Polish debut

PERI has used its cantilever-construction compatable VARIOKIT for the first time in Poland. The engineering build kit was used to build a new 600m long motorway bridge near the southeastern city of Tarnów. Deploying VARIOKIT allowed the jobsite team to achieve 4-5 day cycles for the bridge's concrete sections.

298 PERI has used its cantilever-construction compatable VARIOKIT for the first time in Poland. The engineering build kit was used to build a new 600m long motorway bridge near the southeastern city of Tarnów.

Deploying VARIOKIT allowed the jobsite team to achieve 4-5 day cycles for the bridge's  concrete sections. It was also said to ensure that the very small tolerances needed for the variable bridge cross-sections could be comfortably met.

Twelve pairs of piers support the two carriageways of the new motorway bridge, each of which is 13m wide. Falsework carried the formwork for the hollow box superstructure of the foreland bridges - consisting of girder wall formwork elements and high load-bearing GT 24 lattice girders. Depending on the support height and load different PERI shoring was used, including ST 100 stacking towers as well as shoring towers on the basis of frame-connected MULTIPROP slab props.

Meanwhile, the near 210m long section between the seventh and the 10th piers was achieved in 48 casting segments using the balanced cantilevered method. For this, contractors 4761 Dragados used four cantilever construction units based on VARIOKIT.

    When it was completed in 1965 – just six years after the Auckland Harbour Bridge – the six-lane Newmarket Viaduct with its tall, slender piers was something of an engineering wonder, the first of its kind in the Southern Hemisphere. Forty years on it had become a much-maligned contributor to Auckland’s chronic traffic congestion, too weak seismically to withstand the heaviest loaded trucks let alone a severe earthquake, so narrow in the shoulders that any accident stopped traffic flow and made it difficult

    A massive construction project has been underway deep in the heart of the Schnecktal valley area in Germany. From the surface, though, you would never be able to tell. The majority of the work is underground, as a joint-venture team led by German contractor Wayss and Freytag Ingenieurbau builds the nearly 7km long Finne Tunnel. After a few years of tunnel boring operations, the contractor is at work finishing the interior of the tunnel, slipforming first the tunnel’s floor and then a walkway with its GOMACO
