Completed in 1906, the historic King Street Station had since been deteriorating over the years due in part to structural deficiencies. Our firm, committed to restoring this public station back to its original grandeur, provided structural design services for its renovation. In addition to strengthening the century-old clock tower, our firm oversaw construction administration on the project and provided innovative design solutions that addressed the complex constructability issues this historic renovation presented. The project was completed in phases due to funding from various federal, state and city entities as well as to ensure continuous operations for Amtrak. The first phase included repairing the station’s four tower clocks and restoration of the roof that utilized new terra cotta tiles that replicated the original materials. 68 wells and ground-source heat pumps that heat and cool the station were installed in the second phase, along with the development of a new 13,500 square foot public plaza that engages the diverse neighborhood and creates a warm, inviting space. A beautifully renovated staircase bridges the gap from the plaza to the main entrance reconnecting Pioneer Square and the International District. For the final phase, our team structurally stabilized the load-bearing, unreinforced masonry building by inserting steel plates throughout. The station won an award from AIA Seattle’s “What Makes It Green?” program based on its significantly reduced energy usage.
