Repair and Renovation of Heating, Ventilation, and Air Conditioning (HVAC System Projects Throughout Marine Corps Air Station (MCAS)

The work for this contactor will include, but will not be limited to the demolition, installation, testing/balancing (TAB), complete diagnostics, repair or replacement, preventative maintenance, and emergency response on a variety of specialized cooling systems. The cooling systems can range from a nominal .5 ton to 350 tons of cooling capacity to include, but will not be limited to, both air-cooled chillers and water-cooled chillers, cooling towers, CRAC/CRAH systems for critical server rooms, refrigeration low/medium temperature systems, various sizes of air-handlers, fan coil units, energy management systems (EMS), Direct Digital Controls (DDC), highly complex makeup/exhaust systems, commercial package units, commercial split systems, humidification systems, commissioning/recommissioning of building HVAC systems, Variable Air Volume systems, and other secondary equipment associated with these systems. Secondary equipment examples are Variable Frequency Drives (VFD), pumps, controls, piping, motorized valves, sensors, motors and chemical treatment systems that make these cooling systems complete. The contractor shall also ensure and include with this contract the ability to obtain and mobilize portable chillers that can range between 40 to 300 tons of nominal cooling capacity within an 8 hour response time. Contractor must also ensure that all connections from electrical to various sized chilled piping, fittings, emergency callback service, and VFD pumps will be provided to ensure cooling is reestablished within this 8 hour time period. The work for this contactor will also include, but will not be limited to the demolition, installation, TAB, complete diagnostics, repair or replacement, preventative maintenance, and emergency response on a variety of specialized heating and boiler systems that can range from 1,000,000 BTUs to 5,000,000 BTUs of heating and hot water capacity. These mechanical boiler systems will include, but will not be limited to, natural gas/electric/propane fired boiler systems, fire-tube boilers, water-tube boilers, condensing boilers, electric boilers, domestic hot water boilers, heating hot water boilers, hot water storage tanks with/without coils, heat exchangers, EMS, DDC, and other secondary equipment associated with these systems. Secondary equipment examples are Variable Frequency Drives (VFD), pumps, controls, piping, motorized valves, sensors, motors and chemical treatment systems that make these cooling systems complete.
