Cable/Pipeline As-Built Surveys
Combining installation information as well as survey information collected following installation we can provide documentation and drawings of the final true (as opposed to designed) location of power and communication cable and pipeline.
The data collected can be both on shore, collected with standard land survey methods or offshore, collected with sidescan and multibeam sonar. If the cable is buried onshore we own the cable/pipeline location equipment to determine its location. If the cable or pipeline is buried offshore it can often be located with the aid of a cable/pipeline locator, sub bottom profiler or magnetometer.
The collected and drafted information is often used by the project owner for maintenance and permitting requirements.
