Construction Begins on Austin Convention Center Redevelopment

UnconventionalATX project launches sustainable build phase, setting new standard for green development in downtown Austin

September 3, 2025

AUSTIN, Texas — The Austin Convention Center Department (ACCD) is celebrating a milestone in the redevelopment and expansion project, known as UnconventionalATX, having officially entered the first phase of construction. While demolition of the existing facility continues, crews have now begun diaphragm wall (D-wall) activities, the critical first step of true structural construction.

“This milestone signifies more than construction—it represents years of community collaboration, thoughtful analysis, and broad public engagement,” ACCD Director Trisha Tatro said. “We are building more than just a venue—we’re building Austin’s future. This facility will reflect the city’s spirit of innovation, its global appeal and its commitment to inclusive growth.”

The D-wall system will form the perimeter earth retention and foundation structure for the new convention center, supporting future excavation and below-grade construction. Over the past week, crews began trenching operations on the east side of the site between 2nd and 3rd Streets. Specialized equipment is cutting deep, narrow trenches that are reinforced with steel cages and filled with concrete to create massive underground wall panels.

Initial concrete pours are already complete, rebar cages are being installed, and foundation removals in adjacent areas are progressing to allow for additional wall segments. Together, these activities represent the true beginning of vertical construction activity for the redevelopment project.

Designed to achieve LEED® Gold certification, the redeveloped Convention Center will be one of the most sustainable public projects in Austin’s history. To date, approximately 75% of demolition materials have been recycled or reused, including the salvaging of structural steel trusses that will be incorporated into the new building.

The new construction emphasizes responsible growth through:

• Energy Efficiency and Clean Power: Solar-ready roof design, advanced building systems and high-performance materials will cut emissions and operating costs. The facility will run on 100% renewable energy with a vision to achieve ILFI Zero Carbon certification and align with the Austin Climate Equity Plan.

• Water Conservation: Onsite stormwater management and rainwater harvesting systems will reduce potable water use and help recharge Austin’s aquifer.

• Sustainable Materials: Preference for low-carbon, recycled and locally sourced materials will reduce environmental impacts.

• Green Public Space: Expanded tree canopy, outdoor plazas and open-air gathering areas will provide shade, comfort and walkability.

• Connectivity: Safe, accessible pedestrian and bike-friendly connections will integrate with Austin’s downtown mobility network.

The projected $1.6 billion investment is fully funded by Hotel Occupancy Tax (HOT) revenues, Convention Center revenues, and the state’s Project Financing Zone — not property taxes. The project is also delivering broad economic and cultural returns estimated at:

• $285 million boost to the annual economic impact, raising the Convention Center’s yearly contribution to nearly $750 million.

• 1,600+ new jobs in the hospitality and tourism industries.

• $13 million in additional annual tax revenue to the City of Austin.

• $17 million dedicated to public art and 10 local artists, including Austin’s first-ever program of architecturally integrated artwork.

“Austin is proving that growth and sustainability can move forward together,” said Tom Noonan, President & CEO of Visit Austin. “The new convention center will not only expand our ability to host world-class events, but it is being built with recycled materials, energy efficiency and community spaces in mind. This approach strengthens Austin’s position as a global destination while creating real benefits for local businesses, workers and residents.”

Construction will continue over the next several years with updates shared regularly with the community.
