Patrick Miller

Patrick Miller, P.E. has been with Olson Engineering / Instruments for 18 years, where he has been heavily involved in nondestructive evaluation (NDE) engineering consulting projects on all types of civil structures, applied research including federally funded studies and NDT product development on systems such as the Olson Resonant Tester (RT-1), Sonic Surface Scanner (SSS) and Light Weight Deflectometer (LWD). Mr. Miller has also been involved in client training on all systems that Olson Instruments manufactures, both during in-house seminars and traveling abroad for special projects.

Mr. Miller has managed and conducted nondestructive evaluation (NDE) investigations to determine the conditions of such facilities as concrete and asphalt pavements, concrete bridges (including post-tensioned girders), concrete pipes and tunnels, various concrete slabs (including spillways), various structural elements of buildings, dams, concrete retaining walls, deep foundations as well as geophysical investigations to determine in-situ soil properties. Investigations were performed with a variety of Non-destructive test methods, including: ultrasonic, sonic, seismic, and electromagnetic. Mr. Miller has also conducted condition assessment investigations which have included destructive testing such as extraction of concrete cores for compressive strength, petrography, chloride testing, and carbonation testing to help identify concrete material degradation factors. Mr. Miller has also been involved in material repair recommendations and designs for concrete bridges, abutments, building, and culverts.

Mr. Miller spent 2 ½ years in graduate school at the Colorado School of Mines where he was employed at different times as both a Teaching Assistant and a Research Assistant. As a Teaching Assistant Mr. Miller taught undergraduates in both a Multidisciplinary Engineering Laboratory (MEL) Fluids laboratory course as well as a Soil Mechanics Laboratory Course. As a Research Assistant Mr. Miller designed and built a light weight deflectometer (LWD) similar to commercial devices to determine the in-situ level of compaction of soils, and specifically research newly proposed methods of data analysis. He also utilized a wide array of in-ground sensors to measure the in-situ stress and strain induced by the device. Mr. Miller was also involved in a separate study evaluating the possible use of wireless sensors in slope inclination surveys. While attending Tufts University in pursuit of his Bachelor’s degree Mr. Miller also worked through the summer of 2003 and part time during his senior year (2003/2004) at Axyz, Inc. a firm specializing in forensic engineering and accident reconstruction.
