One of the first steps in any highway design project should be the accurate depiction of the existing utilities. Subsurface Utility Engineering (SUE) has been developed over the past 10-20 years to address this type of utility related issue. The American Society of Civil Engineers, in consultation with the engineering community, recently published a guideline CI/ASCE 38-02, which acknowledges SUE and sets forth the basis for the use of various techniques. Since it's inception around 2002, SUE and the CI/ASCE Standard 38-02 have been used successfully on over 140 projects in Ontario.The authors will analyze how project specific conditions warranted the need for SUE investigations in order to enhance the utility coordination and relocation processes. The paper will discuss the processes used to gather utility information based on each project's specific conditions. The paper will also outline the discrepancies in utility locations that were identified by using this process that would not have been identified using the traditional utility investigation processes. For the covering abstract of the conference see ITRD number E211521.
