3D scanning and modeling
High-definition surveying and terrestrial lidar (also known as 3D laser scanning) are used to digitize the physical features of a site or structure—even those not typically visible from the ground or air. Barr uses state-of-the-art instruments that capture millions of data points to which colors can be applied, creating three-dimensional “point clouds” that designers, engineers, and clients can use for various purposes, such as developing highly accurate models of existing piping to facilitate retrofits and reporting the volumes of containment ponds. Perhaps the most intriguing application of these technologies is constructing 3D views of normally unseeable things like lake bottoms and contours; mine-tailings deltas that aren’t accessible by foot or by boat; and equipment that can’t be inspected due to hazards like high heat and rapid motion.
