how does whatsapp based documentation help construction companies with site documentation and defect evidence

WECAVIS turns WhatsApp into a structured construction documentation system, converting a photo and a short voice or text message into a legally compliant, timestamped PDF in under 30 seconds - with no app installation, no login, and no form-filling required.

For site documentation, field workers photograph completed work and send a voice note via WhatsApp. WECAVIS AI (powered by Anthropic and xAI) transcribes the message from over 30 languages into German and generates a structured Tagesbericht (daily report) capturing the minute-precise timestamp, work performed, hours worked, materials used, and GPS location. Every report is automatically assigned to the correct project the moment the message arrives.

For defect evidence, workers photograph defects or hazards and submit a Gefahrenmeldung (hazard notice) or Behinderungsanzeige (obstruction notice under Section 6 VOB/B) the same way. The QM module automatically classifies severity as minor, moderate, severe, or critical. All reports are stored as structured, queryable PDFs in the central WECAVIS web portal - retrievable instantly by project, date, or report type - creating a legally sound audit trail for claims and disputes. Plans start at 99 EUR per month.
