Abstract:Stormwater pipe systems are integral features of transportation construction projects. Pipe culverts
direct stormwater away from roadway structures and towards designated discharge areas. The improper
installation of a pipe culvert can result in costly repairs, timely delays, and/or hazardous system failure.
The Florida Department of Transportation (FDOT) has firm requirements for the proper installation and
final inspection of pipe culvert systems. However, there exist problems with the consistent and
accurate use of laser profiling equipment, and there is no standardized testing procedure for equipment
operators. With the goal of developing a certifiable exam, two preliminary exams were produced to
demonstrate operator knowledge of installation and inspection procedures and operator proficiency in
equipment use. The exam was required to consist of a written portion based on the latest FDOT
Specification on post-installation pipe culvert inspection, as well as a field course comprising a pipe run
with known defects to be located and measured. With the intent to aid in the establishment of a
standardized testing procedure and training program, this project took the initial steps in validating
equipment use and operator knowledge and further educating those receiving and interpreting laser
profiling output data.
