Opportunities and impediments to the use of 3D laser scanning for adjacent excavations

Although three-dimensional laser (3DLS) scanning has been used to document and monitor individual excavation walls and structures on a limited basis, impediments remain to its use for major infrastructure projects. This paper outlines current technological opportunities and obstacles for using 3DLS to predict excavation-induced, damage prediction. Specifics are provided as to limitations regarding cost, optical resolution, processing time requirements,
data set convergence, data conversion, and data mining. Specific solutions are proposed to advance the state-of-the-art.
