Engineering the Disaster Site

Next Steps

Structural Engineers Association of Pennsylvania Conference

June 8, 2016Villanova University

Background Information

• George J. Lazorchick, PE, PLS• BSCE Lehigh University 1973• Civil Engineer Contractor to SRBC• Professional Engineer, Surveyor in PA• Structures Specialist with FEMA PA TF1 since 2000• Involved in Emergency Services since late 1960’s

• Emergency Services Instructor since mid 1980’s

Federal (FEMA) Task Force Locations

PA In State System• Formed in Response to September 11 Attack• Statewide System to Address Regional Incidents• Additional Resource for Major Event in PA• Overall Management by PEMA and Local Sponsoring

Agencies• Similar Structure to FEMA teams, however more

adaptable to local needs, such as:o Urban Search and Rescueo Wilderness Search and Rescueo Water Rescueo Medical Supporto Special Events

Interaction with Local Agencies• Pluses

o Situation will more than likely be relatively stableo Someone will be in charge; i.e. a decision makero You will be offering an experienced opiniono You will hopefully be dealing with people that have

some level of technical rescue training• Minuses

o You may be expected to have opinions on or answers to all of the situations posed to you

o You may have difficulty “communicating”, sometimes even the most simplest (to us) concepts

Interaction with Local Agencies

OVERARCHING CONSIDERATION

The SAFETY of yourselfthe emergency responders, and then

any potential victims

Engineer’s Unique Skill Set

• Knowledge and experience in topic areas very few emergency responders are familiar with

• Competent and proficient in performing mathematical analyseso Weight calculations for mitigation / stabilization o Center of gravity estimateso Structure monitoringo Interaction with local agencies / other engineers

Requirements & Training ??????

• Registered Engineer• Incident Command System Online course• Safety Assessment Program (SAP) Evaluator

(ATC20 / ATC45) Training• Willingness and desire to participate

o The extent of your involvement will be directly related to your level of interest

Resources

• Field Operations and Shoring Operations Guides

• Handbook & Online

Resources

• DHS Field Guide for Building Stabilization

• For Use by Non-USAR Engineers

• Some Duplication with FOG & SOG

• More Info on Long Term Stabilization & Mitigation

Most Likely Tasks • Scene Assessment• Weight / Center of Gravity estimates

Structure Markings

• Empty box means relatively undamaged structure or void.

• Evaluate Time and Date

• LOW RISK

Structure Markings

• Single Line means structure is damaged

• Mitigation may be needed

• MODERATERISK
