APPENDIX D - DWG 114-002 (1).pdf

This document is a comprehensive set of mechanical and electrical design drawings for the repair of the Chilled Water System serving Building 114.

The project involves repair and renovation of the existing chilled water distribution system, including demolition of obsolete equipment and installation of new pumps, piping, and controls. Key mechanical work includes the replacement of eight chilled water pumps with new centrifugal pump units, installation of expansion tank support structures, and complete reconfiguration of the chilled water piping network serving multiple buildings (102, 103, 104, 108, 109, 110). The system includes pressure relief valves, check valves, gate valves, flow control devices, and related HVAC equipment throughout various floors of the facility. The expansion tank and booster water pumps are detailed with specific elevation and support requirements. An HVAC equipment schedule provides detailed specifications for all cooling tower and chiller units, including capacity, electrical requirements, and performance data. The electrical scope encompasses new switchboard and motor control center (MCC) layouts, roof electrical demolition plans, power one-line diagrams, control schematics for the direct digital control (DDC) system, and switch schedules. Electrical demolition notes specify removal of existing equipment and installation of new electrical distribution infrastructure. The control system utilizes a DDC control architecture with chilled water pump controllers, cooling tower controls, and integrated system sequencing. Construction documents include detailed floor plans showing equipment locations, mechanical and architectural details, isometric piping diagrams for each pump, building elevation repairs for rust stain treatment, and a complete set of notes and legends defining all system components and installation requirements.
