Opportunities and Impediments to the Use of Three-Dimensional 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, data set convergence, data conversion, and data mining. Specific solutions are proposed to advance the state-of-the-art.
