Milestones

    • Olson Engineering developed the first PC-based digital Crosshole Sonic Logging system in 1986 - 1987, which was commercialized in 1993. This was followed by the opening of Olson Instruments in 1995.
    • In 1993, Larry Olson was the principal investigator on an USDA Phase I SBIR grant for stress-wave scanning of wood.
    • Between 1993 and 2002, Larry Olson served as the principal investigator on Phases 1 and 2 of an NCHRP 21-05 (2) research grant for the Determination of Unknown Bridge Foundations in June, 2001 and submitted the final report on an FHWA study for dynamic evaluation of bridge substructures in 2002.
    • In 1995, Larry Olson was the principal investigator in a Phase I NSF Ultrasonic Tomography study for concrete flaw imaging.
    • In the 1990’s, Olson Engineering performed historic preservation studies of the concrete substructure and marble on the Lincoln and Jefferson Memorials as well as vibration damage mitigation and corrosion evaluation studies at the Jefferson Memorial.
    • Between 1997 and 1998, Olson Engineering performed a construction quality audit of the embankments, bridge foundations and tunnel linings on a Korean High Speed Rail line from Seoul to Taejon, South Korea.
    • In 2002, Olson Instruments worked together with the Supreme Council of the Antiquities of the Egyptian Government, National Geographic and iRobot Inc. to explore the Queen's Chamber in the Cheops Pyramid in Cairo, Egypt, using the Olson Instruments Impact Echo (IE) head.
    • Larry Olson served between 2005 and 2009 as a co-PI on 2 NCHRP IDEA grants for stress wave scanning of bridge decks and for post-tensioned bridge ducts to check for void.
    • Larry Olson was the Principal Engineer for the Pilot Technology Transfer Project in a Joint Venture of Olson Engineering and Ultra Technologies in New Delhi, India for Northern Railways of Indian National Railways. This project involved the classroom training of 28 civil engineers from 13 railways across India on structural condition assessment of railway bridge piers and abutments. A total of 6 concrete and masonry bridges were nondestructively tested and evaluated with 9 NDT&E methods in March, 2006 in the New Delhi area. Detailed reports were submitted on each of the 6 bridges tested.
    • Between 2006 and 2007 Olson Engineering tested Interstate  90  Indiana  Toll  Road  near  Gary,  Indiana  for  structural  condition assessment  of foundations, piers and abutments, beams and girders, and decks of 8 steel/reinforced concrete bridges.  Olson provided consultation services on steel and concrete repair designs for corroded decks, girders, beams, piers and abutments.
    • Between 2018 and 2019, Olson Engineering has been the subject matter expert for the SHRP2 R06A (Nondestructive Testing for Concrete Bridge Decks) and R06G (Nondestructive Testing for Tunnel Linings) as well as R01B (Utility Investigation Technologies).
