SUBJECT:  Passenger Loading Bridge Renewal & Replacement Phase 3 – Action Request (CIP
#C801180) (Short Form) 
Amount of this request:                       $0 
Total estimated project cost:         $14,000,000 
Request Commission authorization for the Executive Director to advertise, award, and execute
two major works construction contracts for the Passenger Loading Bridge (PLB) Renewal and
Replacement Phase 3 Project at Seattle-Tacoma International Airport. There is no funding
associated with this request. 
This request provides authorization to advertise, award, and execute two major works on call
contracts to support the remaining PLB replacements. The previous major work contracts were
used up more quickly than anticipated. The new contracts will provide the necessary mechanical
and electrical contract needs for the remaining Phase 3 bridges on concourse D. The PLBs at
Seattle-Tacoma International Airport have high utilization compared to airports with similar
annual enplanements. In 2019, the Airport processed approximately 336,000 passengers per
bridge, well above the average of the top 20 airports at approximately 220,000 passengers per
bridge. Any unplanned downtime, due to PLB or fixed walkway failure, impacts airlines and
customer service. 
The January 12, 2021, agenda memorandum for this project is attached.
