AIRFIELD 2028 ALL PROJECTS (AIP / AUI / CIRCUITS / FOD) CombinedThe contract encompasses a comprehensive suite of airfield infrastructure improvements scheduled for implementation by 2028, aimed at enhancing safety, operational efficiency, and compliance with aviation standards. Work includes replacing aging airfield lighting circuits that exhibit low megger readings with modern LED fixtures and signage, improving visibility and reducing maintenance demands. Concurrently, failing pavement sections and critical utility systems will be excavated and rebuilt to restore structural integrity and prevent service disruptions. Wildlife hazard mitigation is a major component, involving the removal of turf edge dams along runways, taxiways, and access roads, installation of anti-perching devices on signage to deter birds, and the regrading of low-lying areas alongside new storm drainage infrastructure to eliminate ponding that attracts wildlife. Additional scope includes the replacement of deteriorated flush fire hydrant access hatches to ensure rapid emergency access. All work is being coordinated under the Aviation Project Management Group of the Port of Seattle, with primary contact Yanet Maldonado overseeing procurement and project coordination. The contract is classified under NAICS code 237990 for other heavy and civil engineering construction and reflects a long-term commitment to airfield modernization and safety enhancement.
