Things are moving right along in the vicinity of Piers 57-59, on the Elliott Bay Seawall (EBSP). Mass excavation accomplished, cast-in-place slab construction in progress.

Time to share a few images and notes on activity from the past few weeks at the Elliott Bay Seawall Project (EBSP).

Soil freezing keeps groundwater out of the mass excavation zone – it’s been a big success!

Takes lots of power…

… and plenty of coolant!

Soil freeze line doing its thing

The Northwest’s lack of winter 2015 snowfall hasn’t quelled the creative spirit of the folks working on this project!

Rebar comes out … and rebar goes back in …

Soil freeze snowmen

Early 20th century rebar removed

Structural integrity for the CIP slab!

Early 21st century rebar installed

Meanwhile, down at the south end of the project…

Changes at Ivar’s, too…

Scott is at the site most every day.

Construction furiously continues along the historic piers at the Elliott Bay Seawall Project (EBSP). Much activity in progress, including jet grouting for the Improved Soil Mass (ISM) and careful excavation to prep for habitat bench and wall panel installation. Photos and videos below.

Look here for a conceptual view of what’s being constructed. See the New and Improved Seawall illustration. Waterfront Seattle’s February 12th update highlights the new seawall face panels being installed.
