Thomas P. O'Neill Federal Building Perimeter Security Project

SGH identified locations and magnitudes of vehicle impact threats. We commissioned a non-destructive subsurface investigation to determine the locations of buried infrastructure elements, many of which predated the building’s construction in the mid-1980s. Based on the survey and threat analysis, SGH identified crash-tested bollards that could fit within the site’s constraints, while meeting Department of Defense and Federal Protective Services standards for perimeter protection of federal buildings.

We collaborated with federal agencies, the Boston Water and Sewer Commission, the Boston Transportation Department, and the City of Boston’s design consultants to coordinate our design with below-grade utility vaults and crossings, the city’s pavement design, new landscape features, and accessible access routes around the building. SGH prepared contract documents specifying the bollards’ type and locations and presented our plans to the City of Boston’s Public Improvement Commission.

We also provided post-construction contract services, including reviewing the contractor’s design and shop drawing submittals and making periodic site visits to observe construction progress.
