Managing geotechnical risk on US design-build transport projects	2014	19	.pdf	application/pdf	9805	359	36	This document moved geotechnical design on federally-funded highway projects away from a set of “conservative factors of safety” and toward modelling uncertainty on a project-specific basis via a statistically determined reliability index. ‘Managing geotechnical risk on US design-build transport’, Australasian Journal of Construction Economics and Building, 14 (1) 1-19 14 Research Instrument DOT Survey Design-builder Interviews Factor Very/High Impact Some/ Slight Impact No Impact Very/High Impact Some/ Slight Impact No Impact Qualifications of the Design- Builder’s geotechnical staff 89% 11% 0% 91% 9% 0% Design-Builder’s past geotechnical project experience 85% 15% 0% 82% 18% 0% Agency interactivity with geotechnical design team during proposal phase 26% 48% 26% 73% 27% 0% Early contractor involvement in geotechnical design 63% 37% 0% 73% 27% 0% Use of geotechnical performance criteria/specifications 67% 19% 15% 64% 36% 0% Level of agency involvement in the geotechnical QA process 37% 56% 7% 55% 45% 0% Use of agency specifications and/or design details 67% 33% 0% 45% 45% 10% Level of detail expressed in the procurement documents 63% 33% 4% 45% 45% 10% Quality management plans 41% 56% 4% 82% 18% 0% Warranty provisions 22% 48% 30% 18% 55% 27% Table 5 Impact on final project quality Comments and Conclusions The study sought to answer research questions on managing pre-award geotechnical risk and mitigating/retiring that risk expeditiously after award.	cache/ajceb-3745.pdf	txt/ajceb-3745.txt
