Pdf Summary

The document outlines a series of webinars focused on the use of nondestructive testing (NDT) methods for evaluating structural concrete, sponsored by the American Concrete Institute (ACI). These webinars delve into critical techniques for assessing and assuring the quality of concrete structures, both newly built and existing ones. The sessions provide insights into methodologies such as Ultrasonic Pulse Velocity (UPV), Ground-Penetrating Radar (GPR), and Impact-Echo (IE) for diagnosing various structural attributes, including thickness metrics, reinforcement mapping, and internal flaw detection.<br /><br />The sessions, conducted by experts like Nate Rende from Wiss, Janney, Elstner Associates, cover the theory, practical applications, and limitations of various NDT methods. Key learning objectives include understanding how to select appropriate testing methods, conducting effective data presentations, and being aware of calibration processes necessary for reliable results. The webinars promise to offer attendees the opportunity to gain Professional Development Hours (PDH) or Continuing Education Units (CEU) upon completion.<br /><br />Case studies within the webinars illustrate NDT applications across different structural challenges, from bridge assessments to detection of construction flaws in masonry walls. The use of various NDT methods is emphasized as they relate to tasks like structural evaluations, corrosion assessments, and condition assessments — all critical for ensuring the structural integrity and safety of concrete constructions.<br /><br />The presentations also cover guidance on NDT best practices, including trial testing, data verification, result calibration, and responsible reporting of findings. ACI and other international organizations provide references for further study and certification programs for practitioners, enhancing their competence in using NDT methods for structural evaluations. Upcoming ACI webinars on related topics are promoted as well, providing a broader context for continued professional development in this field.
