Keller Group plc (“Keller”), the international ground engineering specialist, announces that it has been awarded a contract worth $41m (£25m) in connection with the City of Seattle’s Elliott Bay seawall project.
The project involves the repair and replacement of a large section of seawall along Seattle’s downtown waterfront, a popular tourist area. Constructed between 1911 and 1936, the seawall has deteriorated over time, making it vulnerable to storm and earthquake damage.
Using our advanced jet grouting technology, we will construct a grid of approximately 5,500 large diameter soilcretecolumns at depths of up to 26 metres, to provide seismic stability and foundation support for the new seawall. To work around existing timber piles, we will employ a process of dynamic planning to survey pre-drilled holes, identify obstructions and revise the grid pattern as the work proceeds.
A test programme is expected to begin this March, following which the work will be carried out over three years, avoiding the main periods for tourism.
Justin Atkinson, Keller Chief Executive, commented:
“Keller has a long track record of successfully completing very large specialty grouting projects in difficult environments around the world. At Elliott Bay, the particular challenges associated with constructing jet grouted columns around existing timber piles add complexity to this contract, which plays to our strengths.
“Increasing our participation in large and complex projects remains one of our key aims and we are delighted to have been selected to work on the Elliott Bay seawall project.”
