Principal

Jacobs Associates principal and vice president Steve Klein is guided by more than 25 years of engineering experience. He has led the planning, design, and construction of more than 1000 tunnel projects, including tunnels for water supply, wastewater, power, highways, and mass transit. 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. Mr. Klein has worked on difficult tunnel projects in urban areas where issues of settlement control, minimizing construction impacts, and performance safety are critical. 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 the lead geotechnical engineer for the Bay Tunnel segment of Bay Division Pipeline 5 (part of the Hetch Hetchy Water System upgrade). He is also the Jacobs Associates project manager for design of the Caltrain Downtown Extension tunnel to the new Transbay Transit Center in downtown San Francisco. He also serves as Jacobs Associates’ principal-in-charge for the Los Angeles County’s new Ocean Outfall, the Route 710 Highway Tunnel in Los Angeles, and the Irvine Corona Expressway Tunnel in Riverside and Orange Counties.

Mr. Klein has published more than 30 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 civil engineer in California, Oregon, and Utah and a registered geotechnical engineer in California.
