The Seattle-Tacoma International Airport is working on a multiphased project to optimize the baggage handling system. The Port of Seattle’s goal is to increase screening while achieving maximum outbound baggage capacity within the current airport footprint. PCL was contracted to complete Phase 1 of the Baggage Optimization project, and work was completed and coordinated around other simultaneous airport projects. Precise phasing was required throughout to maintain active airport operations with minimal impact.
Updating the baggage handling system involved installing four new explosion detection machines, installing and commissioning approximately one mile of new conveyor, and decommissioning and removing approximately a quarter mile of existing conveyor.
The project also included the construction of a new checked bag resolution area (CBRA), which required building a perimeter wall that is fire rated for three hours. Constructing the CBRA required extensive coordination and routing in order to tie into the existing house steel and infrastructure, and a fire-rated door layout with little to no tolerance. With future addition phases to come, expansion of the existing exterior wall was also needed for the CBRA and was constructed with radiused steel.
A newly built baggage handling system control room houses over 30 screening monitors, acoustically rated offices, and a perimeter wall that is fire rated for three hours. Two new break rooms were created for conveyor maintenance staff and TSA staff. This required the reconfiguration of an existing ramp — by lowering it 15 feet. Extensive excavation, micro-piles, and soil nails were necessary. PCL used laser scanning technology weekly to monitor for any existing building movement during the excavation and soil-nail installation.
