 frais de notaire for that département, which most tools get wrong. Cash-flow across three scenarios, every formula visible so you can correct it. Tax regimes compared, including the 2025 LMNP clawback. Red flags, negotiation levers with the arithmetic, documents to obtain first. Decision-support analysis, not advice.
From bar marks to bending schedules, verified laps, and waste-minimised cutting plans.
