Stephen J. Klein, PE, GE
Principal
Jacobs Associates Principal and Vice President Steve Klein is guided by more than 30 years of engineering experience. He has led the planning, design, and construction of more than 100 tunnel projects, including tunnels for water supply, wastewater, power, highways, and mass transit. and has led the design of several major tunnel projects with construction values ranging from $100 million to over $5 billion. His expertise covers soft ground and rock tunnels, geotechnical investigations, ground characterization, tunnel excavation and support methods, tunnel lining design, and grouting for ground improvement. Projects he has worked on have involved both soft ground and hard rock tunnel boring machine (TBM) methods, conventional drill-and-blast methods, and the New Austrian Tunneling Method (NATM). Mr. Klein also has worked on difficult tunnel projects in urban areas where issues of settlement control and construction impact minimization on the public were critical for project success. Regarded as an expert in microtunneling and pipe-jacking methods, he has taught at numerous seminars and conferences across the country. Mr. Klein is presently managing the tunnel design for the Kaneohe-Kailua Gravity Tunnel project on the island of Oahu in Hawaii. He is also the Jacobs Associates project manager for design of the mined tunnel for the Caltrain Downtown Extension to the new Transbay Transit Center in San Francisco. In addition, he serves as Jacobs Associates’ principal-in-charge for the Los Angeles County’s new Ocean Outfall, the Regional Connector for Metro in Los Angeles, and the New Irvington Tunnel in the East Bay of San Francisco.
Mr. Klein has published more than 40 technical papers on geotechnical engineering, tunneling, and microtunneling topics. He received his MS in Geotechnical Engineering from the University of California, Berkeley, and his BS in Geotechnical and Structural Engineering from the University of Illinois, Champaign-Urbana. He is a registered professional civil engineer in California, Hawaii, Oregon, and Utah, and a registered geotechnical engineer in California.
