Crews were busy Wednesday putting the final touches on the BOK Center's $3.6 million, 50,000-pound scoreboard.

The technological marvel was lowered nearly to the arena's floor as workers finished its assembly, giving a true sense of its massive size: 30 feet high and 33 feet wide. Even a truck parked next to it was dwarfed.

"Everyone who has seen it has the same reaction," Construction Director Bob Eggleston said with a laugh.

"They all stare with their mouths open."

Made by South Dakota-based Daktronics, the scoreboard has a total of 10 LED screens to display high-resolution live video, instant replays, statistics, graphics, animations and advertisements.

"Very few venues in the country will have better technology than Tulsa's events center," said Eric Covrig of Daktronics. "It will be equal in capabilities to the latest systems in NBA and NHL facilities."

The decorative top is made up of many neon lights and designed to promote the BOK Center.

Then comes the main layer of the scoreboard, which is an octagon of light-emitting-diode screens.

Four of them are 8-by-14 feet and 10 millimeters in resolution, which is essentially the spacing between the individual lights. The lower the number, the tighter the lights.

Four more screens, spaced between each of the others, are 8-by-8 feet and 16 millimeters in resolution.

Below that layer is a 9-foot-tall LED ring screen and then a 3 1/2-foot-tall ring screen. Each is 16 millimeters in resolution.

"Basically, no matter where you are sitting, this will provide you with access to all kinds of video and information," Covrig said.

Prominently displayed is the Williams Cos. logo — the company stepped forward with $2 million to help pay for the scoreboard and is also sponsoring the sporting event replays.

Williams Cos. spokeswoman Julie Gentz said, "We have a long history of supporting the Tulsa community, and downtown development especially, so our sponsorship of the scoreboard is just another way of demonstrating our commitment to the city's growth and economic development."

Project Director Bart Boatright said that without the company stepping forward, the scoreboard "would have been more typical of what a building of this nature would get."

"This really is a major-league scoreboard in a mid-tier city," he said. "Part of me wants to keep it a secret so people will be surprised when they attend events. It's going to blow them away."

BOK Center General Manager John Bolton said he's excited that the technology will "enhance the fan experience," particularly for loyal Tulsa Oilers and Tulsa Talons attendees who will enjoy its features the most.

The scoreboard, suspended with cables, will be about 25 feet off the floor for hockey and basketball games, 40 feet off the floor for arena football games, and can be tucked away in the ceiling during concerts.

Daktronics won the total $4.6 million bid package that also includes the 920-foot-long ribbon board that circles the inside of the arena and the outside marquee sign that will sit at the corner of Third Street and Denver Avenue.

All three — the scoreboard, the ribbon board and the marquee — can be operated from a master control room by a single person.

The $178 million BOK Center is publicly funded by the Tulsa County Vision 2025 sales-tax program.

The arena is set to open in September.
