Peterson Structural Engineers (PSE) is a single discipline structural engineering and consulting firm specializing in municipal structural evaluations and design particularly in high seismic regions. The company was founded in 1967 by Gary Peterson, whose fastidiousness set the stage for the principles in which the company continues to pride itself — integrity, dedication, and quality workmanship. To this day, our heart and soul lies in the people of PSE and our commitment to excellence.

Over the last 50 years, PSE has accumulated a wealth of institutional knowledge regarding structure types, building codes, construction standards and building materials, delivering innovative solutions to public sector clients on nearly all types of water and wastewater projects. From seismic resiliency to condition assessments and new structure designs, our depth of experience and expertise is exceptional. PSE’s experience in water-related infrastructure projects includes services for water storage tanks and reservoirs constructed of steel, reinforced concrete and prestressed concrete, with an experience list of over 200 reservoir projects completed to date. Additionally, PSE has provided design and consulting services for a multitude of above and below grade pump stations and lift stations, water treatment and wastewater treatment plants, equipment anchorage, basins and contact chambers, pipe bridges, caissons, vaults and culverts as well as various other water related structural elements.

PSE’s depth of knowledge of structural engineering allows us to respond to complex projects, big or small, within Orange County and throughout the Southern California region.
