REQUEST FOR INFORMATION #1
SOLICITATION 12905B22Q0022
| Question 1 |
| …who is the manufacturer and model number of the HVAC system? Not the QCOM control system. |
| Response |
| CoolAir is the manufacturer and NBF36L is the model number for the main circulation fans for greenhouses 1-4. (SPECS for the fan are NBF fan, 1 HP, 460/3P/60HZ,) |
| Question 2 |
| Are the 4 HVAC controllers (Not HVAC itself) and the single Translator the only equipment to be replaced? May be the software manager is well? |
| Response |
| The contractor shall determine the equipment, and software necessary to provide environmental control to four greenhouses including, but not limited to sensors, software and training of up to five lab personnel. |
| Question 3 |
| We will need to know the interconnection between the four controllers and the four HVAC systems in use assuming all four HVAC systems are in a good condition and do not need to be replaced. |
| Response |
| The greenhouse control system is interconnected with low voltage telecommunications wire. The greenhouse CoolAir fans are 460/3P/60HZ and controlled by the existing greenhouse control system. |
| Question 4 |
| Is my understanding for this bid correct? |
1. Replacing the 4 controllers inside 4 control cabinets on wall, but not the metal cabinets.
1. Replacing the single broken translator unit mounted on wall.
1. Replacing the management software if necessary.

| How many sensors and the types of sensors (temperature, humidity, CO2, light, digital or analog, etc.) in each greenhouse? |
| Response |
| There is a total of 1/EA of each of those sensors in greenhouses 1-4. Digital and analog functionality is is not my area of expertise so I cannot tell you if they are digital or analog. |
| Question 6 |
| (Is a) List of all HVAC control points (i.e. heater on/off, cooling on/off, humidifier on/off, de-humidifier on/off, etc.)…possible? |
| Response |

| Question 7(a) |
| My question was related to the control interface standard that our controller will need to support and control the HVAC. It would be easier for me to find the interface connections if I know the model number. |
| Response |
| This will be a stand alone system, As stated in the scope of work the computer (control interface) will be furnished by the government. The contractor will be providing any and all equipment required to complete the project including, but not limited to sensors, software, and training of up to five lab personnel. |
