Title
Informational Report on the Larson Ice Center Ice System Replacement.
Body
Summary:
Ubl Design Group, in collaboration with the Parks, Recreation and Forestry Department, wishes to provide information to the City Council pertaining to the need and feasibility of options for replacement of the ice system at the Larson Ice Center.
Introduction:
The primary focus is to evaluate the ice system replacement options along with other factors pertaining specifically to Larson Ice Center that will influence the recommended choice of system to move forward with. Factors include: building usage, constructability, building operations, phasing strategies, scheduling, financing and long-term sustainability.
Building Background -
Larson Ice Center opened in 2002 and consists of two regulation sized ice sheets and a holding barn. The building square footage is approximately 75,600 SF. The current ice system type is an R22-Indirect/Glycol system. The life expectancy of this type of system is approximately 20-25 years. Due to a handful of concerns, the Larson Ice Center ice system is failing and outside professional recommendations state that the ice system and ice rink floors be replaced as soon as feasibly possible.
Groundwater Mitigation -
The consultant has identified that wet and saturated soils exist just below the rink floors, which has led to the failure of the steel piping system. It is believed that the heave in the Red Rink floor reflects the wet soils under the rink floor freezing during the ice season. The consultant recommends installing a water mitigation system under the new rink floors and upgrading water mitigation issues on the entire site including the parking lots and roof drainage.
Ice System -
Based on the assessment, three primary issues need to be evaluated in determining a replacement system.
1. The heat exchanger has failed and needs replacement. The cost for this replacement is between $44,000 to $50,000. Note: replacing the current heat e...
