Aberdeen Test Center Small Arms Systems Division HVACR M&R Support Performance Work Statement

I. Background

Aberdeen Test Center (ATC) provides various simulated environment testing in support of a diverse test arena for the Department of the Army. Most of these test services rely on the use of complex environmental test chambers that include custom-built Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) systems. These HVACR systems are not fully comparable to other residential and/or industrial HVACR systems, and generally require specialized components, systems and/or a variety of refrigerants to properly function. Further, many of these systems were manufactured over 25 years ago, potentially limiting the availability of technical documentation and/or replacement parts.

These systems are crucial in the testing of weapons, ammunition, body armor and other soldier systems that ultimately impact the Warfighter’s ability to complete his/her mission. Therefore, it is critical that these systems always remain operable, 24 hours per day, 7 days per week, 365 days per year, and fully comply with the strict testing standards set forth by the Department of Defense (MIL-STD-810G: Environmental Engineering Considerations and Laboratory Tests).

II. Scope of Work

The Contractor will be tasked with maintenance and repair for all HVACR and ancillary (e.g. associated electronics, electrical components, controls, etc.) equipment. Work efforts will be concentrated at the Michaelsville Range Complex (MRC) on Aberdeen Proving Ground, MD and include but are not limited to the following:

Signature Range – Closed Range 4 Indoor Firing Gallery – Position 16/17 Sand and Dust Chamber and Rain Chamber – Position 18/19 Extreme Temperature Chamber (ETC) -Position 19A, Small Arms Environmental Chamber (SAEC) – Position 19B

The MRC consists of 12 small and medium caliber firing positions in total. Each position is an Army laboratory facility where air supply, negative-pressure differentials, temperature and humidity are controlled and managed by HVACR equipment. The Contractor, however, may be tasked to perform service on additional ATC HVACR assets as requested by the ATC Contracting Officer Representative (COR).

The following outlines service requirements for the three elements of this M&R contract: 1) Scheduled Maintenance, 2) Unscheduled Maintenance and 3) Replacement Parts.

1) Scheduled Maintenance

The Contractor shall provide 128 hours of technician (journeymen-level) labor towards scheduled maintenance efforts. For initial cost estimating purposes the contractor shall assume that 104 hours are at standard labor rate and that 24 hours are to be at a premium hour rates. These hours will be utilized at the discretion of the ATC COR to support tasks listed below. The ATC COR will coordinate scheduled maintenance efforts through a designated Contractor representative. At the completion of each service visit, a service ticket shall be provided to the ATC COR detailing personnel on site, nature of the service, duration of visit, status of relevant equipment, any replacement parts utilized, and any other information relevant to the service performed.

ATC has identified the following maintenance tasks to be completed as scheduled maintenance. Note that this list is NOT all inclusive and other tasks reasonably considered basic or routine may be requested by the ATC COR as scheduled maintenance.

1. Perform system safety checks on all equipment

2. Perform visual inspection on all mechanical, electrical, refrigeration components to identify any areas of degradation; recommend repair/replacement of any components as necessary

3. Perform refrigerant leak checks on all relevant equipment

4. Perform system calibration on equipment where necessary (e.g. back pressure regulators, thermal expansion valves, etc.)

5. Perform line-to-ground continuity testing to verify appropriate electrical connections/components are grounded

6. Verify, record, and submit appropriate mechanical readings of all equipment (e.g. pressure, temperature, humidity)

7. Verify, record, and submit appropriate electrical readings (e.g. voltage/current readings on following points: compressor line, fan motor line, main disconnect, dehumidifier units, electrical heater)

8. Inspect, service, replace as needed following mechanical components (not exhaustive list): compressor, compressor oil level, accumulator, liquid line receiver, liquid line sight glass, belt drives and pulleys (grease as needed), air filters (note that some consumed filters may contain lead or other hazardous materials), filter driers, refrigerant metering device, hot gas by-pass valves, condenser and evaporator coils (requires non-corrosive and bio-degradable agent to be rinsed thoroughly with pressurized water), chamber door gaskets, Armstrong humidification units, dehumidification units, rooftop exhaust fans/package units

9. Inspect, service, replace as needed following electrical components (not exhaustive list): magnetic contactors, switching relays, current relays, solenoid coils, pressure switch, capacitors, Silicon-Controlled Rectifier, terminal blocks, printed circuit boards, compressor, blower motor, fan motor

10. Perform software maintenance and provide on-going support for all related software; service may be required up to five (5) times per year

11. For negative-pressure ranges (e.g. CR4), perform air balance testing to ensure proper pressure readings/ventilation; service may be required up to three (3) times per year

12. The Contractor is responsible for recommending additional preventative maintenance for MRC equipment based on manufacturer recommendations and/or other industry standards.

13. Additional tasks that are generally and reasonably considered routine and/or reoccurring may be assigned by the ATC COR. An example of a reoccurring task would be replacing equipment requiring frequent replacement due to a heavy workload, electrical imbalances, etc.

2) Unscheduled Maintenance

For emergency services, efforts exceeding the time capacity of scheduled maintenance as defined above and/or efforts outside of the scope of scheduled maintenance as defined above, the Contractor shall provide necessary M&R support under the following guidelines:

1. The ATC COR may request unscheduled maintenance to complete emergency repair service to support an upcoming or active test event. Following an emergency repair request, the Contractor is required to respond on-site, prepared to work within 24 hours of initial request. Emergency repairs shall be completed within 72 hours to allow for continued testing. If a repair cannot be completed within 72 hour timeframe, the Contractor shall document the problem, estimate timeframe for repair completion, and notify the ATC COR. The Contractor must be available at all times, 24/7/365 (including holidays) in order to support around-the-clock testing.

2. Non-emergency maintenance or repair requests shall be completed within five (5) business days.

3. For an unscheduled maintenance request, the Contractor shall troubleshoot the observed failure/deficiency as directed by the ATC COR. Prior to taking any corrective actions or procuring any replacement parts, the Contractor shall coordinate with the ATC COR to report any findings, identify any repair cost and determine a plan of action.

4. Additional tasks within the general scope of work may be requested to support ATC HVACR equipment other than those pieces listed in Appendix A.
