WHY IT EXISTS

Why This Tool Exists

The Problem

Construction teams struggle with fragmented BIM data across disciplines and project phases. Teams manually manage clash detection, coordinate models across multiple file formats and locations, and struggle with real-time communication about design issues. Clashes and coordination problems are discovered late in the project, leading to costly rework and delays.

The Solution

Cloud-based platform accessible via web browser that enables real-time 3D model viewing, automated clash detection, issue tracking, and team coordination without expensive hardware. Supports multiple file formats (Revit, IFC, DGN, BCF), integrates with existing design tools, and allows teams to communicate directly in the 3D model context.
