About Gannett Fleming

Engineering firm Gannett Fleming has waded through water, waste, and sludge for nearly a century. Gannett Fleming operates through more than a dozen subsidiaries that offer a variety of services that range from design/build, construction management, ground testing and soil strengthening, site remediation, structural rehabilitation, electrical and mechanical installation, geophysical mapping and surveying, and 3D visualization. Founded in 1915, Gannett Fleming serves the transportation, water and wastewater, facilities, energy, and environmental industries, working on projects around the world from more than 60 offices across North America and Middle East.


While the firm is heavily involved in traffic and transportation projects, its water and wastewater infrastructure work is perhaps its hallmark. Gannett Fleming has worked on hundreds of treatment plants and pumping stations, in addition to thousands of miles of water and sewer systems. Over the past decade, Gannett Fleming has designed more than 200 new and renovated dams, and has offered its construction management and inspection services for projects with a total construction cost of more than $4 billion.

The company's long list of services has helped it endure dips in the economy. Its 25 lines of business include information technology, transportation, environmental resources, facilities, dams and hydraulics, site development, and construction management services.

Gannett Fleming's design practice, GeoDecisions, develops master plans for highways, railroads, bridges, and airports. It also designs new dams and modifications on those needing repair.

Geographic Reach

Gannett Fleming has more than 60 offices has offices in the US, Canada, Mexico, Qatar, and the United Arab Emirates. It has been involved in infrastructure and community improvement work in more than 65 countries.

Sales and Marketing

Gannett Fleming serves both the private and public sectors on projects throughout the US and abroad. Some of its clients have included JEA, Washington Suburban Sanitary Commission, the City of Baltimore, New Jersey Department of Transportation, Michigan Department of Environmental Quality, the U.S. Army Corps of Engineers, and Chevron.


Gannett Flemming has made a series of office relocations to be closer to its clients and project work in recent years. In 2014, the company relocated its office in Milwaukee, Wisconsin as part of its partnership with Chicago-based MPR Engineering Corp, which specializes in water, wastewater, and water reclamation and reuse services, with the goal of supporting the growing water-related business and research happening in the Midwestern region. That year, it also moved its Michigan operations in Detroit to Ann Arbor, and moved its San Francisco Bay operations in California from Mill Valley to San Bruno.

The company has also enriched its service offerings and broadened its geographic reach over the past few years through strategic acquisitions. In late 2014, Gannett Fleming bought Pennsylvania-based contractor Innovative Engineering, which expanded its electrical engineering, procurement, and turnkey-construction service offerings. In early 2013, the firm purchased Griffin Engineering and Technical Services to extend its reach into a key research region of North Carolina, broaden its HVAC system solution offerings, and move it more into the biotech, pharma, and healthcare markets.

Mergers and Acquisitions

In August 2014, Gannett Fleming acquired electrical design-build contractor Innovative Engineering (doing business as IETC) to expand its electrical engineering, procurement, and turnkey-construction service offerings.

In January 2013, Gannett Fleming acquired Griffin Engineering and Technical Services, which was added to its mechanical and electrical practices group. The purchase expands Gannett Fleming's presence in the Research Triangle region of North Carolina and its testing, adjusting, and balancing of HVAC systems which increases its reach into the biotech, pharmaceutical, and healthcare fields.
