Webinar: Advanced Non-Destructive Evaluation (NDE) Methods for Structural Concrete Assessment
June 11 @ 12:00 pm - 1:00 pm
Speaker: Dr. Larry Olson
PE, President and Chief Engineer
Olson Engineering, Inc.
About the Topic: NDE is being increasingly used to assess conditions of aging structures and infrastructure such as bridges, buildings and dams as well as forensic evaluation of such concrete problems as honeycomb, void and cracking in new structures. Specific NDE methods to be discussed for these applications include ultrasonic pulse velocity, tomography, radar scanning, impact echo scanning, and surface waves. Also to be discussed is data fusion with photogrammetry to overlay NDE results on surface images. Specific learning objectives include understanding NDE methods for condition assessment of corrosion induced delamination of bridge and parking decks, how to map out rebar with 3-D scanning and analyses with radar, and imaging of internal void/honeycomb in concrete with velocity tomography.
About the Speaker: Larry D. Olson, P.E., is internationally known for his expertise in nondestructive evaluation (NDE) of civil infrastructure including dams, bridges, buildings, foundations, pavements, tunnels, etc. He has 40 years of consulting experience in structural condition assessment and monitoring, materials, pavement, geotechnical, geophysical, and vibration engineering. He holds BS Civil and MS (Geotechnical) Engineering degrees from the University of Texas at Austin which honored him as a distinguished alumnus in 2006. He is a member of ACI Committees 228 Nondestructive Testing, 342 Bridge Evaluation and 309 Consolidation.
