Attachment 28 Chiller Plan Upgrade M-1_120508 Model (1).pdf

This document is a mechanical piping schematic diagram for a chiller floor plan (BSMT). The drawing shows a comprehensive layout of the building's mechanical piping systems at basement level, with a scale of 1/4"=1' indicated. The diagram contains detailed annotations and a legend identifying 14 keyed plan notes applicable to the drawing.

The schematic illustrates the routing and configuration of chilled water piping, condenser water piping, relief valves, pump stations, air separator systems, and related mechanical equipment throughout the basement level of the facility. Key elements identified in the notes include ductile iron piping for various applications, high-reinforced concrete housekeeping pads for equipment mounting, relief valve specifications for chilled and condenser water systems, pump positioning requirements, and emergency ventilation duct specifications. The drawing serves as a technical reference for mechanical contractors, engineers, and construction professionals involved in the installation, maintenance, and inspection of the building's chiller and water distribution systems.
