Facility Construction/ Building Technology

Steger AG is a company in eastern Switzerland steeped in tradition with a history that began in 1927. In 1978, this sole proprietorship firm became a joint stock company, which then was integrated into the ID Group in 2004. The opening of our newly built and renovated company offices in Aadorf took place in June 2007, giving Steger AG a new, and modern setting. We are competent partners for our customer’s small and large facilities. Over 100 well-trained employees plan and execute building technology facilities and guarantee a high standard of quality. Together with our customers, we look for optimal solutions, are committed to special customer needs and challenges, and implement them. So as to guarantee our quality standards in the future as well, we continuously train our employees and we are committed to apprentice training. Since training began in August 2010, our new vocational training workshop has been operating with 9 fully equipped workplaces and 5 welding boxes. Our apprentice supervisor took up his post here at the same time. He is responsible for 20-25 apprentices in 7 different occupations and for the prefabrication workshop as well.

Starting on 1 January 2012, Steger AG has focused more on renewable energy sources. A new company department is led by long-serving Project Manager Silvan Romer. This department will continue as before to conduct all service and maintenance work for sanitation, heating and air conditioning systems.
