Minnesota-based C,G and B will replace the soggy turf in the Metrodome at a cost of $470,000.
Environmental studies of the Metrodome field found the turf suffered from six months of exposure to the elements while the roof was open, following a December collapse.
"We have some biological agents within the turf. Not to a huge extent, but it's something we need to deal with, and the recommendation is that we replace the field," Steve Maki, head of facilities and engineering for the Metropolitan Sports Facilities Commission.
The job begins with removal of the old turf as early as next week. The replacement turf is scheduled to be ready for an open house that will feature monster trucks, Vikings alumni and other attractions from 2 to 5 p.m. August 20.
Commission officials are submitting an insurance claim for the turf replacement to FM Global. They expect it will be covered along with the rest of the $23 million cost of restoring the Metrodome.
