What is BIM a coordinated set of processes, supported by
technology, that add value through creating, managing and sharing
the properties of an asset throughout its lifecycle Competitor Its
a complete representation or depiction of a building that aids in
its design, construction and on going management Paul Aubin 2

Government BIM In 2007 Government Construction Strategy
outlines the plans to reduce government construction project costs
by 15 to 20%. BIM has demonstrated that it can achieve this level
of cost savings. Govt intention to require collaborative 3D BIM
Level 3 on all govt. projects by 2016. Level 2 BIM (i.e. COBie) is
currently required for this year. any practice that cant operate in
BIM environment will quickly feel as disconnected as one without
email. Chief construction adviser Paul Morrell 4

123D Catch / ArtrA for conditional surveys 3d model be
generated by taking multiple pictures on site or a video of
suitable resolution. This can insert in Catch to build a 3d model
or a *.obj file can be obtained to use in Revit. Its not as detail
as point cloud but effective to build existing model. 12 ArtrA for
conditional surveys

Is central model FIT for Construction ? 23 Revit is good tool
for designing, but BIM MODEL doesnt necessary fit for construction.
To achieve BIM Model Fit for construction, use of BIM fabrication
tools is preferable. Showcase for visualisation Revit for

Limitations of SketchUp Data Imported to Revit Revit treats the
data imported from Trimble SketchUp as a large block of geometry
that resists being manipulated (in the ways that you can usually
manipulate geometry that is native to Revit). Exploding 3D data: In
Revit, you will not be able to explode 3D data. If you try this, 3D
faces will disappear, and you will receive a warning message.
Parameters: In Revit, you cannot add parameters to control
geometric flexing. However, you can add some controls that
manipulate imported data, such as the location of an imported
element and its material assignments. Visibility/graphics: In
Revit, you cannot manipulate the geometry or isolate parts of whole
elements with visibility/graphics settings. Two-sided surfaces: If
a material or color is assigned to only one side of a surface in
SketchUp, Revit applies the material or color to both sides of the
surface by default. If there is material on both sides of the
surface, Revit applies the Face 1 material to both sides. If faces
are flipped and painted differently in SketchUp, they may not
display the correct material in Revit. SketchUp properties: The
following SketchUp properties are currently not supported in Revit
import: Texture Image Maps, Transparency, Smooth Curved Surfaces,
Text and Dimensions, Raster Images, and saved Pages. Cut planes:
Imports cannot be cut by a cut plane unless imported into a
cuttable family category. See Cuttable Families.Cuttable Families
SketchUp and massing: Not all SketchUp imports are appropriate to
massing. See Suitability of Imported Geometry. Also see Importing
Massing Studies from Other Applications.Suitability of Imported
GeometryImporting Massing Studies from Other Applications Scaling:
Groups or components that have been scaled in their entirety with
the SketchUp Scaling tool may be incorrectly scaled when imported
to Revit. Exploded SketchUp models should import at the correct
scale. 27 SketchUp is a surface modeller Trimble aims to make it
BIM enabled
