Charleston County Detention Center Air Handling Unit Replacement, Leeds Avenue, Charleston – Thomas Brown, Ernest Hilton, Richard Simmons, Richard Johnson, Mike Lenoir, William Mosley, Tom Brawdy and Gary Lindner spent nine days in Penthouse A of the Charleston County Detention Center this past November. Although they had to be escorted at all times by two uniformed officers, they were not there for any illicit transgressions. Cullum was awarded a project that included the change out of four air handling units (AHUs). The schedule allowed seven days to change out two critical AHUs and thirty days to change out two non-critical AHUs. By day nine all four units were installed and running with the two critical units completed by day four. Congratulations on a job done well and completed way ahead of schedule!
