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 messages 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.

For defect evidence, the WECAVIS QM module automatically classifies each reported defect into one of four severity categories - minor, moderate, severe, or critical - based on the submitted photo and description. A Gefahrenmeldung (hazard notice) or Behinderungsanzeige (obstruction notice under Section 6 VOB/B) is stored instantly as a queryable PDF in the central WECAVIS web portal, automatically assigned to the correct project, creating a defensible, organized evidence trail for disputes or claims. Plans start at 99 EUR per month.
