... 35 chapter five CONCLUSIONS Geotechnical risks in infrastructure construction are widely acknowledged to be significant; however, information quanti­ fying the risks is rare and information quantifying the risks in the context of subsurface investigation scope even rarer. This Synthesis reviews the nature of subsurface risks and geotech­ nical investigations for U.S.

... 36 seven agencies. The number of agencies providing such quanti­ tative data was limited because such data are difficult to extract from databases of all claims, change orders, and cost overruns.

... 37 FUTURE RESEARCH This Synthesis presents findings that significantly reduce uncertainty regarding subsurface conditions claims, change orders, and cost overruns, especially at an agency level. It has also identified several challenges, particularly related to recordkeeping and project­level data, which make further reduction in uncertainty difficult.
