Abstract

In major infrastructure projects, disputes worth millions are often fought over contract clauses, delays, and payment issues. Yet, in many cases, the outcome ultimately depends on one factor: technical evidence. Among the various forms of technical evidence, Non-Destructive Testing (NDT)- particularly Ultrasonic Pulse Velocity (UPV) Testing- has emerged as a powerful tool in determining the quality and integrity of concrete structures. When allegations of defective workmanship, poor concrete quality, or structural deficiencies arise, ultrasonic testing reports can become central to arbitration proceedings.

Abstract

Structural failures are among the most complex challenges in engineering and construction, often resulting in significant safety, financial, and legal consequences. While the visible damage may be apparent, determining the underlying cause and establishing accountability requires far more than a technical inspection. It demands a structured forensic investigation that integrates engineering analysis with contractual interpretation and evidentiary principles. This article explores the essential stages of forensic investigation from a techno-legal perspective, highlighting how technical evidence, Non-Destructive Testing (NDT), root cause analysis, contemporaneous project records, and contractual obligations collectively contribute to establishing causation and liability. It emphasizes that while engineering identifies the mechanism of failure, a comprehensive techno-legal approach transforms technical findings into credible evidence capable of supporting dispute resolution, arbitration, litigation, and informed decision-making. By bridging the disciplines of engineering and law, forensic investigations not only determine why structures fail but also promote accountability, enhance risk management, and contribute to safer and more resilient infrastructure.
