Keller has been appointed to undertake a £25M seawall replacement project in Seattle, US.
The scheme involves replacing a seawall at Elliott Bay using jet grouted soilcrete column techniques to protect the new structure from seismic and storm damage.
The existing seawall, which protects a popular tourist area of the city, was built between 1911 and 1936 and is now in poor condition making it vulnerable to storm and earthquakes.
Keller will construct around 5,500 large diameter soilcrete columns to depths of up to 26m to create a foundation for the new seawall that can cope with the region’s seismicity.
“Keller has a long track record of successfully completing very large specialty grouting projects in difficult environments,” said Keller chief executive Justin Atkinson. “At Elliott Bay, the particular challenges associated with constructing jet grouted columns around existing timber piles add complexity to this contract.”
