Insight designates the existence and approximate horizontal location of buried utilities in compliance with CI/ASCE 38-02 Standard Guidelines for Depiction of Existing Subsurface Utility Data. This investigation is accomplished by using both active and passive utility detection equipment.

  • Immediate availability, on site usually within one week of Notice to Proceed

  • Large fleet of state of the art equipment

  • GPR units on site, finding utilities considered not identifiable

  • Large scale designating projects accomplished in minimal time

Recent revisions to the DC Water Project Design Manual Volume 3 - Linear Infrastructure Design July 2018 require subsurface utility engineering:

“3.2 SUBSURFACE UTILITY ENGINEERING Utility designations shall be performed during design as described in CI/ASCE 38-02 to identify underground utilities. Unless otherwise stated, the minimum utility survey designation for locations anticipating excavation work shall be Level C. Level A is required when an excavation will be within 12 inches of an existing water or sewer utility. Level B is required for new water and sewer assets that will be located within two (2) feet of other buried utilities. Levels B and A may be required in other site(s) specific circumstances when directed by DC Water. “

Utility Mapping

Utility mapping can be divided into the levels of service required. Utility records research provide approximate utility location, further utility location can be obtained via utility designating and utility locating services.  Our team will listen to your goals, assess your specific needs and provide a plan for the service you require. 

  • Field run surveys providing precise horizontal and vertical locations of underground utilities

  • Performed to CI/ASCE 38-02 specifications

  • Planimetric drawings in an AutoCAD format

Private Utility Marking

Insight has one of the largest fleets of state of the art utility locating equipment in the Washington, DC area providing utility designating and mapping required on sites not covered by the One Call System. Sites include military bases, campus environments, universities, office and industrial complexes.
