About this file
This is a Questions and Answers (Q&A) document from a federal contract opportunity for HVAC replacement services at a hatchery facility. The document does not address specific response dates, award dates, pricing terms, set-asides, or federal agencies.
The contract is a new engagement with no incumbent contractor. The existing HVAC system uses two units with model number HCDH2600-S and different serial numbers (PCPH090991 and PCPH090992), designed by Big Horn Consulting Engineers in 2009. The replacement configuration requires exterior-mounted HVAC units (RTU-style or equivalent) ducted into the building without blocking vehicle access on the south/southwest side. The facility includes Hatchery 1 with 28 four-foot diameter tanks and 6 eight-foot diameter tanks, and Hatchery 2 with 47 four-foot diameter tanks and 8 eight-foot diameter tanks. The government is relying on the contractor to determine equipment and material specifications including duct material and insulation. Current heating is adequate, but cooling ability is marginal; the facility seeks to maintain ambient air temperature between 60-75 degrees Fahrenheit (or 65-75 if 60 is unattainable) and humidity at 50% or less. The facility contains potentially corrosive chemicals including Parasite-S (Formalin), 35% Hydrogen Peroxide, Halamid (Chloramine-T), 99% Ethyl Alcohol, Earth-Tec, and Muriatic Acid. Full floor plan drawings are available, but electrical drawings are not. The government has accepted that equipment lead times make a 10-day mobilization unrealistic and will adjust the mobilization schedule to match equipment lead times. The government desires CO monitoring in tank rooms if possible and prefers maintaining existing thermostat locations in office space with remote sensing bulbs unless a better recommendation is provided.

Q: Can you provide a picture of the Name Plates for these items so I can view the model /serial numbers for these items. This would reduce the lead time of receipt of product that will meet your start date of service
A: Yes – Both model numbers are the same: Serial number are different: PCPH090991 &
PCPH090992
Q: We would like to know if this is a brand-new contract OR if there is (was) an incumbent performing these services. If not brand new, could you please provide the current / previous contract number?
A: This is a new contract.
Q: Whether existing HVAC model and serial numbers are available for reference.
A: Yes – Both model numbers are the same: Serial number are different: PCPH090991 &
PCPH090992
Q: That the intended replacement configuration is exterior-mounted HVAC units (RTU-style or equivalent) ducted into the building, as described above.
A: Yes, without blocking the ability to drive around the building on the south/southwest side
Q: Are there any specifications for equipment and materials beyond what is provided in the RFP, such as duct material, insulation, etc.?
A: No, we are counting on the contractor to determine and provide the specifications for equipment and materials needed.
Q: Are there any potentially corrosive chemicals used in the operation that we should be aware of?
A: Yes – We have Parasite – S (Formalin ) and 35% Hydrogen Peroxide on site, Halamid (Chloramine-T), 99% Ethyl Alcohol, Earth-Tec, Muriatic Acid.
Q: Are there existing drawings available for the site, including electrical and full floor plan drawings?
A: We have full floor plan drawings but do NOT have electrical drawings Big Horn Consulting Engineers, CO designed the current HVAC system in 2009. They have ACAD drawings of the existing, as builts, etc..
Q: Existing thermostats are located in the office space with remote sensing bulbs in the spaces served by the air handlers. Should this setup be maintained?
A: Yes, unless there is a better recommendation.
Q: The existing scope notes that the equipment is undersized. Are we unable to keep up with heating, cooling, humidity control, or all of the above?
A: The current heating is adequate. The cooling ability is marginal. We try to maintain ambient air temperature around 70 degreed F. It would be preferable to be able to control the ambient air temperature between 60 – 75 degrees. If 60 degrees is not attainable 65-75 would be preferred. We would like to maintain the humidity at 50% or less if possible.
Currently our humidity is around 55%
Q: Existing air handlers have external duct heaters. Please confirm if the plan is to demolish these as well.
A: If the existing heaters are not compatible with the new units they would need to be demolished and replaced.
Q: Does the space require CO monitoring?
A: Currently we do not monitor CO in the tank rooms however we would like to have this included if possible
Q: Current equipment lead times make a 10-day mobilization after NTP unrealistic.
Our recommendation is to select optimal equipment and adjust mobilization to match equipment lead times. Is this acceptable?
A: Yes
Q: On-site staff provided a count of (28) 4' diameter tanks and (12) 8' diameter tanks in the main space, and (47) 4' and (8) 8' diameter tanks in the western room. Please confirm this count.
A: Hatchery 1 (first hatchery you walk into from office) has: 28 – 4’ diameter tanks and 6 – 8’ diameter tanks.
Hatchery 2 has: 47 – 4’ diameter tanks and 8 – 8’ diameter tanks
