The strategic construction project of the Pardais viaduct counts on the expertise provided by ULMA
The 800-metre-long viaduct consists of a bridge deck supported by 19 piers and a 140 metre-long, 38-metre-high arch. “The most complex part of the construction of this viaduct is undoubtedly the arch. Due to its construction process, we adapted the T-500 tower system, a heavy-duty system with H 33 trusses that allow large spans to be bridged. We positioned these towers in the ideal places to place hydraulic jacks that would allow us to correct the heights of the two half-arches. Finally, we created a central beam where the arch is tensioned and compressed in order to be able to brace it without the problem of introducing unforeseen loads.”, comments Nuno Filipe, Site Manager, Construgomes Engenharia.
ULMA’s close collaboration with the customer and its comercial, logistical and technical suppor throughout the Project has been key, providing optimised formwork and shoring solutions, as well as creating acesses and working platforms that contribute to improving efficiency and safety on site.
