It takes a lot of hard work and dedication to make it to the Olympic Swim Trials, but before the swimmers even arrive, there's lots of work going on behind the scenes. Construction began Monday on the first of two pools to be installed inside the Qwest Center.

While most of us were sleeping early in the morning, crews were busy constructing a warm-up pool for the Olympic Swim Trials that begin next month. It's a big project to say the least. “We're doing things that we've never done before," says Trevor Tiffany of Myrtha Pools.

A few things this project requires are two-million gallons of water, hundreds of thousands of bolts and screws and miles of pipes, not to mention the tons of concert used for the base, miles of vinyl liner, three huge gas heaters and four massive pool filters all used to make a 10-lane, 50-meter pool and an eight-lane 50-meter pool, both temporary.

“After this event, the local fire brigade is helping us get rid of the water so we'll recycle the water, we'll take the pools apart and load them again on the trailer,” says Tiffany. “They're going to Virginia to a swimming club."

Organizers say this event is a chance to see history. "If you look at it from Michael Phelps and his crew of wonderful swimmers, his colleagues, these people are going to win Olympic gold medals and people in Omaha are going have the chance to sit in the Qwest Center just meters away,” says U.S. Swim Trials CEO Harold Cliff.

It's an event that’s expected to be a huge money maker for the metro. "There's about 1,300 swimmers coming,” says Cliff. “We expect attendance between 155 to 165,000 range. Economic impact, it's estimated a little bit north of $40 million."

So far it's all coming together as planned. "We know that they have the best swimmers in the world and we hope we build the best pools in the world, so it's a perfect fit," says Tiffany.

So far, 125,000 tickets have been sold. There are 40,000 still available in all price ranges, including single-day tickets.
