This work will be performed on a medical center campus requiring minimal, coordinated power outages carried out at times that minimize the impact to patient care services. The proposed schedule shall be reviewed by the VAMC Engineering Service; any requirements for adjusting the schedule (e.g. to minimize disruption to the VAMC) shall be incorporated by the Contractor.
Contractors shall report deficiencies that are deemed critical or catastrophic immediately to the Contracting Officer and Chief of Engineering Service for immediate action.
Work items, definitions, and references shall comply with the latest edition of the NETA Maintenance Testing Specifications (MTS 2015) and with the VHA Directive, Electrical Power Distribution System (included document as 1028_D2014_07_25). Below is an example list of equipment that must be maintained and tested; additional equipment may be necessary:
Switchgear and Switchboard Assemblies.
Transformers, Liquid-Filled.
Switches, Air, No load break
Circuit Breakers, Air, Insulated-Case/ Molded-Case.
Circuit Breakers, Air, Low-Voltage Power.

Work to be in compliance with NETA Maintenance Testing Specifications (MTS 2015) standards and typical medical center breaker testing work. Electrical equipment (including, but not limited to switchgears, switchboards, distribution panels, motor control centers, and all related components) is inspected, tested, maintained, and/or calibrated every 36 months, and all work must be documented. Typical examples of the work necessary to comply with NETA and VA requirements follow; there may be additional requirements that apply:
(a) Use lint-free rags to clean conductors, contact points between the circuit breakers and main buss bars, buss bars and interior of the electrical equipment. Use a vacuum cleaner to remove large debris; compressed air is not to be used for this purpose. Visually inspect for signs of overheating, misaligned contacts, damaged insulation, or lose lugs.
(b) Lubricate all moving parts with manufacturer s approved lubricants.
(c)Test and exercise circuit breakers located in switchgears, switchboard, and distribution panels to ensure operation under overload, and short circuit conditions.
(d) Test ground fault protection devices for proper function if they are installed in the Electrical Power Distribution System.
(e) Inspect and tighten ground connections. Test ground resistance for the entire facility grounding system.
(f) Identify the hot spots in the electrical equipment by using infra-red thermal detecting equipment. Tighten problem connections to meet equipment manufacturers specification using a torque wrench or other approved devices.
(g) Calibrate and maintain adjustable protective relays.
(h) Test all control systems equipment for proper operation after maintenance is performed and before placing them back in normal service.
(i) To ensure access is limited to qualified persons, electrical equipment is to be secured. For example, electrical panels located in corridors or other public areas are to be locked or otherwise secured.
This is a sample of a Schedule and Inventory of Electrical Power Distribution System equipment to be maintained, inspected, and tested under this Scope of Work and in accordance with NETA Maintenance Testing Specifications (MTS 2015). The schedule will be formalized through discussions and agreement with the COR and the VA Medical Center.

Special Considerations by the Contractor
All sampling, testing and inspection shall be done in accordance to all NEC, NETA Maintenance Testing Specifications (MTS 2015) and NFPA Codes and use of industry standard methods for the subject described work herein. The contractors shall have and provide all necessary tools, equipment, and Personal Protective Equipment (PPE) to perform the work herein safely, effectively and timely. Tools, equipment, and PPE shall comply with the requirements of OSHA Standard 29 CFR 1910, Subpart I, and NFPA 70E. Prior to initiating work, Contractor shall provide documentation that all instruments, test equipment, tools and PPE have current calibration. Dated calibration labels shall be visible on all instruments, test equipment, tools and PPE as appropriate.
The contractor will be responsible for the cleanliness of the building area both interior and exterior to associated buildings.
The contractor s workmen shall provide and utilize all safety requirements in accordance with all applicable NFPA and OSHA regulations. As a required example of work, provide PPE and training certification to rack in/out breakers. Refer to Section 2. Qualification for Contractors for additional requirements.
Contractor s workmen are subject to rules and practices, which comply with national and local safety codes. All maintenance and testing shall be done on equipment de-energized from the AC source as possible. Where temporary feed for power is required to keep vital circuits in operation, provisions shall be made to isolate these circuits from the equipment being serviced. Circuits that will require being de-energized prior to work will require a Utility Shutdown that must be coordinated with the project COR or designated representative before start of work. Prior to any testing all circuit conductors shall be checked to determine that the temporary leads are not feeding back into equipment being serviced.
Contractor shall notify the COR two weeks in advance of the proposed date of starting work in each specific area of campus. Arrange such dates to ensure accomplishments of this work in successive phases mutually agreeable to the Medical Center Director, COR and Contractor.
The contractor will not be allowed to use Government tools, materials, PPE and/or labor for this effort.
Warranty:
a. Shall include all labor and materials for repairs or adjustments arising from workmanship related issues and/or contractor supplied parts and materials for a period one year from completion of contract.
b. Warranty shall include the following:
1. Summary of maintenance procedures required to maintain the warranty.
Organizations, names and phone numbers of persons to call for warranty service.
Response time for warranty calls shall be 90 minutes or less.
The personnel responding to any warranty call shall be knowledgeable and capable (as specified in this SOW and referenced codes and requirements) of troubleshooting, adjusting, and when possible, repairing the equipment covered under this contract.
END.
