Toward Rational Design of Void Forms for Expansive Texas Clay Soils: Why do you Still Specify and use Non-Engineered Void Forms for Texas Data Centers?
Engineers have not established a rational design method for void forms, while each manufacturer has developed its own void form products based solely on its proprietary empirical approach. However, none of those empirical approaches have ever been verified with systematic testing or comprehensive analysis by a third party. Simply put, all void form products currently […]
Transforming a High-Risk River Crossing into Design Certainty: Geotechnical Investigation for the US-51 Ohio River Bridge
A comprehensive overwater geotechnical investigation was performed to support replacement of the US 51 Ohio River Bridge between Wickliffe, Kentucky, and Cairo, Illinois. Prior investigations were constrained by complex subsurface conditions, challenging river environment, and platform limitations, resulting in uncertainty for deep foundation design. This study presents an integrated approach to acquiring high-quality subsurface data […]
Long-Term Geotechnical Liabilities Caused by Elevated Groundwater Levels After Construction
Geotechnical reports by all engineers always include groundwater conditions existing at the time of the site and investigation. The reports also indicate the probability of groundwater fluctuation at the time of construction. However, most reports don’t identify the risk of serious structural issues that can develop after construction due to sustained elevated groundwater levels over […]
