Inception of the Firm

GEI’s founders all met when they were attending a graduate program for civil engineers at Harvard University. There, the founders were taught by Arthur Casagrande, a professor and pioneer of geotechnical engineering. After graduating from Harvard, Daniel LaGatta presented the idea of starting a consulting firm to his fellow classmates Ronald Hirschfeld, Steve Poulos, and Richard Murdock. At the same time, one of their other classmates Gonzalo Castro, returned from his home in Chile and joined Dan, Dick, Ron and Steve in their efforts to start a consulting firm.

In the summer of 1970, the five opened GEI’s first office in Winchester, Massachusetts.

Birth of GEI's Environmental Practice

As GEI continued its organic growth in Massachusetts and throughout the Northeast in the 1970s and into the 1980s, its founding members explored opportunities to expand the firm’s service offerings by adding specialties related to geotechnical engineering. Regions within Massachusetts were growing at a rapid rate, and soil and ground water contamination was becoming a new business area. GEI’s expertise in soils and ground water provided the firm a solid base to enter this emerging field.

GEI’s environmental practice continues to flourish today, having expanded its capabilities nationally.

GEI Expands Outside of Northeast to Denver, CO

Building on the firm’s successful dam inspection projects and its relationship with the U.S. Army Corps of Engineers, GEI was engaged by the U.S. Bureau of Reclamation (USBR) to complete dam inspections and assessments throughout the west country. Following the catastrophic failure of the Teton Dam in 1976, USBR passed the Reclamation Safety of Dams Act, requiring an extensive safety inspection process for dams determined to pose high and significant hazards to the public. As a direct result of this engagement, GEI opened a Denver, CO office that was in close proximity to the Reclamation’s Dam Safety Office.

To date GEI has completed over a hundred dam inspection projects for USBR, and GEI’s Denver office remains in operation today, having since expanded its service offerings to include environmental and ecological services.

Carlsbad, California Office Opens

As part of GEI’s vision to expand and be recognized as a national engineering firm, GEI had its vision set on the West. When the need for an experienced civil/geotechnical engineer presented itself for the looming San Diego County Water Authority’s (SDCWA) Emergency Carryover and Storage Project, GEI accelerated its efforts to expand into Southern California. The project was recently awarded the Outstanding Civil Engineering Achievement (OCEA) Award in 2017.

Once engaged by SDCWA, GEI’s Thomas Keller relocated from the firm’s Massachusetts headquarters to lead the project and opening of GEI’s first West coast branch, located in Carlsbad, California. From the project’s inception, GEI’s Carlsbad office grew at a rapid rate, and the high-profile nature of the project helped the office continue to grow its client base.

The Emergency Carryover and Storage project was a 24-year engagement with GEI serving as the Owner’s Engineer, and was led for the entirety of the project by Thomas Keller. The project received national recognition from industry professional organizations and publications.

In addition to the success of the Emergency & Carryover Storage Project, GEI’s Carlsbad office thrives today, promoting a culture of partnership and project success that continues to satisfy clients both old and new in the dam and water resources markets.

GEI Expands Environmental Practice with the Acquisition of Atlantic Environmental

GEI’s founders recognized early on the relation between geotechnical expertise and environmental capabilities, which led to their conscious pursuit to try to strengthen their service offerings in these areas. When GEI began partnering with Atlantic Environmental Services, Inc. in the early 1990’s they recognized the shared collaborative nature the two firm’s and their passion for client success. The partnership led to the eventual agreement for GEI to acquire Atlantic in 1997.

When Atlantic joined GEI, the firm’s capabilities and headcount expanded considerably through the addition of 70 employees and a St. Louis office. The acquisition of Atlantic directly led to GEI’s growth in the Manufactured Gas Plants (MGP) market, where Atlantic had been both nationally and internationally recognized for its expertise. This also established GEI’s initial presence in the mid-west.

To date, GEI has been involved in over 600 MGP site investigations, characterizations, risk assessments and feasibility studies for both utility and industrial clients, and has completed more than 100 MGP site remedial designs.
