Unknown geotechnical conditions are a major source of risk. Unexplored places vastly outnumber the sampled and tested ones, and widely spaced boreholes with intermittent tests and samples are the norm. Sometimes site-specific planning and thought goes into locating these special, tested places, such as basing them on the geologic understanding or anticipated key locations for the structure; more often they are simply evenly distributed. We demonstrate a holographic model that allows viewers to see real data in real space, scaled or not, and to visualize where measurements are taken, what those values are indicating, and where there exists more unknown and more risk. The holographic model shows in an intuitive way, values from Standard Penetration and Cone Penetration tests, and surface geophysics. The mixed reality of this future is that a wide audience – owners, designers, project managers, contractors, and stakeholders interact together in a real space where they see and talk to each other, while at the same time are individually looking all around below or above ground, like a gopher, in a virtual one. Risk in the future will be better managed through more thoughtfully designed investigations and better communication of 3D data in a world of augmented reality.
