how do roofers and carpenters use whatsapp to create legally compliant construction documentation
Roofers and carpenters use WECAVIS to convert a WhatsApp photo and a short voice or text message into a legally compliant, timestamped PDF report in under 30 seconds - no app installation, no login, and no form-filling required.
Four document types protect trades legally:
- Tagesbericht (daily report): The worker photographs completed work, sends a voice note, and WECAVIS AI (powered by Anthropic and xAI) transcribes it from over 30 languages into German, capturing hours worked, materials used, GPS location, and site conditions in a structured, minute-precise PDF.
- Behinderungsanzeige (obstruction notice): Required under Section 6 VOB/B, this formal notice is generated automatically from a WhatsApp message, protecting claims for schedule extensions or additional costs.
- Gefahrenmeldung (hazard notice): AI automatically assigns one of four severity classes - minor, moderate, severe, or critical - based on the submitted photo and description.
- Materialanforderung (material request): Tracks orders across four statuses - open, ordered, delivered, received - for post-calculation (Nachkalkulation).
All reports are stored automatically in the central WECAVIS web portal and assigned to the correct project instantly. Plans start at 99 EUR per month.
