Civil engineering are methods that require special knowledge and special machines for their execution and whose risks are only masterred by specialized companies.
The product (for example a nozzle beam body or a bored pile) lie so deep in the foundatin that a direct test of the dimensions and the functional capabilities are not possible.
Due to the steadily advancing development of engineering in construction, the area of special deep-building construction ist not always clearly defined by general civil engineering.
For example, techniques for the construcion of bored piles, slit walls, high-pressure injection methods as well as slope and slope safety procedures are added to the special deep-groove construction.
