Construction Site Safety Drill Tuesday, Nov. 4

  • At 1 p.m. on Tuesday, Nov. 4, we are planning to conduct a safety drill at the construction site involving the Seattle Fire Department. We expect three to four fire department vehicles, including a hook-and-ladder truck, a fire engine and an ambulance, to arrive at the site with flashing lights and sirens. The vehicles will park along Boren Avenue. The drill will last about an hour. We want all of our neighbors to be assured that this is only a drill. In the event the Seattle Fire Department is called to duty, we will reschedule the drill and keep you informed. 

Removal of Trees

  • This week, as part of the approved project plans, we will remove two trees located on Virginia Mason property along Seneca Street, just west of the construction site. The area is being cleared to make way for a connection structure between the addition and the existing hospital building.

Site Foundation Work Continues

  • Intermittent concrete pours will continue on Seneca and Boren throughout the week. Concrete trucks will begin pouring at 8 a.m. on Seneca and 9 a.m. on Boren. Seneca and Boren will be limited to one lane in each direction during the construction pours. Parking on the south side of Seneca also will be unavailable temporarily.

  • Steel deliveries for the foundation continue this week on Seneca and Spring streets. This work requires temporary parking restrictions on the north and south sides of Seneca (6 a.m. to 6 p.m. weekdays north side; 24 hours/seven days a week south side).

  • As work around the foundation evolves, our activities over the next few weeks will continue to focus on pouring footings, columns and walls, laying rebar, and installing piping and conduits.

  • From time to time, residents may hear an "air horn" from the site. The reason for the safety alert is to let workers in the construction hole know that a heavy load is about to be lifted across the site.

No Weekend Work Planned for Saturday, Nov. 1, and Sunday, Nov. 2.
