Generator & Automatic Transfer Switch (ATS) Upgrade

Dated 24 Aug 16

1.0 BACKGROUND:

The National Institute of Standards and Technology (NIST) maintains the standards for time and frequency for most users in the United States. NIST provides a variety of services designed to deliver time and frequency signals to the people who need them. The signals are broadcast via several mediums, including high and low frequency radio, the Internet, and telephone lines. These signals are used to synchronize millions of clocks every day, throughout the United States and around the world.

2.0 PURPOSE:

NIST Time and Frequency Radio Station WWV requires a new Emergency back-up generator and automatic transfer switch. The current generator and transfer switch has become unreliable. In case of loss of commercial power, the new units will supply standby power to the building. Our group depends on the standby emergency power to fulfill our mission. Equipment must be able to tolerate the unique pulsating load imposed by the WWV transmitters.

3.0 STATEMENT OF WORK (SOW)

3.1 GENERAL:

3.1.1 Other than ordering and delivering equipment & supplies no work may begin on the site until January 3rd 2017.

3.1.2 All work must be completed and inspected for operational reliability before March 17th

2017.

3.1.3 Equipment installation will require connections to the building electrical distribution equipment. This equipment may be de-energized for no more than 16 hours total, consisting of two consecutive days of 8 hour periods during normal working hours. Power must be restored in between these outages. The power outages must be coordinated with the COR no less than 14 days prior to the proposed outage. Any additional coordination with outside utility companies is the sole responsibility of the contractor.

3.1.4 A kick-off meeting will be required for contractor principles within 30 days of award.

3.1.5 An equipment removal & installation plan must be presented at the kick-off meeting for approval before work may proceed.

3.1.6 A safety plan including a Job Hazard Assessment (JHA) must be presented at the kick-off meeting for approval before work may proceed.

3.1.7 Any equipment, materials, or debris removed from the site in reference to the SOW will be disposed of by the contractor in accordance with federal and local disposal regulations.

3.1.7.1 All equipment removed and installed will need to fit through an 8’ tall & 9’ wide garage door

3.1.8 Any visits to the site must be coordinated with the COR and Radio Station staff. Deliveries will be made to 5701 N HWY 1 Fort Collins Colorado, 80524

3.1.9 All materials necessary to complete the project will be on-site on or before January 3rd 2017.

3.1.10 Two copies of all maintenance and operational manuals will be provided for each piece of purchased equipment and shall be provided to the COR.
