Construction and Maintenance Fact SheetsSubsurface Utility Engineering: Enhancing Construction ActivitiesMarch 2001 FHWA-IF-01-011 Engineering Process Reduces Utility Conflicts, Delays And CostsSubsurface Utility Engineering (SUE) is an engineering process for accurately identifying the quality of subsurface utility information needed for highway plans, and for acquiring and managing that level of information during the development of a highway project. Although SUE is primarily a preliminary engineering activity, the real benefits come during construction. Properly used, SUE prevents unnecessary utility relocations; eliminates unexpected conflicts with underground utilities; reduces contractor delays, subsequent claims and redesign costs; and enhances safety. Many States Use SUEAll State transportation departments (DOT's) have been introduced to SUE. Many use it routinely in the development of highway projects. Those that are not using it are missing out on substantial time and money savings. The Virginia DOT has been using SUE since 1984 and uses it on all projects. DOT's in Maryland, Delaware, Texas, Georgia, Florida, North Carolina, Arizona, and several other States are also big users. Many other States are beginning to use it. Federal-aid highway funds may be used for SUE at the normal pro rate share for the project. Purdue University Gives SUE High MarksThe Federal Highway Administration (FHWA) commissioned Purdue University to find out how effective SUE is in reducing costs on highway projects. Researchers documented a savings of $4.62 in avoided costs for every $1.00 spent for SUE. Free copies of Purdue's January 2000 report, "Cost Savings on Highway Projects Utilizing Subsurface Utility Engineering" Publication No. FHWA-IF-00-014, may be obtained from FHWA.
Designers Certify Quality Levels Of Utility Information On The PlansThe use of quality levels in the SUE process allows designers to certify on the plans that a certain level of accuracy and comprehensiveness has been provided. Project plans may contain any or all of the following four quality levels:
AGC, ASCE Endorse SUEAt a public meeting on January 16, 1997, the National Transportation Safety Board (NTSB) recommended the Associated General Contractors of America (AGC) "promote the use of subsurface utility engineering among its members to minimize conflicts between construction activities and underground systems." The AGC immediately indicated an intent to comply with this recommendation and has done so. The American Society of Civil Engineers (ASCE) is developing a consensus standard entitled, "Standard Guidelines for the Collection and Depiction of Existing Subsurface Utility Data." This standard is expected to be approved in 2001. Copies may be purchased from the ASCE.
