Bilfinger Berger continues to expand its services business with the acquisition of the Swiss Rohrbau Group. The industrial services company generates an annual output volume of €55 million, with two-thirds of that total in Switzerland and the remaining third in Germany. The company had previously been management-owned and no details on the purchase price are being disclosed. The acquisition allows Bilfinger Berger Industrial Services to expand its client base and gives it access to the strategically important Swiss market. The Rohrbau Group specializes in the manufacture and assembly of piping systems and devices. The company enjoys a strong market position, especially in the area around Basel which serves as a hub for the European pharmaceutical industry. More than two thirds of turnover is accounted for by this sector. Longstanding client relationships are in place with industry leaders such as Novartis and Merck Serono. The Rohrbau Group is also active in the chemical and fine chemicals industries. Recent acquisitions in Austria and France have considerably strengthened Bilfinger Berger's position in the European industrial services business.
