Sub-day structures are designed for sustainable use with a long service life of at least 80 to 100 years and result in a high investment requirement.
Underground construction is special compared to other areas of construction.
In contrast to bridge and construction, the properties of the most important building material, the building ground, are often not exactly known in underground construction. As you run, these properties can change quickly. The most important element of underground construction is the timely response at all levels of responsibility to changed circumstances.
Underground construction sites protect the environment, especially if the breakout material undergoes meaningful recycling as a concrete additive or as a bulk material for terrain design. The inevitable interventions in the portal zones and installation sites must be compensated with ecological replacement measures.
With our many years of experience, clear engineering analyses and concepts, we are happy to support you in the project planning and execution of your sub-construction project
