William G. Gahagan, P.E. passed away on November 14, 2019. Bill was one month shy of his 90th birthday.

Bill Gahagan was a dedicated lifelong pioneer and leader in the dredging industry. An engineer by schooling and trade, Bill’s family started Gahagan Overseas Construction Company (later the Gahagan Dredging Corporation), which was a leading international contractor from its origin in 1898. Gahagan Dredging developed and pioneered the use of spider barges and hydraulic unloaders.

Bill later headed-up Gahagan Dredging where the company was responsible for the dredging of the Apollo Launch Site in Florida, and Newark (NJ), Kennedy (NY), and Logan (Boston) Airports. Gahagan Dredging was known for its innovations in developing equipment and dredging techniques for difficult projects. After a sea change in the industry, Bill became a consultant to Great Lakes Dredge & Dock in 1972.

While working at Gahagan Dredging, Bill met J. Franklin “Frank” Bryant, a veteran of the dredging industry. Frank later started Bryant Engineering and was contacted by Bill in 1974 for a project at Jupiter Island, Florida – a project notable as the first use of a hydraulic cutterhead dredge working in the ocean to renourish a beach. This led to the formation of Gahagan & Bryant Associates, Inc. (GBA) in 1975. It also established a lifelong bond between the two men and a shared belief that to properly design a dredging program, the designing engineers must have “hands-on” field experience in performance of dredging contract work.

Following that philosophy, GBA has grew into the largest firm in the United States specializing in dredging and marine-related projects. Clients soon learned that GBA reports were concise, clear and well-focused. A GBA report states, “this is the issue, this is the solution,” and the solutions work. GBA employees are always encouraged to learn the industry and hone their capabilities in the field, collaborating with owner and contractor.

GBA’s success was initially driven by Bill Gahagan’s ability to provide sound, practical solutions to complicated projects. Once GBA was anchored as an established firm, Bill shifted his focus to mentoring future leaders in the industry. His dedication to the growth and development of engineers is unparalleled, as is his honorable and selfless contribution to the dredging industry. Within GBA and throughout the dredging industry, many executives, engineers, surveyors, and consultants have been positively influenced, inspired, and mentored by Bill Gahagan.

We toll the bell 89-times for Bill Gahagan to mark the end of his final watch — now rest in peace. God Bless.
