VA Response: Please confirm whether the contract scope includes all required I/O hardware, Red Lion HMI or communications-platform upgrades, programming, graphics, and Master Control Panel/SCADA modifications necessary to provide a complete and operational propane-system interface. VA Response: � Contractor shall furnish and install an electro mechanical gas shut off valve (Maxon or approved equal)� upstream of the fuel pressure regulator� and� downstream of the gas filter/strainer� to protect the downstream safety shut off valves.� The VA will provide at least one additional I/O module in the Boiler Plant Master control panel which will control the propane gas shut off valve.

The VA will provide the additional I/O prior to the completion of the contract work. RFI 7 - Boiler No. 2 Human-Machine Interface During the recent walkthrough, it was observed that the Boiler No. 2 control cabinet no longer has a functional Human-Machine Interface (HMI). A working HMI is required to interface with the existing MicroMod loop controllers and to configure, monitor, start up, test, and commission the Boiler No. 2 combustion-control system. A direct hardware swap is not adequate because current Red Lion models do not duplicate the obsolete unit's side-button arrangement; the existing screens and graphics must be re-engineered and converted for the new display. Requested VA Response: Please confirm whether the contract scope will be revised to include furnishing, engineering, programming, graphics conversion, installation, integration, testing, and commissioning of a new Red Lion HMI compatible with the existing MicroMod loop controllers and associated boiler-control equipment. Supporting Information: See Attachment E - Boiler No. 2 HMI Replacement. VA Response: The VA will have a new HMI installed prior to the completion of the contract work.
