Summary: HVAC Systems Replacement Design and Construction Documentation

This document set comprises architectural and engineering drawings for the replacement of HVAC systems in Building 298 at Marine Corps Air Station Cherry Point, North Carolina (Project FM0011). The package includes comprehensive mechanical, electrical, and structural drawings detailing demolition work, new equipment installation, control systems, and related infrastructure modifications across multiple building areas including the library, equipment room, mechanical closet, rapids office, and omega travel office.

The scope encompasses removal of existing HVAC units, ductwork, piping, and controls, followed by installation of new modular air handling units (AHU-1 through AHU-4), condensing units (CU-1 through CU-3), steam unit heaters, supply and return ductwork with insulation, control panels with digital thermostats and sensors, electrical connections, and structural supports. The work includes asbestos/lead testing and abatement procedures per specification section 02581, fire damper installation in wall penetrations, refrigerant line routing through the building, steam supply and condensate return piping, and VAV box controls. Equipment schedules specify air conditioning units ranging from 5,717 to 8,900 CFM capacity, fan specifications with various horsepower ratings, and condensing unit models with differing capacities. The documentation indicates multiple additive bid items (0001 and 0002) addressing additional work in specific areas such as the rapids office and omega travel office, with detailed demolition notes, drawing notes, and control sequence specifications throughout the plan sets. Control system design includes three independent control zones with thermostats, humidity sensors, and modulating dampers to manage space temperatures and condensation.
