The construction company building the Vikings stadium requested mediation Thursday with the Minnesota Sports Facilities Authority to address $15 million in disputed costs.

M. A. Mortenson Company contends it shouldn't be responsible for outstanding change orders to the construction of U.S. Bank Stadium in Minneapolis. The issue was not resolved through previous negotiation, the company said.

The company also issued a formal demand for arbitration, but both sides noted mediation is required by contract before arbitration can begin.

The MSFA counters the agreement for stadium construction established a guaranteed maximum price, ensuring Mortenson took on the risk for cost disputes.

In a statement Thursday, the Authority said the construction agreement also has a built-in contingency of nearly $29.7 million.

Mortenson Senior Vice President John Wood said the extra work was directed by the MSFA.
