Synthesis of Information Related to Highway Problems. Topic 46-04.The Impact of Geotechnical Investigation Scope on Construction Claims, Change Orders and Overruns

Construction claims and change orders due to unanticipated or varying subsurface conditions are common causes of project cost escalations. The extent, type, and quality of information obtained from subsurface exploration and testing programs for both design and construction is a significant consideration in minimizing and avoiding these project risks. The purpose of this synthesis is to document the extent and type of claims, change orders, and overruns related to the scope of the geotechnical investigation in highway construction. The synthesis will explore measures taken by transportation agencies to minimize and mitigate escalation of project costs as related to geotechnical investigation for design. Results will help practitioners make informed decisions in managing risks with the use of geotechnical information.
