Project Images Orange County Regional History Center Project Summary Orange County chose Hanson to perform the re-commissioning of the smoke control system at the Regional History Center in Orlando, Florida. The five-story building was constructed in 1927 as a county courthouse, and the smoke control system was installed in 2000 as part of a renovation that converted the facility into the history center. The bottom four levels contain exhibits, while the fifth floor houses office space and archives. The smoke control system includes stairwell pressurization and smoke evacuation for the historic lobby and exhibit spaces. Hanson’s scope of services encompassed re-commissioning, which included reviewing as-built documents, control drawings and equipment submittals for the commissioned systems; assisting with reviewing the installations in the field; and assisting with developing functional performance tests.
