Beginning with the Hwaseong ITS upgrade in 2021, we have widened both our scope of work and our geographic reach every year. Registering a corporate R&D centre and gaining venture certification in 2022 gave us an engineering base; the 59-site expressway EV charging display programme took us into the private sector in 2024; and the Busan BIMS project opened the metropolitan market in 2025.
