In municipal rights-of-way and dense urban corridors, undocumented utilities represent the single largest financial and safety hazard in telecommunication and civil construction. At Netza Technologies, our Subsurface Utility Engineering (SUE) practice is built to eliminate that risk.
The Four Quality Levels of Subsurface Engineering
Adhering to ASCE and CSA standards, our team systematically categorizes underground utility certainty:
- Quality Level D: Comprehensive record research and historical utility compilation.
- Quality Level C: Surface georeferencing of existing utility features (manholes, valve boxes, pedestals).
- Quality Level B: Two-dimensional horizontal surface geophysical location (electromagnetic locators, Ground Penetrating Radar).
- Quality Level A: Precise three-dimensional verification through non-destructive vacuum excavation (daylighting).
By producing conflict matrices prior to construction bidding, Netza enables carriers to design drill profiles that avoid hydro, gas, and water lines with complete confidence.
