Russell Corner Security Installation

Washington, DC

While enhancing the perimeter security for this important building, Conti ensured its accessibility to all by incorporating ADA compliant ramps into the design.

The Russell Senate Office Building, named in honor of Senator Richard Russell Jr., was opened in 1909 and is the oldest of the senate office buildings, which were conceived to mitigate overcrowding in the Capitol Building. The 9/11 attacks necessitated that temporary security measures be placed along the street corner at the intersection of Delaware and Constitution Ave, directly in front of the main entrance to the building to prevent vehicles from ramming the building. Conti replaced these temporary measures with government supplied permanent K crash rated bollards.  

The Conti design-build team detailed the AOC provided conceptual drawings and made modifications as needed. For example, during the design and site investigation process, the team discovered that unanticipated underground utilities meant that the bollards grade beam could not be lowered to allow for the depression in the sidewalk needed to accommodate the ADA complaint ramp in the design. Working with the AOC, Conti evaluated the mitigating options, determined the most cost effective method, and proposed the change. Our efforts maintained the ramp’s functionality while keeping the bollard spacing at a consistent distance and compliant with the K crash rating.

Conti worked to ensure that materials and finishes used matched the existing site materials. The team’s efforts resulted in a seamless transition and uniform look in the work zone and surrounding areas.

While performing the work, Conti provided temporary street and signal lighting to ensure pedestrian and motorists safety at this busy Washington, DC intersection
