- THIS IS NOT A SOLICITATION ANNOUNCEMENT. THIS IS "SOURCES SOUGHT" ANNOUNCEMENT. ANY RESPONSE TO THIS SOURCES SOUGHT WILL BE USED BY THE GOVERNMENT AS MARKET RESEARCH, FOR INFORMATIONAL PURPOSES AND TO MAKE APPROPRIATE ACQUISITION DECISIONS. The General Services Administration located in Washington DC, is looking for qualified vendors capable of performing the work as listed below. Background Information: The General Services Administration Central Heating & Refrigeration Plant (GSA CHRP) provides steam and chilled water to over 100 government facilities in the Washington DC area. At the Central Plant, HOTD operates eight (8) Johnson Controls (formerly York International) chillers and two surface condensers. The chillers and surface condensers are critical to HOTD's mission of producing chilled water to its customers and should be maintained to prevent failure due to mechanical or electrical faults which result in downtime and production losses. The eight (8) chillers of interest include seven (7) R-134a chillers and one (1) R-22 chiller (Chiller #4A). Also, six (6) of the eight chillers are electrically driven while two are steam driven. Operational inspection and preventative maintenance (PM) of the chillers and surface condensers will help to alleviate problematic faults caused from wiring and electrical connections, compressor motor malfunction and inefficiency caused by physical degradation from wear and tear on the mechanical components of the chillers. Performing preventative maintenance of the chillers and their associated systems will provide historical data on each chiller, benefitting both technicians and engineers alike. This will help to track maintenance on each chiller and highlight system problems as they develop, thus increasing chiller reliability and facilitating continuous chilled water production. Synopsis: The General Service Administration's Heating Operation and Transmission District seeks information from vendor's in the market who are capable of performing and or providing the following as it pertains to the plant's 2000 ton chillers, compressors surface condensers and auxiliary equipment; •1) Emergency response line 24 hours a day •2) Weekly Preventive Maintenance (Weekly Operational Inspections) •3) Emergency Service Calls •4) Annual Preventive Maintenance (Inspection and PM) •5) Incidental Repair of Chillers and Chiller Related Equipment The reliable and optimal operation of the chillers and associated equipment requires constant maintenance, repair and monitoring. Weekly inspections and Annual Preventive Maintenance of the chillers and their auxiliary equipment shall highlight problems and provide solutions to ward off equipment malfunction and inefficient use of energy in meeting the cooling load. Chiller system maintenance will help to ensure the refrigeration system meets a high-level of performance that is in-line with the expectations of the Government and is based on manufacturer design, system design and GSA operating conditions. These chillers are operated 2 to 3 at a time in the winter and up to 7 at a time in the summer months. Project Specifics: General Maintenance: maintenance practices shall total fifty-two (52) visits to the plant per year for weekly inspections and operational checks and once a year for annual preventive maintenance of chillers and chiller related systems. All work is to be carried out by a technician or personnel who has received training from Johnson Controls to work on Johnson Controls (York) 2,000 ton capacity chillers and greater. Emergency Service Calls and Response: In the event of an unexpected chiller breakdown, such as a chiller failing to start or load, unusual noise, nuisance warning lights and alarms, a vendor must have the ability to provide emergency service response within 4 hours and attempt to get the chillers back in stable operating condition to meet the required load. The vendor shall have the ability to provide emergency response service that shall be available 24 hours a day, 7 days a week for 365 days. Anticipated Period of Performance: The anticipated period of performance for this requirement is five (5) years, consisting of a one-year base period plus four (4) one-year option years. Capability Requirements / Sources Sought: We are looking for vendors who have the following capabilities: - Can demonstrate the ability to meet the mandatory criteria as noted above. •2. - Who have all of the following: •· Experience with industrial chillers greater than 1000 tons. •· Experience with auxiliary chiller system equipment and devices including valves, actuators..etc. •· Experience providing service for an operation heavily dependent on changing weather patterns. •· Experience in demonstrating an understanding of the equipment associated with industrial chillers. •3. - Who have qualified staff on board, experienced and trained to work with the tools needed to perform this type of work. •4. - Ideally we are looking for vendors who have the following type of personnel on staff or personnel who have similar qualifications. •a) Chiller Service Project Manager will have at least five (5) years experience as a chiller service project manager and coordinating supervisor, eligible to manage a project of this magnitude.
