WA Patriot installed retractable hook support systems to replace the existing above ground arrest gear cables in use at a fully operational air field. The arrest gear cables are used for emergency landing arrest. The work included demolition of 15’ x 200’ of steel plates & concrete at the site of the existing arresting gear cable for install of the new arresting gear system. The runways were shut down to air traffic during construction but adjacent runways were operational.

This design-build project consisted of repairing four railroad bridges in the Bremerton and Shelton areas. Two bridges are in Shelton, WA and are mainly steel super structures. The steel bridges’ scope of work involved abrasive blasting to eliminate the existing lead paint coat and applying a new three paint coat system to all steel. Two bridges involved repairing the timber portion of the bridge support. This included posting piles, replacing pile caps, stringers; sway braces, and railroad ties. Headwall and wing wall timbers were also replaced to repair the bridge approaches. Three bridges (0.15, 6.6, and 36.35) also included ballast replacement and rail alignments
