Building a better Australia.

Everyone has heard about Barangaroo: the transformation of this 22-hectare brownfield site west of the port of Sydney is one of the world’s most ambitious urban renewal projects currently under way. It includes a park, three apartment and office towers, a hotel and casino and a shopping area. Such a big urban development starts by making sure there is a solid ground to build on.

The first phase of the project for Menard Oceania and Soletanche Bachy International (SBIMBJV) involved the construction of the foundations for the three high-rise buildings and the Crown Casino, anchoring them at a depth of more than 25 metres, as well as the construction of the pre-tensioned concrete perimeter retaining walls.

Traditionally the pre-tensioned cable reinforcement for the concrete would be craned in to position on the ground and go through a lengthy cleaning process before the before being secured in concrete. Colmar developed a diesel-powered reel system system that kept the cables dry and clean before they needed and then fed into the conduits onsite.

This system saved Menard Oceania and Soletanche Bachy X amount of time and helped to deliver the project months ahead of schedule.
