| PDF: Based on concerns shared with the Office of the Special Inspector General for Afghanistan Reconstruction (SIGAR) by the military, we have identified potentially significant contract fraud in the installation and inspection of culvert denial systems designed to prevent access to roadway culverts by insurgents. Through our preliminary investigative work, we estimate that a large number of culvert denial systems might have been falsely reported by Afghan contractors as complete when, in fact, the denial systems were not installed or were installed in a defective manner, rendering them ineffective and susceptible to compromise by insurgents seeking to emplace IEDs. |
