This document is a comprehensive set of engineering drawings and specifications for HVAC system replacement at Tinker Air Force Base (TAFB), Building 1. The project involves replacing the air conditioning system and includes detailed mechanical, control, and electrical design documentation prepared by Johnson Controls, Inc.

The scope encompasses replacement of power distribution, lighting, and air conditioning systems for Building 1 at Tinker AFB in Oklahoma City, Oklahoma. Key systems included are the chilled water/heating hot water system, air handling units (AHUs), control air systems with damper and valve schedules, and associated mechanical equipment such as pumps and starters. The documentation provides detailed bill of materials, piping diagrams, wiring schematics, equipment specifications, and operational sequences for multiple AHUs (Units 1, 3, 4, 5, 6, 7, and 8) with associated booster coils and controls. Control sequences address temperature and humidity management, water valve operations, damper positioning, and safety shutdowns. The drawings include valve and damper schedules with specific actuator information, electrical starter details for CHW and HHW pumps, and local control panel configurations. The project also specifies chilled and hot water system operations, including provisions for seasonal switchover and automatic control logic to maintain building comfort conditions while managing energy consumption.
