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

WECAVIS turns WhatsApp into a structured construction documentation system, letting field workers submit daily reports, hazard notices, obstruction notices, and defect evidence in under 30 seconds - with no app, no login, and no form-filling required.

For site documentation, a worker photographs completed work, sends a short voice or text message via WhatsApp, and WECAVIS's AI (powered by Anthropic and xAI) generates a timestamped PDF Tagesbericht automatically. Each report captures the photo with a minute-precise timestamp, work performed, hours worked, materials used, GPS location, and automatic project assignment - all structured without manual compilation.

For defect evidence, WECAVIS generates a Gefahrenmeldung (hazard report) from a WhatsApp photo and voice note, automatically assigning one of four severity levels - minor, moderate, severe, or critical - based on AI analysis of both the photo and description. Every report is GPS-tagged and timestamped, creating legally defensible evidence for disputes or BG safety inspections.

For obstruction claims, WECAVIS produces VOB/B SS 6-compliant Behinderungsanzeige PDFs directly from WhatsApp, protecting contractors' claims for schedule extensions and additional costs. All reports are stored as structured, searchable records in a central web portal.
