Need Overview

Need Name: ANC PBB - Replace Passenger Boarding Bridges - B4/N3
Type:
Funding Source:
Category:
Sub Category:
Estimated Cost: $5,875,000
Description: Install new passenger boarding bridges (PBB) with a 400hz ground power frequency converter at Gate B4 on B Concourse and Gate N3 at the North Terminal. Existing PBBs will be evaluated through the Design-Build process to determine if the PBB should either be sealed and stored for future reinstallation in a less demanding location under a separate project, or disposed. Given the ages of both PBBs, they will likely be disposed.
Priority: ASAP
Need Origination: Other
Justification: The B4 PBB will be 39 years old when replaced. The N3 PBB was installed as part of the North Terminal construction in 1985. Locating and purchase spare parts has become increasingly difficult. The manufacture of N3 PBB no longer manufactures or stocks parts for the PBB. The new PBB at B4 and N3 will be more dependable and functional and have less down time. New passenger boarding bridges have increased safety features, enhancing safety for passengers, ground support personnel, and passenger boarding bridge operators. They also provide features better protecting planes from damage at the gate. New passenger boarding bridges operate with increased dependability, lowering maintenance costs and have lower operating costs due to more efficient components. They are less likely to become inoperable at operational maximums or minimums requiring resetting by Facilities Maintenance personnel. 400 Hz aircraft service lowers aircraft and mobile Ground Service Equipment (GSE) emissions. Existing terminal electrical service may require upgrading to provide 400 Hz at each PBB. A professional evaluation of terminal electrical systems and service capacity and systems is proposed early in the PBB replacement program, to more fully explore costs and benefits. PBB 400 Hz can also charge electrical GSE when aircraft are not being serviced at the gate.
