Hydrographic

 Hydrographic Surveying

lllDennis Corporation staff has personal experience acting as project manager for numerous hydrographic coastal surveys from Wilmington, NC to Jacksonville, FL and many inland specialty projects. Project highlights include the maintenance dredging for the State Ports Authority Georgetown Terminal. The project scope included performing conditional, pre and post dredge surveys for the shipping berths along the terminal docks on a bi-annual basis. The results of the completed survey were then used for quantities to determine the dredging fee.

An average time for the completion of hydrographic survey is one to two weeks from the notice to proceed. All hydrographic surveys are tied to the State Plane coordinate system and the vertical datum.
