Prior to excavating, trenching, pole setting, etc. it is advisable to perform a search for buried utilities such as pipelines, electrical cables, etc. Buried utilities may be located using a variety of devices depending on site conditions. Among available options is ground penetrating radar (GPR). In many states it is unlawful to excavate without notification to utility companies.
Submerged utilities are located through the use of side-scan sonar and magnetometer surveys. |
