STATEMENT OF WORK

REPAIR HVAC B1510

08.26.2025 Project: VLSB 20-0008

SCOPE OF WORK:

This Statement of Work (SOW) is for the design, demolition, and installation of HVAC equipment at building 1510. The building is 4,400 square feet and conditioned with a 4-pipe system composed of a one year old chiller, 40 year old air handling unit with straight ducted air, and a 9 year old boiler system supply hot water coils. The air handling unit, hot water coils, and boiler will be the main components replaced.

DEMO:

• The contractor shall demolish the existing air handler unit and any associated isolation valves.

• The contractor shall demolish all hot water coils and any isolation valves located near the coil.

• The contractor shall demolish all ductwork in the mechanical room.

• The contractor shall demolish the existing boiler, associated components, and any isolation valves. The boiler shall be returned to the government.

• The contractor shall demolish the existing domestic water heater, associated components, and any isolation valves.

• The contractor shall demolish the existing controls.

NEW WORK:

The contractor shall design and install the following new components based on the existing chiller:

• 25 ton air handling unit (AHU) that utilizes existing electrical infrastructure.

• Hot water coils in the location of the demolished ones. Hot water coils shall be sized appropriately for the areas they are serving.

• Isolation valves on the supplies and returns of all hot water coils and the AHU.

• Air separator with basket strainer on the inlet side of the chiller pump.

• Buffer tank on chilled water loop.

• Gas fired boiler and accessories to support HVAC system.

• Gas fired water heater and accessories for domestic hot water.

• Isolation valves on the supplies and returns on the HVAC boiler and domestic boiler.
