Neville J. Mathias is an Associate Director with the San Francisco office of Skidmore, Owings & Merrill LLP (SOM). He holds a Bachelor’s degree in Civil Engineering from Madras University in India and joined SOM in 1985 after completing Master’s degrees in Structural Engineering and Architecture at the University of California, Berkeley, USA. Neville is deeply committed to integration and innovation in structural engineering and many of the projects he has been associated with have won awards for excellence in design. Neville has worked extensively on tall, complex and large-scale building projects across the US and around the world. His portfolio includes new buildings as well as retrofits that span a wide range of building functional types, materials, and structural systems. Many of Neville’s projects have required the use of non-prescriptive / performance-based design approaches. His recent projects include the 153 m tall Poly International Plaza diagrid structure in Beijing, China, the 412 m tall sculpted concrete Al Hamra-Firdous Tower in Kuwait, and the 337 m tall steel plate shear wall Jinta Tower in Tianjin, China. He has participated in authoring numerous papers and publications including the San Francisco Building Code’s “AB-083: Requirements and Guidelines for the Seismic Design of New Tall Buildings using Non-Prescriptive Seismic-Design Procedures” and the CTBUH’s “Outrigger Design Guide.” Neville is a member of the Bureau of Indian Standard’s Tall Buildings Sub-committee, CED 38:5, developing a 'Code of Practice for Structural Safety of Tall Buildings' and is also a member of the CTBUH Seismic Working Group developing a guide for “Performance Based Seismic Design (PBSD) of Tall Buildings.” Neville has participated in seminars and conferences all over the world, has been a lecturer at the University of California, Berkeley, and takes an active interest in research and teaching in collaboration with local Universities.
