The Construction Management Association of America (CMAA) Pacific Northwest Regional Committee and the National Committee awarded SEA Baggage Optimization Phase 2 project with two awards for 2025.
CMAA Pacific Northwest Regional Committee–Project of the Year
On June 26, our team accepted this top honor at the CMAA Pacific Northwest Awards ceremony hosted at Ivar’s Salmon House in Seattle, Washington. The team also collaborated with the Port of Seattle to give a presentation about the program at the award ceremony.
CMAA National Committee–Project Achievement Awards
CMAA’s National Committee awarded the Project Achievement Award in the Transportation value greater than $50 Million category to the Seattle-Tacoma International Airport (SEA) Baggage Optimization Phase 2 project. The Project Achievement Award recognizes the project that best exemplifies excellence in design, construction and innovation.
I’m incredibly proud of our team’s success on the Baggage Optimization Phase 2 project. Executed in an active bagwell, this highly phased and technically demanding effort showcased their resilience, expertise and teamwork. It’s an honor to lead such a talented group.”
Dave Hutt, 51Թ Operations Manager

Port of Seattle is optimizing the outbound baggage handling system at SEA. The new system replaces the aging conveyor system previously in place, allowing the airport to meet current and future growth needs. The old system consisted of several smaller baggage handling systems, which were isolated from each other. The Baggage Optimization Phase 2 project aims to provide the airport with a single, integrated system, offering greater security processing capacity and expanded sortation.
Phase 2 of the program involved removing and replacing five miles of conveyor and baggage handling systems throughout the airport’s basement, baggage, ramp, and ticketing levels. 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 new conveyor maintenance shop, upgraded MEP systems and a structural retrofit. The construction occurred within the operational airport, with phases designed to minimize disruptions.
The success of the Baggage Optimization Phase 2 project is a direct result of our team’s relentless drive and shared commitment to excellence. Their ability to adapt, collaborate and deliver under pressure on a heavily phased baggage project, has been nothing short of impressive.”
