Two of the three chillers serving several wards at Eastern State Hospital failed and needed to be replaced. Due to the failures being an unplanned and in summer, the project was designated as an emergency project. The project was limited to like-and-kind replacement, a root cause analysis was not in the budget. During the project assessment and scoping investigation, it was noted the chillers that failed were only halfway through their service life. Columbia Engineering Group always keeps the best interest of our Clients a our top priority and we were not satisfied with simply replacing the failed chillers without first understanding why they had failed prematurely. CEG analyzed the existing installation and found the close proximity of the solid walls to the chiller did not provide sufficient airflow and heat dissipation resulting in the chillers failing prematurely. CEG engineers discussed the issue with the DSHS program project manager and worked to find a cost-effective solution to remedy the situation. The approach was to remove a section of the solid wall and replace it with cyclone fence to improve airflow. During the design phase CEG also provisioned for permanently installed infrastructure to connect temporary chillers in case of any future failure to allow for rapid restoration of service. During the construction phase, CEG worked with DSHS and the Contractor to derive a phasing sequency with temporary equipment to maintain occupancy of the wards. Columbia Engineering Group performed the mechanical, electrical, and structural engineering for this project.
