This presentation focuses on describing low cost methods for assessing the condition of aboveground infrastructure elements such as concrete structures (storage basins, clearwells, filter boxes, water conduits, buildings), steel structural systems (pipe supports, pipe support frames), and aboveground piping. The papers reviews the instruments, techniques, and standards currently used for condition assessment. These include: visual examination, sounding with masonry hammers, pachometers, chloride ion sampling, depth of carbonation, petrographic evaluation, half cell potential, Windsor Probe, pit depth gauges, micrometer measurements, and ultrasonic testing (A and B Scans).
