Subsurface Utility Engineering

NTBA brings our surveying and engineering capabilities together with our utility locating and designating resources to assist with the management of risks associated with underground utility mapping at any stage of your project. Gathering data from all available sources as well as maintaining good working relationships with state DOT’s, local governments, utility companies, and other engineering/consulting firms allows us to provide clients with the most comprehensive information available. 

NTBA specializes in:

  • Quality Level A: Utility Locating via Test Hole

  • Quality Level B: Utility Designation 

  • Quality Level C: Utility Visible Surface Feature Surveys 

  • Quality Level D: Records Research/ Data Collection

We utilize a combination of civil engineering, surveying, GIS, electromagnetic, ground penetrating radar (GPR), and nondestructive excavation to provide the most accurate information for our clients to help them in making informed and timely decisions. Our SUE professionals operate in accordance with ASCE 38-02 Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data addressing the four different Quality Levels, or any combination thereof, to meet our client’s specific and unique needs. 

Our utility designating and locating group is cross trained with our surveying group allowing us to offer complete turn-key services thereby eliminating the hassle with coordination between multiple contractors. In most cases, our utility crew also surveys the utilities reducing the wait time for data delivery. We can deliver data files in AutoCAD or Microstation format. Our comprehensive SUE services give our clients the opportunity to make informed decisions during the design phase as well as mitigate and manage utility risks on projects to reduce utility conflicts, construction delays, and redesign costs.
