Additional Information

I serve as President and Chief Technical Specialist for Caprock Engineering, PLLC, and as a Principal Engineer with Systra-IBT. I have over thirty years of experience in structural bridge design. My LinkedIn profile is at https://www.linkedin.com/in/scottphelan-caprock. I serve on the international American Society of Civil Engineers (ASCE) Transportation & Development Institute (T&DI) Economics & Finance Committee, the national Precast/Prestressed Concrete Institute (PCI) Bridges Committee, and the regional American Council of Engineering Companies/ Washington Department of Transportation (ACEC/WSDOT) Structures & Geotech Subcommittee. I recently was inducted as an ASCE Fellow. I have participated in the design and construction of numerous concrete segmental bridge projects, including the final design of two world-record bridges and the construction of the first precast concrete segmental bridges in the State of Washington. I recently served as Co-Chair of the Seattle DOT Technical Advisory Panel (TAP) for the West Seattle High-Rise Bridge Repair/Replacement study and was instrumental in assisting the Engineer of Record in arriving at a repair solution that saved the City over $400M. I have been awarded three U.S. Patents on cable stay vibrations (now expired) — two on wind-rain mitigation solutions for cable-stayed bridges and one for vortex-induced vibration suppression for offshore cable-stayed structures. I have participated in value engineering studies as the structural engineer for the Washington State Department of Transportation, WSDOT, and for Sound Transit, the regional transit agency for Seattle, WA. I currently am working as a Principal Engineer on the progressive design-build Interstate 10 Mobile River Bridge cable-stayed bridge in Alabama, USA with Sytra-IBT. I am licensed as a: Professional Engineer (P.E.) in the States of Washington, Oregon, California, Hawaii, Texas, and Florida; Professional Engineer (P.Eng.) in the Canadian Provinces of British Columbia and Ontario; and Structural Engineer (S.E.) in the States of Washington and Hawaii.
