What G2 Consulting Group does
G2 Consulting Group is a Troy, Michigan-based civil engineering firm founded in 1994 that provides geotechnical, environmental, and construction engineering services to public agencies and private enterprises. The firm operates from five offices across Michigan (Troy headquarters, Ann Arbor, Flint, Traverse City) and Chicago, employing approximately 140 people and executing more than 2,500 projects per year. It holds AASHTO laboratory accreditation, maintains in-house drilling capabilities, and is certified to provide services in 35+ states, enabling it to self-perform the full subsurface investigation, materials testing, and construction observation stack.
G2's client base spans state and municipal transportation agencies (notably the Michigan Department of Transportation), large industrial and technology firms (Amazon, Verizon, Fiat Chrysler, Magna), utilities and municipalities (Detroit Water and Sewer, City of Warren, City of Novi), and institutional customers (University of Michigan Health). Its business model is project-based, with revenue generated from as-needed engineering contracts, public-infrastructure pursuits, and private development engagements. Notable project scopes include subconsultant geotechnical work on multi-hundred-million-dollar Amazon and MDOT developments.
The firm has pursued growth through a combination of organic expansion and selective M&A, including the 2015 acquisition of Schleede-Hampton Associates and the January 2026 acquisition of Construction Testing Services (CTS). In December 2023, G2 received a strategic investment from The Great River Company to fund continued geographic and capability expansion. The company has also extended into the renewable energy infrastructure vertical through a dedicated Solar Department and has invested in leadership depth, promoting three professionals to Managing Principal in April 2026.
