The history of Abbruch Oberndörfer & Klessa GmbH goes back to the post-war period, when Max Klessa laid the foundation for our current company in the then bombed-out Düsseldorf. With demolition and clearing work, he and his employees make a contribution to rebuilding Düsseldorf, which was shattered at the time.
The story takes its course: In the following years and decades, a large number of buildings and facilities are demolished in and around Düsseldorf by Max Klessa and his crew. Max Klessa succeeds in rising from humble beginnings to become a successful entrepreneur. In the year of the fall of the Berlin Wall, Mr Klessa retires from the company due to his age.
The new managing director of Klessa Recycling GmbH is Gerd Oberndörfer, who has already been working successfully for more than 10 years in his father's demolition company in Mülheim an der Ruhr. Mr. Oberndörfer sets new entrepreneurial impulses, so the old depot in Düsseldorf-Lichtenbroich and the somewhat outdated machinery are completely modernised.
In the 1990s, projects - including major projects such as the demolition of the old sack factory on Bruchstraße in Düsseldorf with 20,000 m³ of enclosed space, the demolition of the St. Christopher School in Mönchengladbach with 25,000 m³ of enclosed space, and the demolition of the old Puky factory in Wülfrath with 50,000 m³ of enclosed space - were completed.
At the beginning of the 2000s, the company Klessa Recycling GmbH is renamed Abbruch Oberndörfer & Klessa GmbH. In addition, the branch office in Oberhausen was opened in order to serve the increased demand of customers from the Ruhr area from now on.
In the years that followed, a whole series of further deconstruction and demolition projects were successfully completed in and around Düsseldorf, along the Rhine and in the entire Wupper region. More and more, the Ruhr area is also opened up as an area of activity. Examples of this are the demolition of the former freight station in Essen-Altenessen as well as the UCI cinema centre in Bochum and the locomotive shed in Gelsenkirchen.
Up to now, the company Abbruch Oberndörfer & Klessa GmbH is an owner-managed family business with headquarters in Düsseldorf-Lichtenbroich and a branch office in Oberhausen.
