EXPLORE OUR STORY
GLDD was founded on the shores of Lake Michigan in 1890. The company’s early roots centered on the dredging and construction of Chicago’s river lock system and existing shoreline, executing work on major city landmarks. GLDD has since grown its service offering and expanded its reach to a global presence.
SAFETY WITHOUT COMPROMISE
In 2006, GLDD adopted an Incident- and Injury-Free® (IIF®) safety management program that has been integrated into all aspects of the company’s culture. Commitment to the IIF® culture promotes a work environment where employee safety is paramount. GLDD is dedicated to the creation and adoption of worker safety programs.
OUR FEATURED PROJECTS
We maintain harbors and waterways by removing accumulated deposits of material. We restore eroded beaches. We rehabilitate damaged wetlands and other aquatic habitats. We deepen existing harbors or build new ones, sometimes creating new land masses by removing soils from approved offshore borrow areas and placing them where they expand shorelines or create islands.
