CONSULTING SERVICES FOR NDT & GEOPHYSICAL INVESTIGATIONS

NONDESTRUCTIVE TESTING & EVALUATION


Olson’s NDT services can test, evaluate, image, measure, and scan almost any type of structural or infrastructure element for the purpose of constructing, maintaining, or retrofitting, and offer options for repair when concerns are identified, allowing the risk to be mitigated. Materials that can be evaluated by nondestructive methods include concrete, masonry, wood, asphalt, stone, and pipes.

Benefits of NDT

  • Complete diagnosis of visible and hidden structural material conditions
  • All operations are performed with minimal or no damage
  • Lower cost and reduced risk for the public, owners, contractors, and engineers.
GEOPHYSICAL SERVICES


Olson’s geophysical imaging services are primarily applied to engineering, environmental and ground water problems helping to determine subsurface conditions that are problematic, anomalous or unpredictable, permitting our clients to better design and minimize risk for construction, site investigation, and drilling.

Benefits of Geophysics

  • Non-invasive approach to image large volumes of earth materials beneath a site
  • One-, two-, and three-dimensional (1D, 2D, or 3D) surveys
  • Uses any existing geotechnical data to calibrate results between, below, and beyond drill holes
