PB has a strong track record when it comes to incorporating security into infrastructure planning and design. It was amid the nuclear threat of the Cold War, for example, that PB designed the intensely safeguarded, underground Combat Operations Center for the North American Aerospace Defense Command (NORAD). Nearly half a century later, we continue to participate in security-related projects, including an assessment of the unparalleled security measures implemented for the 2002 Winter Olympics in Salt Lake City, Utah. These projects from two centuries exemplify the adaptive, cross-disciplinary nature of all work carried out in the urgent environment of threatened public security.

PB understands the intricate requirements of security-related projects, from threat assessment to blast engineering to smart contingency planning to security training venues. We also understand that the physical vulnerabilities of our infrastructure must be mitigated—a task that goes well beyond site boundaries or construction limits—if current security objectives are to be met.

PB's approach involves up-front assessments of risks and threats to clients' infrastructure, facilities, and services. These assessments can lead to reviews of structural blast resistance; emergency plans; evacuation plans; facility plans and layouts usable by 1st responders; training of infrastructure personnel; and recommendations for changes in site layout and design. The objective is to maintain or enhance a facility's functional uses through security improvements. Other important services include facility inspections, infrastructure rehabilitation, and consequence management.
