February Tucson Chapter Lunch Meeting

Emerging Non-Destructive Evaluation (NDE) Geophysical Technologies

for

Structural Assessments and

Project Risk Reduction

Several emerging geophysical non-destructive evaluation (NDE) methods and technologies are gaining in popularity to reduce the need for expensive and time consuming destructive methods and X-ray evaluations, to reduce structural QA/QC assessment time, and to reduce risk and project costs in evaluations. Southwest Geophysics' project evaluators are using a variety of recent technical advances. This presentation will include discussion of several applications of emerging NDE technologies for structural evaluations:

• Ground penetrating radar (GPR)               
• Ultrasonic pulse velocity (UPV)               
• Impact echo (IE)           
• Impulse Response (IR)               
• Pile integrity testing (PIT)               
• Seismic methods (refraction tomography, MASW, ReMi)           
• Electromagnetics (EM)              
• Electrical resistivity tomography (ERT)                  

Guest Speaker Bio: 

Mark D. Edwards, R.G. (AZ - 52449) Principal Geologist/Geophysicist Southwest Geophysics, Inc.

Mr. Mark D. Edwards has 25 years of extensive national and international experience in geophysical and geologic evaluations, geologic resource evaluations, infrastructure and environmental assessments, hydrogeological evaluations, geologic and geophysical site characterization, environmental remediation, subsurface utility engineering (SUE), forensics, and regulatory Quality Assurance/Quality Control (QA/QC) requirements. A diverse background and wide variety of project experiences allow him to manage geophysical, environmental, and geologic projects. As Principal Geophysicist and Geologist for Southwest Geophysics' Arizona office, Mr. Edwards manages geophysical, geologic, and environmental field evaluations; conducts geophysical evaluations including seismic refraction, downhole and crosshole seismic, MASW seismic, refraction microtremor (ReMi) seismic, ground penetrating radar (GPR), magnetics, electrical resistivity, and electromagnetic (EM) studies; plans and conducts site characterization; performs detailed geologic reconnaissance studies through literature review, field mapping, analysis of aerial imagery; and satellite imagery and data; and performs utility designating. He provides summary geophysical survey reports including data interpretations and findings regarding geologic, structural, and environmental factors.
