ROUTi-AR is a software solution developed for the construction industry that allows users to inspect, design, and manipulate end-to-end layout BIM (Building Information Modeling) data directly on construction sites through an AR overlay and obstacle-avoiding design automation algorithms. ROUTi-AR enables users to export BIM data, intuitively design MEP (mechanical, electrical, plumbing) layouts on-site, then import the newly-created design directly into their original BIM model. It is the only application that can import new AR design data back into the original BIM model while other construction technology solutions require designing component routes one at a time on a design workstation.
