Each offeror shall provide multiple selections of various equipment manufacturers (Carrier, Daikin, Trane, York), and will be asked to list on the bid form the following information for each proposal package designation: total first cost to install each option, and IPLV efficiency of the chiller at ARI 550 conditions. The life cycle cost of ownership of the chiller, including first cost, energy cost, and maintenance cost will be calculated over the 20-year life of the chiller. Lead times from release of order to jobsite arrival shall be listed on the bid form. For each chiller, and each manufacturer, submit costs for the shortest lead time chiller, the lowest cost chiller, the most efficient chiller, and the best combination of the above criteria. Each manufacturer may submit four selections meeting this criterion. Offerors shall include all options corresponding to the proposal package schedule attached. All selections shall meet the capacities in the construction documents and shall be installed in accordance with the drawings and specifications. Award of proposal packages will be based on life-cycle cost, and delivery time.
