GAMMA AR, founded in 2019, provides an augmented reality–based construction management software designed to support construction site managers and craftsmen in their daily work. The platform intuitively overlays accurate 3D BIM models directly onto the physical construction site using mobile devices, enabling clear visualization of plans in real-world context. By leveraging data from Building Information Models (BIM), GAMMA AR reduces errors, improves communication, and enables efficient progress monitoring, ultimately helping construction projects save time and reduce costs.
