Frequently Asked Questions

Yes, we offer detailed mapping services, including PDF maps, KML/KMZ (Google Earth), Shapefiles and AutoCAD/Civil3D drawings.

While public 811 services mark only publicly-owned utilities up to the property line, private utility locating offers comprehensive coverage, identifying both public and private utilities throughout the entire site. This ensures thorough risk mitigation and accurate planning for construction and excavation projects.

The duration of an underground utility locating project can vary depending on the project’s size, the complexity of the area, and the number of utilities to be located. Our team works efficiently to minimize disruptions and complete the project as swiftly as possible, often within a few days to a week for standard projects.

Absolutely. Our non-invasive locating techniques, such as electromagnetic locating and ground penetrating radar, are environmentally safe. For projects requiring potholing, we use vacuum excavation, which is a gentle method that minimizes soil disturbance and potential harm to the environment.

We specialize in locating a wide range of utility types, including electrical and telecommunication lines, gas pipelines, water and sewage lines, and more. While our technology allows us to detect both metallic and non-metallic utilities, certain site and soil conditions or utility types may prevent / obscure the investigation. This is when we recommend potholing to safely expose the utility for visual verification.

While our equipment and techniques allow us to locate a broad spectrum of underground utilities, there may be limitations when it comes to utilities that are non-conductive and do not have a tracer wire, such as certain types of plastic pipes without metallic components. In such cases, we may recommend alternative strategies to ensure a comprehensive utility investigation.

Following the completion of utility locating where we mark your site with paint on the ground, we can optionally provide you with detailed documentation, including maps and photographs, of all identified utilities. This documentation aids in planning your construction or excavation project, ensuring you can proceed with confidence and avoid any potential conflicts with existing utilities.

No problem. Our team can utilize our advanced locating equipment and softwares to create an initial map of existing utilities. This map can then be refined and expanded as more detailed information is obtained through further investigation and locating techniques.

Although not “survey grade” (2M is NOT a licensed surveying company) our utility maps and drawings are highly accurate, thanks to our use of precise locating equipment and advanced mapping and error correction softwares, such as Trimble and Autodesk Civil3D. We strive to provide detailed documentation that accurately represents the subsurface utility landscape, aiding in effective planning and design.

No, we are not a licensed surveying firm and therefore do not provide stamped survey maps. However, we are equipped to generate detailed utility maps and documentation for your project. If stamped survey maps are required, we can make recommendations and connect you with trusted licensed surveying partners to meet your project’s needs.

While we do not stamp SUE maps ourselves, we collaborate closely with a number of Civil Engineering companies, providing them with the necessary utility investigation documentation. This documentation assists their Professional Engineers (P.E.’s) in creating an official stamped S.U.E. map, ensuring that your project meets all regulatory and compliance requirements.
