McMillen Jacobs Associates promotes three associates to principal



McMillen Jacobs Associates recently announced the promotions of these three engineers to the position of Principal: 
Mark Lawrence, PE specializes in the design of permanent and temporary excavation support systems. With over 35 years of experience, he leads the excavation support design group in the San Francisco office. In 2011, Mark was the first recipient of the James Wilton award, an employee award honoring the memory of James Wilton, former principal and president of Jacobs Associates. Mark’s experience spans a multitude of projects. Notably, he provided design of slurry wall shaft excavation support systems for the Nicolai, pump station shafts for the Willamette River CSO Project, and the pump station shaft for the Brightwater Conveyance System. The Willamette Pump Station is still the largest-diameter slurry wall shaft constructed in soft ground in North America. Mark’s more recent work includes a dual-cell slurry wall shaft for the Watercare project’s Mangere Pump Station, a 110-foot-diameter by 94-foot-deep CSM shaft for the Humboldt Bay Power Plant decommissioning, several deep excavations in San Francisco for new underground space, and assistance with the declines in Sydney.
Jan Van Greunen, PhD, PE, has more than 40 years of  experience in conceiving, planning, managing, and coordinating analysis, design, and construction of civil engineering works and complex steel and concrete structures and is based out of the San Francisco office. Jan has provided structural design expertise and leadership on some of the firm’s largest and most complicated projects, from a structural perspective. This includes the Rondout-West Branch Bypass Tunnel, where the lining must resist an external water head ranging from 600 to 900 feet; the Caldecott Fourth Bore, which is close to the Hayward Fault, resulting in high seismic demands; the Claremont Bypass Tunnel, which crosses the Hayward Fault and includes a vault to accommodate the anticipated 8 feet of fault offset; and the Airport Link Caverns, which required span widths of up to 85 feet in plain concrete
John Waggoner, PG, CEG, has over 35 years of experience in the application of engineering geology to a diverse array of public and private sector civil engineering projects, including underground construction projects, dams and reservoirs, pipelines, highways and bridges, dewatering systems, and hazardous waste sites. Based in the Pasadena office, he applies geologic factors to the permitting, design, and construction process and has used this expertise to avoid or minimize complications during construction on many signature California projects. These include the San Jose to Merced leg of the California High Speed Rail Project, the Arrowhead Tunnels, and numerous assignments for LA Metro and MWD. John’s work on the Newhope-Placentia Truck Sewer Replacement design project in Orange County and the Chevy Chase Sewer construction management project in Glendale helps maintain his market understanding across Southern California.
Based in San Francisco, McMillen Jacobs Associates is an employee-owned environmental, engineering, and construction company providing a comprehensive array of technical services to the heavy civil, underground, and water resources markets. For more information, visit www.mcmjac.com.
