of the rink floor, dasher board system, cooling tower and reinsulation of the low pressure receiver. The budget for this project is $527,500. The City is aware that the price and availability of steel piping will likely increase the cost of the floor replacement. The ice rink floor is the standard 85' x 200' see with a sand base and starting to show its age. The e�erior of the steel pipe is apparently severely pitted and corroded. Leaks in the pipe couplings at the header pipes have been on-goir�� since the original installation. There is some evidence that frost is or was present at one fime beneath the ice rink floor because the floor is settling in the middle. One reason for this settling may be that the frost was not removed completely during the renovation in 1979-1980 when the construction schedule was reportedly accelerated. The frost may have gradually been removed once the sub floor heating system was operating under the new ice rink floor. The existing dasher board system was installed during the 1979-1980 reconstruction project and is constructed of wood framing, and polyethylenecap rail, facing and kick plate. The spectator shielding is acrylic material. The existing system takes a great deal of maintenance to maintain and repair every year due to iis age. The existing mechanical room does not have the safety devices that are required by the currentinternational building codes. There is no mechanical ventilationsysfem, refrigeranf leak' detection system, or an exterior power shunt trip for emergency shutdown of the system. Improvemer��s to this room are not part of this project. a� - • ��- [�a. Our proposed scope of services is as follows: Task 1 - P��*ri*�y Design: Our services during the preliminary design phase will include: ■ PerForming a site visit to collect all additional information required for the design " Review the recommendations in the Evaluation Report dated March 26,2006. ' Discuss options for improving and replacing the existing ice rink floor, dasher board system, cooling tower and reinsulation of the low pressurereceiver including: o Renovations to the existing direct refrigerationice rink floor including options for rink piping materials, insulation materials and sub-floor heating system. o Comparison to changing the ice system to an indirect system including replacement of the refrigeration system and ice rink floor. The comparison will include: the option for re-using the existing compressors; �ypes of refrigerants available and phase out schedule of HCFC refrigerants such as R-22; Types of conventional (electricdriven)indirectrefrigerationsystemsincluding, description of each system, equipment options, floor materials, and brines.
