As Director of Structural Engineering in the San Francisco office, Eric Long incorporates innovative structural engineering design concepts to drive new solutions in building design and construction. Long works in close collaboration with the entire design team, including architectural and MEP, to develop integrated ideas and advance each project in pursuit of design excellence. He maintains this focus through the entire structural design process, from the development of the structural concept and selection of building systems, through final construction documentation and administration.

Long's project experience includes the design of office, residential, and multi-use mid-rise and high-rise structures, in addition to complex multi-building developments. Notable projects include the United States Embassy in Beijing, the Cathedral of Christ the Light in Oakland, 350 Mission Street in San Francisco, and the New Federal Courthouse in Los Angeles. Long has successfully incorporated innovative and technologically advanced structural applications into the design of these projects including seismic base-isolation, long-span cable structures, integrated glass curtain wall systems, and performance-based seismic design.

Long is involved in teaching an integrated architectural studio class, focusing on the creative collaboration of architecture and structural engineering, with students from Stanford University; University of California, Berkeley; California Polytechnic State University, San Luis Obispo; and California College for the Arts. Long frequently lectures on a wide variety of topics including the application of advanced technology in design, seismic performance and resiliency, and the unique design solutions of individual projects.
