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.

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 SS 6 VOB/B, this formal notice is generated automatically from a WhatsApp message, documenting delays with timestamps and photo evidence to protect schedule-extension and cost claims.
Gefahrenmeldung (hazard report): Defects are auto-classified into four severity levels - minor, moderate, severe, or critical - by AI analyzing the submitted photo and description.
Materialanforderungsbericht (material request): Tracks orders across four statuses - open, ordered, delivered, received - and feeds directly into post-calculation (Nachkalkulation).

All reports are stored as structured, queryable records in the central WECAVIS web portal. Plans start at 99 EUR per month.
