MINNEAPOLIS (AP) — The Minnesota Sports Facilities Authority and the Minnesota Vikings hope to pick an architect for the team’s new stadium within the next three weeks.

Five architectural firms are vying to win the contract. But Sports Facilities Authority chairwoman Michele Kelm-Helgen said it’s too soon to pick from among them.

Kelm-Helgen said that all five of the firms are “really qualified.” She said “it’s a very difficult decision.”

The Vikings and the authority hope to reach consensus on an architect by the next authority meeting on Oct. 5. Both Vikings management and the authority have to agree on the choice.

The job is expected to earn the designer’s firm as much as $50 million. Groundbreaking on the $975 million downtown Minneapolis stadium is expected next year.
