  • Expose Utilities
  • Backfill with excavated material and place corresponding surface references
  • Provide Client with utility structure, condition, and size as well as elevations and site sketches

Utility Designating

  •  Designate, record, and mark approximate horizontal position (accurate within 12± in) of existing utilites
  • SoftDig® uses multiple geophysical techniques for designation
  • Allows for early, broad-scope decisions in a project
  • Surface marks are made with paint and client is provided with detailed sketches

Concrete Scanning

  • SoftDig® uses a state of the art MALA CX-12 for non-intrusive 2D & 3D Concrete Scanning
  • Can locate Post-Tension Cables, Rebar, Conduits, and other targets (accuracy depends on material type and depth)
  • Can be performed on various surfaces (Floors, Walls, Ceilings, Stairs, Bridges)
  • A must for Saw Cutting & Coring projects
  • Targets can be marked on surface and client is provided with detailed reports & sketches on findings

Ground Penetrating Radar

  • SoftDig® uses state of the art MALA GPR systems for surface designation of utilities
  • A combination of Shallow and Mid depth penetrating antenna’s allow for more accurate results (accuracy depends on soil type and depth)
  • Targets can be marked on surface and client is provided with detailed reports & sketches

CAD & GIS Mapping

  • Accurate plotting of Testhole locations and Utility lines
  • Surveyed in using a Trimble Total Station and Reference Swing Tie’s
  • Deliverable to client in PDF, DWG, DGN & GeoDatabase formats for use in AutoCad, MicroStation, and ArcGIS
