With pride, Unidome presents a project that achieves the world's largest span with a sustainable biaxial voided slab. As part of the new Loxone Campus in Kollerschlag, Austria, a lecture hall is being built with a roof of 33m x 21m. The 90 cm thick, slightly arched slab is an architectural and engineering masterpiece, made possible not least by the use of Unidome XS-D3 voided elements. Through the use of Unidome concrete formers, 72 cubic meters of concrete and 180 tons of dead load are saved in this slab. In this slab alone, the displacement of concrete prevents 15 tons of CO2 emissions. In the entire project, it should be noted in passing, Unidome prevents more than 125 tons of CO2 emissions. This extraordinary application highlights the versatile use of Unidome for sustainable concrete structures of all kinds.
