\nA32 - Yes. See A14 for the final equipment list by location.
\n
\n
\nQ33 - Existing Equipment Type – Turtle Hospital/Wet Lab Observers Area
\nThe SOW identifies four (4) failing systems in the Turtle Hospital/Wet Lab area for replacement with ductless mini-split systems. During the site inspection, we observed that three (3) of the existing units are ductless mini-split systems, while the fourth unit, located in the long room within the Wet Lab/Observers Area, is a conventional split system utilizing existing trunk-line ductwork and supply vents.
\nQuestion:
\nDoes the Government require this fourth system to be replaced with a ductless mini-split system as specified in the SOW, or would the Government accept a like-for-like replacement using a conventional split system that utilizes the existing ductwork?
\nBased on the observed configuration, a single ductless indoor head may not provide uniform air distribution throughout the length of the room, whereas the existing ducted configuration may provide more effective coverage.
\nA33 - The Wet Lab Observers Area system shall be a conventional split system tying into the existing ductwork. 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. The ductless mini-split requirement does not apply to this system. See A14.
\n
\nQ34 -Existing Equipment Specifications and Electrical Requirements
\nThe SOW identifies three (3) failing Mitsubishi 2-ton units, Model PKA-A30KA6, in the Turtle Hospital. The model number of the existing unit in the Wet Lab/Observers Area was illegible during the site inspection.
\nQuestion:
\nCan the Government provide the existing unit's electrical requirements, including voltage, phase, and available electrical capacity, as well as any relevant equipment dimensions or installation requirements for the Wet Lab/Observers Area? Alternatively, should offerors base their pricing on standard electrical and physical requirements for a comparable 2-ton replacement system?
\nA34 - The government does not have legible nameplate data for the existing Wet Lab Observers Area unit and does not have documented voltage or phase for that circuit. Offerors shall base pricing on the 3-ton split system identified in A32 and shall verify field conditions prior to installation. The existing branch circuit may be reused where adequate to serve the proposed equipment. See A36.
\n
\nQ35 -Turtle Barn – Dual-Head System Capacity and Configuration
\nThe SOW specifies a new 3-ton system with two (2) indoor heads for the Turtle Barn Aquaculture Area. During the site inspection, it was observed that the two rooms intended to receive the indoor heads are approximately 150 square feet each.
\nQuestion:
\nWould the Government permit a technical deviation from the specified 3-ton system to a 2-ton outdoor unit configured with two (2) 1-ton indoor heads, with one indoor head serving each room, provided the proposed system meets the Government's required temperature-control, performance, and operational requirements?
\nAdditionally, can the Government provide or confirm the preferred locations for the two indoor heads, the outdoor condenser, and the anticipated line-set routing/lengths for this new installation?
\nA35 - Yes. The Turtle Barn system shall be a 2-ton outdoor unit with two (2) 1-ton indoor heads, one serving each room. See A14 and A23.
\n
\nQ36 -Electrical Infrastructure and Voltage Requirements
\nThe SOW requires the contractor to verify existing electrical capacity, install new circuits as required, and coordinate electrical connections with the existing building electrical service.
\nDuring the site inspection, the on-site POC indicated that 120V power is available for the newly installed equipment but recommended using 220V equipment so that the systems operate on a uniform voltage.
\nQuestion:
\nCan the Government confirm whether adequate 220V electrical capacity is currently available at the installation locations for all five (5) systems, including the Turtle Hospital units, Wet Lab/Observers Area unit, and Turtle Barn dual-head system?
\nIf 220V circuits are not currently available, should offerors include the cost of providing new dedicated circuits, breakers, wiring, conduit, and disconnects in their pricing?
\nA36 - The government does not have documented voltage, phase, or breaker capacity at each existing installation location. Existing branch circuits may be reused where adequate to serve the proposed equipment. If the offeror proposes equipment requiring a voltage or capacity different from the existing circuit, the cost of providing the new dedicated circuit, breaker, wiring, conduit, and disconnect is the offeror's responsibility and shall be included in the firm-fixed price. Offerors shall state the voltage of the proposed equipment in their technical approach. The sole exception is the Turtle Barn installation, for which NOAA will provide a new 208V breaker and the connection to building electrical service. See A37.
\n
\nQ37 -Responsibility for Electrical Work
\nThe SOW includes requirements for electrical disconnects, circuit protection, wiring, and conduit associated with the HVAC installations.
\nQuestion:
\nFor the new installation in the Turtle Barn Aquaculture Area, as well as the replacement systems, is the contractor responsible for providing all required electrical work, including new circuits and connections to the existing electrical service, or will NOAA provide/perform any portion of the required electrical work?
\nA37 - For the Turtle Barn installation, NOAA will provide the new 208V breaker and connection to the building electrical service. All other electrical work is the contractor's responsibility and shall be included in the firm-fixed price, including disconnects, wiring, conduit, conductors, grounding, and any modification required to serve the replacement equipment. The contractor shall verify existing electrical capacity as required by the SOW.
\n
\nQ38 -Disposal of Existing HVAC Equipment
\nThe SOW states that old HVAC appliances shall be turned over to the NOAA Project Lead for disposal. At the same time, the turn-key requirements state that the contractor shall remove and legally dispose of construction debris and excess materials.
\nQuestion:
\nPlease clarify the contractor's responsibility for the existing HVAC equipment. Specifically, will the contractor be required only to remove the equipment and transport it to a designated on-site location for NOAA disposal, or will the contractor be responsible for refrigerant recovery and off-site disposal/recycling of the HVAC equipment and associated materials in accordance with applicable EPA and environmental requirements?
\nA38 - The contractor shall perform refrigerant recovery in accordance with EPA regulations, remove the existing equipment, and turn it over to the NOAA project lead at a designated on-site location. Off-site disposal of the removed HVAC equipment is the government's responsibility. All other construction debris, packaging, and excess materials shall be removed and legally disposed of off site by the contractor.
\n
\nQ39 - Coastal Corrosion Protection
\nThe SOW requires outdoor condensing units to have factory- or field-applied coastal corrosion protection suitable for a marine environment and applied in a manner that does not void the manufacturer's warranty.
\nDuring the site inspection, the on-site POC also confirmed the need for protective coating due to the coastal salt-air environment.
\nQuestion:
\nDoes NOAA require a specific manufacturer, product, certification, or coating standard for the coastal corrosion protection, or will any manufacturer-approved marine-grade corrosion protection coating be acceptable?
\nAdditionally, please confirm that this requirement applies to all five (5) outdoor units, including the Wet Lab/Observers Area system if a conventional split system is approved as an alternative.
\nA39 - No specific manufacturer, product, certification, or coating standard is required. Any factory-applied or manufacturer-approved marine-grade corrosion protection coating suitable for a coastal environment is acceptable, provided it does not void or reduce the manufacturer's warranty. Coastal corrosion protection is required on both indoor and outdoor units for all five (5) systems, including the Wet Lab Observers Area condensing unit and its matched indoor unit. This expands the Statement of Work requirement, which addressed outdoor condensing units only, and is incorporated by this amendment. See A6.
\n
\nQ40 -Working Hours and Facility Access
\nThe SOW states that normal working hours shall be coordinated with the NOAA Project Lead and that work outside normal business hours may require prior written approval.
\nQuestion:
\nPlease confirm the standard working hours permitted for HVAC installation activities, particularly noisy or disruptive work, at the Wet Lab/Turtle Hospital and Turtle Barn facilities.
\nAre there any restrictions on weekend, evening, or after-hours work due to ongoing animal care and operations at these facilities?
\nA40 - Normal working hours are 8am to 5pm Central Time, Monday through Friday, excluding federal holidays. Work outside those hours requires prior written approval coordinated through the NOAA project lead. Noise-generating work in or adjacent to animal holding areas shall be scheduled in advance with the project lead.
\n
\nQ41 -Preventive Maintenance Period of Performance
\nThe solicitation identifies a base year for installation/repairs followed by four (4) option years for quarterly preventive maintenance. The CLIN structure appears to extend through Option Year 4.
\nQuestion:
\nPlease confirm whether preventive maintenance is required for a total of four (4) option years following the base year, resulting in a total contract period of five (5) years (Base Year + Option Years 1–4), or whether the Government intends preventive maintenance to cover a different period.
\nA41 - Confirmed. Preventive maintenance is required for four (4) option years following the base year, for a maximum total contract period of five (5) years. Option years are exercised at the government's sole discretion.
\n
\nQ42 - Submission of Alternate Technical Approach
\nIf the Government permits the technical alternatives described above—such as using a conventional ducted split system for the Wet Lab/Observers Area and adjusting the Turtle Barn system capacity—please clarify how these alternatives should be reflected in the quotation.
\nQuestion: Should offerors:
\nProvide pricing based on the original SOW requirements as the base proposal and separately provide pricing for the proposed alternate technical approach; or
\nSubmit pricing based solely on the approved alternate approach, accompanied by a technical narrative and justification?
\nPlease also confirm whether any proposed deviation should be specifically identified as an exception or alternate in the technical proposal.
\nA42 - Offerors shall quote to the corrected equipment configuration in A14, which is incorporated by this amendment and supersedes the equipment descriptions in the Statement of Work, the CLIN 0001 description, and the combined synopsis. Separate alternate pricing is not required, and offerors should not submit pricing to the original Statement of Work descriptions. Any remaining proposed deviation from the corrected requirement shall be clearly identified as an exception in the technical approach.
\n
\nAbout preventive maintenance
\nQ43 -Preventive Maintenance – Base Year, Option Years, and Payment: Please confirm whether quarterly preventive maintenance is required during the Base Year or begins with Option Year 1, and whether the preventive maintenance will be paid per service visit or at a fixed annual amount under the applicable CLIN.
\nA43 - Quarterly preventive maintenance is required during the base year. Per the Statement of Work, preventive maintenance begins following final acceptance of the initial installation and is performed quarterly through the end of the base period, and continues through each successive exercised option year. Each option year includes four (4) quarterly visits as stated in the applicable CLIN.
\nBecause the base period runs one year from date of award and initial installation is not due until 12/31/2026, offerors shall price three (3) quarterly preventive maintenance visits in the base year.
\nPreventive maintenance shall be priced as a fixed annual amount under the applicable CLIN. Invoicing shall occur in arrears following each completed quarterly visit, in equal installments of that annual amount. All visits shall be coordinated with the Galveston Facility Manager at least five (5) business days in advance and performed during normal business hours unless otherwise approved.

\nQ33 - Existing Equipment Type – Turtle Hospital/Wet Lab Observers Area
\nThe SOW identifies four (4) failing systems in the Turtle Hospital/Wet Lab area for replacement with ductless mini-split systems. During the site inspection, we observed that three (3) of the existing units are ductless mini-split systems, while the fourth unit, located in the long room within the Wet Lab/Observers Area, is a conventional split system utilizing existing trunk-line ductwork and supply vents.
\nQuestion:
\nDoes the Government require this fourth system to be replaced with a ductless mini-split system as specified in the SOW, or would the Government accept a like-for-like replacement using a conventional split system that utilizes the existing ductwork?
\nBased on the observed configuration, a single ductless indoor head may not provide uniform air distribution throughout the length of the room, whereas the existing ducted configuration may provide more effective coverage.
\nA33 - The Wet Lab Observers Area system shall be a conventional split system tying into the existing ductwork. 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. The ductless mini-split requirement does not apply to this system. See A14.
\n
\nQ34 -Existing Equipment Specifications and Electrical Requirements
\nThe SOW identifies three (3) failing Mitsubishi 2-ton units, Model PKA-A30KA6, in the Turtle Hospital. The model number of the existing unit in the Wet Lab/Observers Area was illegible during the site inspection.
\nQuestion:
\nCan the Government provide the existing unit's electrical requirements, including voltage, phase, and available electrical capacity, as well as any relevant equipment dimensions or installation requirements for the Wet Lab/Observers Area? Alternatively, should offerors base their pricing on standard electrical and physical requirements for a comparable 2-ton replacement system?
\nA34 - The government does not have legible nameplate data for the existing Wet Lab Observers Area unit and does not have documented voltage or phase for that circuit. Offerors shall base pricing on the 3-ton split system identified in A32 and shall verify field conditions prior to installation. The existing branch circuit may be reused where adequate to serve the proposed equipment. See A36.
\n
\nQ35 -Turtle Barn – Dual-Head System Capacity and Configuration
\nThe SOW specifies a new 3-ton system with two (2) indoor heads for the Turtle Barn Aquaculture Area. During the site inspection, it was observed that the two rooms intended to receive the indoor heads are approximately 150 square feet each.
\nQuestion:
\nWould the Government permit a technical deviation from the specified 3-ton system to a 2-ton outdoor unit configured with two (2) 1-ton indoor heads, with one indoor head serving each room, provided the proposed system meets the Government's required temperature-control, performance, and operational requirements?
\nAdditionally, can the Government provide or confirm the preferred locations for the two indoor heads, the outdoor condenser, and the anticipated line-set routing/lengths for this new installation?
\nA35 - Yes. The Turtle Barn system shall be a 2-ton outdoor unit with two (2) 1-ton indoor heads, one serving each room. See A14 and A23.
\n
\nQ36 -Electrical Infrastructure and Voltage Requirements
\nThe SOW requires the contractor to verify existing electrical capacity, install new circuits as required, and coordinate electrical connections with the existing building electrical service.
\nDuring the site inspection, the on-site POC indicated that 120V power is available for the newly installed equipment but recommended using 220V equipment so that the systems operate on a uniform voltage.
\nQuestion:
\nCan the Government confirm whether adequate 220V electrical capacity is currently available at the installation locations for all five (5) systems, including the Turtle Hospital units, Wet Lab/Observers Area unit, and Turtle Barn dual-head system?
\nIf 220V circuits are not currently available, should offerors include the cost of providing new dedicated circuits, breakers, wiring, conduit, and disconnects in their pricing?
\nA36 - The government does not have documented voltage, phase, or breaker capacity at each existing installation location. Existing branch circuits may be reused where adequate to serve the proposed equipment. If the offeror proposes equipment requiring a voltage or capacity different from the existing circuit, the cost of providing the new dedicated circuit, breaker, wiring, conduit, and disconnect is the offeror's responsibility and shall be included in the firm-fixed price. Offerors shall state the voltage of the proposed equipment in their technical approach. The sole exception is the Turtle Barn installation, for which NOAA will provide a new 208V breaker and the connection to building electrical service. See A37.
\n
\nQ37 -Responsibility for Electrical Work
\nThe SOW includes requirements for electrical disconnects, circuit protection, wiring, and conduit associated with the HVAC installations.
\nQuestion:
\nFor the new installation in the Turtle Barn Aquaculture Area, as well as the replacement systems, is the contractor responsible for providing all required electrical work, including new circuits and connections to the existing electrical service, or will NOAA provide/perform any portion of the required electrical work?
\nA37 - For the Turtle Barn installation, NOAA will provide the new 208V breaker and connection to the building electrical service. All other electrical work is the contractor's responsibility and shall be included in the firm-fixed price, including disconnects, wiring, conduit, conductors, grounding, and any modification required to serve the replacement equipment. The contractor shall verify existing electrical capacity as required by the SOW.
\n
\nQ38 -Disposal of Existing HVAC Equipment
\nThe SOW states that old HVAC appliances shall be turned over to the NOAA Project Lead for disposal. At the same time, the turn-key requirements state that the contractor shall remove and legally dispose of construction debris and excess materials.
\nQuestion:
\nPlease clarify the contractor's responsibility for the existing HVAC equipment. Specifically, will the contractor be required only to remove the equipment and transport it to a designated on-site location for NOAA disposal, or will the contractor be responsible for refrigerant recovery and off-site disposal/recycling of the HVAC equipment and associated materials in accordance with applicable EPA and environmental requirements?
\nA38 - The contractor shall perform refrigerant recovery in accordance with EPA regulations, remove the existing equipment, and turn it over to the NOAA project lead at a designated on-site location. Off-site disposal of the removed HVAC equipment is the government's responsibility. All other construction debris, packaging, and excess materials shall be removed and legally disposed of off site by the contractor.
\n
\nQ39 - Coastal Corrosion Protection
\nThe SOW requires outdoor condensing units to have factory- or field-applied coastal corrosion protection suitable for a marine environment and applied in a manner that does not void the manufacturer's warranty.
\nDuring the site inspection, the on-site POC also confirmed the need for protective coating due to the coastal salt-air environment.
\nQuestion:
\nDoes NOAA require a specific manufacturer, product, certification, or coating standard for the coastal corrosion protection, or will any manufacturer-approved marine-grade corrosion protection coating be acceptable?
\nAdditionally, please confirm that this requirement applies to all five (5) outdoor units, including the Wet Lab/Observers Area system if a conventional split system is approved as an alternative.
\nA39 - No specific manufacturer, product, certification, or coating standard is required. Any factory-applied or manufacturer-approved marine-grade corrosion protection coating suitable for a coastal environment is acceptable, provided it does not void or reduce the manufacturer's warranty. Coastal corrosion protection is required on both indoor and outdoor units for all five (5) systems, including the Wet Lab Observers Area condensing unit and its matched indoor unit. This expands the Statement of Work requirement, which addressed outdoor condensing units only, and is incorporated by this amendment. See A6.
\n
\nQ40 -Working Hours and Facility Access
\nThe SOW states that normal working hours shall be coordinated with the NOAA Project Lead and that work outside normal business hours may require prior written approval.
\nQuestion:
\nPlease confirm the standard working hours permitted for HVAC installation activities, particularly noisy or disruptive work, at the Wet Lab/Turtle Hospital and Turtle Barn facilities.
\nAre there any restrictions on weekend, evening, or after-hours work due to ongoing animal care and operations at these facilities?
\nA40 - Normal working hours are 8am to 5pm Central Time, Monday through Friday, excluding federal holidays. Work outside those hours requires prior written approval coordinated through the NOAA project lead. Noise-generating work in or adjacent to animal holding areas shall be scheduled in advance with the project lead.
\n
\nQ41 -Preventive Maintenance Period of Performance
\nThe solicitation identifies a base year for installation/repairs followed by four (4) option years for quarterly preventive maintenance. The CLIN structure appears to extend through Option Year 4.
\nQuestion:
\nPlease confirm whether preventive maintenance is required for a total of four (4) option years following the base year, resulting in a total contract period of five (5) years (Base Year + Option Years 1–4), or whether the Government intends preventive maintenance to cover a different period.
\nA41 - Confirmed. Preventive maintenance is required for four (4) option years following the base year, for a maximum total contract period of five (5) years. Option years are exercised at the government's sole discretion.
\n
\nQ42 - Submission of Alternate Technical Approach
\nIf the Government permits the technical alternatives described above—such as using a conventional ducted split system for the Wet Lab/Observers Area and adjusting the Turtle Barn system capacity—please clarify how these alternatives should be reflected in the quotation.
\nQuestion: Should offerors:
\nProvide pricing based on the original SOW requirements as the base proposal and separately provide pricing for the proposed alternate technical approach; or
\nSubmit pricing based solely on the approved alternate approach, accompanied by a technical narrative and justification?
\nPlease also confirm whether any proposed deviation should be specifically identified as an exception or alternate in the technical proposal.
\nA42 - Offerors shall quote to the corrected equipment configuration in A14, which is incorporated by this amendment and supersedes the equipment descriptions in the Statement of Work, the CLIN 0001 description, and the combined synopsis. Separate alternate pricing is not required, and offerors should not submit pricing to the original Statement of Work descriptions. Any remaining proposed deviation from the corrected requirement shall be clearly identified as an exception in the technical approach.
\n
\nAbout preventive maintenance
\nQ43 -Preventive Maintenance – Base Year, Option Years, and Payment: Please confirm whether quarterly preventive maintenance is required during the Base Year or begins with Option Year 1, and whether the preventive maintenance will be paid per service visit or at a fixed annual amount under the applicable CLIN.
\nA43 - Quarterly preventive maintenance is required during the base year. Per the Statement of Work, preventive maintenance begins following final acceptance of the initial installation and is performed quarterly through the end of the base period, and continues through each successive exercised option year. Each option year includes four (4) quarterly visits as stated in the applicable CLIN.
\nBecause the base period runs one year from date of award and initial installation is not due until 12/31/2026, offerors shall price three (3) quarterly preventive maintenance visits in the base year.
\nPreventive maintenance shall be priced as a fixed annual amount under the applicable CLIN. Invoicing shall occur in arrears following each completed quarterly visit, in equal installments of that annual amount. All visits shall be coordinated with the Galveston Facility Manager at least five (5) business days in advance and performed during normal business hours unless otherwise approved.
