Our History

When Farley Gannett partnered with Theodore Seelye to form Farley Gannett, Consulting Engineer, in Harrisburg, Pennsylvania, on Aug. 1, 1915, they likely never imagined their company would be shaping infrastructure and improving communities around the globe 100 years later – across more than 60 offices and 2,000+ highly qualified employees worldwide.
The Wiscoy Dam near Fillmore, N.Y., 1922 Party of Two
In 1915, Gannett and Seeyle were just a party of two with dreams of helping to advance America’s infrastructure during some of the country’s most exciting times in urban development. Since then, our history has closely paralleled the history of infrastructure systems in the U.S. during the 20th and 21st centuries. Rapid urban growth and the need for mass transportation, safe drinking water, and flood and pollution control were a few of the factors that fueled demand and opportunity for engineering services.
Erie, Pa., flood control conduit, 1918 Early Work to Rich History
Just two short days after opening their doors, Gannett and Seelye’s young company was put to the test in its first major assignment. And it was a somber one. Nearly 300 miles away in Erie, Pennsylvania, a tragic event known as “Erie’s Blackest Day”? occurred when Mill Creek flooded the town, killing 36 people and causing millions of dollars in damage. To prevent future catastrophes, Gannett and Seeyle were called upon to study flood control problems on the creek and later design and construct a large conduit to move excess flows to Lake Erie. Our rich tradition in water resources engineering was born.
A 1929 map of 22 electric utility properties in Buenos Aires, Argentina. An Enterprising Duo
Gannett and Seeyle were entrepreneurs of the first order. In the 1920s, they acquired electric and water utilities across the U.S. and began designing and building improvements to these systems. Once a utility was in good working order, it was sold in order to provide funds for the next acquisition. Having perfected this model in the States, electric utilities in South America became part of the portfolio in the late 1920s and early 1930s. We maintained ownership in a number of water utilities until 1955, which paved the way for our entree into valuation and ratemaking for public utilities.
The Hazleton Wastewater Treatment Plant, Hazleton, Pa., 1962 Sustainability from the Start
We’ve always believed in sustainable initiatives that reduce human impact on the environment. As methods of sewage disposal in the U.S. moved away from drainage canals and polluted streams, Gannett Fleming was at the forefront of pollution abatement through the design of wastewater treatment, solid waste disposal, and air pollution control facilities as early as the 1930s.
The Pennsylvania Turnpike Eastern Extension from Carlisle to Philadelphia, 1947 Hitting the Road
As the nation's highway system developed from a few miles of narrow, twisting roads to a vast network of expressways and turnpikes, so grew our highway and bridge capabilities. We designed major portions of the Pennsylvania Turnpike, which set the standard for the tolling industry and became the model for many toll roads that followed. The subsequent development of the interstate highway system in the 1950s and 1960s was a major catalyst for our further growth in the transportation market. Gannett Fleming not only kept pace but became a pioneer of excellence in this area, with some projects hailed among the finest roadways and bridges in the U.S.
The PHX Sky Train at the Phoenix Sky Harbor International Airport, Phoenix, Arizona, 2013 Riding the Rails
In the 1960s, we designed many of the new transit systems being constructed across the U.S., including a portion of the Southern New Jersey Rapid Transit System, the nation’s first high-speed mass transit system. In the early 1990s, we received a major general engineering contract from Amtrak, which led to an ongoing relationship spanning nearly 300 projects. Gaining ground in transit maintenance facility expertise, we designed the Long Island Rail Road’s Holban/Hillside Maintenance Complex, the largest facility of its kind in the country. And with our 1985 design of the Detroit People Mover – the first design-build project in the nation – and more recently, the PHX Sky Train® at Phoenix Sky Harbor International Airport, we now hold a prominent position in the automated people mover market.
Water supply system for the city of Quito, Ecuador, 1962 Water: From Source to Tap
From early concepts through today's cutting-edge methods, we've pioneered the safe and efficient collection, treatment, and distribution of potable water. During our history, we have completed more than 1,000 water supply projects that assist communities in finding new sources of water, maintaining the quality of present sources, treating water for safe consumption, and providing the means to transmit water from source to tap.
The Fort Indiantown Gap Cantonment in Lebanon County, Pa., 1941 Building It Up
Since the earliest days, we’ve designed an array of public and private facilities, including major cantonments and airfields during World War II. Since that time, we have provided diverse, building-focused architectural and engineering design services across a broad array of businesses and industries. Now, we offer a robust facilities division with a wide range of services for facilities projects and includes LEED®-certified professionals and Envision™ Sustainability Professionals who are dedicated to sustainable technologies and systems.
Gannett Fleming employees perform hazardous and solid waste studies at the S-Area Site in Niagara Falls, N.Y., 1983 Restoring the Environment
As environmental awareness took center stage in the 1970s, we developed expertise in assessing and cleaning up thousands of hazardous waste sites. Our practice has grown to include comprehensive site assessments and remediation at thousands of locations throughout the U.S. and abroad. We now provide commercial and industrial clients with innovative, sustainable strategies, such as remediation-focused investigation, real-time plume delineation, monitoring cost reduction, and risk-based cleanups.
Gannett Flemings Transportation Operations Practice employees install a Dynamic Messaging sign along a highway. Technology-Based Decisions
We began using computing equipment to support engineering calculations in 1955, moved to computer-aided design and drafting in the mid-1980s, and evolved to include 3-D building information modeling today. Beyond engineering design, we began using computer-supported management decision making in the early 1990s. And we've developed geographic information systems that guide logistics, traffic incident management, siting of services, and many other applications for the U.S. Department of Defense, state departments of transportation, and insurance companies.
Software developers in Gannett Flemings Abu Dhabi, United Arab Emirates, office collaborate on a geospatial web portal for the Abu Dhabi Urban Planning Council. A Global Perspective
An international demand for expert engineering services opened doors for us around the globe. Since the 1920s, we've completed hundreds of projects in more than 65 countries, with South America as our first international venture. Overseas activity expanded to include assignments in Central America, Europe, the Bahamas, Africa, and Canada. Today, we maintain international offices throughout North America, Qatar, and the United Arab Emirates.
