Contacting Professional Surveyors

Hiring professional surveyors is a critical step in preparing for an underground utility survey. These experts possess the necessary tools and expertise to accurately map out underground utilities. It's advisable to research and select a reputable company with positive reviews and proven experience in the field.

Once you've chosen a surveying company, schedule a consultation to discuss your specific needs and project plans. This initial meeting will help the surveyors tailor their approach to your property's unique requirements.

Gathering Property Information

Before the surveyors arrive, gather any existing documentation related to your property's utilities. This may include previous surveys, utility maps, or construction blueprints. Providing this information to the surveyors can expedite the process and enhance the accuracy of their findings.

Preparing Your Property

Clear any obstacles that might hinder the survey process. Trim overgrown vegetation, remove debris, and ensure easy access to all areas of the property. This preparation not only facilitates smoother surveying but also helps protect your landscaping investments from potential disruption.

If you have pets, consider keeping them indoors or in a secure area during the survey. This ensures the safety of both the surveyors and your animals.

Understanding Utility Markings

After conducting the survey, professionals will mark the ground with colored flags or spray paint to indicate the location of various utilities. Familiarize yourself with these markings:

  • Red: Electric power lines
  • Yellow: Gas, oil, or steam lines
  • Blue: Water lines
  • Green: Sewer or drainage lines
  • Orange: Communication lines (phone or cable)

Reviewing Survey Results

Once the survey is complete, review the results with the survey team. Ask questions if any part of the findings is unclear or if you need further clarification. Understanding these results is essential for planning future projects or maintenance work on your property.

Planning Future Projects

With detailed knowledge of your underground utilities, you can proceed confidently with any planned renovations or landscaping projects. This understanding allows you to avoid utility lines, ensuring safety and compliance with local regulations.

Consider sharing this information with any contractors or landscapers you hire for future projects to ensure they are fully aware of utility locations.

Maintaining Updated Records

Keep a record of your underground utility survey results in a safe place for future reference. Regularly updating these records is advisable, especially if you make significant changes to your property over time. These records can prove invaluable for future homeowners or property managers.

Preparing your property for an underground utility survey is a proactive step in safeguarding your home and ensuring successful project outcomes. By understanding the process and following these guidelines, you can navigate the complexities of underground utilities with confidence.
