In 2016, the city completed a project to expand, renovate and modernize the facility and to create closer integration with Hemisfair and Alamo Plaza. The project included goals to remove fixed interior structures to allow for more flexible use of space, and a major upgrade of the building's technology. The effort was carved from a $550 million bond approved in 2012, and had an initial budget of $325 million. This was the largest capital project in the city's history. Construction was awarded to a joint venture of San Antonio-based Zachary and Indianapolis-based Hunt Construction Group.
