Early Morning Noise

  • Button: Receive the weekly construction bulletin via e-mail.Please accept our apologies for the generator noise heard early today around 4 a.m. The noise did not come from the construction site. It originated from the hospital where we are in the process of routinely testing our generators. Unfortunately, the test, which lasts four hours, must be performed prior to scheduled surgeries. That is why it begins so early.
  • Please be advised that Saturday, Sept. 19, we again will test the generators from approximately 4 a.m. until 8 a.m. We realize the inconvenience of this test at this time of day, but national codes and regulations as adopted by the state require the testing on a regular basis to ensure the safety of our patients, staff and the general public we serve.

Weekend Activity

  • No hospital addition construction work is planned for Saturday, Sept. 19, and Sunday, Sept. 20.
  • The temporary generator along the south curb lane of Seneca Street, just east of Terry Avenue, will be removed by noon Saturday, Sept. 19.

Monday through Friday

  • Construction on the connection from the main hospital to the new hospital building continues.
  • As we continue preparations for installation of the building's façade, which will cover the concrete walls, we will continue applying black liquid rubber water-proofing to the building along Boren Avenue. Please note this covering is not the final façade, rather it is an underlying protective covering for the structure, which will not be visible later.
  • We will continue excavating in front of Virginia Mason Hospital, between the addition and main entrance at Seneca and Terry.
  • 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 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.

Temporary Closure of Patient Drop-off Area on Seneca

  • 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.
  • 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.
  • Pedestrian traffic from Lindeman to the hospital is being re-routed to the east side crosswalk of Terry to cross Seneca.
  • We have installed a covered, secure walkway in front of the breezeway (near Tully's Coffee) for pedestrians and bicyclists, who may access the bike rack near the lobby doors.
  • The sidewalk in front of the drop-off area along Seneca is scheduled to be reopened by the end of September.

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.
