DIVISION 1 GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: Lincoln Boyhood National Memorial is located in Lincoln City, IN. The National Park Service began operation of the location in the early 1960’s. The structures affiliated with this project remain intact and accessible. The HVAC systems within the structures will be replaced entirely with the exception of the existing, original heating/cooling duct systems.

1.2 Work Covered by the Contract Documents: see Division 23 Sections 235416.13, 238126, 238123

A. Project Location:

Lincoln Boyhood National Memorial 3027 E South Street Lincoln City, IN 47552

B. Work consists of: The project will consist of replacing 6 HVAC systems at the following locations: Quarters 2

Housing (Q-2), Quarters 4 Housing (Q-4), Maintenance Staff Office (MX), Administration Building (ADM), Curatorial Office Complex (CUR).

1. Unless specifically noted, all HVAC systems will be from the same manufacturer and whenever possible, the same model number. The installation and operation of all HVAC systems will be alike for ease of preventative, recurring, and corrective maintenance operations. Common accessories such as thermostats, air filters, and piping will be of the same manufacturer and model whenever possible. The contractor may offer different brands of heating and cooling units, but each component must be the same brand, i.e., furnaces will be the same manufacturer, cooling units will be the same manufacturer.

EXCEPTIONS: the “mini-split” heat pump unit to be installed in the Curatorial Office location need not be the same brand as the other locations. The mini-split unit will be of comparable quality to the existing unit and provide comparable AFUE (AFUE 96-98) and SEER (17 minimum) numbers as to all units. The ceiling mounted HVAC unit in the Curatorial Artifact Storage room will be comparable to the current model (Liebert) installed in the room. The unit must have automatic humidity and climate control features unique for the storage of historical artifacts. In addition to the climate control features, the unit must be ceiling mounted as floor space within the room is not available.

2. All current vent and duct systems will be utilized. Current wall or roof penetrations will be reutilized if possible. All Plenums and flexible duct connections will be replaced with new.

All cooling coil units to be replaced. All vent and duct systems will be professionally cleaned before installing new HVAC units. All units will have condensate filters installed in the condensate drain systems to remove toxic impurities entering into the sanitary sewer system or ground. Contractor will be responsible for all utility hook-ups (gas, electric, plumbing).
