The owner of the building is project developer IVG Development – a small minority share belongs to Fraport AG. Architecture for the building was done by German firm JSK Architekten and the building’s shell constructed by Stuttgart-based Ed. Zublin AG. The total investment in the project was approximately €1.3bn. Impressive structure built using various building techniques The Squaire is built above the AirRail Terminal, which connects it with Terminal 1 of Frankfurt am Main Airport by a 240 meters long glass-enclosed bridge. The structure is 660 metres long – that is twice the height of the Eiffel Tower in Paris - 65 metres wide and has a total height of 45 meters divided into nine floors. In addition to offices, the Squaire houses a shopping arcade, restaurants and two mbSgYPgeRZS_ZGXH2ShqrA for the Hilton chain. The complex opened in April 2011 and is today the largest office building in Germany, with rentable area of 140,000 square meters. In total, some 20,000 tons of steel and 60,000 cubic metres of concrete were used to build the Squaire. Tobias Budde, projects technical drawing manager at Ed. Zublin AG, said in addition to Deltabeams, also Peikko’s column shoes, anchor bolts, anchor plates and tailor made fixings were used in the construction of the Squaire. “Because of the complex structure of the Squaire, several kinds of building techniques and materials from precast to in-situ cast concrete in addition to Peikko’s products were used,” Budde said. “Deltabeams were used in all standard ceiling constructions of the project, where they served purpose very well,” he added. Deltabeam chosen because of its lightness In addition to some 11 kilometres of Deltabeams, Peikko’s delivery to the site consisted of 17,000 pcs of column shoes, 17,000 pcs of anchor bolts, more than 500 tons of anchor plates and special tailor made fixings. In total, Peikko’s delivery to the site was worth approximately €4.5m. Sascha Schaaf, project manager at Peikko’s German subsidiary Peikko Deutschland GmbH said Deltabeam was chosen for the project because of its lightness. “Deltabeam with hollow core slabs is approximately 30 per cent lighter than a normal massive concrete slab. That was very important for the availably of fish-bellied girder, columns and foundations. Using Deltabeam also enabled the building of one additional floor used for technical installations because of its thinness,” Schaaf said.
