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. 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 motorw

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.

    Two Manitowoc MLC650s are working on a project to replace the Champlain Bridge that spans the Saint Lawrence River in Montreal, Canada. The engineering consortium - Signature on the Saint Lawrence Construction (SSLC) – is assigned to the task. The capacity and reduced ground preparation made possible by the MLC650’s VPC-MAX attachment – as well as the ease of use of its Crane Control System (CCS) – are helping the team stay on schedule. The Champlain Bridge connects one of North America’s busiest road
