Questions & Answers / Clarifications

This document provides clarifications and answers to vendor questions regarding the solicitation.

• Buy American Act Applicability: The Buy American Act applies to this procurement. Foreign materials may be allowed if U.S.-made items are unavailable in sufficient quantity/quality, their use is impracticable, or they result in an unreasonable price. Offerors proposing foreign materials must include item description, supplier, quantity, unit price, total price, duty/delivery costs, and comparable U.S.-manufactured item details.
• Chiller Replacement Options: Two solutions are acceptable for replacing the chiller and chilled water coil, provided minimum specifications are met:
  • Solution A: Replacement of the chiller and chilled water coil with the addition of a glycol feed pump. This solution is only applicable if it is a water-cooled chiller, sized to 20 tons. Interconnection to alarms is not required.
  • Solution B: Use of a condensing unit (40-ton capacity) and replacement of the chilled water coil with an evaporator coil (20-ton capacity). This allows for redundancy.
• Existing Chiller Nameplate: A picture of the existing Carrier chiller nameplate is available as Attachment 9, posted with Amendment 001.

Section L-1, 4e) Technical Approach has been updated to reflect the acceptance of either Solution A or Solution B. Offerors must clearly demonstrate that their chosen approach meets all mandatory performance requirements. No additional credit will be given for exceeding minimum requirements. The basis for award remains lowest price technically acceptable.
