Section 4: Project Background & Project Description The General Services Administration, Region 8, is initiating a project to provide and install a digital water mixing valve on the domestic hot water system at the Pierre Federal Building. Focus of the project is to provide the capability to operate the water heaters at higher temperatures to prevent the growth of Legionella and temper the domestic hot water supply to assure consistent safe hot water temperature to prevent scalding at the point of use with connection of the digital water mixing valve to the building’s BAS system for monitoring.

Section 5: Project Objectives The contractor shall provide labor, materials, equipment and supervision necessary to perform:

1) Contractor to provide and install factory built whole building mixing valve assembly on the domestic hot water systems to temper hot water supply.

a. Contractor is responsible for determining the size based on building demand and piping configuration.

i. International Plumbing Code Section 613 Temperature Control Devices and Valves 613.1 Temperature actuated mixing valves. Temperature actuated mixing valves, which are installed to reduce water temperatures to defined limits, shall comply with ASSE 1017. Such valves shall be installed at the hot water source.

ii. Contractor required to provide calculation documentation used to determine size.

1. GSA will provide a total number of fixtures and types to be served by the new mixing valve. See attached list.

b. Contractor is responsible for programming the new domestic hot water mixing valve and setting the leaving temperature as specified by GSA.

2) New mixing valve assembly will have the following capability

a. Handle high and low demands at a maximum pressure drop of not more than 10 PSI.

b. New valve assembly to have entering hot water, cold water and leaving water Temperature sensors

c. New valve assembly to have entering and leaving Pressure sensors

d. New valve assembly to have thermal disinfection cycle capability.

e. New valve assembly to have recirculating pump, controlled by new valve controller

f. New valve assembly to have BACnet capability

3) New valve assembly piping must be Type L copper with lead free solder joints. Press fitting systems may be used between ½" to 2" where approved by code and with proper approvals and certifications but must not be used in concealed locations.

4) Provide shutoff valves to isolate the entire assembly and drains to allow for repair. Provide a means of bypass of the new domestic hot water mixing valve from water heaters to system piping.

i. Valves must be lead free and have lead free solder joints. Press fitting systems may be used between ½" to 2" where approved by code and with proper approvals and certifications but must not be used in concealed locations.

5) Insulate all piping unless otherwise specified by the manufacturer.

i. Insulation shall be 1” thick fiberglass pipe insulation on pipes up to 2” and 1.5” thick on pipes larger than 2”.

6) Building Automation System Requirements.

a. Points to be added to the BAS graphics entering hot water, cold water, and leaving water temperatures, entering and leaving pressure, recirculating pump status.

b. Tie new points to existing BAS network and program, provide graphics showing new points, provide histories on all new points and provide out of range alarm on the leaving hot water temperature point (adjustable limit) and pump status alarm. Link all alarms to existing critical email alarm.

i. BAS will not control unit, it will be used for monitoring purposes only

ii. Follow GSA Division 25 Spec, object naming template, Data Normalization standard for point naming, and

Niagara graphical standard.

7) Any water service interruptions will need to take place outside of normal hours of operation for the Building.

8) Contractor to field verify all site conditions.
