history
The two companies emerged from Wayss & Freytag AG, which in turn emerged from Freytag & Heidschuch , founded in 1875 , which Conrad Freytag had sold to Gustav Adolf Wayss in 1890. After Freytag took part in the company again in 1893, it was continued as Wayss & Freytag (since 1900 as an AG). The company was instrumental in the development of iron and reinforced concrete construction by acquiring the patents from Joseph Monier . It gave the development of building technology fundamental impulses through its own innovations. Emil Mörsch headed the technical office of Wayss & Freytag from 1901 to 1904 and from 1908 to 1916 and, together with his employees, ensured the company's technical rise to an international construction company. Other leading civil engineers at Wayss & Freytag were: Karl Walter Mautner , Georg Ehlers , Kurt Lenk, Hermann Bay and Gotthard Franz .
In 1946, the company took part in the founding of the Frankfurt rubble recycling company , which was respected in Germany and around the world. It used the rubble from the war ruins to manufacture new building materials in the rubble processing and recycling plant. Numerous patents of the company, e.g. B. Different segment constructions and connections as well as Mixshield and Hydroshield technology are used successfully worldwide. The company has set international standards in stadium construction. In the 1970s the Wayss & Freytag Group belonged to AGIV . In 1995 the mechanical engineering department of Wayss & Freytag and the Berlin subsidiary H. Klammt AG were merged and GBS (equipment and construction site service) was founded. In 1996 the AGIV group sold its W&F parts to HBG Hollandsche Beton Groep nv (Netherlands). In 2002 the HBG Group merged with BAM NBM to form Royal BAM Group nv (Netherlands). GBS became BAM Services GmbH, an independent company that maintains and stores W&F equipment. BAM Services GmbH became a subsidiary of Wayss & Freytag Ingenieurbau AG in 2008 and was integrated into the company at the beginning of 2011. 1999 Wayss & Freytag AG split into the independent companies Wayss & Freytag Ingenieurbau AG, Wayss & Freytag Schlüsselfertigbau AG and Wayss & Freytag AG Projektentwicklung. 2002 Wayss & Freytag turnkey construction merges with the Göttingen construction company RAULF BAU-GmbH. From January 1st, 2007 further merger with Müller-Altvatter GmbH & Co. KG to form BAM Deutschland AG.
