Using cutting edge subsurface investigation technologies, Van Note-Harvey Associates helps clients minimize overall risk, cost, and liability for their projects. VNHA works closely with clients to determine investigative needs, given project specifics and applicable geological and geophysical conditions on the project site. The end result includes documentation and on-site demarcations of hidden subsurface utilities, features, and obstructions before they conflict with the project design, budget, or schedule. The services provided by in-house personnel include records research, designation, location, mapping, non-destructive concrete inspections, graphical representation, and data management. Our trained technicians and advanced instrumentation identify suspected subsurface geophysical detectable targets.
Technological methods employed may include ground penetrating radar (GPR), electromagnetic (EM) conduction and induction, floor and wall GPR scanning technology, magnetics, and pipe sonding technology. Subsurface Utilities Investigation services can be provided during design engineering, pre-construction, and construction phases. Van Note-Harvey’s cost-effective approach focuses on locating subsurface features in a shorter time, keeping our projects on schedule.
