Professional Airport Planning Services, Airport Master Plan – Chattanooga Metropolitan Airport (CHA) has recently been growing by double-digit percentages over the past few years, resulting in the need to expand terminal processors. As part of the master plan, InterVISTAS developed a 20-year forecast as well as detailed aircraft flight schedules to provide a planning-level synopsis of future aviation activity and generate the terminal facility requirements.
Based on our understanding of the unique operational characteristics of CHA and its passengers, as well as our experience at other airports, we prepared a future program tailored to their situation. This program was then confirmed using industry standards and guidelines from the International Air Transport Association (IATA) Airport Development Reference Manual, 10th Edition, and Airport and Cooperative Research Program (ACRP), Report 25, Airport Passenger Terminal Planning and Design.
Despite the passenger increases forecasted over the next twenty years, the existing check-in lobby and number of check-in desks was determined to accommodate passengers through the planning period. These findings are consistent with industry trends which involve the increased use of mobile and self-service check-in which results in fewer passengers requiring the ticketing lobby, and for those that do, a shorter visit overall.
While the number of security screening checkpoint lanes did not require much growth, expansion of the lanes was required to accommodate additional queuing and circulation space for a more pleasant experience and optimal.throughput levels. Using these requirements and future forecast, InterVISTAS generated seven future concourse expansion alternatives for evaluation to meet the 20-year planning horizon. From there, a program to meet near-term demand was developed. Employing a sustainable framework for evaluation of the alternatives, the Authority and InterVISTAS collaborated on the selection of the preferred alternative. The selection maximized use of the existing facility, while providing the capacity to accommodate the next 10 years of growth.
In the end, one of the major factors was the ability to phase into the ultimate terminal development with minimal disruption to the existing operation, allowing air service to continue to grow during construction.
