Astralink is a quality-assurance platform for the construction industry that uses augmented-reality technology to bridge the gap between 3D digital blueprints (BIM models) and real-life construction field work. The system is designed to detect mismatches between the BIM model and as-built throughout the construction project lifecycle. Astralink's system is designed to reduce construction costs by using computer-vision technology to prevent construction errors. The technology is fast, mobile, and can be operated by anyone.
