After completing a POSTDOC in Architectural Engineering at UC Berkeley, I worked for the US Dept of Housing and Urban Development analyzing Native American housing. My findings revealed significant structural defects and lack of habitabilty and inspired me to work with two structural engineers to develop construction methods to reinforce woodframe buildings. I and my colleagues started an engineering construction company that specialized in earthquake reinforcing. In 1989, I completed a book that summarized the important procedures to strengthen buildings particularly in areas prone to earthquakes. Within six months after completing my book, we experienced the Loma Prieta Earthquake.
During the forty years I managed construction at the federal, state,and local levels, we focussed on quality control and construction safety. Our efforts were rewarded with no construction accidents or failures. In 1997, we completed the restoration of the Cache Creek Settling Basin for the Fed...
