Mirroring the development of this project in cooperation between the College of Engineering and the Richard Blum Global Poverty Initiative, this building combines a modern new facility with the retrofit and restoration of a historic UC Berkeley gem.

How do you make an historic building and new addition look like they belong together?

René Vignos is a Principal and licensed structural engineer at &nbsp;Forell | Elsesser. After entering the firm in 1999 and after more than two decades of experience, he is still invigorated by the challenge of creating the most elegant, inspired engineering solutions possible to translate an architect’s vision into a constructible reality.



As &nbsp;Forell | Elsesser’s Chief Operations Officer, René Vignos serves as part of the executive management team that guides the firm as a whole in addition to his responsibilities overseeing the operations of the core engineering practice.&nbsp; His skills in organization, administration, and collaboration serve him well as one of the leaders of the firm.



René has developed broad engineering skills in new design and retrofit, with a specialty in preserving and protecting historic landmark structures. He is currently providing state-of-the-art structural engineering design services for the complex rehabilitation and seismic strengthening of the historic Salt Lake Temple of the Church of Jesus Christ of Latter-Day Saints. This project involves the unprecedented base isolation and retrofit of a massive unreinforced stone masonry structure. In addition to his cultural facilities experience, he also works on athletic facilities, education facilities, national laboratory facilities, and overseas earthquake reconnaissance efforts. René is a licensed Structural Engineer in California, Utah, Oregon, and Wyoming. He has a Bachelor’s degree from Cornell University and a Master’s degree from the University of Texas, Austin.



In his downtime he enjoys tinkering with home improvement projects, camping with his family, and following the latest NHL hockey game.

René Vignos

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.



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.



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.
