Storm water delivery systems are an integral part of transportation construction projects. Pipe placement is costly and time consuming, and when a system fails, the costs associated with repairing and replacing the system are significantly greater because of the existing infrastructure often built above the pipe. Several state departments of transportation in the U.S. have standard specifications for the inspection of newly-installed pipe, but no Department of Transportation has standardized operator training for laser profiling or closed-circuit television (CCTV) pipe inspection. This is significant because state-of-the-art systems for underground pipe inspection currently utilizes these two technologies. Likewise, standards do not exist for the certification of systems or operators for CCTV, laser profiling, or other technologies. Within this report are the findings of an ongoing project funded by the Florida Department of Transportation. This paper reports on pipe inspection in the U.S., the development of a field test for laser- and CCTV-based inspection systems, and practical exams for prospective operators of certified systems used in the inspection of underground pipe construction.
