A slab is a volume, not a guess at the first bar
Concrete scanning with GPR can show reinforcement layout, embedded services and void indicators. Multiarray acquisition lets us read that as a time-slice — a plan at depth — not a single noisy line.
Aus-OMI uses the same Stream DP workflow we use in the street: dense coverage, tomography, evidence next to the call. Core holes and penetrations get a better brief.
