Attachment 6_Bldg. 5000 Mechanical HVAC Floor Plans_2nd Floor.pdf

This document is a Mechanical HVAC System Plan for a building's second floor, depicted as an architectural floor plan with detailed ductwork and equipment layouts.

The plan illustrates the heating, ventilation, and air conditioning distribution system throughout the second floor, with color-coded elements indicating different system components: blue lines represent supply air and ductwork for factory-supplied diffusers; orange lines show exhaust air and return air pathways; and various symbols denote specific HVAC equipment and grilles. The keyed notes provide technical specifications for connection details, including instructions for connecting ductwork to supply air diffusers, specifications for factory-supplied diffuser plenums, supply air grille sizing and neck dimensions, return air grille types with balance requirements, combined size specifications for exhaust plenums, ductwork sizing from below, and air vent locations. The legend identifies multiple system components including air-handling units and CDUs (condensing units), supply air systems, heat pump air for fossil fuels, supply air and duct temperature management, other supply and return air components, exhaust air systems, and variable air volume controls. The plan is drawn to scale at 3/16" = 1'-0" and references Sheet 1 of 3, indicating this is part of a larger set of mechanical design documents for the building.
