Go beyond EM pipe and cable locators with LMX200 GPR

  2. 2. Copyright Sensors & Software Inc. 2018 Limitations of EM pipe & cable locators • Only detects metallic targets or utilities with installed tracer wires • Requires a direct connect or induced current • Locates a single utility in one scan • Accuracy can be compromised when utilities are closely spaced due to “bleeding” of the signal
  3. 3. Copyright Sensors & Software Inc. 2018 When you just use EM … you may miss something & cause damage • 23% of reported damages in the US are caused by insufficient locating practices 56% 23% 16% 1% 4% Cause of Damage Excavation Practice Not Sufficient Locating Practices Not Sufficient Notification NOT Made Notification Practices Not Sufficient Miscellaneous Cause Source: Damage Information Reporting Tool (DIRT) Report for 2016, Common Ground Alliance
  4. 4. Copyright Sensors & Software Inc. 2018 When you just use EM … you may miss something & cause damage • Telecom and Natural gas represent 80% of damaged facilities Source: Damage Information Reporting Tool (DIRT) Report for 2016, Common Ground Alliance
  5. 5. Copyright Sensors & Software Inc. 2018 GPR complements EM technology GPR detects traditionally non- locatable subsurface features including • Metallic & non-metallic pipes – PVC – asbestos cement – concrete storm and sewer systems • Utilities with broken or damaged tracer wires • Underground storage tanks • Drainage tiles • Non-utility structures – Vaults – Foundation walls – Concrete pads
  6. 6. Copyright Sensors & Software Inc. 2018 Additional advantages of GPR • Can delineate close proximity utilities • Provides reliable depth detection • Allows for data visualization to better map the subsurface • Facilitates reporting and archiving of results for future reference
  7. 7. Copyright Sensors & Software Inc. 2018 Example: Using GPR to find non-metallic utilities • A horizontal directional drilling crew accidentally struck a concrete storm sewer that had been missed by locators when installing conduit for fiber.
  8. 8. Copyright Sensors & Software Inc. 2018 Example: Using GPR to find non-metallic utilities GPR effectively pin-pointed the location of the sewer to prevent another expensive fix.
  9. 9. Copyright Sensors & Software Inc. 2018 Example: Using GPR to find non-metallic utilities GPR effectively pin-pointed the location of the sewer to prevent another expensive fix.

  11. 11. Copyright Sensors & Software Inc. 2018 Example: GPR locates utilities in a busy intersection A busy intersection needed to be excavated. The number of utilities made it difficult to get accurate readings from EM locators because of bleed off. GPR was used to collect a grid and map all utilities. It took less than 3 hours to collect the data & get results on-site.
  12. 12. Copyright Sensors & Software Inc. 2018 Example: GPR locates utilities in a busy intersection GPR mapped all utilities, metallic and non-metallic in the intersection, allowing for safe excavation.
  13. 13. Copyright Sensors & Software Inc. 2018 Example: GPR locates utilities in a busy intersection GPR mapped all utilities, metallic and non-metallic in the intersection, allowing for safe excavation.
  14. 14. Copyright Sensors & Software Inc. 2018 Example: GPR locates utilities in a busy intersection GPR mapped all utilities, metallic and non-metallic in the intersection, allowing for safe excavation.

  16. 16. Copyright Sensors & Software Inc. 2018 Example: Locating Underground Storage Tanks • A gas station wanted to install additional monitoring wells but did not have records of the exact perimeter of the underground fuel storage tanks. • They used GPR to map the tanks and other buried infrastructure to ensure safe installation.
  17. 17. Copyright Sensors & Software Inc. 2018 Example: Locating Underground Storage Tanks GPR successfully mapped the location and depth of underground storage tanks and feed lines.
  18. 18. Copyright Sensors & Software Inc. 2018 Use GPR to make Informed Decisions • Confirm that you have located all buried infrastructure • Identify where it is safe to excavate • Document results for future reference • Expand your locating service offerings and make more money • Reduce liability and risk with more thorough locates VALUE INFORMATION Subsurface Data Interpretation Knowledge Informed Decisions
  19. 19. Copyright Sensors & Software Inc. 2018 Add GPR to your locates • GPR gives real-time results • GPR is cost-effective • GPR is easy to learn
  20. 20. Copyright Sensors & Software Inc. 2018 Training Provided by Sensors & Software • Customized training at your facility • Regular courses at Sensors & Software • Online training videos for LMX100 & LMX200 operation • Personalized webinars
