2005_Existing NAL Chiller Drawings.pdf

This is a design document for the replacement of chillers at a U.S. Department of Agriculture Agricultural Research Service facility, dated March 2005, serving as the final submittal for a construction project.

The document contains comprehensive design specifications and architectural/mechanical drawings for the demolition and replacement of existing chiller equipment at a USDA ARS facilities location. The project scope includes partial basement asbestos abatement, partial mechanical basement demolition, partial electrical basement demolition, and replacement of water chillers (designated CH-1 and CH-2). The design provides detailed floor plans, elevation drawings, demolition plans, and mechanical/electrical schematics showing the existing switchgear "MSG" and new motor control center "MCC-CH" specifications rated for 480V, 3Φ, 3W, 600A, 42,000 AC. The water chiller schedule specifies two chiller units with associated compressor, condenser, and auxiliary equipment details. The document includes a sequence of operation for condenser water, chillers, free-cooling systems, and refrigerant monitoring protocols. General demolition notes specify that all work shall be performed in accordance with applicable safety and environmental regulations, with contractor responsibility for proper documentation, asbestos handling per EPA protocols, and coordination with facility operations. The design incorporates standard mechanical symbols, abbreviations, and includes site maps, vicinity maps, equipment schedules, and detailed door and frame specifications for the project implementation.
