First ITED's partners made a laser survey which proved to be challenging because of the density of the structures and difficulties to avoid "blank spots". Then the laser scans were brought into Revit for modelling. The shell of the building was modelled first, then the structural elements which was the most difficult task because of their vast numbers and various arrangements. Hundreds of sections of the point cloud were made to get better understanding especially of those places were scanning could not be done properly. The surrounding building and site objects were modelled last.

The result was a manageable, complex 3D model which contains far more information than the available 2D documentation. Having this Revit model allows more detailed and thorough interegation on the facility information for future design work such as being able to select and identify assets and the ability to cut sections through any part of the building. During the modelling a dangerous crane support offset was found which by clients words "was a very helpful find and may have avoided serious incident."
