AAE’s approach to foundation investigations is more robust than a simple series of strikes where the user relies on a computer to provide the correct answer in an instant. AAE engineers first verify the foundation type (drilled shaft, pad & pier, pile cap, mat-at-grade, etc.) and lateral geometry through a variety of investigation methods depending on the site conditions we identify. We then utilize a manual approach to the review of the impact-echo data to ensure that the feature we present as the overall depth or thickness of a foundation is consistent throughout data sets. Review of multiple data sets manually also allows us to identify damage, such as soil intrusion in drilled shaft foundations. Finally, AAE employees a dispersive wave test method for below-grade pads/footings that eliminates the need to excavate the footing and measure its thickness directly. This method is extremely valuable in crowded tower compounds, substations, and more.

Yes, we can both determine belled caisson depth and create a relative profile of the shape of the bell to determine if the bell shape is intact or if the bell was partially collapsed during the construction process.

Yes, we have two different approaches to this problem depending on the configuration present at the site.
