Plan view of slab underbelly showing elevation contours overlaid on top of CAD documentation of spray-paint identified deficiencies. This map allows structural engineers to evaluate structural integrity of the slab. Large spalls/corroded reinforcement can lead to reduced stiffness which in turn can cause localized deflections (e.g. see top right corner).
