About this file
This is a Statement of Work for repairs to the USDA Food Animal Environmental Systems Research Unit (FAESRU) Greenhouse/Headhouse located at 230 Bennett Lane, Bowling Green, Kentucky. The facility's building control system requires repairs to restore proper operations following a boiler replacement project that did not include replacement of two failed Solidyne SAM 25 controllers that cannot communicate with the Jace front end system.
The primary scope of work includes: (1) replacement of two existing Solidyne DDC panels with new programmable BACnet controllers, including power, wiring, programming, and commissioning while reusing existing temperature sensors; the new controllers must monitor and control Pump 2A and 2B status, boiler loop differential water pressure, Loop Pump 2A and 2B, and Loop VFD 2A and 2B for each controller; and (2) replacement of the AAON air handler reheat control board identified as an MHGRVA board. All work must comply with applicable code standards, coordinate site access with appropriate USDA personnel, and meet applicable security requirements. The complete project must be finished within 90 days after issuance of the Notice to Proceed.

Control System Repairs to Achieve Operations
Statement of Work (SOW)
The USDA FAESRU Greenhouse/Headhouse at 230 Bennett Lane, Bowling Green, KY 42104 has a building control system that requires repairs to achieve proper operations. This project is to establish proper operations through replacement of defective controllers/communications and commission to prove operations.
As reported in internal USDA email, newly replaced boilers and existing space air handling conditioning unit are requiring manual operations due to control communication failure to actuator valves and failed air handler controller. A boiler replacement project did not cover replacement of two Solidyne SAM 25 controllers which do not communicate with a Jace front end.
To achieve proper operations the following is proposed:
Replace the 2 existing Solidyne DDC panels with new programmable BACnet controllers including power, wiring, programming and commissioning reusing existing temperature sensors.
Controller 1 Pump 2A status Pump 2B status Boiler loop differential water pressure Loop Pump 2A Loop Pump 2B Loop VFD 2A Loop VFD 2B Controller 2 Pump 2A status Pump 2B status Boiler loop differential water pressure Loop Pump 2A Loop Pump 2B Loop VFD 2A Loop VFD 2B Replace AAON air handler reheat control board The board has been conveyed as a MHGRVA board.
Work is to comply with all applicable code standards, with site access coordinated with appropriate USDA personnel and applicable security requirements. All work shall be completed 90 days after Notice to Proceed (NTP) has been issued.
