We conclude our project in pictures series featuring The Akervik Rink remodel project at Hobbs Ice Arena in Eau Claire, Wisconsin with the final piece: rink floor construction. As most readers may recall, this project began in late March of this year. Six months and a lot of work later, the rink was back in operation on schedule, just in time to welcome this year's skating and hockey groups. Work completed during the project included: • Replaced the rink floor and dasherboards • Rebuilt the locker rooms • Added a mezzanine viewing area • Painted the interior of the rink space • Upgraded the sound system • Installed new rubber flooring throughout the rink Work was also done to prepare for future projects at the facil- ity, but the crux of this project was centered around the rink floor replacement with the other work being done at the same time to take advantage of the down time while the rink floor was replaced. THE ISSUE Frost heave was the reason this project began in the first place, so in April, after the old rink floor was removed, an investigation was done to determine whether any ground frost remained. It was confirmed during the investigation that no more frost existed in the ground under the old rink floor, so construction of the new floor began shortly after. THE JOB First, sub-grade soil was removed and the area was laser graded and compacted to provide a level starting point at the correct height for where the finished rink f loor elevation needed to end up. Then, the subfloor heat piping system was installed and cov- ered with a layer of clean sand. The subf loor system has 3-inch header piping with approxi- mately 1.5 miles of fusion-welded 1-inch SDR-11 piping spaced 18 inches on center for f luid circulation. The subf loor piping was pressure tested for 24 hours at 100psi and once passed, the subf loor piping was covered with a layer of clean sand. That sand layer was then laser graded and compacted so that the USICERINKS.COM NOVEMBER.DECEMBER.2019 / 31 2 3
