	abstract = "Manholes represent a rather complex structure for assessing its structural condition and &#8220;leakiness&#147; potential. Factors such as the assembly of components with multiple construction materials and exposure mechanisms to rainfall and runoff make computational scoring and I/I quantification logic complicated. Manholes have the potential to be significant sources of extraneous infiltration/inflow (I/I) but it is difficult converting visual inspections into I/I quantification. The American Society of Civil Engineers (ASCE) 2009 publication titled <I>Manhole Inspection and Rehabilitation</I> and other publications were used to develop an analysis tool for assigning infiltration/inflow (I/I) to standard manhole defects and projecting the I/I rates to vary with specific storm event rainfall frequency, intensity, and duration. The tool also adjusts the I/I rates depending the defect&#39;s component location and on which one of four rainfall runoff exposure mechanisms the manhole is exposed; sheet-flow, ponding/tributary limited, ponding/tributary un-limited, and elevated. The tool&#39;s I/I quantification process and development basis improves the engineering integrity of rehabilitation cost effective analysis and prioritization decisions.",
