Many transportation agencies are building new facilities and rebuilding aging infrastructure with improved project risk reduction and system resilience. Geotechnical site variability is recognized as a significant driver of overall project risk, including cost, schedule, and safety impacts. TRB hosted a webinar on Thursday, February 22, 2024 from 1:00 PM to 2:30 PM Eastern that discussed the evaluation and mitigation of geotechnical risk as a crucial aspect of a successful construction project. Presenters highlighted risk management methods prescribed in existing Federal Highway Administration design guidelines and compare risk management practices. Presenters also shared a case history on a successful application in a recent accelerated bridge construction (ABC) project.
This webinar was sponsored by TRB’s Standing Technical Committee on Soil and Rock Properties and Site Characterization.
The slides are available. Please contact trbwebinar@nas.edu for a link to the recording. There may be a $90 fee.

Learning Objectives
At the end of this webinar, participants will be able to:

• Implement available guidelines on how to optimize exploration plans, resulting in lower risks to designer, owners, and contractors
• Identify geotechnical risks and either document risk mitigation or quantify the risk for the contractor
• Understand how to characterize risks in geotechnical design and construction for ABC and on alternate contract delivery projects
