Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

38 Following is a brief questionnaire intended to identify how airports and other organizations collect, store, and use information about subsurface utilities. We will use these questions as a guide during a phone interview. Answers to these questions from a variety of airports will be consolidated to identify industry best practices, technological trends, and opportunities for further research that will benefit airports and utility providers. These findings and recommendations will be published in an Airport Cooperative Research Program synthesis report. The specific information you provide will not be publicly available in a manner that can be associated with you or your airport. Consolidated statistics, which combine results from many airports, will be published in the final report.

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.
