Abstract:In recent decades, state transportation authorities (STAs) such as the Georgia Department of Transportation (GDOT) have increasingly relied upon alternative contracting methods (ACMs) to deliver complex surface transportation infrastructure projects. ACM delivery allocates greater levels of responsibility to the private sector for the completion of engineering design, and by extension, greater levels of risk. This study examines two categories of risk agreed by public and private industry to be of significant import: geotechnical risks and utilities risks. The study utilizes a mixed-methods approach featuring (1) content analysis of contractual and programmatic STA documentation and (2) semistructured interviews with subject matter experts across a broad cross section of the national project delivery network. Synthesizing these results, the study presents commonly identified challenges related to the identification, allocation, mitigation and management of utilities and geotechnical risks in ACM contexts. It furthermore identifies the best practices and strategies utilized across STAs and ACM project networks to address those challenges. The study thereby contributes a highly contextualized integration of contractual analysis supplemented with practitioner perspective. The results offer guidance to GDOT as it seeks to effectively manage utilities and geotechnical risks while fostering a competitive procurement environment.
