Solicitation 36C26322Q0463 Amendment A00001

Questions, Answers, and Clarification

1. Verify that the period of performance begins on 06/15/2022.

a. Answer: It is anticipated that the period of performance for the required work under RFQ 36C26322Q0463 will begin 06/15/2022. However, note the period of performance for certain Contract Line Item Numbers (CLINs) in section B.2 Price/Cost Schedule do not begin until after 06/15/2022.

2. Clarify the required response times in B.3 Performance Work Statement (PWS), IX Scope of Work e. Repairs or Emergency Services.

a. Answer: Subsection i., paragraph 1 (on page 23) requires the Contractor to respond to the VA within fifteen minutes. The fifteen-minute response is a phone call response. Paragraph 2 in that same subsection requires the Contractor to have a qualified technician on-site within two hours of the VA’s request at the Omaha location and within four (4) hours of the VA’s request at the Grand Island location.

3. Is chiller Model # AMZ020AMSEM0040 – Serial Number STNU200200176 in Omaha a York or Daikin-McQuay?

a. Answer: It is a Daikin-McQuay chiller. CLINs 0004, 1004, 2004, 3004, 4004 are hereby modified as noted below.

4. Is a complete oil flush required every year on each chiller (which is more than some manufacturers recommend) or should the contractor follow manufacturer’s recommendations regarding oil analysis and flushes as determined by the oil’s quality/life span?

a. The contractor should follow the manufacturer’s recommendations. Section B.2 Performance Work Statement (PWS), IX. Scope of Work, b. Preventative Maintenance, paragraph xiii shall be changed to read, “The Contractor shall perform a minimum of one inspection per contract period of performance of the oil distribution system to include cleaning of the coil cooler, and replacement of the lubricating oil removed from the on-site chiller(s), as needed.”

5. If a chiller is removed from service, would the replacement chiller be added to the contract?

a. Answer: Yes, if a chiller is replaced during the period of performance of the contract, it is expected that the replacement chiller would be covered under the contract. Such a change would be documented in a modification signed by both parties.

6. Does the awarded contractor need to meet all Qualifications listed on page 20 itself?

a. Answer: No, contractors may utilize subcontractors so long as the Limitations on

Subcontracting are met.

7. Procurement history can be researched at fpds.gov.

8. Offerors must complete and submit Section C.8 VAAR 852.219-77 VA Notice of Limitations on Subcontracting-Certificate of Compliance for Services and Construction (SEP 2021)(Deviation) with the quote.

9. Offerors must provide information indicating the offeror meets the following technical factor in addition to the price factor:

Technical Factor 1: The offeror/contractor must have personnel who possess an EPA Universal Certification. The offeror/contractor shall provide a copy of such current EPA Universal Certification with the offer to demonstrate the ability to meet this requirement of the VA.

Technical Factor 2: The offeror/contractor must be an authorized service provider for York brand chillers. The offeror/contractor shall provide information, such as a letter from the OEM, with their quote to demonstrate their ability to provide this requirement to VA.

Technical Factor 3: The offeror/contractor must be an authorized service provider for Daikin-McQuay brand chillers. The offeror/contractor shall provide information, such as a letter from the OEM, with their quote to demonstrate their ability to provide this requirement to VA.

Technical Factor 4: The offeror/contractor must be an authorized service provider for Trane brand chillers. The offeror/contractor shall provide information, such as a letter from the OEM, with their quote to demonstrate their ability to provide this requirement to VA.

FAILURE TO SUBMIT ANY OF THE REQUIRED INFORMATION, STATEMENTS, OR

CERTIFICATIONS MAY RESULT IN REJECTION OF THE QUOTE WITHOUT FURTHER

CONSIDERATION FOR AWARD.
