Optimizing I-69 Route Selection Via Geophysics
EnSafe used non-invasive technology to cost-effectively assist the Tennessee Department of Transportation (TDOT) with the tremendous challenge of siting a freeway through an area with a multitude of issues, both engineering and environmental.
To help TDOT select a route for Interstate 69 — the 1,600-mile, eight-state highway that ultimately will connect Mexico to Canada — EnSafe minimized both construction costs and negative impact to a distressed community by building a comprehensive Geographic Information System database of critical information about the Frayser area in Memphis and an area west of Millington.
Geophysics supplied missing pieces of information crucial to optimal route selection and construction planning. EnSafe accomplished this well in advance of construction, allowing identified problems to be addressed early in the project’s design stage. The actual cost-savings provided by geophysics were 10 times the cost of the services.
EnSafe's work won the Surveying and Mapping Grand Award in American Council of Engineering Companies of Tennessee's 2010 Engineering Excellence competition.
