<p>Located in a seismically active region, the building was designed to meet University seismic requirements that exceed the California Building Code in order to enhance life safety and minimize damage in a seismic event. Strategies included the use of simple, self-bracing forms and high-efficiency seismic systems.</p>


How do you repurpose an underutilized 11,000 sf site, optimizing space within a compact 24,000 sf building?


<p>Chris Petteys serves as the fourth CEO in &nbsp;Forell | Elsesser’s six decades but drives the firm in collaboration with the rest of the executive management team. With a collective focus on building upon the firm’s strong reputation for technical leadership in seismic design, growing talent from within, and creating new opportunities and career paths for staff; Chris leads a firm rooted in engineering fundamentals, client service, performance-based design, and sustainable/resilient structures. From his experience leading large, complex structural projects, Chris has proven the effectiveness of his hands-on management style and enjoys interaction with clients and partners.</p>



<p>In his twenty years practicing as a structural engineer, Chris has navigated complex issues with a level head and taken unexpected approaches to successfully solving problems. He has a broad knowledge of all major construction materials for commercial, multi-family housing, and institutional structures; and is recognized for his efficient buildings and constructability of his designs for unique structures in high seismic regions. His more notable projects include the UC Berkeley California Memorial Stadium seismic upgrade and LinkedIn Middlefield Campus. Chris has both a Bachelor’s degree and a Master’s degree from UCLA.</p>



<p>When Chris is not working through creative solutions or managing the firm, he enjoys golfing, skiing, and spending time with his family.</p>

<p>Masume is a Principal and licensed Structural Engineer at Forell | Elsesser who brings over 16 years of experience and a breadth of knowledge that includes all major construction materials for educational, cultural, laboratory, and commercial buildings. She is proactive in her problem-solving approach and always looks at an issue from different perspectives to find the most appropriate solution.</p>



<p>Masume possesses a broad skill base in the seismic analysis of structures including linear, nonlinear, static, and dynamic analysis techniques. She has experience with foundation design including various piling systems, pre-stressed and reinforced concrete design, steel design, viscous dampers, and Buckling Restrained Braced Frames (BRBF). She has particular expertise in data analysis and advanced computer modeling of buildings. In particular, her modeling of earthquake loading is used to demonstrate structural capacity and pinpoint the deficient areas of a building requiring retrofit work. Masume earned a Bachelor’s degree from Sharif University of Technology in Iran, and obtained Master’s degrees at both the University of Arizona and UC Berkeley.</p>



<p>Masume enjoys hiking, yoga, and Persian calligraphy. She is passionate about what she does—so much that she recently finished a seismic hazard analysis on her own home.</p>

<p>With the firm since 1984, Mason is a Senior Principal at Forell | Elsesser. One of Mason’s most effective roles at the firm is orchestrating teams of engineers to leverage their varied areas of expertise, and quickly develop solutions to even the most complex problems. He constantly explores solution concepts and ideas that are outside the norm, leading to unexpectedly elegant and efficient solutions–a practice he encourages with those he mentors. Mason has also had success in crossing lines between engineering disciplines and construction processes to improve existing structural engineering methods to the benefit of F/E’s clients.</p>



<p>As a well-known industry leader, Mason is a resource for in-house staff and colleagues. His engineering expertise includes such diverse areas as sustainable concrete mix design, seismic isolation of new and historic buildings, long-span bridge design, and performance-based seismic design of steel structures. He excels at the analysis, testing, and design for unusual projects that fall outside the scope of traditional building codes. In the early 1990’s, he developed specifications and testing requirements that were used for the U.S. Court of Appeals seismic retrofit in San Francisco, the first federally funded seismic isolation project.&nbsp;Mason is&nbsp;a licensed Structural Engineer in California, Florida, Hawaii, Idaho, Oregon and Washington, and licensed Professional Engineer in D.C. Mason earned a Bachelor’s degree in Architectural Engineering from Cal Poly San Luis Obispo and a Master of Engineering degree in Structural Engineering and Structural Mechanics from UC Berkeley.</p>



<p>Mason’s recreational interests include hiking, fly fishing, cinema, metalworking, and carpentry.  He sometimes integrates the latter two interests into his structural engineering practice by building physical models of structures and structural hardware to quickly enhance the clients’ and colleagues’ grasp of complex structural concepts.</p>
