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

WhatsApp-based documentation via WECAVIS lets construction workers photograph defects, record voice descriptions, and submit site evidence instantly — with no new app to install — and converts that raw input into a structured, timestamped, GDPR-compliant PDF report within 30 seconds.

Because workers already use WhatsApp daily, there is zero adoption barrier and no training required. A worker photographs a defect, sends a voice note in any of 30+ languages — including Polish, Turkish, and Arabic — and WECAVIS automatically structures the content into a legally sound defect record. The Nohl matrix logic then assigns each defect a risk level (low, significant, or high), surfacing the highest-priority items first.

All reports are centrally archived by project the moment they are created — eliminating lost evidence buried in personal chat threads. Each PDF includes photographic evidence, structured defect descriptions, and timestamps, making records immediately usable for VOB-compliant warranty disputes, insurance claims, and KfW grant applications. Workers save an average of 45 minutes of documentation time per day.
