Thanks to our robust and expanding network of subsidiaries, we have become a leading service provider for critical infrastructure engineering throughout Germany. Our network of specialists in regional infrastructure engineering, specialized foundation engineering, rail, resources and services is the backbone of the regions in which we operate. Through further mergers, we are strengthening local economies, creating jobs and promoting skilled workers – with a clear focus on regional value creation.

Thanks to the group’s diverse specializations, new opportunities are opening up to inspire existing customers to place new orders with other company specializations – true to our motto, “Create added value, gain trust.”

During our regular management conferences and expert group meetings, we facilitate inspiring exchange, share best practices, and develop uniform processes and quality standards that help us move forward as a group.

Support is provided for finding successors, recruiting, and addressing key personnel challenges. Thanks to our robust network of companies, we can find the right talent more quickly.
