PVS-Hauptverwaltung, Mülheim an der Ruhr

The PORR Building Construction Region West has been working on familiar ground since September 2023. A few years ago, the building construction team built an extension for 170 employees of the Privatärtzliche Verrechnungsstelle(PVS) in the immediate vicinity of the PVS headquarters in Mülheim an der Ruhr. The existing building from the 1980s is now being replaced by a sustainable new building. The Münster branch was once again awarded the shell construction contract. All processes are being synchronised with LEAN, as the schedule is tight.

The energy-efficient refurbishment and upgrading of the existing building was rejected after a detailed assessment. Following the demolition, a contemporary, sustainable head office with a gross floor area of 7,973 m² and 2,902 m² of usable space is being built on the same site according to the designs of Essen-based architect Gabor Kovacs. The light-flooded building, consisting of a basement, ground floor and two upper floors, is tailored to the needs of the employees. There is a staff restaurant, a roof terrace and plenty of green spaces for breaks in between.

Prefabricated parts reduce construction time

Before the actual shell construction work could begin, a chiselling excavator had to loosen the rock in the building ground. Once it had completed the excavation for the haunches, lift underpasses and underground pipes, the foundation and basement were completed.

Due to the high groundwater level, the outer walls of the basement were constructed conventionally using watertight in-situ concrete. The construction of the other storeys will combine in-situ concrete work and prefabricated columns. Due to the very tight schedule, filigree walls are being used in the interior, and many of the columns and staircases are being constructed as precast elements.

The strict environmental regulations of the ‘city by the river’ are also a constant companion on the construction site. Following organoleptic testing, the groundwater was discharged into the public sewage system via sedimentation tanks. In addition, the water compatibility of the hydraulic fluids and lubricants used in the construction site vehicles had to be verified.
