SIOUX FALLS, S.D. (AP) — Crews at a new Sioux Falls arena under construction will be pouring the concrete ice floor this weekend.

KELO television reports that the piping has already been installed for the ice floor at the Denny Sanford Premier Center, and 25 to 30 people are covering with concrete on Saturday. The precise process involves grading the ground with lasers, pouring the concrete using lasers and rechecking it using lasers.

Mortensen Construction superintendent Brian Boe says timing is important to ensure that the slab is extremely flat to result in a consistent ice surface.

Boe is supervising the continuous pour, which will take six to seven hours.

The pour was originally scheduled to begin in February, but arena construction is ahead of schedule.
