• Complex Utility and Highway Construction Coordination at the World Trade Center
  Abstract: This paper will address the issues that were encountered to replace, upgrade and maintain the utility systems within the Route 9A Project, damaged after the attacks of September 11th in the busiest utility roadway in New York City. The project included the relocation and construction of major utility infrastructure, most serving the new World Trade Center site, while coordinating with and meeting the needs of adjacent projects and maintaining and rebuilding an eight lane urban boulevard, world class bicycle facility and pedestrian promenade.

• Benefits of Subsurface Utility Engineering Services in Transportation Projects
  Abstract: Subsurface Utility Engineering (SUE) is a useful tool for collecting accurate utility information that can be used to improve transportation project performance. Recently, Texas Department of Transportation (TxDOT) initiated a research project to review the state-of-the-practice in utility investigations and develop best practices for timing and use of utility investigation services in the TxDOT project development process. As part of the project, the research team conducted a thorough evaluation of the potential benefits of SUE services (focusing on QL A and B) in transportation projects. During the evaluation, the research team identified 32 projects that used SUE services, which represented a variety of project classes and geographic locations. The researchers then took a significant effort to mine existing TxDOT data sources and collected a wide range of project data from a number of data systems. Based on several measures of effectiveness and using t-test statistics, the study compared SUE projects against a large group of control projects. The results suggested that SUE services tended to be used for large projects with significant design efforts and complicated utility conditions. When comparing on a per-lane-mile basis, projects with SUE had lower design costs and man-hours, fewer construction delays, and fewer utility-related change orders. The findings provide insights as to when and how SUE services were used in transportation projects, and how SUE services might have improved project performance. The study also provided recommendations that can potentially improve SUE-related data management at state transportation agencies.
