Split spoon sampling is the industry standard for geotechnical and infrastructure projects. It is used anytime construction or major structural modifications are being considered, as the data produced influences the design and ultimate safety of the general public. Split spoon sampling can also be used for collecting environmental samples of the subsurface. Before sonic technology was common, split spoon was typically how core samples were retrieved. It is still used for this purpose when drill rigs can achieve the depths required; in such cases, a hole is drilled to the top of the interval needed for the sample (typically with auger or another traditional drilling method), and the split spoon tooling is driven in from there. For geotech and infrastructure projects, there is no viable alternative to split spoon or SPT technology. It is the industry standard method for measuring the load bearing capability of a potential construction site. For environmental sampling purposes, split spoon sampling is a solid choice of technology if you are simultaneously collecting samples while developing a well, or if you require core samples but have chosen not to use sonic for your drilling.
