Hydrographic Surveys

Hydrographic surveying relates to land-based surveying in much the same way that marine construction relates to land-based construction. Hydrographic surveying requires the same technology, equipment, skill and experienced personnel needed for land-based surveying, but then adds the need for very specialized hydrographic surveying equipment, data logging equipment, software, GPS equipment, and marine craft capable of handling the demands of this specialized field.

Also required is the knowledge and experience to cope with tidal conditions, river currents, adverse environmental conditions, marine safety regulations, and other factors unique to working in marine environments.

Churchill has performed hundreds of hydrographic surveys throughout New Jersey, ranging from small streams requiring hydrographic surveys for bridge designs to major rivers including the Delaware River, the Passaic River, the Hackensack River, and other major waterways such as the Great Egg Harbor Bay.

Our hydrographic surveying crews have performed upstream, below structure and downstream hydrographic / fathometer surveys for such major bridges as:

Pulaski Skyway Bridges over the Passaic and Hackensack Rivers

Betsy Ross Bridge over the Delaware River

Route 37 EB Mathis Bridge over Barnegat Bay

Washington's Crossing Bridge over the Delaware River This is a truly specialized field, and Churchill has developed a record of outstanding hydrographic surveying services over a span of decades.
