  10. 10. • Envisioned to be an authoritative, nationally and internationally recognized professional certification• Will assure owners, public officials and the general public of the competence of professionals designing, constructing and managing infrastructure projects• The professional engineer (or other licensed infrastructure professional) will be PCSE certified• Scheduled for launch in the 1st quarter of 2012
  11. 11. • Formally launched in February 2011• Collaboration between ASCE, APWA & ACEC• Core Products and Programs – Rating System, including software application – Education and training – Professional (individual) certification – Project awards at various levels of performance
  12. 12. • Holistic, transformational approach – Performance-based (outcomes) rather than prescriptive – No other U.S. programs currently fulfilling need• Consider Triple Bottom Line• Similar to LEED but focused on civil infrastructure• Incorporate/reference existing rating systems, as appropriate – CEEQUAL (UK)• Scalable for size and complexity of projects• Adaptable for specific needs and circumstances – Provide for self-assessment, as well as independent verification• Voluntary
  13. 13. • Two-pronged purpose – Ensure that the project makes performance contribution • Contributes to sustainable performance improvement • Does things right, raises the bar – Ensure that the project makes a pathway contribution • Provides net contribution to affected community • Does the right thing, community-focused• Voluntary – Submit detailed design information – Evaluate against standardized criteria
  14. 14. • Project Management – Demonstrated Need For Project – Site Selection – Design Optimization – Best Practices to Deliver Social/Community Benefits• Efficiency of Land Use• Protection of Critical Lands (floodplains, prime farmland) – Contaminated lands – Floodways and Floodplains, wetlands
