Constructing greenfield rail requires communication of complex ideas and concepts, inevitably with some loss of information along the way. Some of the most common sources of geotechnical information for greenfield rail projects include the results of geotechnical boreholes and test pits. One of the advantages of test pits is that they provide a much greater lateral extent ‘window’ into the conditions at a test location, exposing conditions with horizontal spread, not just vertical depth. It would be immensely useful for the project team to walk through the site while the test pits are open, particularly for earthworks in challenging soil types.
