Insight designates the existence and approximate horizontal location of buried utilities in compliance with CI/ASCE 38-02 Standard Guideline 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 


Ground Penetrating Radar 

GPR is a beneficial tool used to help locate utilities that are considered non locatable. Our units have dual frequency antenna assisting in locating and imaging simultaneously deep and shallow utilities/objects, requiring less time on site.  

  • Multiple crews providing immediate availability
  • Imaging of utilities 19’ deep in certain soil conditions
  • Locating underground utilities made of plastic, terra cotta and other non-metallic materials
  • Detecting underground storage tanks, construction debris, depth of bedrock and water table, paving thickness and geologic features

Utility Mapping

Utility mapping can be divided into 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 service you require. 

  • Field run surveys providing precise horizontal and vertical locations of underground utilities
  • Performed to ASCE/CI 38-02 specifications

Insight has developed one of the largest fleets of utility locating units equipped with the most advanced technology in the Washington DC Area.  Our fleet includes high performance air and water vacuum excavation units and field equipment to meet the unique utility locating needs of our clients.   

Our vacuum excavation units perform test holes, exposing buried utilities identifying precise horizontal and vertical location as well as utility material. Test holes are performed creating the minimum exposure necessary as well as reducing restoration efforts post excavation. 

Utility Locating provides: 

  • Depth of utility/utilities
  • Exact horizontal and vertical location
  • Utility material
  • Pipe diameter
  • Width and depth of duct banks
  • Depth of road surface

Vacuum Excavation

Vacuum excavation is the non destructive method of exposing buried utilities to obtain their precise horizontal and vertical location as well their material. Vacuum excavation is performed using air or water and is considered a best practice for safely finding and exposing underground utilities, reducing by more than half the chance of utility damage.
