[Edaily Reporter Kim Hyung-il ] Construction AI deep tech startup #SLCORPORATION announced on the 12th that it had won the Korean BIM Society President’s Award for its markerless Building Information Modeling (BIM)-based augmented reality (AR) railway construction inspection technology.

SLCORPORATION earned the honor through an outstanding technical presentation at the “2026 Railway Construction BIM Competition and Smart·BIM·AI Technology Forum,” held on the 11th at the headquarters of the Korea National Railway Corporation. Co-hosted by the Korea National Railway Corporation and the Korean BIM Society, the event was organized to discover and share technologies that will drive the advancement of smart construction technologies in the railway sector, as well as the industry’s digital transformation (DX) and artificial intelligence transformation (AX).

SLCORPORATION presented “AR Railway Construction Inspection Technology Based on Markerless BIM Alignment.” This technology is characterized by its ability to precisely align 3D BIM data with actual railway construction sites—without the need to install separate physical markers on-site—to verify construction quality using AR.

In particular, its potential for use at railway construction sites—where worker access is difficult or the risk of safety accidents is high—garnered significant attention due to its compatibility with drones and robots. It was reported that the judging panel highly evaluated the technology’s ability to rapidly verify construction status, manage construction deviations, and enhance quality and safety.

Lee Yu-mi, co-CEO of SLCORPORATION, stated, “It is meaningful to have SLCORPORATION’s AR-BIM convergence technology recognized at a technology forum hosted by the Korea National Railway Corporation and the Korean BIM Society.” She added, “We will continue to advance spatial intelligence-based digital and AI technologies that can enhance safety and productivity across various industrial sites, including railways, construction, and plants.”
