Hart Tunnel and Russell Courtyard

Washington, DC

Two of the Capitol's most attractive and useful buildings required improvements to enhance security perimeters.

Built in the early 1900s, the Russell Senate Office Building stands as a testament to the era’s majestic architecture. However, the courtyard was in need of upgrades due to its aging security system. Similarly, the Hart Tunnel, entrance to the Hart Building’s underground parking garage, suffered from ineffective traffic barriers.

For the Russell Courtyard, the team replaced an old wooden shed with a bulletproof security police shelter, removed an old barrier and installed a brick driveway in its place while carefully protecting the historic archway.

For the Hart Tunnel, the team removed and replaced barriers to create a sally port for vehicles. The sally port required a set of barriers that raised and lowered so the entrance is always protected and secured.

Conti worked in off hours to accommodate government personnel needs, resulting in a successful project and a strong relationship with the client.
