Statement of Work Uninterruptible Power Supply (UPS) Unit Maintenance

BACKGROUND

Under Chairman of the Joint Chiefs of Staff Instruction (CJCSI) 6130.01, the U. S. Naval Observatory (USNO) is directed to supply the Master Clock (MC) for the DoD at a level that meets or exceeds mission requirements. The U.

S. Naval Observatory (USNO) serves as the official source of time for the U. S. Department of Defense and a standard of time derived from the USNO Master Clock for the entire United States. Network Time Protocol (NTP) servers, web-based time synchronization, GPS timing products and services, Two-Way Satellite Time Transfer, and Astrometry / Geodetic calculations originate at the U.S. Naval Observatory. USNO is seeking qualified Eaton UPS provider maintenance for 4 very large Eaton Uninterruptible Power Supply (UPS) units that provide backup power at the USNO.

SCOPE

Consistent power during all possible external forcing functions is vital to keeping the clocks, measurement systems, and management computers operational. The UPS units have internal computers that control the system and provide telemetry and alarm information to Master Clock automatic monitoring systems. Maintenance on the aging UPS units will be completed by a qualified Eaton UPS provider, and includes providing regular preventive maintenance two (2) times per year per unit; rapid break/fix response; two (2) full battery replacements over the course of the contract; and two (2) full capacitor replacements over the course of the contract, with battery and capacitor replacements frequency determined by the Eaton manufacturer’s specifications, or by the state of the existing batteries and capacitors.

REQUIREMENTS:

The USNO requires individual line items for each of the items below, to be executed as needed.

1. Qualified Eaton UPS Maintenance Provider. Parts noted below must be Original Equipment Manufacturer (OEM) components or alternates approved by the Technical Point of Contacts (TPOCs) listed below.

2. Equipment covered by the Preventive Maintenance includes the following four UPS units.

a. Serial #EQ211ZBA02; Model #9315-100-160 (EOSL)*

b. Serial #EQ201ZBA03; Model #9315-100-160 (EOSL)*

c. Serial #EY194CAA06; Model #9390-100-120 (EOSL on January 1, 2027)

d. Serial #ED492CAB08; Model #9390-40-80 (EOSL on January 1, 2027)

Note that the 9315 model is End of Service Life (EOSL) and not supported by Eaton.

3. Provide biannual preventive maintenance to include at a minimum:

• At least 2 on-site visits per contract year to perform sealed battery preventive maintenance and on-site inspection as specified by the Eaton manufacturer.

4. Quote an hourly rate for quick response break/fix service. When possible, break/fix services will be quoted separately and may be handled under a Government Purchase Card (GPC) provided they fall under the micro purchase threshold.

• On-Site response time within 4 hours, including 24x7 after hours support.

5. Include 2 options for full battery replacements throughout the term of the contract, including all delivery and disposal costs and warranties. Replacement parts must be Original Equipment Manufacturer (OEM) components or alternates approved by the Technical Point of Contacts (TPOCs):

• Model #9315-100-160. OEM Battery Part # PWHR12540W4FR, VRLA Sealed, 80 jars.

• Model #9315-100-160. OEM Battery Part # PWHR12540W4FR, VRLA Sealed, 80 jars.

• Model #9390-100-120. OEM Battery Part #PWHR12120W3FR, VRLA Sealed, 40 jars.

• Model #9390-40-80. OEM Battery Part #PWHR12200W4FR, VRLA Sealed, 40 jars.

6. Include 2 options for full capacitor replacement throughout the term of the contract, including all delivery and disposal costs and warranties. Replacement parts must be OEM components or alternates approved by the TPOCs:

• Capacitor Upgrade for Serial #EQ211ZBA02; Model #9315-100-160. Includes qty 1 9315-100- 160 AC Oil Filled Capacitor Upgrade and qty 1 DC Electrolytic Capacitor.

• Capacitor Upgrade for Serial # EQ201ZBA03; Model #9315-100-160. Includes qty 1 9315-100- 160 AC Oil Filled Capacitor Upgrade and qty 1 DC Electrolytic Capacitor.

• Capacitor Upgrade for Serial #EY194CAA06; Model #9390-100-120. Includes qty 1: 9390-100- 120 400/480V AC and DC Oil Filled Capacitor.

• Capacitor Upgrade for Serial #ED492CAB08; Model #9390-40-80. Includes qty 1: 9390-40-80 400/480V AC and DC Oil Filled Capacitor.

UPS Capacitors must be replaced with OEM or approved components so as not to risk damage and/or loss of mission. The new components must fit a custom size and have performance requirements that may make them as not readily available as an off-the-shelf item.

As noted above, the units are EOSL and parts may be difficult to source. Interested vendors will need to demonstrate their ability to obtain parts and understand market costs, as this contract is being issued on a Firm-Fixed Price basis.

7. Provide an hourly rate for the cost of additional uncovered break/fix repairs when necessary, to include any discounts available under the support plan. Such repairs may be handled under the micropurchase threshold and separately from this contract where possible.

FACILITIES, EQUIPMENT, AND TRAVEL:

Completion of these tasks will be performed at USNO DC. Pricing should include the cost of on-site service.

REPORTS TO USNO:

Contractor shall provide service maintenance reports to the USNO Technical Point of Contact (POC) listed below.

This report shall include progress made for each preventive maintenance visit, a summary of any problems or areas of concern for which government assistance or guidance is desired, a description of work planned for the following month, and a statement of any anticipated deviation in the contractor’s planned effort to achieve contract objectives.

Dissemination control of output products such as documents: The output products of the study shall be considered “DISTRIBUTION D: DOD AND DOD CONTRACTORS ONLY,” and shall not be further disseminated without written permission of USNO. Contractor shall comply with all relevant USNO, Navy, DoD dissemination, security and information assurance rules.

Acceptance and Quality Assurance The contractor shall present final report(s) to the USNO technical lead for acceptance. The USNO technical lead shall address any issues that may arise during the execution of this contract.

PERIOD OF PERFORMANCE:

The period of performance is 12 months from the date of award, with 4 option periods available as anticipated below:

An option to extend for the continuance of services may be provided upon completion of the base period. The scope of work to be completed during the option period is dependent on the current status of the project at the end of the base period, however, as the schedule for completion of the project is a collaborative effort with the Government.

Pursuant to FAR clause 52.232-18, funds are not presently available for this contract. The Government's obligation under this contract is contingent upon the availability of appropriated funds from which payment for contract purposes can be made. No legal liability on the part of the Government for any payment may arise until funds are made available to the Contracting Officer for this contract.
