BS Spezialtiefbau GmbH & Co. KG was founded in Bochum in 2005 by Dipl.-Ing. Andreas Sauer and industrial foreman and international welding specialist Berthold Schmitt. The company executes complex special civil engineering services, including special drilling methods with the driving of steel pipes up to 10 m in length in one piece and reaming from diameter 355 mm to 820 mm, pre-drilling with an auger from 150 to 600 mm, driving and vibrating work up to 15 m usable length, Berlin shoring, steel construction with walers, bracing and anchor systems as well as temporary bridges up to SLW 60 with spans up to 27 m. As a railway construction specialist, the company carries out work during closure periods and under live operations. A 20,000 m² construction yard in Bochum offers ready-to-use beams and sheet piles as well as an own machinery fleet with two large and one small pile hammer, two lattice boom cranes and an excavator. The company is listed as a prequalified construction company with DB Deutsche Bahn AG. Customers come from railway construction, infrastructure, power plant construction and water management.
