Subsurface Utility Engineering
The highest echelon of subsurface utility engineering combining the most recent & advanced technology with the highest trained professionals in the industry.
Subsurface Utility Engineering (SUE)
Subsurface Utility Engineering is the process of identifying, verifying, and documenting underground utilities before excavation or construction. SUE reduces strike risks, prevents project delays, and provides engineers and construction teams with accurate underground data.
Techniques include ground-penetrating radar (GPR), LiDAR, electromagnetic locating, potholing, and geospatial mapping.
Why McLean?
McLean employs the most advanced SUE technology in the industry — including LiDAR survey systems, Ground Penetrating Radar (GPR), and high-precision geospatial tools. Their Utility Field Technicians are trained at the highest level and use the latest methodology to produce defensible, project-ready SUE data.
With McLean, clients get safer excavations, fewer delays, and more accurate designs, backed by field-proven experts.
