Every structure around the world has one thing in common: they are built on a foundation of rock and soil. Unfortunately, the physical properties of these materials are as varied as the structures upon them. This variability has long forced geotechnical engineers to rely on instinct and experience when determining the most cost-effective safe solution. Since safety cannot be sacrificed, the margin of error must be covered with more robust and costly solutions than necessary in every case. In an industry where the consequences of error range from costly to catastrophic, Terracon is on a mission to replace educated guestimates with measurable, repeatable data. In this episode of We Measure the World, we talk to Arash Hosseini, Ph.D., P.E. and Matthew Ridgway, P.E. of Terracon about what it takes to make site-specific measurements consistent, accurate, and scalable.
