The Austin Airport Expansion and Development Program (AEDP), also known as the “Journey With AUS” program, is a multi‑year capital improvement initiative designed to expand the long‑term capacity of Austin‑Bergstrom International Airport and accommodate rapidly increasing passenger demand. The program includes development of a new midfield concourse with additional aircraft gates, expansion and modernization of the Barbara Jordan Terminal, and significant upgrades to taxiways, aircraft apron areas, and landside access infrastructure across the airport campus.

Major program elements include construction of a new arrivals and departures hall, development of a new 20+ gate concourse connected by underground tunnel, expansion of security screening and baggage handling facilities, roadway realignments, and development of new parking structures and utility infrastructure. When completed, the program is expected to significantly increase annual passenger throughput and support regional growth.

Because Austin‑Bergstrom International Airport remains fully operational throughout construction, the program requires carefully coordinated construction phasing strategies to maintain safe aircraft operations and uninterrupted passenger movement while major infrastructure improvements are implemented.

APR supported WSP and the City of Austin by providing independent conceptual cost estimating and cost advisory services for early planning elements of the Airport Expansion and Development Program. During the initial program planning stages, APR developed structured planning‑level cost models to support evaluation of potential terminal expansion, airfield infrastructure improvements, and landside development scenarios.

APR’s estimating approach incorporated aviation industry benchmarking, historical cost data from comparable airport capital programs, and disciplined conceptual estimating methodologies to produce well‑informed order‑of‑magnitude (ROM) cost projections. These cost models enabled project stakeholders to evaluate alternative development strategies and better understand potential cost implications associated with different program scopes.

    • Developed structured ROM cost models which helped refine an initial ~$6.1B planning estimate to approximately ~$4.2B
    • Applied aviation infrastructure benchmarking derived from comparable U.S. airport expansion programs
    • Identified major cost drivers associated with terminal expansion, airfield development, and landside infrastructure improvements
    • Supported early evaluation of expansion scenarios and capital investment strategies

Provided reliable cost intelligence during early program planning and development phases
