About the Project
The Port of Seattle is optimizing the outbound baggage handling system at SEA (previously Seattle Tacoma International Airport). The new system replaces the aging conveyor system previously in place and allows the airport to meet current and future growth. The old system consisted of several smaller baggage handling systems that were isolated from each other. The Baggage Optimization Program aims to provide the airport with a single, integrated system that provides greater security processing capacity and expanded sortation.
Phase 2 of the program removed and replaced five miles of conveyor and baggage handling systems throughout the basement, baggage, ramp and ticketing levels of the airport. The project included a ticketing conveyor, an expanded security system and an upgraded sortation system for the D, S, B and N gates. Non-BHS scopes included the relocation of airport vendor storage, a brand-new conveyor maintenance shop, upgraded MEP systems and structural retrofit. The construction occurred within the operational airport, with phases designed to minimize disruptions.
A collaborative approach with the Port of Seattle, the TSA, project stakeholders and trade partners was critical to the successful execution of the heavily phased project without impact on ongoing airport operations.
