W-201-1.jpg

This is a technical schematic drawing showing the hot water system design for a control system replacement project at Peterson Air Force Base in Colorado Springs, Colorado. The drawing (W-201-1) depicts a hot water system layout with three boilers (LS-208, LS-209, LS-210), multiple temperature transmitters (TT), flow transmitters (FT), and associated piping and controls.

The drawing includes a bill of materials listing components such as differential pressure transmitters, flow sensors, and level switches. The sequence of operations section details how the heating water system functions, including temperature control parameters (180°F at 10°F outside air, 120°F at 75°F outside air) and the control logic for the main water supply differential pressure and lead/lag pump operation through the building automation system (EMCS). This appears to be part of the technical documentation for the Building 1 Control Conversion project being explored in the Air Force Space Command's sources sought notice.
