King County Transit, Maintenance Building HVAC Upgrade

As the prime consultant, FSi provided the project management and mechanical design for the renovation of the Maintenance Building at King County Transit’s Atlantic Base.

This $4,000,000 project replaced all existing airflow and heating systems. Thirteen existing steam heated heat and vent units were replaced with a combination of indirect and direct-fired gas heat and vent roof mounted units which included air to air heat exchangers to conserve heating enrgy. Office and locker room air conditioning systems were replaced. Several exhaust systems were upgraded to provide more consistent flow and capture. Specialty areas included the steam cleaning bay, paint bay, main shops with vehicle exhaust, and a propane back-up heating system. A new boiler was added to provide heating for the office area. All new DDC controls were provided as part of the project.
