Austin-Bergstrom International Airport has moved into a new stage of its multibillion-dollar expansion, breaking ground on a project that will rebuild the hidden utility network needed to keep a larger airport running.
The Utilities Infrastructure Campus-Wide project, announced at a groundbreaking ceremony on October 19, will upgrade drainage, power, water and communications systems across the airport site. Officials describe it as preparatory work for the airport’s broader Journey With AUS program, which is intended to prepare the facility for between 30 million and 35 million passengers annually once completed.
Work largely out of sight
Unlike terminal expansions or new concourses, the project will not produce a visible landmark for travelers. Instead, it focuses on the systems that must function reliably beneath and around an airport handling more flights, passengers and construction activity.
The works also include new stormwater and water-quality lines and ponds in the southwestern part of the airport, along with redundant medium-voltage electrical systems and telecommunications duct banks. Officials say the redundancy is intended to reduce the risk of service disruptions as demand on the airport increases.
Additional components cover storm drainage, electrical distribution, hydronic piping, detention ponds and duct banks for information technology infrastructure.
A foundation for later projects
Airport leaders positioned the utility upgrade as a prerequisite for several high-profile developments already underway, including the New Central Utility Plant, the New Arrivals & Departures Hall, and the Concourse B and Tunnel project.
Austin Mayor Kirk Watson said the investment was about preparing the airport for a future passenger base far larger than today’s.
“The investments we’re making in our airport today will serve not only the tens of millions of travelers already using AUS each year, but a new era of 30 to 35 million annual passengers once expansion has completed,” Watson said.
AUS Chief Executive Ghizlane Badawi said the project would strengthen the airport’s resilience and sustainability, even if most passengers never see the infrastructure being installed.
“While much of this work will take place behind the scenes, it is essential to strengthening our airport’s operational resilience, reliability, and long-term sustainability,” Badawi said.
Three-year construction schedule
Design work on the project began in 2024. Construction started this autumn and is scheduled to run until 2029.
The project is being delivered by Sundt Archer Western as prime contractor, with HDR serving as designer.
Funding is drawn from airport cash reserves, current and future airport revenues, future revenue bonds and federal aviation grants. The federal contribution includes about $10.1 million under the Airport Infrastructure Grants program and $6.1 million through the Airport Improvement Program.

Austin-Bergstrom’s investment in behind-the-scenes infrastructure underscores how airports are preparing for both higher passenger volumes and more differentiated travel experiences. That same focus on premium services is now emerging at Washington Dulles International Airport, which is planning a dedicated VIP terminal to be developed and operated by Ireland’s daa International.
