Protective Design

Our approach to each facility begins with our mission to safeguard the life, health, property, and welfare of the public through thoughtful design methods that reduce the risk and vulnerabilities of the structure and end user. LBYD Engineers understands the risks associated with terrorism are paramount for the protective design of facilities. We work closely within the design team, end user, and owner to understand the facility needs, make informed protective design decisions, and implement strategies that increase the safety of the end user.

Protective Design

Anti/Terrorism Force Protection

LBYD has provided consulting engineering services for numerous military and federal facilities throughout the country. Through this experience, we bring knowledge and technical expertise to the design team to manage requirements of the user with security and safety issues unique to each facility’s design criteria, while maintaining functionality and cost efficiencies. LBYD provides design consistent with installation master plans, following their roadmap for compliance with UFC 4-010-01, DoD Minimum Anti-Terrorism Standards for Buildings.

 Using guides such as the Unified Facilities Criteria (UFC) 4-010-01 Minimum Antiterrorism Standards for Buildings, UFC 3-340-01 Design of Hardened Structures to Conventional Weapons Effects, UFC 4-022-03 Security Fences and Gates, and other criteria developed by the DOD, LBYD proactively assists the AE team with site planning, selection of building materials and design for Anti-Terrorism/Force Protection (AT/FP).

LBYD is an active member of the Society of American Military Engineers (SAME) and has provided consulting design services in a variety of project delivery types ranging from Prime Consultant Design/Bid/Build, Design/Build, and blast engineering expert consulting.

We have completed projects for the following:

  • US Army Corps of Engineers
  • Naval Facilities Engineering Command (NAVFAC)
  • United States Air Force
  • United States Marine Corps
  • US Department of Veterans Affairs
  • US General Services Administration
  • Department of Corrections
  • Federal Bureau of Prisons
  • Department of Criminal Justice
  • National Aeronautics and Space Administration (NASA)

Blast Engineering

Based on a building’s threat assessment, LBYD provides blast engineering in accordance to UFC 4-010-02 and UFC 3-340-1. LBYD’s experience, knowledge of the anti-terrorism force protection requirements, and team oriented design methodology is an essential part of any blast protection project. Depending on the site design, the role of the structural engineer varies from designing windows in the building envelope to hardening the structure and analyzing for global blast effects, internal and external blast effects on building components, and progressive collapse.

Services include:

  • Far-field and close-in-air blast load prediction
  • Single degree of freedom (SDOF) design process
  • 3D building performance visualization
  • Confined explosion effects
  • Non-linear dynamic analysis
  • Structural modeling and design
  • Facades modeling and design
  • Fragmentation effects
  • Shock and impact modeling
  • Conventional weapons effects

Progressive Collapse

Progressive collapse analysis is the analysis of the building when a specific column or beam is removed. The remaining components of the building must be capable of stabilizing the building and preventing its collapse. Progressive collapse is required to be performed on any inhabited structure with three or more stories or structures with overhangs with inhabited space above the overhang (UFC 4-010-01).

Perimeter Security Design

The first line of defense in protective design is the protection of the facility perimeter. With our experience in federal and other secure types of projects we bring an understanding to the design team that is included in the comprehensive security design. Whether considering natural or structural barriers, or providing landscaping elements and forms, or a perimeter fence and gate system, we provide designs to delay or deter unwanted pedestrian and vehicular intrusion. Our engineers work seamlessly with the design team to provide effective and integral access control, enforceable clear zones and standoffs, and clear wayfinding that also allows for effective surveillance.
