Giant plant completes foundations task at new Champlain Bridge

A massive floating foundation installer (FFI) has completed its work on the new Champlain Bridge and will now be dismantled.

The blue mechanical equipment, better known as Poseidon, has spent months working of the Île-des-Sœurs area’s west approach operations.The FFI, which was designed by Belgian firm Sarens, has now positioned its final foundation on the riverbed.

In all, it will take more than 75 trucks to transport the dismantled Poseidon to a port outside Montreal. Once across the Atlantic Ocean, certain pieces will be reusable on other major infrastructure projects around the world.

Sarens heavy lifting and transport specialist Hugo Saua explained how the lifting apparatus will be dismantled: “We have taken down pieces of its upper portion, such as the rotation system. Next, the vertical towers and their connecting girders will come down. Then comes the lower portion, including the floaters, the floor and their various components. Within weeks, all of the parts will be put away, and there will be nothing left of the FFI.”

The bridge is being built by Signature sur le Saint-Laurent (SSL), which is made up of SNC-Lavalin, ACS and Hochtief.

Alexandre Clouthier, area manager for the west approach, said that Poseidon lived up to expectations. “Design of the FFI began in August 2015, when the west jetty was not fully built and current conditions were different,” he said. "Less than a year later, in July 2016, Poseidon was navigating on the water, putting the very first foundation in place with surgical accuracy. The operation was a tremendous success, thanks to constant cooperation between SSL and Sarens.”
