DeYoung Pavilion Shell and Core Commissioning, Evergreen Hospital, Kirkland, WA
Wood Harbinger was retained by Evergreen Hospital to perform special testing and measurement during commissioning of the DeYoung Pavilion Shell and Core on the Kirkland medical campus. DeYoung Pavilion is a newly-built five story tower that serves as a combination transit hub and medical tower with a two story parking garage underneath. Wood Harbinger provided: commissioning plan development, constructability reviews, test scheduling, pre-functional check procedures, and functional performance testing of mechanical and electrical systems. This building is served by a fan array-based HVAC system with high efficiency boilers and an air-cooled chiller. Wood Harbinger simulated full-load operating conditions to verify the capacity of the plant equipment in the absence of actual building loads, pending tenant build-out. A state-of-the-art Direct Digital Control (DDC) system was used to optimize energy performance and increase equipment life.
Going beyond the typical scope of commissioning, Wood Harbinger provided and executed a measurement plan to verify the capacity of the installed systems under simulated worst-case conditions. This was done to ensure adequate capacity of the shell and core equipment to serve future build-out and tenant improvement. With future systems waiting to be installed there would have been no way to guarantee that the equipment installed in the shell and core phase would in fact be able to meet design requirements. Wood Harbinger was proud to provide this service and provide confidence to the owner that the equipment they were paying for would be adequate.
This 450,000 SF facility houses the Evergreen Neuroscience Institute, providing diagnostic, therapeutic and rehabilitative services to patients living with a variety of neurological diseases and disorders. It is comprised of four programs: Primary Stroke Center, Booth Gardner Parkinson’s Care Center, Movement Disorders Center, and Multiple Sclerosis Center. Due to the critical nature of the processes and tenants expected to be a part of this specialized facility, the emergency systems were also stringently tested. Wood Harbinger wrote and executed a test protocol to simulate a fire alarm condition during a power outage. This test took the building off grid, simulating the power failure, and then into fire alarm mode. The systems were verified to respond properly to the fire alarm simulation, and restart appropriately as the fire alarm was cleared and power was restored. This protocol was included in commissioning documentation and will be used in ongoing confidence testing by the hospital maintenance division. This enhanced testing and validation highlights the flexibility and creativity of Wood Harbinger’s experience commissioning engineers.
