If you’ve ever seen a building go up in Los Angeles, there’s a good chance it started with the work of Marshall Geoscience. Headed by civil engineer and founder Marshall Hayrikian, this specialized geotechnical and environmental firm plays an essential role in making new construction safe, sound, and sustainable.
Marshall Geoscience focuses on two critical services: geotechnical and environmental engineering consulting. For homeowners, builders, developers, contractors, architects, and city planners, that means getting a complete understanding of what lies beneath the surface—before the first brick is laid.
This includes two essential phases of service. First is the design phase, where the team conducts drilling and soil sampling, delivers detailed foundation recommendations, and assesses for environmental hazards such as methane, radon, and heavy metals. Second is the construction phase, where Marshall Geoscience provides on-site inspection services to ensure that foundations and earthwork meet engineering and safety standards. These inspections are a cornerstone of the company’s work and a key driver of its continued growth.
From hillside homes and multifamily developments to school campuses and high-rises, Marshall Geoscience helps ensure every structure starts with a solid, safe foundation.
Marshall Hayrikian has spent more than 15 years in the field, working his way up from intern to partner before launching his own firm. Based in Los Angeles, Marshall Geoscience now serves the greater LA area, including Orange, Riverside, and San Bernardino counties.
Southern California is one of the most geologically active regions in the country, making geotechnical expertise not just helpful—but essential. That’s where Marshall’s local knowledge and streamlined approach make a difference.
Marshall combines deep technical experience with an emphasis on clear communication and strong project management—two things often missing in traditional engineering firms. Clients appreciate that he simplifies complex concepts, stays involved throughout the process, and helps guide projects from early assessments to city approval.
This customer-first approach is especially valuable when time and budget are on the line. As Marshall puts it, “We’re often the first step in a build, so if we’re delayed, everything is delayed. I make sure we’re responsive, accurate, and proactive.”
Marshall Geoscience is also known for value engineering—analyzing difficult or costly site conditions to find cost-effective, safe solutions. Instead of recommending expensive fixes by default, Marshall uses the latest techniques to optimize project outcomes while saving clients money.
Marshall’s passion for engineering began during college when he unexpectedly landed an internship at a geotechnical firm. What drew him in was the balance of field work and analysis—a mix of geology, civil engineering, and real-world problem-solving.
After a decade of climbing the ranks at his previous firm, Marshall launched his own company with a clear vision: to modernize how geotechnical and environmental engineering are done. Today, he runs Marshall Geoscience with a small, dedicated team and a strong network of collaborators across Southern California.
Marshall Geoscience works with developers, construction companies, architects, school districts, and municipalities. The firm holds on-call contracts with large institutions like the Los Angeles Community College District—the largest community college system in the U.S.—providing ongoing support for both environmental and geotechnical needs.
While many projects are commercial or multi-unit residential builds, the company also supports nonprofits, schools, and community-focused developments—offering discounted rates for select nonprofit projects.
Marshall Geoscience has quickly earned a reputation for precision and integrity—achieving key certifications, launching an in-house soil testing lab, and consistently delivering quality results for complex projects.
Looking ahead, Marshall plans to expand services to offer a more comprehensive package for developers. The goal is to streamline construction workflows by reducing the number of vendors needed for critical pre-construction steps.
Behind every report and soil analysis is a deep commitment to the people and places Marshall serves. Whether it’s a public school project or a hillside home build, the company’s mission is the same: keep structures safe and clients supported.
In a region where the ground is always shifting, Marshall Geoscience offers rock-solid expertise you can count on.
