Upcoming Building Care Construction Activities: March 25 to March 31

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 25 to March 31, 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
  • Form and pour concrete wall
  • Internal activities on L1 of Forest A (Friends of Costco Building): install hangers, pipes, firestops and seismic restraints for multiple systems; replace ceiling grid and tiles; install infection prevention barriers; install new pipe pathways

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 associated with installing new pipe pathways.

Expect heavy truck traffic 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.

Please call 206-987-8000 or email construction@seattlechildrens.org with questions.

Water Flow Test on March 11

On Monday, March 11, crews will perform a water flow test at the hospital. For approximately 30 minutes, a large amount of water will be discharged from test ports on the south side of Forest A (the Friends of Costco Building). Most of the water will drain into catch basins on Seattle Children’s property, but some will likely drain into the stormwater system on 40th Avenue NE as well. If you see water draining from the hospital that day, there is no need to be alarmed — this is a planned and controlled test.
