Most critical structural errors occur early—often within the first 30% of construction—when design intent is translated into physical reality. At this stage, small deviations in alignment, sequencing, or force application can significantly influence stresses, geometry, and long-term performance. These issues are rarely visible and tend to compound as construction progresses, making them difficult and expensive to address later. Introducing Structural Health Monitoring (SHM) during construction transforms it from passive observation into an active feedback system, enabling teams to track behavior in real time and make timely corrections before deviations become permanent.
