About me
Steve Holliger, CST has become Qk4’s subsurface utility specialist by training to locate underground utilities through electromagnetic induction line tracing, Ground Penetrating Radar (GPR), and non-mechanical vacuum excavation using our UtiliVac air system. His methodical approach to underground detective work is followed by his tenacity to safely expose utility lines for their exact location. Steve’s field crew has full location capability from tracing the lines, vacuum excavation, documentation of the facility, and surveying the precise location to project coordinates.
