P01- SOW 648-22-104 CORRECT HVAC DEFICIENCIES.pdf

This document is a Scope of Work for a HVAC upgrade project (Contract #648-22-104) in Vancouver and Portland, focusing on correcting HVAC deficiencies. The project will upgrade aging Air Handling Units (AHUs) in buildings 1 and 11, replacing exhaust fans and converting from pneumatic to digital controls to improve efficiency and reduce maintenance downtime. Key technical requirements include upgrading fans with new Fan Walls, installing frequency drives, implementing direct digital control (DDC) for dampers and air handling units, replacing sensors and temperature monitoring equipment, and adding new monitoring systems like current switches, static pressure transducers, and humidity sensors.

The work must be performed with minimal disruption to Medical Center Operations, with strict scheduling constraints including 4-hour maximum downtime windows during weekdays and maintaining full facility operation during the upgrade. The contractor is responsible for comprehensive installation, including re-insulating modified areas, routing signal wires, programming control points, and ensuring all new equipment is properly labeled and commissioned. The project emphasizes minimizing AHU downtime and ensuring seamless integration of new HVAC control and monitoring technologies.
