New Organization

2019 Gruner has reorganized itself and introduced a new management and organizational structure. The starting point was the current customer and market needs, the changing offerings and a powerful and agile target organization with clearly segmented Business Units at the center. The Business Units are grouped into the three business areas of Buildings, Infrastructure, and Energy according to their customer segments.
