Abstract:In the last decade, the Indiana Department of Transportation (INDOT) increased the number of construction projects funded by capital made available through the leasing of the Indiana Toll Road. However, during the same time period, the level of personnel available for construction inspection either remained the same or declined. Insufficiency of inspection resources could lead to reduction in inspection and, thus, increased occurrence of potential risk consequences such as short- and long-term functional failures (Figure 1), reduced design life, increased maintenance costs, and reduced safety. The objective of this study was to (1) evaluate the current inspection practices of INDOT and (2) develop a risk-based inspection protocol to facilitate efficient allocation of available inspection resources to minimize the risks associated with reduced inspection.
