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 - 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 messages from over 30 languages into German and generates a structured Tagesbericht (daily report) capturing a minute-precise timestamp, work performed, hours worked, materials used, and GPS location. Reports are automatically assigned to the correct project and stored in the central WECAVIS web portal immediately.

For defect evidence, workers photograph a defect or hazard on site and send a short description. The AI generates a structured PDF with one of four severity classifications - minor, moderate, severe, or critical - assigned automatically. A Behinderungsanzeige (obstruction notice) under Section 6 VOB/B can be created the same way, producing court-admissible evidence the moment a problem is discovered.

Because workers already know WhatsApp, there is no training overhead and documentation happens in real time rather than retroactively.
