They are not celebrating, but you can find construction workers raising the roof at the Denny Sanford PREMIER Center. The roof is nearing completion, and the project is almost fully enclosed
"To watch the process, it's been fun," Jason Miranowski with Mortenson Construction said.
Miranowski said crews should finish the center's roof by November. Workers erected six roof trusses. They're 270 feet long, and each weighs 100 tons. Each truss started out in two pieces, and cranes lifted them separately. Workers did what is called a mid-air splice to put the pieces together. Just one truss takes about 12 hours to put up.
Beyond the physical labor, a lot of planning went into the design. Miranowski said the roof had to be high enough to allow many kinds of events in the facility. For example, there is enough space to pull up the center-hung score board.
"Which allows arena football to play. Because obviously when you're kicking a field goal or throwing a football, you need to be able to have the elevation," Miranowski said.
Crews have already begun interior work, including a newly-installed escalator. When the roof is finished, they will start dry walling, painting and all of the other details needed before the grand opening.
"Then we basically go full steam ahead," Miranowski said.
The $115 million, 12,000 seat structure is on schedule to open in the Fall of 2014 and it is also on budget, according to the City.
