Upcoming Building Care Construction Activities: March 11 to March 17

Building Care construction is underway. From now until building opening in Spring 2022, there will be ongoing construction activity at the hospital campus. Seattle Children’s will publish a weekly post on this Construction Blog that outlines the work expected to occur the following week. We will also post to this blog whenever a construction activity will be especially impactful to neighbors.

From March 11 to March 17, construction crews are scheduled to perform the following activities:

  • Excavation
  • Install “lagging” to prevent cave-ins during earthwork
  • Install tie backs/anchors for retaining walls
  • Pour and strip concrete retaining wall

Construction noise will be generated throughout the week. The noisiest external work will be installing tie backs/anchors, which will take place all week. The noisiest internal work will be the core drilling and demolition.

Expect heavy truck traffic all week as excavated soil is hauled away from the site. Construction activity is weather-dependent and subject to change based on conditions.

All work will take place within standard construction hours: 8 a.m. to 6 p.m. Monday to Friday, and 9 a.m. to 6 p.m. on Saturday.
