The construction company that the Minnesota Vikings are using to advise them on building a new stadium in Ramsey County's Arden Hills is disagreeing with a state study that said building the project by 2015 is unrealistic.

John Wood, a senior vice president for Mortenson Construction, said in a letter that while the company agreed the building schedule was aggressive, it was "very adequate". A study by the Metropolitan Council and Metropolitan Sports Facilities Commission, which was requested by Gov. Mark Dayton, concluded earlier this month that the building schedule for the $1.1 billion stadium was aggressive and may not be met. Mortenson Construction was the construction manager for both Target Field, the new home of the Minnesota Twins, and TCF Bank Stadium, the new home of the University of Minnesota's football team. The Minneapolis-based company has also provided a cost analysis for remodeling the Metrodome, the downtown Minneapolis home of the Vikings since 1982. In one noteworthy comment, Wood said the company has also advised Hennepin County, among others, "in connection with other sites under consideration for a new multi-purpose stadium." As far as the proposed stadium in Arden Hills – the Vikings preferred site – Wood added that "we have complete confidence that this can be achieved." "We are certain that you are well aware of the unprecedented unemployment level that exists in the Minnesota construction industry," he added. Dayton said he wants a special legislative session by Thanksgiving to decide the Vikings stadium issue, and said that both the Arden Hills site and other sites in Minneapolis remain possibilities.
