Breakwater Survey at Gordon’s Landing

McKim & Creed combined hydrographic surveying, conventional surveying and UAS for a breakwater survey  to ascertain the condition of a rock and stone breakwater at the Gordon’s Landing ferry landing. The breakwater protects the dock from turbulent sea conditions. The Corps needed the survey to prepare plans and specifications for rehabilitation.

McKim & Creed established control and painted stations at 50-ft intervals for future surveys. We collected cross-section measurements at each station every five feet from the center line to 50 feet beyond the toe of the breakwater. Since the breakwater ran both underwater and above the water, we utilized our land, air and sea resources and multiple technologies, including GPS, multibeam, side scan sonar and UAS.
