Elliot Bay seawall project

HB to Participate in Elliott Bay Seawall Repair and Replacement Project in Seattle


Geotechnical construction contractor Hayward Baker Inc. has been awarded a $41 million contract in connection with the City of Seattle’s Elliott Bay seawall repair and replacement project.

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.

The initial test program is slated to begin in March 2014, following which the seawall repair and replacement project will be carried out over a period of approximately two years. The project team will work closely with the General Contractor and other trade contractors to minimize disruption and inconvenience during peak tourism periods.

The Seattle downtown waterfront area is a popular destination for tourists and locals alike. Among its attractions is the famed Pike Place Market, a public market overlooking the Elliott Bay waterfront. The market opened in 1907, making it one of the oldest continuously operating public farmers’ markets in North America. Pike Place Market also features diverse craft and specialty shops and places to dine, contributing to its popularity as one of Seattle’s most important gathering places.

The first Starbucks Coffee store opened in the vicinity in 1971. In addition, the Pike Place Market Historical District lies along the Elliott Bay waterfront.

Commenting on the Elliott Bay seawall project, Justin Atkinson, Chief Executive of Keller, Hayward Baker’s parent company, stated, “Hayward Baker has a long track record of completing large specialty grouting projects in challenging environments such as high-density urban centers.  In the case of the Elliott Bay waterfront, the need for constructing jet-grouted soilcrete columns around existing timber piles adds more complexity to the project, for which our company is highly suited.”
