Working around the clock, 24 hours a day, seven days a week, the men and women of the AOC Senate Superintendent Office are dedicated to serving the United States Senate by ensuring the historic fabric of the buildings are maintained while meeting modern and evolving workplace needs.

These skilled tradespersons work behind the scenes providing services to the Senate that include: ensuring a safe and comfortable indoor environment; preserving historic structures; maintenance, repair, and construction; and furnishing and care of office suites.
