Our services in civil engineering.


Project planning & management.

We act for you as a general contractor and take care of your project from implementation planning including permits and authority management, civil engineering and cabling to surveying and documentation.

Fiber optic expansion.

Whether in the countryside or in the city, our civil engineering experts reliably bring high-speed Internet to the end user.

FTTH - Installation.

We jet the optical fibers into the fiber optic cables, splice them, then install the house connection, thus ensuring unrestricted access to the digital world.

Open and closed underground pipeline construction.

Whether conventional civil engineering or using special methods such as earth mapping and flush drilling technology – we always achieve the desired goal.


We build the basic framework for your e-Mobility infrastructure – we dig the excavation pit, lay the empty pipes, place the foundations and pull in the required cables.

Measurement & documentation.

After completion of the work, we measure the site using state-of-the-art technology and document detailed information on the infrastructure actually installed and the cabling details.
