The Puget Sound region is known for a few things—beautiful mountains, green forests and bad traffic. Holmberg Mechanical won a $6.5 million contract to build an open tunnel for a light rail system scheduled for completion in 2023 that will help fix the traffic situation.
The project involves ten ACU with roof-mounted condensing units, 13 unit/wall/ceiling mounted heaters, two stair pressurization fans, 20 exhaust/supply fans, 44 motorized dampers, several fire smoke dampers, 60 GRDs and associated ductwork.
