Austin council nearly triples an airport utility contract to $344 million, without discussion

The Austin City Council on Thursday raised the ceiling on a construction contract at Austin-Bergstrom International Airport by $224 million, to $344 million. The work covers the pipes, power lines and drainage that the airport's planned new buildings will depend on.

The item drew no discussion from the dais. It was item 27 on the consent agenda, which the council adopted without objection, with Council Member Natasha Harper-Madison absent. The contract is part of an airport expansion whose price tag now exceeds $5 billion, KUT reported in January.

What the contract covers

Our record of the item, 26-2655, describes it as an amendment to the construction contract for the Airport Expansion and Development Program's Utility Infrastructure Campus Wide Project, with Sundt/Archer Western. The amendment adds $224 million, for a new total not to exceed $344 million. The record says the money is available in Austin Aviation's capital budget.

Texas Construction Hub reported that the work provides shared systems for:

• a future central utility plant;
• the new Arrivals and Departures Hall;
• Concourse B and the tunnel connecting it to the existing terminal.

That includes storm-drain trunk lines and water-quality ponds, backup medium-voltage power, a reclaimed-water main, and communications and electrical lines. The outlet reported that the city is using a "construction manager at risk" approach. Under that approach, the contract ceiling sets spending authority, and separate guaranteed-maximum-price packages define the actual work.

How it got here

According to Texas Construction Hub:

• November 2023: The council approved the construction-manager-at-risk delivery method.
• July 2024: The council approved the original $120 million agreement.
• Oct. 14, 2026: The Airport Advisory Commission recommended the increase 11-0.
• Oct. 19, 2026: The airport held a groundbreaking for the utility work.
• 2029: Expected completion.

The outlet also reported federal grant pieces of about $10.1 million from Airport Infrastructure Grants and $6.1 million from the Airport Improvement Program. Those are parts of the funding, not the contract total.

KUT reported that the expansion adds 32 gates. Concourse B, which this utility work will serve, is expected to open in the early 2030s, and the program is paid for with airport revenue.

What was said

No council member spoke about item 27. During the morning's consent-agenda public comment, one speaker, representing an environmental group, urged the council to take a closer look. The speaker described the backup material as minimal and asked whether a change of this size should be rebid. The speaker also questioned how well "guaranteed maximum price" contracts actually cap costs. The speaker put the base contract at $100 million. The city's records list the prior authorization as $120 million, which matches Texas Construction Hub's reporting.

Other airport business in our records

In August, the council also approved on consent a rental car concession with Sixt projected to bring in $440,000 a year. Our legislation page lists other recent airport items, such as tarmac buses and window washing.

What's next

Texas Construction Hub reported that construction on the utility work is expected to start this fall. The guaranteed-maximum-price packages under the new ceiling set what actually gets built and spent. The next major pieces of the program, including Concourse B and the Arrivals and Departures Hall, are still to come.
