MARINE: GREATER THAN $5 MILLION

Pier 62/63
By Pacific Pile & Marine
Pier 62/63 in Seattle, Wash. is the former site of the annual
“Summer Nights at the Pier” concert series, at which
performances were punctuated by the sound of docking
and departing ferries. Although occasionally hosting other special
events, for most of the rest of the year, the pier provided a place
to stroll out over the water to view Elliott Bay and the Olympic
Mountains to the west, and the Seattle skyline to the east. However,
the pier was aged and deteriorating, and was no longer able to bear
the load of heavy weights.
The City of Seattle is rebuilding Pier 62/63 in partnership with
Friends of Waterfront Seattle as part of the Waterfront Seattle
Program. The rebuilt pier will be a place to stroll, enjoy views,
play and once again host events like the “Summer Nights at the
Pier” concerts.
Pacific Pile & Marine (PPM) was contracted to rebuild the
southern half of the pier (Pier 62) and retain the northern half (Pier
63) in place. This included replacing the aging wood piling with
steel piling and timber deck with a textured concrete deck while
retaining the existing size and shape of the piers.
The work also involved construction of a Habitat Intertidal
Zone (HIZ). The HIZ was the final and most visible element in a
series of Elliott Bay seawall environmental improvements along
the downtown Seattle waterfront.
Pile driving
PPM replaced the aging timber piles by removing them with a
vibratory pile extractor. Once the timber decking and piles were
removed, PPM then installed 175 steel pipe piles with a vibratory
pile driving hammer to support the new pier structure. The piles
ranged from 70 to 140 feet in length, with eight piles for the floating
concrete dock section of the pier needing to be galvanized.
