AboutUs

OUR HISTORY

Gahagan & Bryant Associates, Inc. (GBA) is a unique engineering firm that specializes in providing consulting and engineering services for a variety of projects, including port development, dredged material management, hydrographic surveying, coastal engineering and construction management. The firm was established in 1975 by William G. Gahagan and J. Franklin Bryant, two engineers both of whom had compiled 20 years of field experience with major dredging firms operating throughout the United States, South America and the Middle East.

GBA is an outgrowth of the Gahagan Overseas Construction Company (later the Gahagan Dredging Corporation), which was a leading international contractor from its origin in 1898. In 1952, Gahagan Overseas Construction Company undertook the dredging of the Orinoco River to facilitate access to Venezuelan iron ore. Later, Gahagan Dredging developed and pioneered the use of spider barges and hydraulic unloaders for the placement of runway fill at Kennedy, Newark and Logan international airports and the placement of road base for a portion of I-95 in northern New Jersey. The practical, and cost-effective approach to problem solutions that typify a successful contracting organization continues with the services offered by GBA today.

GBA was founded on the belief that in order to properly design a dredging program, the designing engineers must have “hands-on” field experience in carrying out real world dredging contracting.
