Influence of Geotechnical Investigation and Subsurface Conditions on Claims, Change Orders, and Overruns

Subsurface conditions are frequently considered to represent significant elements of technical and financial risk for highway construction projects. Unfortunately, information quantifying these risks is rare. This report documents the extent and type of claims, change orders, and cost overruns from subsurface conditions for state departments of transportation (DOTs). Information used in this study was gathered through a literature review and a survey of state DOTs. Follow-up interviews with agencies that have experience with reducing claims, change orders, and cost overruns from subsurface conditions provided additional information. The Synthesis addresses: the scope of subsurface investigation required by transportation agencies; causes of claims, change orders, and cost overruns attributed to subsurface conditions; ranges of costs and prevalence of claims, change orders, and cost overruns attributed to subsurface conditions; and successful practices to reduce claims, change orders, and cost overruns.
