As the Port of Seattle and The Northwest Seaport Alliance Terminal 5 project continues, we expect impact pile driving of steel piles on the uplands of Terminal 5 as early as today, April 3, and will continue intermittently into mid- or late May.
Pile driving is restricted to the following days and times:
8 a.m. to 5 p.m. weekdays;
9 a.m. to 5 p.m. Saturdays;
9 a.m. to 5 p.m. on Sundays and legal holidays for vibratory pile driving only;
No impact pile driving is allowed on Sundays or federal holidays (there will be no pile driving on Saturdays outside the fish window [Aug. 15 to Feb. 15]).
We also want to communicate some of the health and safety measures undertaken at the terminal due to COVID19. The contractor has notified us that these steps are being taken to maintain workplace safety:
-All workers are receiving health screening by a private contractor each morning before beginning work.
-Workers are driving to the job-site in their personal vehicles and have been asked not to carpool there.
-They also are encouraged to take breaks in their own cars rather than the break room.
-Extra cleaning protocols have been established for break rooms, sani-cans and construction equipment.
-Social distancing is monitored and enforced.
-Signage about best health practices has been placed throughout the terminal.
-If folks have any comments, questions, or concerns, please contact us through any of these channels:
Terminal 5 community phone line: 206-787-6886.

ADDED 5:43 PM: Many commenters wondered if the pile-driving posed any risk to the closed-for-cracks West Seattle Bridge. We asked SDOT. The agency’s reply:
We have been working with the Port of Seattle regarding their Terminal 5 construction work. The vibrations and energy from the marine pile driver diminishes exponentially the further it travels from the construction site, and is negligible by the time it reaches the nearest bridge foundation a third-of-a-mile away. Put another way, if this construction equipment posed a risk for the bridge it would be causing much greater damage to the buildings closer by.
In the ongoing analysis, SDOT adds that “we have partnered with an international team of engineering experts to conduct a comprehensive safety analysis which takes into account many external variables, including vibrations from nearby traffic, construction, and maritime activity.”
