Three years after establishing its Ann Arbor office, Troy-based geotechnical engineering services firm G2 Consulting Group is doubling its space here and adding staff.

The geotechnical, geoenvironmental, and construction engineering services firm’s work revolves primarily around testing soil, rock, and groundwater for building projects and developing solutions to the challenges the resulting data may present. G2 will move from a 2,700-square-foot space at 1590 Eisenhower Place to a 7,900-square-foot space at 1350 Eisenhower Place at the end of April.

“We’re at a point in our old office that, even if we wanted to hire another engineer, technician, or scientist, we don’t have a desk or chair to put them in,” says Jason Stoops, the firm’s Ann Arbor office manager. “We talked about whether we wanted to stay the same size and service the clients we’re already working for or try to expand our client base. But if we want to expand, we need staff to do that.”

Stoops says the new location has more space than the Ann Arbor office currently needs. However, the office is expecting to add at least four new staff members and warehouse some equipment on site, allowing Ann Arbor to be more of a full-service engineering firm instead of just a satellite office to the Troy headquarters.

G2 has worked on several major projects since opening in Ann Arbor. The Ann Arbor office’s first big project was the Arbor Hills shopping center on Washtenaw Avenue. The firm has since worked on Bank of Ann Arbor’s headquarters renovation and the downtown Ann Arbor Residence Inn by Marriott.

Although the firm is headquartered just an hour’s drive away, Stoops says G2 has worked hard to engage with the Ann Arbor community. A May open house for the new facility will feature Arbor Brewing Co. beverages and Zingerman’s food.

“We’re trying to create the feel that we’re culturally in step with Ann Arbor,” Stoops says.

Stoops raises the possibility that another three years might bring more exciting news for G2. The firm is currently considering opening another office in Ohio or western Michigan.

“We’re hoping to take the success of our Ann Arbor office to other markets,” Stoops says.
