  1. Securing the Built Environment Columbia/Wharton-Penn Roundtable Risk Management Strategies in an Uncertain World Michael J. Garvin Assistant Professor Department of Civil Engineering & Engineering Mechanics Columbia University

  2. Character • Multi-scale Systems • Network: Miles • Contaminants: Microns • Interdependencies & Interactions • Engineering systems • Social, economic & urban fabric • Complex & Dynamic Garvin/Civil Engineering/Columbia University

  3. Vulnerabilities Deterioration Socioeconomic Flux Natural Events Built Environment Technological Change Criminal Events Garvin/Civil Engineering/Columbia University

  4. Measures of Effectiveness • Traditional • Serviceability: satisfactory service to “user” • Reliability: probability of adequate service • Maintainability: effort required to sustain service • Efficiency: effective utilization of resources • Emerging • Sustainability • Security Garvin/Civil Engineering/Columbia University

  5. “New” World? “On Sept. 11th, the vulnerability of infrastructure didn’t change. Principally what changed was our perception of the threats.” Robert Prieto Parsons-Brinkerhoff Garvin/Civil Engineering/Columbia University

  8. Prepare ToolsTechnology Learn Mitigate Manage • Sensors • Monitoring • Control • Information/Software Systems • GIS • Gaming/Simulation of Response Efforts Garvin/Civil Engineering/Columbia University

  9. Issues • Target Rich Environment • Resource Constraints • Existing Assets vs. Proposed Assets • Independent Actors w/ Varying Objectives • Unexpected Consequences of Engineered Solutions • Predictions Are Often Wrong • Decisions Must Be Made • Skepticism of Models • Prescriptive Building Codes Garvin/Civil Engineering/Columbia University

  10. Some Questions • Where Are Structural Solutions Appropriate? • Where Will Capital Come From? • What Can U.S. Learn from International Community? • What Can U.S. Learn from its Own Military? • “Practicing” game theory to prepare and deploy people & technology in high stake environment in an open society for 225 years Garvin/Civil Engineering/Columbia University

  11. Some Questions • What Can We Learn from the Artificial Intelligence/Cognitive Sciences? • How Do We Share Information/Data Pre & Post Event? What Are the Liability/Security Issues? • How Should We Modify Building Codes/Design Standards? • How to Improve Response Efforts? Garvin/Civil Engineering/Columbia University

  12. Opportunities Abound • Data Collection, Management & Utilization • System Characterizaton & Modeling • Institutional Change & Management • Valuation & Finance Garvin/Civil Engineering/Columbia University

  13. In the end, I was discouraged that the civil engineering experts offered no fresh insight about the nation’s infrastructure needs in response to the profound shifts underway in our economy, technology, demographics, and culture. There was no sign that they critically examined their own fitness in terms of professional education and practice--now and in the future--to make this judgement at all. If anything, civil engineering appears to be a dwindling star among the pantheon of higher education engineering specialties as many students turn away from its mechanical, code-bound model of problem solving. So where will the next generation of infrastructure visionaries come from? Maybe from outside the profession entirely.
