EFFC/DFI NDT Guide Task Group
The Non-destructive Testing (NDT) Guide Task Group was formed in 2024. Their goal is to develop a guide that will summarize existing publications, theory behind techniques and when and when not to use the techniques. The guide will also provide guidance on evaluation and acceptance of test results.
Group Co-Chairs
Karsten Beckhaus, Dr.-Ing.
BAUER Spezialtiefbau GmbH
Karsten Beckhaus, Dr.-Ing. is the technical director at Bauer Spezialtiefbau, has more than 30 years in structural engineering, 21 of those in deep foundations, and holds degrees from Technical University in Munich. He leads Bauer’s technical services division, focusing on quality, innovation, and sustainability. Beckhaus chairs European execution standards EN 1536 and EN 1538, shaping the future of foundation engineering.

Non-Destructive Testing Guide
Previous versions of the EFFC/DFI Guide to Tremie Concrete for Deep Foundations addressed non-destructive testing (NDT) in the appendix. With each edition, the appendix expanded to cover more topics. EFFC and DFI recognized that the information contained in the appendix was applicable to more than just tremie concrete for deep foundations and that the existing literature was outdated to current practice and technologies. In addition, no single publication covers the theory, application and evaluation of all methods.
Proposed NDT Guide
The first edition of the proposed NDT Guide will focus on methods used with drilled and excavated deep foundation elements. The guide will summarize the theory, applications and limitations for each method, along with recommendations on evaluating the results. The guide will define “anomaly” and “defect” to provide a basis of understanding in the industry and provide guidance on the process to determine whether to accept or reject a deep foundation element.”
