Even with today’s robust geotechnical investigation programs, state-of-the-art tools and historical data, unforeseen and varying site conditions commonly have negative impacts on planned construction. Allocating and mitigating these risks can have significant effects on the overall project cost, not to mention personal and professional relationships. This panel session will discuss geotechnical construction risks associated with unforeseen and varying site conditions, including obstructions, using examples from the panelists and audience experiences. The intent is to share current strategies and methods that lead to equitable solutions for all stakeholders of a project.
