Subsurface utility engineering standard ASCE 38-02 (2002)
The American Society of Civil Engineers published ASCE 38-02, the first standard assigning quality levels to underground utility location. The rule gave utilities, contractors, and engineers a shared language for how confident they could be about what lies under a job site.
Gave the industry a shared basis for designating and locating buried utilities in design and construction work.
Created a sustained market for ground-penetrating radar and other subsurface sensing tools, which has since converged with satellite positioning.
Explains why contractors want GPR: accurate subsurface data, given precise location, prevents damaged utilities and wasted excavation.
