When Hawaiian Dredging Construction began, one of its earliest projects involved opening the channel entrance into Pearl Harbor. Since this time, Hawaiian Dredging Construction has provided licensed contracting construction services throughout Hawaii and the surrounding Pacific regions. The company builds housing, hotels and resorts, highways, bridges, power plants and marine projects. It provides design-build, design-assist, construction management services and can carry out rehab and renovation work. Hawaiian Dredging Construction is a Dillingham Company. Since the mid-1960s, Dilligham has provided preconstruction, construction management and built more than 18,000 hotel rooms worldwide. Headquartered in Honolulu, Hawaiian Dredging Construction was founded in 1902.
