Project Update | Highline High School
Workers are drilling 25 feet in the earth 2,300 times to install deep aggregate piers for the new Highline High School. The foundation piers are made of compacted gravel.
Demolition wrapped up at the beginning of November 2019. Now Skanska construction crews are doing rough grading to smooth or flatten the site prior to construction, installing underground utilities and placing footing framework, steel and concrete.
Workers have begun structural excavation on the north and east sides of the site.
UPDATE: Steelworkers used a tall crane to erect the first structural steel columns and beams in the southeast corner of the building footprint on November 20. See photos added below.
Plans to place HHS tennis courts at the Sunnydale site have been submitted to the City of Burien for review along with plans for right-of-way improvements.
Work is tracking ahead of schedule. We continue to expect the new school, designed by Bassetti Architects, to open September 2021.
