Statement of Need

Background:

The North Florida/South Georgia VA Healthcare System, Lake City VA Medical Center located at:

619 S Marion Ave Lake City, Florida has an emergency Brand Name or Equal requirement for One (1) Air-Cooled Chiller to replace the current Air-Cooled Chiller servicing the Community Living Center Building 82. This replacement is due to the mechanical failure(s) and is non-repairable.

Objective:

Disconnect and remove old chiller and relocate to a specified on-site location for temporary storage. Deliver and install the new chiller on the concrete pad and connect to the current electrical and chilled Water systems.

Kick Off Meeting: TBD after award: Conduct site visit with the Contracting Officer (CO) and Facilities Management Point of Contact (POC) prior to removal of old chiller and discuss installation of the new chiller to verify utilities, connection point sizing, and current concrete slab dimensions.

Scope:

• Disconnect existing chiller to include all mechanical and electrical utilities.

• Deliver 200-ton air cooled chiller.

• The new chiller to be installed on the old chiller concrete pad south of Building 82.

• Expand and upgrade current concrete pad as needed to support the new Chiller.

• Contractor reconnects the new chiller to the current chiller water piping.

• Provide and install Chilled water isolation and bypass valves.

• Contractor runs electrical wires and connects to current electrical transformer.

• Provide and install an electrical disconnect at the Chiller.

• Connect chiller to the Siemens Desigo Building Automated System (BAS).

• Connect to BAS using BACnet (BCI-C) Communication Interface

• Chiller must be operated and monitored via BAS.

• Setup Chiller to run via the BAS.

• Provide chiller programming in the BAS.

• Provide graphics for the chiller in the BAS.

• Provide for chiller alarms in the BAS.

• Test Operation of Chiller

• Ensure the Chiller maintains proper chiller water temperature, flow, and differential pressure to provide optimum Chiller performance and maintain building 82 temperatures.

• Put the Chiller into operation and commission.

• Provide all documentation to the Contracting Officer (CO) and the POC. Also, provide an electronic version of the documentation including warranties and guaranties.

NOTE: Salient Characteristics of Air-Cooled Chiller requested are based on current equipment on- site: Trane RTAF-200
