ALE Uses innovative Mega Jack to install Perth Bridge

ALE executed the complex lifting and installation works for two 400t steel wishbones that form the large central arch of the bridge, with the completed arch reaching 72m above water level at its highest point.
For these manoeuvres, ALE utilised barges on the Swan River to float the wishbones to the designated piers and used the Mega Jack as temporary 50m towers to pull the wishbones up. The first lift was successfully completed on 27th April using strand jacks with the second lift and the concurrent docking operation successfully completed on 12th May.
Once the two 120m-long wishbones were lifted into place, they were held securely using the strand jacks until they were welded, to create the complete central bridge arch.
Frank Janssen, ALE’s Project Manager, explained: “We are delighted to be involved in this landmark project for the city. This was a technically challenging operation involving the majority of our transport systems and technical knowledge such as SPMTs, strand jacks, barges, hydraulic jacks and the Mega Jack System. We provided a time and cost-effective solution using our specialist equipment and expert operators. The successful arch installation marks a significant milestone towards the completion of the bridge.”
The new Matagarup Bridge, located on the Swan River, will connect the eastern side of Perth city with the Burswood Peninsula, where a new 60,000 seat stadium was recently opened. Built for pedestrians and cyclists only, it forms an important part of the transport options for major events and provides a permanent link for residents and visitors to enjoy parklands and other entertainment.
