This is a control drawing document for an expanded rehab medicine and rehabilitation facility project at NAVAICS Prescott, Arizona. The document contains architectural and mechanical systems drawings with detailed specifications for building controls and monitoring systems.

The primary focus is on three key mechanical systems: (1) Elevator Sump Pump Monitoring, which requires the CHW (Chilled Water) support to monitor pump status and generate alarms for high water levels; (2) Chilled Water (CHW) System Controls, which specifies an air-cooled chiller with factory-provided controls, a CHW pump with variable frequency drive, and user-adjustable setpoints for supply water temperature (typically 44-48°F) and differential pressure monitoring; and (3) Campus CHW Metering (Alt. 1), which measures CHW consumption across multiple buildings. The document indicates that all alarms should differentiate individually between buildings, and the CHW system shall be capable of determining differential pressure on existing system pumps. A CHW System Control Diagram (Base Bid) is provided showing the piping schematic, control points, and system interconnections. The drawing is prepared by GLHN Architects and Engineers for the Office of Construction and Facilities Management, dated 15 October 2012, with project number 148-MI603 and reference 649-409.
