RFI Title: PTAG – USPTO seeking an engineering assessment of Piller UPS system in Alexandria, VA.

Requirement Title:

Engineering Assessment for Evaluation and Potential Replacement of Piller UPS Systems

Location:

United States Patent and Trademark Office (USPTO) 600 Dulany Street Alexandria, Virginia 22314

Background

The United States Patent and Trademark Office (USPTO) operate mission-critical data center facilities that require continuous, reliable, and conditioned electrical power to support core operations.

The facility currently utilizes Piller UPS (Uninterruptible Power Supply) systems, including Diesel Rotary UPS (DRUPS) configurations with flywheel energy storage and generator integration.

Given the USPTO’s high-availability requirements and compliance obligations under NFPA 70E, IEEE standards, and federal data center reliability objectives, the USPTO seeks a vendor-neutral, independent engineering evaluation to determine whether to continue operating, refurbish, or replace the Piller UPS systems with an alternative solution.

Purpose

The primary objectives of this engagement are to:

1. Assess the current operational condition of all installed Piller UPS systems at the USPTO data center.

2. Identify root causes of any reliability or performance issues.

3. Evaluate lifecycle costs of continued operation versus replacement.

4. Recommend alternative UPS solutions (rotary, static, modular, or hybrid) that meet or exceed USPTO’s load, redundancy, and compliance requirements.

5. Provide a risk assessment for continued use of existing systems.

6. Deliver a comprehensive engineering report with findings, recommendations, and cost-benefit analysis.

Scope

3.1 Data Collection & Documentation Review

• Review USPTO-provided documentation:

o Piller UPS model numbers, technical specifications, and commissioning records.

Form # USPTO-OP-020 (08/2020) Page 2 of 4 o Maintenance logs, service reports, and incident records for the past 3–5 years.

o Load profiles and redundancy configuration diagrams.

• Review facility electrical infrastructure:

o Electrical one-line diagrams.

o Generator integration schematics.

o Cooling and ventilation arrangements for UPS rooms.

3.2 Physical Inspection & Testing

• Conduct on-site inspection of each Piller UPS unit, including:

o Mechanical condition (bearings, couplings, vibration levels).

o Electrical components (capacitors, control boards, power electronics).

o Flywheel/battery condition and charge/discharge performance.

o Harmonic distortion levels and power quality output.

• Perform thermal imaging of electrical components to detect overheating.

• Verify transfer switch operation and response times.

• Inspect integration points with generators and facility electrical distribution.

3.3 Performance & Reliability Analysis

• Analyze historical alarm logs and event records.

• Evaluate Mean Time Between Failures (MTBF) and Mean Time To Repair (MTTR).

• Compare actual performance to manufacturer specifications.

• Identify recurring failure modes and their root causes.

• Assess maintenance frequency, parts availability, and vendor support responsiveness.

3.4 Compliance & Safety Review

• Verify adherence to:

o NFPA 70E – Electrical Safety in the Workplace o IEEE 446 – Recommended Practice for Emergency and Standby Power Systems o OSHA electrical safety requirements

• Evaluate whether existing systems meet USPTO redundancy and uptime requirements.

3.5 Alternatives Evaluation

• Identify and evaluate alternative UPS technologies, including:

o Static double-conversion UPS systems.

o Modular UPS systems for scalability.

o Other hybrid solutions.

• Compare options on:

o Reliability and uptime performance.

o Footprint, cooling requirements, and integration complexity.

o CAPEX and OPEX over a defined lifecycle.

Form # USPTO-OP-020 (08/2020) Page 3 of 4 o Vendor support and parts availability.

3.6 Risk & Cost-Benefit Analysis

• Provide a risk profile for continued operation of current Piller units.

• Develop replacement scenarios with cost estimates, including:

o Full system replacement.

o Phased replacement.

o Major refurbishment.

• Calculate Total Cost of Ownership (TCO) for each scenario.

3.7 Deliverables

The engineering firm will provide to the USPTO:

1. Comprehensive Engineering Report including:

o Current condition assessment.

o Reliability analysis.

o Compliance findings.

o Recommended alternatives.

o Cost-benefit comparison.

o Risk mitigation strategies.

2. Presentation to USPTO Stakeholders summarizing findings and recommendations.

3. Supporting Data Appendices (test results, thermal images, load analysis).

4. Schedule

• Kickoff & Document Review: 1–2 weeks

• On-Site Inspections & Testing: 1 week (subject to USPTO facility access)

• Analysis & Report Drafting: 2–3 weeks

• Final Report & Presentation: 1 week after draft review

5. Qualifications The engineering firm shall:

• Have licensed Professional Engineers (PE) in electrical engineering.

• Demonstrate experience with rotary UPS systems, including Piller DRUPS.

• Be familiar with mission-critical data center power systems.

• Have no financial conflicts of interest with UPS vendors.

6. Acceptance Criteria The engagement will be considered complete when:

• All deliverables are submitted to the USPTO and accepted.

Form # USPTO-OP-020 (08/2020) Page 4 of 4

• The final presentation is delivered to USPTO stakeholders.

• All questions and clarifications are addressed in writing.

• Period of Performance o 90 Days from date of award

• Place of Performance
