| 摘要： | This report presents the results of a study that investigated the challenges and opportunities facing Subsurface Utility Engineering (SUE) in Penn DOT highway projects. The study took an in-depth analysis of ten SUE projects by Penn DOT districts. Based on this analysis, a decision matrix tool to determine which projects should include SUE and the appropriate level of SUE investigation to be used has been developed. A detailed cost-benefit analysis was also performed on these ten SUE projects. All of the projects showed a strong relationship between SUE benefit-cost ratio and buried utility complexity at the project site. The analysis clearly showed that there is no relationship between SUE benefit-cost ratio and project cost and also no relationship between buried utility complexity level and project cost. The conclusion of this research is that SUE quality levels A and B should be used based on the complexity of the buried utilities at the construction site to minimize associated risks and obtain maximum benefits. / Supplementary Notes: Sponsored by Pennsylvania Dept. of Transportation, Harrisburg.
