Glavbolgarstroy Advances Bulgaria’s Vertical Gas Corridor

The construction of LOT 1 from the Vertical Gas Corridor, where Glavbolgarstroy has been engaged as main contractor, is completed, while LOT 3 is being built in parallel. The joint ventures “HILL INTERNATIONAL – GBS 1” and “HILL INTERNATIONAL – GBS 3” in which Glavbolgarstroy is a leading partner, are responsible for the implementation of LOT 1 (“Looping from Kulata to Kresna”) and LOT 3 (“Looping from Rupcha to Vetrino”) of the Vertical Gas Corridor.

The construction work on LOT 1 has been completed, and the facility is now in operation. Gas pipeline with a diameter of DN 700 and length of approximately 48 km has been constructed along with the associated facilities. Within a very short timeframe a total of 5 river crossings were completed using the Horizontal Directional Drilling method. The construction work on LOT 3 began just a few months after that on LOT 1 and is still ongoing. The pipeline is approximately 61 km long and has a diameter of DN 1200. The project also includes the construction of 5 technological sites and 3 HDD river crossings. The two projects are situated in different parts of the country, and their implementation requires careful planning and coordination of processes.
