The Architect of the Capitol has a commitment to providing high quality service to its customers.

The AOC serves Congress and the Supreme Court from behind the scenes and receives excellent marks on our annual customer satisfaction surveys for anticipating and meeting our customers’ daily operational and facility needs.

Today, under the leadership of Stephen T. Ayers, Architect of the Capitol, the 2,600 employees of the AOC serve in diverse roles applying both modern techniques and historical tradecrafts in the care and preservation of the Capitol Campus.

The AOC works to: support the needs of nearly 30,000 occupants and millions of tourists who visit the campus annually; ensure the buildings and grounds meet modern standards for sustainability and accessibility; and preserve the historical legacy of the landmarks entrusted to the AOC’s care.

The AOC achieved 90 percent satisfaction for all three main categories of service: interaction with the superintendent’s office, facilities’ physical appearance and environment, and service delivery. The AOC also received a clean opinion on our financial statements audit for the seventh consecutive year.

This demonstrates our commitment to strong financial stewardship that allows us to effectively and efficiently serve our customers by providing Congress and other decision makers with reliable information on program cost and performance.
