We are writing to provide the latest information about our hospital addition construction project.

Weekend Activity: Saturday, June 21, and Sunday, June 22
No work is planned this weekend.

Activities for the Week of June 23
Drilling and installing steel piles along the west side of the worksite is now complete.

Excavation continues, and soil is being hauled from the site, increasing truck traffic during normal construction hours (weekdays between 7:30 a.m. and 6 p.m.). We expect excavation work to last into August.

This week, we will continue duct-bank work in front of the John Winthrop Apartments on Seneca Street. (A duct bank is a group of underground conduits, usually embedded in concrete, that serve in place of overhead utility lines.)

We have opened a trench to the east and west of the new vault in the parking lane. The vault will house and connect underground utility cables, and is a preferred alternative to running cables above ground and across utility poles. This week, we will continue work with Seattle City Light to install the duct bank. This work will take place over the next several weeks as it requires us to work around existing utility lines and to coordinate schedules and efforts with City Light.

The second trench, which was opened on Boren Avenue, just south of Seneca, will be restored as of Friday, June 20. This work was for a storm-drain connection (to accommodate rainwater run-off and drainage from roofs) underneath Boren that will connect to the new building.

Sidewalk and Street Closures for the Week of June 23
Spring Street
- Spring and its north sidewalk between Boren and Terry avenues will be closed 24 hours a day.

The south sidewalk will be open to pedestrians throughout the week. If additional work is required in the alley, a wooden pedestrian footbridge will be installed over the alleyway to allow for access and passage.

Boren Avenue - The westward southbound lane on Boren between Spring and Seneca will be closed during normal construction hours and will be 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 this week. At times, we will have flaggers on the north sidewalk helping direct pedestrians as we have done previously.

The four parking stalls west of Boren on both sides of Seneca will continue to be closed to parking.

Additional parking spaces along the north, westbound lane of Seneca may need to be closed, including a Zone 21 Permit Parking Load/Unload area, to ensure the safety of the public and workers on the site.

Once again, we thank you for your patience throughout this period and apologize for any inconvenience these activities may cause. As updated information becomes available, we will be sure to share it with you.
