UFC 2012: Implications You Need to Know Regarding Window Design!

by Hinman Team

The new UFC has a strong start, presenting designers with modified site requirements that reduce perimeter standoff distances.  A change welcomed by design professionals.  However, don’t be too quick to celebrate.

The Hidden Cost of Saving Money

by Hinman Team & Brian Katz

Early this year, the new Department of Defense Anti-terrorism/Force Protection (AT/FP) standards (UFC 4-010-01) were adopted.  The stated impact of the document on new and existing construction is “most of the changes should result in cost savings or no change in costs”.  Over a series of blog posts, I will explore the implications of this new criteria to determine if this intent is indeed the reality.

The Effect of Fire Following an Extreme Event

by Hinman Team

The ability of a structure to resist a disproportionately large collapse due to localized damage (i.e. progressive collapse) has become a topic of increasing concern within the building community in the wake of structural collapses worldwide over the last half century… The goal of this study is to raise awareness of potential fire hazards that may follow extreme events and provide recommendations regarding evacuation times for occupants of damaged buildings under fire.

Terrorist Risk Assessment and Mitigation of Bridges

by Hinman Team

In 2003, the Blue Ribbon Panel on Bridge and Tunnel Security issued its recommendations for risk assessment and mitigation of bridges and tunnels.  The report gives general guidelines to help decision makers improve the security of bridges and tunnels.  However, the actual implementation can be highly dependent on the methods used to carry out the assessment.

Performance Limits for Progressive Collapse

by Hinman Team

Progressive collapse is an extreme loading event that requires identifying and engaging all necessary and available load paths within a structure.  Most recently, Hinman engineers have conducted a nonlinear dynamic finite element analysis of an existing 33-story high rise structure with the intent of pushing the limits of structural performance.  Hemmed in by the constraints of the current governing criteria, project engineers found structural performance to be limited by the required use of seismic documentation.  When costs and upgrades are a concern, and collapse is the question, it appears to be necessary to redefine the problem of progressive collapse.

ATFP Design of Military vs. Civilian Federal Facilities

by Eve Hinman

I had the honor of providing expert testimony to the U.S. House of Representatives Committee on Transportation and Infrastructure on the risk implications of applying the DoD Minimum Antiterrorism Standards for GSA lease procurements. The House is concerned about the cost of providing the large setback distances required by DoD standards for new facilities housing “back office” DoD operations located within an office park or downtown location with an uncontrolled perimeter.

Overview of new ISC Physical Security Criteria

by Shalva Marjanishvili

The new ISC Physical Security Criteria for Federal Facilities (April 12, 2010) has some significant changes from the previous version. There are larger threat sizes, but the approach is more flexible and allows for cost-risk decision making on a project by project basis.
