CGA Released 2018 DIRT Report

On September 26, CGA released the latest DIRT Report. The report is published annually and is based on data entered into the Damage Information Reporting Tool (DIRT) for a given year. 


Highlights from the 2018 DIRT Report include:

  • A refined statistical modeling process estimated that 509,000 excavation-related damages to underground facilities occurred in 2018, compared to the 2017 estimate of 439,000 damages. 
  • Damages per 1,000 one call center transmissions increased slightly from 2017 to 2018, along with a similarly small increase in damages per million dollars of construction spending.
  • Despite these increases, the past 15 years have featured mostly year-over-year decreases in estimated damages since the first DIRT Report in 2004. 
  • The top reported root cause category was “excavation issue,” which encompasses a variety of reported process problems.
  • The biggest singular root cause was failure to notify the one call center.
