Four construction companies remain in the running to build the proposed arena in downtown Edmonton, CBC News has learned.

Stuart Olson Dominion, Ellis Don, PCL and Ledcor Builders have bid on the project; of these companies, three are joining forces with other construction firms.

Ledcor submitted a bid with Clark Builders, which just sold a majority share to an American company called Turner Construction.

The New York-based Turner has worked on 51 sports facilities, including Madison Square Garden, Yankee Stadium and the redevelopment of Soldier Field, home of the National Football League's Chicago Bears.

"Clark Builders and Ledcor Construction have done the vast majority of work downtown in the last 10, 20 years, and we're now hooked-up with one of the largest arena and stadium builders in North America," said Bob Walker, Ledcor's vice-president of construction.

Ellis Don has teamed up with Hunt Construction which worked on the home arenas of the Florida Panthers and the Pittsburgh Penguins.

"As soon as we heard word that there was a chance of renovating the existing facility or potentially building a new one, we got working on building up our team, so that we were in a place to provide the services that would be required to build it," said Sean Evans of Ellis Don.
