PERFORMANCE WORK STATEMENT (PWS)

VLF TESTING OF MEDIUM VOLTAGE POWER LINES

911th Airlift Wing, Coraopolis, PA 15108

1.0 DESCRIPTION OF SERVICES

1.1 Objective

The intent of this requirement is to conduct VLF (Very Low Frequency) testing on seventy-four (74) medium voltage power lines. This is a preventive maintenance inspection requirement to record and report the operating integrity of the system.

1.2 Scope of Work

The Contractor shall provide all labor, supervision, equipment, tools, instrumentation, materials, travel, and incidental items necessary to inspect, test, and document the conditions of the identified power lines.

1.3 Applicable Standards

All references to government and industry standards must be based on the current versions at the time of the solicitation. All work shall be in accordance with:

1. DoD Unified Facility Criteria (UFC) via the Whole Building Design Guide (http://www.wbdg.org)

2. Air Force Engineering Technical Letters (https://www.e-publishing.af.mil)

3. Applicable Industry Standards (ANSI, IEEE, NETA, OSHA)

4. State and Federal OSHA regulations (specifically OSHA 29 CFR 1910.269 for Electrical Safety and 29 CFR 1910.146 for Confined Spaces)

5. National Fire Protection Association (NFPA-70, NFPA-70B)

6. Institute of Electrical and Electronics Engineers (IEEE 400.2, IEEE 400-2012)

7. International Electrical Testing Association (NETA) standards for maintenance testing

2.0 SPECIFIC REQUIREMENTS & VLF TESTING

2.1 General Testing Plan

The Contractor shall develop and execute a comprehensive VLF testing plan that ensures the integrity and reliability of the medium voltage power lines.

1. Power Interruption Impact Analysis (PIIA): The Contractor shall conduct a PIIA for each affected facility to determine optimal, low-impact testing and outage windows.

2. Government Approval: The complete testing plan must be submitted for Government approval. No physical work may proceed until the Government has approved the testing schedule.

3. Plan Minimum Contents: At a minimum, the testing plan shall include:

* Project description and testing objectives.

* Testing procedures and specific testing equipment/calibration data.

* Detailed timeline of power outages, clearly identifying which building or area will experience an outage.

* Anticipated issues or hazards the Contractor may experience during execution.

* Information should be submitted to the Safety Officer if contractor needs access to any confined space or the use of heavy equipment.

2.2 Pre-Testing Activities

1. Site Survey: Assess the accessibility of the power lines, manholes, and overhead lines, and identify potential safety hazards.

2. LOTO Procedures: Implement strict Lockout/Tagout (LOTO) procedures to ensure the test circuits are completely de-energized, isolated, and safe.

3. Calibration: Calibrate all testing equipment according to manufacturer specifications and maintain active certification logs.

2.3 Testing Execution

1. Coordination: Coordinate closely with Base Engineering prior to any energization or de-energization.

2. Voltage Application: Apply the specified VLF voltage to the power lines for the specified duration, gradually increasing the voltage to the test level.

3. Monitoring: Continuously monitor leakage current at regular intervals. Observe for signs of insulation breakdown.

4. Action Upon Failure: In the event of an insulation failure, the Contractor shall immediately reduce the voltage to zero, secure the segment, and notify the COR. The Contractor is NOT authorized to conduct repairs under this contract.

2.4 Post-Testing Activities

1. Discharge: Ensure cables are safely discharged using a grounding discharge rod for a minimum of 5 minutes post-test.

2. Restoration: Safely restore the tested lines to their normal operating configuration.

3.0 DELIVERABLES AND REPORTING

3.1 Final Test Report

Within fifteen (15) calendar days of testing completion, the Contractor shall prepare and submit a comprehensive report in a digital spreadsheet format including:

1. Project description, objectives, and test dates.

2. Specific equipment used and associated calibration certificates.

3. Complete test results detailing: Circuit ID, Test Voltage, Test Duration, Leakage Current Readings (at 1-minute intervals), and a definitive Pass/Fail determination for each segment.

4. Time-stamped photographs or videos of any defects, physical deterioration, or anomalies observed during testing.

5. Location data identifying failed segments requiring future repair.

4.0 SPECIAL CONTRACT REQUIREMENTS

4.1 Contractor Qualifications

Contractor personnel conducting this testing are preferred to be NETA certified. If the Contractor utilizes non-NETA certified technicians, they must submit a comprehensive qualification packet demonstrating equivalent technical capability and medium-voltage testing experience to the Contracting Officer for approval prior to award.

4.2 Base Access & Security

1. Vetting Requirements: All contractor personnel requiring base access must be Real ID compliant. Vetting requests must be submitted to the Contracting Office at least five (5) business days prior to the desired access date. This will include all names, social security numbers, birth dates, drivers license numbers and state of issue.

2. Vehicle Inspections: All commercial vehicles must enter through the designated Commercial Vehicle Inspection gate.

5.0 HOURS OF OPERATION:

Hours of Operation: The normal hours of operation are 7:00AM to 4:00PM, Monday through Friday. However, this project could be subject to work outside of normal hours if approved by the government.

Recognized Holidays: no testing will be done on these days Labor Day – September 7, 2026 Columbus Day – October 12, 2026 Veteran’s Day – November 11, 2026 Thanksgiving Day – November 26, 2026 Christmas Day - December 25. 2026 New Year’s Day – January 1, 2027 Martin Luther King Day – January 18, 2027 Washington’s Birthday – February 15,2027 Memorial Day – May 31, 2027 Juneteenth – June 18,2027 Independence Day – Observed Monday, July 5, 2027
