New Video: Caltrans Fan Wall Installation Time Lapse

Over the Memorial Day Weekend, the Cooper Oates Air Conditioning Construction Team demolished an enormous (12 ft. x 15 ft., 107,000 CFM) circulation fan and installed a Fan Wall at the Caltrans Headquarters building in downtown Sacramento. The Fan Wall consisted of fifteen individual, 300 lb., fan cubes that provide much needed redundancy and significant energy savings.

NO downtime was allowed for this project which was a critical infrastructure upgrade for an aging, essential services building with over 1,400 employees.

The project began right at 5:00pm on Friday of the Memorial Day Weekend and was fully installed and ready for tenants by Monday at 3:00pm.

The COAC Installation Team just completed a challenging, time-crunched project at the Cal Trans Building across from the State Capitol. The project entailed de-constructing and dismantling an enormous single 12 ft by 12 ft. 100,000 CFM / 60 horsepower circulation fan and replacing it with a more energy efficient and significantly more manageable fan wall. The fan wall was made up of 15 integrated, independently controllable Hunt Air fan cubes that generate as much or more than the required 100,000+ CFM of air flow. The final size of the cube array, not including the supporting steel superstructure, was 16.25 ft. wide by 11 ft. tall. The entire disassemble, removal, preparation of new opening, and installation of the 15 cubes was completed in just under 70 hours during the long Memorial Day weekend with no work disruption to the Cal Trans tenants. All of the month’s long planning, creative solutions and great teamwork certainly paid off. Well done team!
