Karl joined R+C in 2004 and has experience designing a range of structure types on projects with unique challenges and structural performance objectives. He contributed to the development of state-of-the-art probabilistic methods for assessing the seismic performance of buildings, and he has implemented these advanced methods on several projects to provide efficient seismic retrofit solutions. His recent projects include the PG&E San Francisco Central Services Facility retrofit, Veterinary Medical Building 3B at UC Davis, seismic evaluation and retrofit designs for several concrete buildings at UC Berkeley, and design and consulting for wind and seismic analysis of rooftop solar arrays throughout the U.S.
Karl is active in research projects and development of industry standards. He has contributed to several publications including the Structural Engineers Association of California (SEAOC) Structural/Seismic Design Manual and the journals Earthquake Spectra and Concrete International. In 2010, he completed a Fulbright Fellowship studying structural design and high-performance building materials in Switzerland. He performed post-earthquake reconnaissance work in Haiti following the January 2010 earthquake, and he is currently active in on the ATC-94 project studying lessons learned from the 2010 Chile Earthquake.
