how do roofers and carpenters use whatsapp to create legally compliant construction documentation

Question

Accepted Answer

Roofers and carpenters use WECAVIS to turn 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.

The workflow covers four document types that 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, and site conditions in a structured PDF.
Behinderungsanzeige (obstruction notice): Generates a VOB/B Section 6-compliant PDF documenting obstructions that delay work, protecting claims for schedule extensions or added costs.
Gefahrenmeldung (hazard report): Creates a GPS-tagged, timestamped PDF with an automatic severity rating - minor, moderate, severe, or critical - for unexpected finds like moisture or suspected asbestos.
Materialanforderungsbericht: Tracks material requests across four statuses - open, ordered, delivered, received - and assigns every request to the correct project automatically.

Every report is assigned to the correct construction site the moment the WhatsApp message arrives, creating an auditable, queryable record in the central WECAVIS web portal.
