• Abstract:
  To effectively respond to recommendations of the National Transit Safety Board (NTSB), FTA contracted with researchers to assist the transit industry in developing standards and/or recommended practices for tunnel inspection and maintenance, repair/rehabilitation, and emergency egress. This report summarizes current industry maintenance and inspection practices based on data collected and compiled in 2017 and identifies and describes new technologies for groundwater intrusion remedies, inspection tools, and structural health monitoring. A literature review reveals inspection requirements, frequency, techniques, and documentation and tunnel condition rating criteria. The report presents findings based on standard comparisons, guideline assessments, and working group discussions.
