Sioux Falls, SD
Months of planning have gone into what will be taking place at the Denny Sanford PREMIER Center this weekend. With all the piping installed for the ice floor, 25 to 30 crew members will now take great care in covering it with concrete.
Now that the Denny Sanford PREMIER Center is fully enclosed and miles of heating and cooling pipes for the ice hockey floor are in place, it's time for the next step. At 7 o'clock on Saturday morning, the concrete pour will begin and crews have one shot to get it right.
"Timing is important in making sure the slab is as flat as it needs to be because it needs to be extremely flat in order to make this ice consistent," Mortensen Construction superintendent Brian Boe said.
Boe will supervise the continuous pour which will take six to seven hours. He's in charge of coordinating everything down to the 40 trucks carrying 1.36 million pounds of concrete. Boe will have plenty of help. City engineer Terry Van Dyke is part of the team making sure things run smoothly because there's no room for error.
"There is no room, no. We've had other projects. We went and visited one in Lincoln. I won't go into detail; they had a lot of problems. They got on the slab too early with the equipment and had some flatness issues," city engineer Terry Van Dyke said.
Once the pour is complete, things are not over. The concrete will need to wet cure for 10 days and dry cure until 28 days later before anyone will be allowed onto it.
"The intent is to get this poured as quick as possible so that I can get other trades in behind here. Daktronics with the center-hung scoreboard, ribbon boards, corner boards. The seating, retractable seating will start here in late February. It's a good step in the right direction that's for sure," Boe said.
A step that's coming in significantly ahead of schedule.
The pour was originally scheduled to begin in February. Because the measurements are so precise, the ground has been graded with lasers, the concrete is poured using lasers and the concrete will be checked after with lasers.
