Utility mapping is the process of identifying and documenting the location of underground utilities, such as water, gas, electricity, and telecommunications lines. This is crucial for construction and excavation projects to prevent accidental damage to these services, which can lead to costly repairs and safety hazards. The mapping process typically involves using specialized equipment like ground-penetrating radar and electromagnetic locators. Professionals may also refer to existing utility records and collaborate with utility companies to ensure accurate data. Proper utility mapping helps streamline project planning and enhances overall safety in construction sites.
