Major Projects

The United States Botanic Garden (USBG) and Architect of the Capitol (AOC) has restored the deteriorating stone façade and roof of the historic USBG Conservatory.

The U.S. Capitol Visitor Center redesigned Exhibition Hall. Visitors can now encounter a dynamic and educational environment that will inform, involve and inspire them about Congress' role in the democratic process.

This project replaced trees at the U.S. Capitol Visitor Center (CVC) entry to recapture the historic design intent and restore the historic character and contributing features of the original Olmsted landscape within the context of the current landscape conditions.

The Architect of the Capitol (AOC) completed a Long Term Strategic Energy Plan for the Capitol Power Plant (CPP), which identified cogeneration as the preferred solution for achieving energy savings, reducing environmental impacts, and maintaining a reliable source of chilled water and steam for Congress and the Supreme Court.

The Supreme Court Building's west front façade has undergone a complete restoration to address deterioration due to age, weather and nature.

The Architect of the Capitol recently completed a multi-year project to completely restore the Dome for the first time since 1959-1960.

In 2017 the Architect of the Capitol completed a long-term conservation effort to restore the murals of the Brumidi Corridors on the first floor of the U.S. Capitol's Senate wing.

As part of this project, completed in 2015, the AOC also installed a 148 kW photovoltaic system on the Hart Senate Office Building roof. The solar panels will decrease utility use, increase sustainability and make the building eligible for an energy credit program which will further reduce electrical costs.

The Ulysses S. Grant Memorial is regularly maintained to keep it in good condition.

The four clouds were lowered to the ground and fully assessed to ensure their structural integrity, including analysis against seismic design considerations. This project was completed in 2016.

The Architect of the Capitol continues to improve the accessible pathway for the Capitol campus.

The United States Botanic Garden (USBG) and Architect of the Capitol (AOC) have made improvements to provide a safe and accessible route from Bartholdi Park to the American Veterans Disabled for Life Memorial and upgrade the aging infrastructure of the historic Park.

The Statue of Freedom is regularly maintained to keep it in good condition.
