New Viaducts Transforming Mobility in Brazil

One of the main challenges was to build the viaducts with spans of up to 75 metres without interrupting traffic on the Via Dutra, regarded as the busiest road in Brazil. This scenario required formwork, shoring and scaffolding solutions that combined safety, technical precision and speed of execution.

The Balanced Cantilever Formwork Carriage CVS was a key solution, as it enabled the casting of 5.25-metre-long segments entirely in cantilever, without the need for ground supports. This method ensured traffic continuity while optimising execution times for large-span structures. In sections where in-situ concreting over the road was feasible, Heavy Duty Truss System MK was employed. These structures made it possible to cover spans of up to 30 metres, supported by MK shoring towers in accessible areas.

In addition, COMAIN, CLR and ENKOFORM VMK vertical formwork systems were used for the piers, flanges and deck of the viaducts, standing out for their versatility and the high-quality finishes achieved. In sections constructed with conventional formwork, the T-60 and MK shoring systems ensured efficient and safe assembly. For working at height, the BRIO multidirectional scaffolding provided safe and comfortable access routes for workers throughout all phases of the construction process.

Thanks to these solutions, ULMA contributed to a highly complex project with systems that stand out for their safety, adaptability to large spans and ability to optimise execution times, without compromising the final structural quality.

The construction of the new viaducts on the Via Dutra represents a strategic step forward in Brazil’s transport infrastructure, where ULMA’s innovation and expertise have proved decisive to the success of the project.
