Simpson Gumpertz & Heger announced its newest Senior Principals, Principal, Associate Principal and Director of Petrography. These individuals possess the expertise and the dedication to SGH and its clients that enable the company’s continued success.
Pedro J. Sifre | Senior Principal Pedro has more than thirty years of experience as a structural engineer. His experience includes new design and renovation of structures for a variety of building types, including institutional, high-rise, industrial, and residential buildings. Some of his recent projects include the new Environment Hall at Duke University, the new library at Salem State University, and the renovation and expansion of the Clinton National Airport in Little Rock. Pedro’s professional activities include participating in the Toolkit Committee at the Council of American Structural Engineers and representing SGH at the Boston Association of Structural Engineers.
Wen H. Tong | Senior Principal Wen has over thirty years of experience in seismic structural dynamic analysis and evaluation of seismic capacities of building structures and equipment for commercial nuclear power plants, DOE facilities, refineries, wafer manufacturing facilities, and hospitals. He has performed and managed seismic fragility and seismic margin evaluations for more than thirty commercial nuclear power plants in North America, Europe, and Asia. His recent work includes seismic fragility evaluations for three operating nuclear power plants in high-seismic zones, seismic response and fragility evaluation of a nuclear power plant under construction in the Middle East, seismic probabilistic risk assessment for heavy water pressurized water reactors, probabilistic seismic response analyses of two European nuclear power plants on deep soil sites, and risk assessments of seismically-induced internal fire and flood. Wen has also provided seismic probabilistic safety assessment, seismic margin assessment, and Seismic Qualification Utility Group (SQUG) training courses to utilities and A/E firms.
Kevin Poulin | Principal Kevin Poulin’s twenty years as a structural designer include projects that range from renovation of existing buildings and design of new buildings to structural peer reviews and feasibility studies. Kevin’s projects include renovation of the Standard Oil Building and the Down Town Association, both New York City Landmarks, and the design of the New Museum of Contemporary Art in New York City. He is the managing editor of the newsletter for CoreNet Global’s New York City chapter and a past president of the Structural Engineers Association of New York.
John M. Porter | Associate Principal John has sixteen years of structural engineering experience designing new structures and assessing existing structures. His work includes performing condition assessments of existing structures, developing rehabilitation programs to repair deterioration and distress, and helping owners prioritize future repair and maintenance needs. Many of John’s projects involve concrete structures, including some of his recent work for the repair and rehabilitation of several parking structures on the Massachusetts Institute of Technology campus, Hawthorne Place plaza and parking garage, and Reservoir Place parking garage, as well as the interim structural stabilization of the Boston Harbor Campus substructure at the University of Massachusetts. John is a member of the International Parking Institute’s Consultants Committee.
Mauro J. Scali | Director of Petrography Mauro is a licensed geologist and concrete petrographer with more than thirty years of experience in the evaluation, testing, and repair of concrete, masonry, stone, and stucco. He manages the Microscopy Laboratory and its team of petrographers. Mauro’s work includes conducting condition appraisals, laboratory testing, and evaluation studies, where he frequently uses traditional and advanced optical and scanning electron microscopy and analytical chemical techniques. He has written and lectured frequently on the topics of concrete petrography and long-term durability performance of concrete and concrete materials. Mauro is a member of the American Society for Testing and Materials and the American Concrete Institute and is a founding member and former president of the Society of Concrete Petrographers. He serves on numerous ASTM International technical committees, including Committee C01 on Cement, and Committee C09 on Concrete and Concrete Aggregates, where he currently serves as a Committee Officer, Chair of Subcommittee C09.20 on Normal Weight Aggregates, and previously served as Chair of Subcommittee C09.65 on Petrography.
