SOL. 1232SA26R0028 - RFI'S WITH RESPONSES - 002 - V2.pdf

This is a Questions and Answers document for federal contract solicitation 1232SA26R0028 titled "NAL CHILLER REPLACEMENT."

The document addresses four inquiries submitted by a contractor regarding the chiller replacement project. Question 1 addresses the reusability of existing raceways, power/control conduit, and feeders for new chillers, with the response confirming reuse is acceptable if components are in good condition, otherwise USDA/NAL should be notified. Question 2 requests clarification on whether an existing breaker may be reused and asks for electrical characteristics of the proposed new chiller. The response confirms reuse is possible pending condition notification and provides electrical specifications including 460/3/60.0 volt power supply, 250.2 kW total input power, 395.0 A minimum circuit ampacity, 700.0 A maximum circuit breaker amps, 316.0 A job full load amperage, and 100 kA unit short circuit withstand capacity. Question 3 inquires whether one boiler may be temporarily removed from service to facilitate removal of the old chiller and installation of the new unit, with maximum downtime limitations. The response permits limited downtime removal but requests specification of the maximum allowable downtime duration. Question 4 requests contact information for the Purchasing Agent, which was not included in Section 4.0 Key Personnel of the Statement of Work. The response indicates the Purchasing Agent is not listed in the SOW and therefore contact information cannot be provided as "N/A."
