TRB’s Airport Cooperative Research Program (ACRP) Synthesis 34: Subsurface Utility Engineering Information for Airports examines ways in which information on subsurface utilities is collected, maintained, and used by airports, their consultants, and the U.S. Federal Aviation Administration to help increase the effectiveness of, and enhance safety during, infrastructure development programs at airports.

The report also compares the current state of technology and effective processes from other industry sectors with what airports do today.
