Amendment No. 2 – Solicitation No. GS-07-P-17-HT-C-0008 for Chiller Removal & Installation at the Roswell Federal Building in Roswell, NM

This amendment is issued to provide Exhibits E - F and to respond to questions. The proposal due date has been extended from 7/12/2017 to 7/17/2017 at 2:00 PM CDT.

1. Does the chiller have to be a 4 pass heat exchanger? No, but the pressure drop must be equal to or less than what is listed in the solicitation or your proposal will not be accepted.

2. Confirming that chiller is a single compressor design. The original bid description states it needs to be two compressors. These two (2) magnetic bearing chillers are a single compressor design.

3. Please provide information on existing lighting to be replaced such as controls, output, B/U capabilities, and quantity. Contractor shall remove and replace existing fixtures to match all associated existing conditions. The existing thirty (30) fixture(s) does not have controls and/or B/U capabilities. Contractor shall provide fixture factory specification cut-sheet for review and acceptance prior to purchasing materials. No linear L.E.D.’s (TLED’s) will accepted as an option for this project.

4. Please confirm existing pumps are 208v. Existing pumps are connected to a 460 volt source. The existing pumps are dual voltage 208/460 volts.

5. I do not see Exhibits e. & f. with the revised SOW. Please let me know if these were left out or can be found elsewhere. The exhibits are attached.
