- Description
- The U S Environmental Protection Agency (U.S. EPA), National Environmental Research Laboratory in Athens, Georgia, intends to award a fixed-price Purchase Order using Federal Acquisition Regulation (FAR) Part 13, Simplified Acquisition Procedures. The purpose of this acquisition is to acquire a one-year preventive maintenance agreement for two, 150 ton McQuay Centrifugal Chillers, located in EPA?s main building at 960 College Station Road, Athens, Georgia. The Statement of Work, outlining our requirements, is attached after this synopsis/solicitation. This is a combined synopsis/solicitation for commercial items in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice.

Athens, Georgia 30605-2700 CENTRIFUGAL CHILLER PREVENTIVE MAINTENANCE PROGRAM BACKGROUND A. The Ecosystems Research Division is located in a three story building with a gross square footage of approximately 57,000 square feet. This building includes administrative, laboratories and offices in the first, second and basement floors. Air conditioning is provided by means of two centrifugal McQuay chillers with a capacity of 150 tons each. B. The McQuay Model PEH Centrifugal Water Chillers are complete, self-contained, automatically controlled water chilling units. Each unit contains one compressor connected to a condenser and an evaporator. The standard chillers use refrigerant 134a, to reduce the size and weight of the package and since they operate at a positive pressure over the entire operation range, no purge system is required. C. The purpose of this agreement is to establish a Centrifugal Chiller Preventive Maintenance Program, covering both predictive maintenance and air conditioning, which will provide the required service to assure the continued and satisfactory operation of the chillers. GENERAL A. The Centrifugal Chiller Preventive Maintenance Program shall cover routine inspections of the two centrifugal McQuay chillers, parts and labor, refrigerant and oil, annual cleaning of the condensers, and all emergency service 24 hours a day, 7 days per week, including holidays. Consult McQuay Bulletin No. IM307-4, January 1995 (or a more recent edition), for maintenance instructions. B. EPA shall designate a representative to receive instructions in the operation of the designated equipment who shall have sufficient authority to carry out the recommendations received from the Contractor?s service personnel in conjunction with this agreement. CONTRACTOR?S TASK A. During the term of this agreement, the Contractor shall: 1. Furnish all labor, parts, refrigerant, oil, tools, instruments, equipment and materials needed to maintain the designated equipment in good operating condition, and perform during normal working hours, unless an emergency condition exists, the maintenance service in accordance with this Centrifugal Chiller Preventive Maintenance Program. 2. Be responsible for the maintenance and the replacement of both the entire units of designated equipment, including the wiring, starters, control devices, pressure and temperature controls, thermometers, gauges, thermostats, manual valves, insulation and piping within the boundaries of the unit and inter-connnecting (power and/or control) wiring between the units. 3. Notify Technical Coordinator, Harvey Holm, at least seven (7) calendar days prior to desired scheduling of work so that any necessary arrangements on EPA?s part can be made, including the notification of the Operator to be available on the day of maintenance. Harvey Holm must be notified either by fax at 706-355-8068 or e-mail at Holm.Harvey@epa.gov. 4. Furnish a written report to Harvey Holm (via fax or e-mail) for all work performed as a part of this Program detailing the chiller?s performance during the checking or testing period, for all repair work, and any recommendations as to improved chiller performance. 5. Perform all quarterly checks during the months of January, April, July and October. 6. Perform all semi-annual checks during the months of April and October. 7. Perform the annual check during the month of April. CHECKS TO BE PERFORMED A. Monthly: (Routinely performed by operator, but Contract will complete at the time of the quarterly check.) 1.
