Industry professionals gathered at the Back Bay Conference Center to network and enjoy dinner while learning about the Geotechnical Considerations in the Design and construction of Interstate 405 using CPT Data as well as artificial intelligence for Geoprofessionals and how the I-405 data was used to understand further the geotechnical profiles at the bridge locations of the 405 widening.
The presentations were started off by Dr. Amiri, who has over 39 years of geotechnical engineering practice in Southern California and joined the California Department of Transportation in 1991 from the private industry. As a senior transportation engineer (specialist) Dr. Amiri summarized the geotechnical design of bridge foundations for the $2 billion mega-project in Orange County and showcased the transformative potential of Cone Penetration Testing (CPT), marking its first use at this scale in a transportation infrastructure project in California. Dr. Amiri explained how this design-build project leveraged CPT to optimize foundation design, enhance project delivery efficiency, promote sustainability, and implement innovative solutions tailored to the complexities of design-build delivery. This presentation also explored the multidimensional value of CPT, emphasizing its role in advancing geotechnical engineering practices. Lastly, Dr. Amiri informed the crowd that this data has been uploaded to GeoDOG, which is a digital archive of geotechnical data compiled by Caltrans and available for public use. Access to this can be found at https://geodog.dot.ca.gov/.
The conversation continued with Dr. Machairas, a professional and educator with over 10 years of experience in modern data management, predictive analytics (AI/ML), and software development. Dr. Machairas began by providing a brief overview of the latest developments in A.I. and highlighting key opportunities for the use of A.I., particularly for geotechnical engineering practitioners. Dr. Machairas highlighted and described how the $2 billion mega-project in Orange County, which Dr. Amiri previously discussed, offered a wealth of high-quality subsurface and engineering design data that served as a foundation for experimentation with Generative A.I. From advanced information retrieval and synthesis to A.I. agents aiding decision support and data analysis, this presentation demonstrated practical examples of how modern A.I. tools and frameworks can enhance the planning and execution of projects, regardless of their scale.
