Hotel Interurban

The nineteen-story Hotel Interurban complex is the centerpiece of Southcenter redevelopment and the tallest building in the area. The tower, in close proximity to the Seattle-Tacoma International Airport, includes 189 hotel rooms in the lower levels and over 300 residential units in the upper levels. Two skyclubs on the roof provide 360° of unobstructed views of the surrounding mountain ranges. 

​​

Our engineers incorporated post-tensioned flat-plate floors and concrete shear walls to realize the architect's goals. This project also includes a long-span post-tensioned parking garage adjacent to the tower to provide economical parking for residents and guests. 

​

To overcome challenging soil conditions, steel piles were provided to support the tower and the garage.
