The associated Product Service Code is J041 Maintenance, Repair, and Rebuilding of Equipment Refrigeration, Air Conditioning, and Air Circulating Equipment. Description of Requirement: The Richard L Roudebush VA Medical Center has a requirement for preventative maintenance on five centrifugal liquid York chillers, their associated variable frequency drives (VFDs), and monitoring refrigerant leakage from the same chillers. A firm-fixed price service contract with a 1-year base period and two 1-year option periods is anticipated. The base period of performance is anticipated to be November 1, 2026 October 31, 2027. All work will occur at the Richard L. Roudebush VA Medical Center (RLRVAMC), 1481 W. 10th Street, Indianapolis, IN 46202. The facility has a primary/secondary chilled water loop to provide cooling medium for the majority of the air handling units (AHUs) and fan- coil units that distribute cool air to the interior of the buildings. The chiller plant is the sole source of cooling for the facility and has four (4) 1,000-ton and one (1) 500-ton chiller located in Building 23. All chillers are manufactured by York. The variable frequency drives associated with these 1,000-ton chillers are manufactured by Toshiba. The VFD for the 500-ton chiller is manufactured by York. The chillers and drives are all of the mid 1990s vintage. Required maintenance tasks are as follows: Preventative Maintenance / Service Tasks: Preventative Maintenance Tasks are required both Quarterly and Annually.
