Columbia Metropolitan Airport’s Passenger Boarding Bridge Improvement Program


The Columbia Metropolitan Airport (CAE) hired us and project partner firm, BNP Associates, Inc. to develop a multi-year, multi-phase improvement program for nine passenger boarding bridges (PBBs). This $5M program included an analysis of existing boarding bridge capabilities, parking keys, and a variety of ground service equipment improvements.


Our team worked with CAE to investigated a number of alternatives, including the consideration of new versus refurbished PBBs. Following an analysis and discussion with CAE staff, bid packages for refurbished bridges at all gate locations were developed. Improvements included the removal of Gate 8, as well as the installation of a new gate, modifications to hold rooms, and upgraded baggage conveyors at Gates 7 and 9. Additionally, the project also included significant electrical upgrades to serve the refurbished systems, trial tests, and a “train the trainer” program in advance of operations. To minimize passenger disruptions during construction within the active terminal, significant coordination with airport staff was vital, as well as expediting various phases during pre-planned closures such as nights and weekends.


Prior to the end of 2020, all nine PBBs were replaced, providing a wider range of aircraft usage and greater flexibility in airport operations.
