The purpose of this amendment 0001 is to clarify CAR 1352.246-70, as well as provide an updated revised SOW and respond to the questions received for Solicitation No. 1333MF26Q0110. Combined Synopsis Solicitation: 1333MF26Q0110 CAR 1352.246-70 final inspection and acceptance will occur at the NOAA Galveston facility An updated Revised Statement of Work is included in this amendment 0001 as an attachment to the amended solicitation. Revisions are clearly identified in red font . Response to Questions: Q&A #1 Solicitation_1333MF26Q0110_FD-26-517 (Galveston HVAC repairs/Replacements) All questions were due from vendors by 10am EST 9/10 Q1-Please confirm the required nominal capacity for the three Mitsubishi PKA-A30KA6 replacements. The SOW describes these as 2-ton systems, while the model designation appears to indicate a different nominal capacity. A1 - There are two (2) 2 ton and one (1) 2 ton machines in the Turtle Hospital. Clarified in more detail for question 14. Q2-Please provide the required capacity of each indoor head serving the new 3-ton dual-head system in the Turtle Barn Aquaculture Area. A2- should be a (2) two ton unit with each head being a one (1) ton unit Q3-Please confirm the voltage, phase, available breaker capacity, and whether the existing electrical circuits may be reused. A3 - Existing circuits will be reused. The new breaker for the turtle barn will be added by NOAA, it will be a 208volt Q4-Please clarify whether the base-year CLIN must include all four quarterly preventive-maintenance visits in addition to the five-system installation. A4 - Yes, base year must include quarterly preventive maintenance. Q5-Please confirm the correct option-year CLIN numbering. The solicitation identifies the option CLINs as 0002 0005 in one section and 1001 4001 in another. A5) Option CLINS will either be 0002-0005 or 1001-4001, no final decision has been made Q6-Please identify the acceptable coastal-corrosion coating standards, approved products, and required manufacturer or warranty documentation. A6 - Both the interior and exterior units must have appropriate coastal coating to meet the Galveston Climate and proximity to the ocean/sea air. Q7-Please confirm that final inspection and acceptance will occur at the NOAA Galveston facility. CAR 1352.246-70 currently identifies the NMFS Miami campus as the place of acceptance. A7) Final inspection will occur at the Galveston Facility Q8-Please provide any site-visit measurements, photographs, attendance notes, or other information available to prospective offerors who could not attend the scheduled walkthrough. A8) All Q&A from the site visit is located within this Q&A document and Amendment to the solicitation Q9-Please clarify whether NOAA will issue tax-exempt purchasing documentation for materials incorporated into the project. A9) The Federal government does not pay taxes, however we can not dictate state and local tax requirements on vendors. NOAA will not be issuing tax exempt purchasing documentation for material purchasing, however the contract itself will be tax exempt as the Federal Government does not pay taxes. Q10-Please confirm whether monthly-equivalent pricing is required only for preventive-maintenance services or also for the one-time installation under the base CLIN. A10 - Monthly pricing is not needed for the base one time installation, that should be FFP. Q11-Would the facility like the option, on the mini split systems, to turn the heat on during the winter months, or would like the systems to be cool only? A11 - Yes, all units installed will be dual use (Cooling and Heating) as they currently are. Q12-Is there a particular brand of choice for the systems? would they like direct replacements or will a different brand work like Daikin Systems? A12: The government is relying on proposals to recommend the best solution to meet the requirements as outlined in the solicitation, statement of work and Q&A. Q13-Would the facility be ok with swapping the voltage of the systems from 110v to 208/230v in the case of the 110v/2Ton systems are not in stock. These units are particularly hard to find in a 2 ton system. A13 - The government is relying on proposals to recommend the best solution to meet the requirements as outlined in the solicitation, statement of work and Q&A. Q14-Can we get verification of the correct tonnage of each of the units? There were some discrepancy`s during the site visit. A14 - The following is the final equipment configuration by location. It supersedes the equipment descriptions in the original Statement of Work, the CLIN 0001 description, and the combined synopsis, and is incorporated by this amendment. Turtle Hospital: Three (3) ductless mini-split systems. Two (2) at 2.5-ton nominal capacity and one (1) at 2-ton nominal capacity. Wet Lab Observers Area: One (1) 3-ton split system tying into the existing ductwork. This system is not ductless. The existing ductwork will be reused. The existing coil is presumed unserviceable and shall be replaced with an indoor unit matched to the new condensing unit. Turtle Barn Aquaculture Area: One (1) new ductless mini-split at 2-ton nominal capacity with two (2) 1-ton indoor heads, one head serving each room. All five (5) systems shall be heat pumps providing both heating and cooling. All equipment shall meet the coastal corrosion protection and materials requirements of the Statement of Work as modified by A39. Where the original Statement of Work, CLIN 0001, or the combined synopsis conflicts with the above, this answer governs. Q15 - Please confirm required size of each condenser and head unit for the Turtle Hospital building. There was some confusion on what was requested vs what we were told. A15 - Answered in question 1 and 14 above Q16 - Do we need to replace all lines between inside and outside unit? A16 - The government is relying on proposals to recommend the best solution to meet the requirements Q17 - Please confirm a size on outdoor unit at the observation building. It doesn't have a tag. A17 - Based on future use it is recommended a three ton split unit. That will tie into the existing duct work. Q18 - Please confirm that duct and coil will be reused inside of observation building. A18 - The duct yes, the coil is presumed to be unserviceable. The Split unit should have an internal unit that will tie into the duct work. Q19 - New unit for Turtle Barn - does the supply power need to be included, or will it be provided by others during office construction? A19- NOAA will provide connection Q20 - Could you provide site-visit photos, equipment photos, measurements, or field notes available for review? A20 - The government does not have existing photos available for review. Vendors were advised to attend the one scheduled site visit to acquire necessary photos etc. Q21 - For the four replacement systems, should the existing refrigerant line sets be reused or replaced? If replacement is required, can approximate lengths and routes be provided? A21 - The government is relying on proposals to recommend the best solution to meet the requirements Q22 - Please confirm the existing electrical service for each system, including voltage, phase, breaker size, disconnect location, and whether the existing circuits may be reused. A22 - Existing circuits and disconnects will be reused. Vendors were advised to attend the one scheduled site visit to acquire necessary photos etc, opportunities were given throughout the site visit. Q23 - For the new 3-ton dual-head system in the Turtle Barn/Aquaculture Area, are the locations of the outdoor condenser and two indoor heads predetermined? A23 - The general locations are established. The outdoor condensing unit will be located on the exterior of the Turtle Barn, and one indoor head will serve each of the two rooms in the Aquaculture Area, each approximately 150 square feet. Exact mounting positions will be finalized with the NOAA project lead prior to installation. Offerors shall price a complete installation at these locations. Q24 - Can approximate distances and routes be provided for the refrigerant piping, condensate piping, and electrical runs for the new 3-ton system? A24 - The government does not have measured distances for the Turtle Barn installation. Offerors shall state the line-set, condensate, and electrical run lengths assumed in their pricing. Vendors were encouraged to attend the site visit to take any pictures, measurements and confirm all requirements prior to proposal. Q25 - Is gravity condensate drainage available at each indoor-unit location, or should bidders include condensate pumps? A25 - Gravity condensate lines are in use and should continue to be used. Q26 - Were any unusual access conditions, penetration requirements, mounting restrictions, or lift/scaffold requirements identified during the site visit? A26 - None Q27 - Are the existing outdoor-unit brackets, pads, and supports suitable for reuse, or should bidders include new…
