Definition
Non-Destructive Testing (NDT) encompasses a variety of scientific testing methods—such as Rebound Hammers, Ultrasonic Pulse Velocity (UPV), and Ground Penetrating Radar—used by structural auditors to assess the hidden, internal integrity of hardened concrete or steel welds without drilling cores or breaking the structure apart.
Practical Example
A consultant suspects that the concrete poured in a main column a month ago failed to reach its target M40 strength. Instead of dangerously drilling a core out of the load-bearing column, they deploy an Ultrasonic Pulse Velocity (UPV) NDT test. The machine sends sound waves through the concrete; the speed of the waves reveals hidden honeycombing and confirms the concrete is too weak.
Application in Superwise
In the event of a quality dispute, QA/QC engineers upload the external NDT laboratory reports directly into Superwise’s Quality module against the specific column's ID. If the NDT determines the concrete is dangerously weak, Superwise workflows automatically trigger a structural demolition and financial penalty sequence against the subcontractor.
