WALTHAM, Mass. - June 14, 2011 -National engineering firm Simpson Gumpertz & Heger Inc. (SGH) announced the promotions of the following employees:

  • David McCormick was promoted to senior principal. Dave has more than 30 years of experience in structural engineering and has been with SGH for nine years. He specializes in seismic engineering and concrete rehabilitation. In addition to the Mexicali and Chile earthquakes, he has investigated the effects of more than a dozen strong-motion earthquakes on structures and nonstructural elements. He has conducted seismic risk assessments and designed upgrades for nearly a dozen Genentech buildings including the recently completed Building 3. For Building 3, Dave led a team that designed an innovative system of spliced buckling-restrained braces. He has also designed four structural retrofits for a large technology firm including relocating critical equipment from a seismically high-risk building to a more secure building.
  • Stephen Harris was promoted to principal. Steve has more than 25 years of experience in structural engineering and has been with SGH for nine years. He has strong technical skills in a broad range of structural engineering applications including building design, seismic engineering, and foundation engineering. Steve has managed very large projects, including the design of a 30-story commercial office building in San Francisco. His current projects include the expansion, remodel, and seismic upgrade of the J. Paul Leonard and Sutro Library at San Francisco State University as well as the fast-track design and construction of 42 new buildings at Marine Corps Base Camp Pendleton in California. The library and the Camp Pendleton projects are both design-build projects for T.B. Penick & Sons.
  • Rasko Ojdrovic was promoted to principal. Rasko has more than 20 years of experience in structural engineering, engineering mechanics, and infrastructure engineering at SGH. He has performed pipe condition assessment and failure risk analysis; investigated failure of concrete, metallic, and plastic pipes up to 12 ft in diameter; and designed repairs of prestressed concrete cylinder pipe (PCCP) using carbon fiber reinforced polymer (CFRP) and post-tensioning. He also participated in research that led to developing the AWWA C304 standard for design of PCCP, the thrust restraint provisions in AWWA M9, and techniques for analyzing the failure risk analysis of PCCP with broken wires. Rasko has performed failure investigation, inspection, condition assessment, and repair design of building structures, antennas, and precision structures. He has also investigated failures and provided litigation support for a wide range of projects including the collapse of the Dallas Cowboys indoor football practice facility.
  • Susan Knack-Brown was promoted to associate principal. Susan has been with SGH for 13 years and has worked on a range of building enclosure investigations and designs involving both contemporary structures, such as the Fisher Center for Performing Arts at Bard College, and historic landmarks, such as Boston's Quincy Market. Susan specializes in large-scale preservation projects where she applies emerging technologies to restoring landmark buildings. Some of Susan's signature projects include the multi-phase, multi-year roof rehabilitation and skylight restoration on the New York State Capitol and the roof replacement on the Massachusetts State House. She has also worked with The First Church of Christ, Scientist to assist them with condition assessments, interim repairs, long-range strategic planning, and restoration designs for the plaza and five buildings on their Boston campus.
  • Sean O'Brien was promoted to associate principal. Sean has 10 years of experience at SGH and specializes in building science and building envelope performance including computer simulation of heat, air, and moisture migration. He has investigated and designed repairs for a variety of building types ranging from condominiums to art museums. Some of his notable projects include: the exterior enclosure system design for the award-winning New Museum of Contemporary Art in New York City; building enclosure design and thermal analysis for the first indoor ski park in the U.S. at the Meadowlands in New Jersey; building envelope consulting for the George W. Bush Presidential Library in Dallas, Texas (currently entering the construction phase); and exterior enclosure systems design for the Yale University Art Gallery renovation in New Haven, Connecticut.
  • Wen-How Tong was promoted to associate principal. Wen has more than 30 years of experience in seismic structural dynamics analysis and has been with SGH for three years. Wen specializes in evaluating the seismic capacities and performance of building structures and equipment for commercial nuclear power plants, Department of Energy facilities, refineries, chip manufacturing facilities, LNG terminals, and hospitals. His recently completed projects include the seismic probabilistic safety assessment (PSA) for Électricité de France (EDF), seismic PSA for EnBW GKN-II nuclear power plant in Germany, and the seismic margin study for the UK EPR (European Power Reactor). Wen has also developed PRA-based seismic margin assessments for the GE ESBWR (Economic Simplified Boiling Water Reactor) and US AREVA EPR (Evolutionary Power Reactor) for applications of Design Certification from the U.S. Nuclear Regulatory Commission.
