The structural engineering profession has been using SP3 for resilient design and high-fidelity seismic risk assessment since 2014. The SP3 team has worked continually with these visionary structural engineers, to iteratively vet and refine both the software and the underlying seismic risk assessment methods. The SP3 we have today is a result of these countless hours of vetting and contributions from our structural engineering partners (now for over 10+ years!), with the most notable direct contributors listed below. Please let us know if you have contributed and we are missing your firm!

Major Structural Engineering Contributors:

• Degenkolb (first license holder in late 2014, countless technical feedback over the years)
• John A. Martin & Associates (collaborated in major expansion of Building Stability Module in the SP3-RiskModel and SP3-Batch)
• KPFF (leader in Resilient Design for Functional Recovery and countless hours of vetting and refinement provided)
• Magnusson Klemencic Associates (MKA) (leaders in the development of FEMA P-58)
• Mar Structural Design (countless hours and technical feedback on resilient design of new buildings)
• Partner Engineering and Science (collaborated on development of the SP3-SiteHazards module, leaders in PML use)
