An engineering company is only as good as the innovative spirit of its employees. Our commitment to this principle has made us one of the most successful electrical engineering companies in Switzerland. With nearly 200 electrical engineers and technicians, we contribute to projects worth some 230 million euros each year. We have helped to realise ambitious projects such as the Prime Tower in Zurich, the Westside Leisure Centre in Bern and parts of the Gotthard Base Tunnel.
Thanks to regular advanced training, the HHM team is always at the cutting edge of technology and industry best practice. We are ready to realise a diverse range of projects not just with technical skill and creativity, but also efficiently and ecologically. In our 68-year history, we have learned that innovation depends on sharing knowledge. True to this insight, we contribute actively to leading professional associations as well as university teaching.
In 1994, HHM was the first electrical design company in Switzerland to receive ISO 9001 certification for quality management. Furthermore, in May 2015, we were granted the «Recognised for Excellence» award by the European Foundation for Quality Management.
