The TRS facility located at 1000 Red River, Austin, Texas 78701 is two multiple story buildings with a linking level connecting the east and west towers. The base bid for TRS HVAC Components Retrofit consists of a complete renovation of the hot and chilled water central plant on the fifth floor of the west building. This work includes replacement of all pumps, two water cooled chillers, two air cooled chillers, two boilers and controls upgrades from pneumatic to Direct Digital Control (DDC). Existing controls are a hybrid DDC and pneumatic system. The cooling towers will remain, with minimal work required. Miscellaneous work shall include multiple return air fan replacements, motor replacements and VFD installations, controls sequencing and instrumentation upgrades, and new piping arrangements. The central plant is being converted from constant flow primary system to a variable primary flow system.

All terminal unit pneumatic controls will be converted to DDC by Andover manufactured Schneider Electric (existing HVAC control system).
