Construction of a natural gas storage facility
Construction of a Natural Gas Storage Facility
For our client WINGAS, we delivered the construction of a modern natural gas storage facility. The project comprised extensive earthworks and concrete works as well as complete interior construction. Key challenges included the creation of media‑tight surfaces, complex pipeline construction and the integration of cable ducts made from reinforced precast concrete elements.
In addition, we took on the technical building services and execution planning.
