3. PHASING & CONSTRUCTION REQUIREMENTS:

For this project, any required utility system outages needed in order to perform work will be scheduled at the convenience of the VA and may require work to be performed during hours where government staffing is available. This may be either during business hours or after-hours work, depending on the nature of the outage and VA staffing availability. All utility outages will be coordinated two weeks in advance with the project COR.

To complete the design and construction of the cooling tower and flow meter, the facility will transfer the primary cooling tower system load to the secondary cooling system. The contractor must ensure the outside air temperature is below 80 degrees Fahrenheit before starting this task; otherwise the cooling tower will not support the system demand. The work needed for the flow meter and Cooling Tower #1 will be completed simultaneously.

To complete the design and construction of the facility fresh air supply and main exhaust, AHU-3N, and AHU-2AE101, some work will be conducted 4:30pm-6:30am, Mon-Fri, or on Sat and Sun, excluding federal holidays, unless otherwise coordinated with the COR.

To complete the design and construction of chilled water pumps and water distribution pumps, the contractor will coordinate work with the VA COR.
