Indiana Department of Transport regularly uses Subsurface Utility Engineering to identify and coordinate utility impacts and relocations to avoid utility delays that risk schedule demands.
Examples of this practice are the I-70 Fast Track and Super 70 projects in Indianapolis, and the I-74 roadway improvements for a new Honda plant in Greensburg.
The INDOT I-70 Fast Track project involved reconstructions to accommodate the expansion of the Indianapolis Airport, and included the relocation and the lowering of a 2.3-mile section of interstate I-70 by 20 foot.
To meet tight scheduling demands, test holes and utility designations were made within the first month.
In addition, proactive utility coordination efforts were initiated to support the aggressive fast-track schedule.
The project was completed with minimal utility disturbances related issues.
