Data collection
Laser scanning
©2014 Real to Desk
 Accurate and complete as-documentation of
buildings and structures in a limited time frame
 Documenting existing buildings in their present
state; or monitoring construction of new projects
 Antwerp (Belgium); Constanța (Romania);
Chisinau (Moldova) offices

How it benefits you
Fast: very limited time to capture and process the data
Complete: point cloud data includes the smallest detail
Accurate: high-accuracy allows to make exact
measurements on the data
Cost effective: often cheaper than traditional survey

Applications
 Comparison of the as-built situation with
original design
 Point cloud and 3D models are the basis
for intelligent piping plant databases
 Buildings: monitoring of construction
progress, as-is documentation for
renovation project
 Revamp projects: clash detection and exact
positioning of tie-inn points
 Dimension control of prefabricated parts
Laser scanning
When accurate 3D
information is
required and the
circumstances don’t
allow traditional
surveying
