On A Mission For example, the inn was blowing circuits every year during the annual Festival of Lights. Elimination of the central plant within the hotel p ,l gi complex, along with its associated power requirements, restored approximately 600 A for use in the hotel for lighting and other power requirements. General contracting activities included laying the required footings, the slab-on-grade foundation, and an equipment pad for Riverside Public Utilities’ transformer and associated switch gear, and plumbing for makeup and drain systems. Additional mechanical system contracting activities included provision for trenching, including required break, removal, excavation, backfill, and paving from the central plant to the existing point of connections (POC) at the old chiller plant. The existing tunnel was utilized for the new chilled water piping to the POC. Aboveground, chilled water piping was installed from the new chiller plant to the POC. Condenser water supply and return piping was installed to connect to the new cooling tower system. The modular central plant was completed with piping for chilled water, fancoil units, and water treatment equipment. The shutdown of the existing central plant and cutover to the plant was scheduled for an evening in June. Crossover piping had already been laid to transfer the plant into the existing piping, making it a smooth transition. Throughout the project, minimizing the impact of the work on the Inn’s guests, as well as the other businesses in the area, was a priority. Coordination, cooperation, and detailed planning were essential in meeting that goal. As working partners in the project, the owner, Mesa, the City of Riverside and Riverside Public Utilities, the architect, and subcontractors were on a mission to complete the project in time for the peak cooling season, and the fast-track project drew to a successful close.
