Working the Dirt: Mining Money from Soil


While geotechnical engineering does involve getting down and dirty in the soil, it's much more complicated than just digging holes. In fact, geotechnical work is more of an art than a science, as there may be multiple solutions to any given problem. The trick is striking the right balance between risk, expense, and time when making geotechnical decisions.

Join returning speaker Rod Johnston for the 2nd session in our Geotechnical Waltz Master Class Series examining field strategies regarding ground exploration, taking soil samples, working dirt for maximum financial return, and compaction of loose, excavated, or disturbed soils, both in specification and practical use.

To start this online training webinar, we’ll examine how geotechs gain an understanding of the ground beneath them through digging test pits and extracting core samples. All this sampling is expensive however, and geotechnical engineers earn their salt by getting enough information without oversampling and wasting money (i.e. hitting the “sweet spot”). Next, we’ll compare and contrast the two compaction standards, Standard and Modified Proctor, in terms of construction cost, schedule, and product performance. We’ll conclude by discussing parcel and lot compaction and how to meet the requirements of compaction tests.

Learning Objectives 
Attendees can expect the discussion and education of the following learning objectives.

  • Examine soil exploration and sample size considerations.
  • Learn how to mine money from dirt.
  • Understand compaction standards beyond the numbers.
  • Explore the best practices for compacting parcels and lots.
