Weekend Activities and Work

  • On Friday, Aug. 14, Virginia Mason has scheduled maintenance work on the power generators. As a precaution, we will have a temporary generator set up along the south curb lane of Seneca Street, just east of Terry Avenue, through Saturday evening. Apart from initially testing, we don't anticipate using this generator, but we need to have it available as a back-up energy source.
  • We have secured a special work permit from the City of Seattle for Saturday, Aug. 15, to allow us to deliver and install mechanical equipment into the lowest level of the new building. The west, southbound lane of Boren Avenue will be closed Saturday from 8 a.m. to 6 p.m. to facilitate semi-truck deliveries. Appropriate traffic-control personnel will be on duty to ensure safety around the site by helping route pedestrians and traffic.
  • No construction work is planned for Sunday, Aug. 16.

Temporary Closure of Seneca Turnaround Drop-Off Area

  • To ensure the safety of patients, staff and visitors during construction of the connector between the addition and the main hospital, we have temporarily closed the turnaround drop-off area in front of the lobby on Seneca. We anticipate reopening the turnaround in late September.
  • Meanwhile, we have installed appropriate signage to the entrance and exit points from Seneca, indicating alternate drop-off and pick-up locations in front of the Emergency Department, Lindeman Pavilion and Buck Pavilion.
  • Revisions have been made and appropriate signage has been installed to the entrance and exit points from Seneca. Pedestrian traffic from Lindeman Pavilion to the hospital is being re-routed to the east side of Terry Avenue, and pedestrians need to use the east crosswalk across Seneca. 
  • To ensure the safety of pedestrians using the front entrance of the hospital, we have installed a covered, secure walkway in front of the breezeway (near Tully's Coffee) that will allow people to come and go from the hospital on foot. Through that covered area, bicyclists will also be able to access the bike rack near the lobby doors.
  • These measures will remain in effect through the end of September. 

Monday through Friday

  • Construction on the connection from the main hospital to the new hospital building continues.
  • On Monday, we will begin installing steel trusses to the top of the elevator core, which will ultimately support the connecting structure from the addition to the main hospital.
  • As we have noted, the concrete walls you see are not the final exterior walls. This week, we will begin preparations for the installation of the building's façade, beginning on Spring Street.
  • We continue to dismantle the wall forms used to pour concrete for the elevator cores and remove them from the site.
  • Intermittent concrete pours 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 these intermittent pours. Parking on the south side of Seneca also will be unavailable temporarily.
  • Steel deliveries for the main concrete structure continue this week on Seneca and Spring. 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).
  • Residents may hear an air horn on occasion. This is a safety alert to inform workers that a heavy load is about to be lifted across the construction site.

Sidewalk and Street Closures

  • Spring Street - Spring and its north sidewalk between Boren and Terry will be closed 24 hours a day. The south sidewalk will be open to pedestrians throughout the week.
  • Boren Avenue - The westward southbound lane on Boren between Seneca and Spring will be closed during normal construction hours and open after construction hours. The sidewalk will be closed 24 hours a day.
  • Seneca Street - For the time being, the south sidewalk on Seneca between Boren and Terry will be closed. The north sidewalk will be open.
  • Parking Spaces - The four parking stalls west of Boren on only the south side of Seneca will continue to be closed to parking.
