Why this investigation mattered
Coring through an unknown slab or wall can damage reinforcement, conduits or other embedded systems. The challenge is not only to “see rebar,” but to give the drilling team a practical clearance decision at the exact locations where work is planned.
Structural elements can contain multiple reinforcement layers, varying cover, congested zones and interfaces that produce complex radar responses. Interpretation therefore needs to be tied to the actual coring location and to the limitations of scanning from the accessible face.
Investigation strategy
High-resolution concrete scanning was focused on the proposed coring zones. Survey lines were arranged to recognize repetitive reinforcement patterns and distinguish them from less regular embedded features.
The field output prioritized practical marking and clearance information. Where the scan could not confidently rule out an embedded target, the location was treated conservatively instead of being declared safe by assumption.
