A method of locating anchor bolt openings in a prefabricated panel includes positioning a laser scanner on or near a concrete slab, foundation or other surface. The concrete slab can include a plurality of embedded anchor bolts, pipes, conduits, stubs or other items. As-built coordinate data regarding the concrete slab and the plurality of anchor bolts, pipes, conduits, stubs or other items can be collected using the laser scanner. The as-built coordinate data may be used to create a layout of openings in the prefabricated panel.
