Biography
Ms. Randolph has performed thousands of petrographic and microscopical analyses of concrete and concrete materials, including petrographic examination of hardened concrete, air-void system analysis of hardened concrete and aggregate, and consulting on field and laboratory testing interpretation. Ms. Randolph’s experience in concrete evaluation ranges from building components like flooring, roofs and walls to infrastructure systems such as bridges, wastewater tunnels and treatment plants, pavements, and dams. Ms. Randolph performs examinations to assess the quality and condition of concrete, analyzing strength and setting issues, freeze-thaw and chemical-related deterioration, and debonding and delamination. In addition to her work in materials analysis, Ms. Randolph has experience in expert witness testimony.
