Project Background This project is to update the HVAC controls to improve energy efficiency and simplify operational control of the units. The Cooling units were replaced in 1997 and a Control System was installed at that time. In 2026 ODOT replaced the Cooling units with Valent VR-400-30L-0-G0 units.

Project Description:

This project includes the design and implementation of a DDC control system like for like at Building A utilizing Automated Logic Controls. The system must meet the attached specifications to ensure seamless integration and operation. This new system will be to replace the existing outdated control system. New system must be installed in a way that does not interrupt the climate control of the building, or the Contractor must provide auxiliary heating or cooling to accommodate required building temperatures. The current system is tied in with Building B. Building B must be able to work independent of Building A upon completion of the project and is also a requirement of this project. Work to be performed between the hours of 5PM and 6AM. Work to include the replacement of these listed controllers:

· SF1-American Auto-Matrix GPC1 located in RTU

· SF2-American Auto-Matrix GPC1 located in RTU

· Boiler-American Auto-Matrix GPC1 with IOX2 Expansion Module located in control compartment of boiler room on west wall

· VAV Conrollers serving SF1-American Auto-Matrix SBCVAV controllers 1 each for 15 vav’s located first and second floors above ceilings

· VAV Conrollers serving SF2-American Auto-Matrix SBCVAV controllers 1 each for 21 vav’s located first and second floors above ceilings Oregon Department of Administrative Services (DAS) HVAC Controls will provide a detailed sequence of operations that runs all of the building equipment currently for a contractor to replicate

Contractor Coordination required during Construction with DAS to remove necessary points, programs, groups and controllers out of the existing SAGE and relocate it over to Building B until that control system is replaced.
