Hayward Baker to Participate in Elliott Bay Seawall Repair and Replacement Project in Seattle Sponsored

Geotechnical construction contractor Hayward Baker Inc. has been awarded a $41 million contract involving the repair and replacement of a large section of the Elliott Bay seawall along Seattle’s downtown riverfront, involving the construction of soilcrete columns to provide seismic stability and foundation support.

The Elliott Bay seawall project involves the repair and replacement of a large section of a seawall stretching along Seattle’s downtown riverfront. Constructed between 1911 and 1936, the seawall has deteriorated over time, making it increasingly vulnerable to storm and earthquake damage.

The terms of the contract call for Hayward Baker to construct a grid of approximately 5,700 soilcrete columns at depths of up to 85 feet in order to provide seismic stability and foundation support for a new seawall. To work around existing timber piles, Hayward Baker will employ a process of dynamic planning to survey predrilled holes, identify obstructions, and to revise the grid pattern as the work proceeds.
