A laser scanning system can be used in construction projects to generate a
field survey. An architect or engineer can use the field survey to create
construction drawings. In addition, relevant points from the construction
drawings can be identified at the construction site with the scanning
system. Further, earth moving equipment can be controlled using the same
information. The laser scanning system can be used to determine if two
parts can be mated together by scanning and comparing the parts that are
to be mated. The laser scanning system can further be used to determine
if an object can be moved through an opening in a structure by comparing
scan points of the structure with scan points from the object. The laser
scanning system can be used to identify objects within the site, to build
databases that have relevant information about the objects, and to guide
reproducing machines.
