Press Release 22 May 2007 STRABAG subsidiary mandated to build Opernturm high-rise in Frankfurt Ed. Züblin AG receives contract worth EUR 230 million – construction of mega-project set to start in the summer of 2007 STRABAG subsidiary Ed. Züblin AG, Stuttgart, has been awarded the contract to build the 170-metre- tall Opernturm project in Frankfurt’s Westend. Opernplatz Property Holdings GmbH & Co. KG contracted Züblin at the end of April for the turnkey construction of the 44-storey skyscraper opposite Frankfurt’s historic Old Opera. The site was acquired by US real estate developer Tishman Speyer, which also built Frankfurt’s Messeturm skyscraper, in 2004. The project, designed by architect Christoph Mäckler, will comprise the Opernturm office tower as well as a seven-storey perimeter block development with a total of 60,000 m² of rentable area. Shops and restaurants will be housed in the two-storey arcade at the tower’s base. An underground parking garage with 580 parking spaces is also planned in the building’s two or three basement floors. Spaces will also be available for visitors of the Old Opera. Züblin Spezialtiefbau GmbH, as part of a working consortium (“Arbeitsgemeinschaft”), is currently at work to excavate the foundation pit and lay the foundation. The actual high-rise construction is to begin on 1 July 2007. Upon completion in the autumn of 2009, the Opernturm, being built at an investment of EUR 230 million, will add a further architectural highlight to the Frankfurt skyline. The first tenant has already been secured – Swiss bank UBS has leased 60 % of the rental space for its German branch office. STRABAG SE is one of Europe’s leading construction groups.
