In 2006, together with Obayashi Corporation, we were awarded the structural construction works of three metro stations, built using closed construction technology, diaphragm walls and mining methods. Over the five years of execution, our team successfully overcame numerous technical challenges.

Deep excavation, the continuous maintenance of surface‑level infrastructure, and the protection of buildings located in the vicinity of the stations placed constant demands on our engineers. Thanks to their extensive professional experience, they were able to resolve these challenges effectively throughout the construction process.
