What is Subsurface Utility Engineering (SUE)?
SUE is a process to identify actual subsurface utility locations using a combination of research, geophysical methods, and non-destructive excavation/exploration. Typically it involves development of a subsurface utility map for a proposed construction site. It provides the designer and contractor with a much higher level of confidence regarding utility locations than might be available by relying on utility company records (which are often outdated and/or unreliable). For many projects, SUE saves the project significant cost and time, because it reduces the chances of unexpected utility encounters during construction. 2. Why does NTH always have a field engineer monitor drilling during geotechnical and environmental investigations? Unlike most of our competitors, NTH provides full time drilling inspectors during all geotechnical and environmental investigations. This ensures that the boreholes are properly logged, samples are properly collected, all necessary information is recorded,
