Workers will begin replacing the Metrodome's storm-battered roof Thursday.
Crews with Birdair Inc., the New York contractor hired by the Metropolitan Sports Facilities Commission to do the job, will spread a protective tarp over the playing field to get ready for the work above.
Clamping for roof panels will be checked Monday, and the installation of new roof panels may begin as soon as late next week.
Commissioner Ray Waldron, who chairs the commission's capital improvements committee, said that center panels will be replaced first.
The commission decided to replace the 29-year-old fiberglass roof after it was ripped open in a December blizzard.
Birdair will be paid $18 million for substantially completing the job by Aug. 1, in time for the Minnesota Vikings' preseason games.
Birdair designed and installed the roof that had covered the Dome since its opening in 1982. The new roof will be lower than the old one.
The commission will discuss the roof project at its regular monthly meeting Thursday.
