PREMIER Center Pour Time Lapse

January 13, 2014, 4:57 PM by Matt Holsen

PREMIER Center Pour Time Lapse

This past weekend, crews spent hours pouring concrete over miles of pipes that will go underneath the Denny Sanford PREMIER Center's NHL-sized ice rink. The pour was continuous and there wasn't room for error.

It took five hours to pour 1.36 million pounds of concrete.  After a flatness check using lasers, Mortensen Construction superintendent Brian Boe says this floor is more level than expected.

"In my experience, it's up there. It definitely exceeded the specs," Boe said.

It took 30-crew members and 40-truck loads of concrete.  Everything went as planned beginning at 7 o'clock Saturday morning.

"What they'll see on the time lapse is really where we started and just working from west to east. Then, right after that, seeing a bunch of people on their hands and knees and then hitting it many, many times. To get a flat floor you need to get on it at the right time and you need to work it," Boe said.

Now that the concrete is poured, crews will keep it wet for about nine days.

"That helps strengthen the concrete. So we'll do that for another nine days or so and then dry cure it, just basically, open it to the elements for another 18 days," Boe said.

Even when it's open to the elements, the fresh concrete will be covered with plywood.  No one will be allowed to touch it until those 28 days have passed.

"I tell people to stay out of here. So, if they need to come in here, they talk to me," Boe said.

There will be plenty of time to see the finished product in the future.

The PREMIER Center is scheduled to open in the fall of this year.

KELOLAND TV set up a camera to record the concrete pour.  Watch that time lapse below.

The city also monitored the project.  Watch that time lapse below.
