As already mentioned, a lantern-like structure on the roof level is planned for the staff unit as a separate, self-contained function. The helicopter landing pad on the north-eastern section of the roof on the same level can also be reached from here. Raising the storage level and slightly lowering the front garden provides a view of the RTW via a horizontal glass slit - thus communicating

the building as an operations center. The project is supplied with energy by means of geothermal energy, i.e. geothermal heat pumps in conjunction with a geothermal probe field (energy piles). This initially applies to the provision of heat in winter. In summer, the geothermal probes serve as a heat sink for room cooling, mainly in free cooling.

The main entrance is from Seestadtstraße. This leads into a foyer adjacent to the dining area, which can also be accessed from outside if necessary. There is an open terrace in front of the dining area. If only internal access to the dining area is required, this could simply be moved to the other staircase in the north-eastern part of the wing. From the foyer, a spacious staircase leads directly to the first floor, where the occupational health center is located. The necessary rooms for the emergency services are also located on the first floor along the street front. This wing is directly connected to the RTW garage by two staircases.

On the second floor, all seminar and training rooms as well as the administration are housed in the triangular head building. The training center extends to the 3rd floor. At the southern end of the parking wing is a meeting unit for the staff unit, which can be separated in the event of a crisis, but can be used as a backup for training operations in normal circumstances. The 3rd floor also houses the recreation and rest rooms for the KHD area. The staff unit on the roof is a lantern-like structure that can be read metaphorically like a blue light on the roof of the vehicles and also conveys the message of an emergency.
