In October 2015, architects met with the Centennial Authority to discuss a potential arena renovation. Their proposal includes all-new entrances, a new rooftop restaurant and bar, covered tailgating sections, and moving the administrative offices elsewhere in the arena as a result. The plans also call for new office spaces, additional meeting spaces, removing stairwells and aisles, adding wider seats, and perhaps building lounges on the mezzanine levels below the main concourse level. Project costs have not yet been decided, as the architects were given until May/June 2016 to come up with estimates. The estimated cost could be almost $200 million. The Centennial Authority would have to approve the estimates before official voting could begin. If the funds are approved the renovation start time would be 2020 and at the earliest, it could be completed by 2022.
