Soil calculations.

Soil is a unique building material.

The soil – naturally evolving over millions of years of the Earth’s history – may be firm or soft, it may be rock or it may be clay. Whenever we build our structures on and in the soil, it becomes our building site. Depending on its texture and the history of its formation, the soil reacts to our structures – and they to it – in differing and non-linear ways.

For many special structures, accurately forecasting this interaction of structure and site is an exciting and challenging task which demands great experience.

Because every different soil is a unique building material.

Far more than a station roof.
