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

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 can’t operate in BIM environment will quickly feel as
disconnected as one without email.” Chief construction adviser Paul Morrell

BIM in Building Surveying
Typical Atkins survey notes
11
123D Catch / ArtrA for conditional surveys
3d model be generated by taking multiple pictures on site or a video of
suitable resolution.
ArtrA for conditional surveys
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
Surveying Tools in BIM
Level Survey
Points Cloud - require Laser scanner – Highly effective to produce As built Model /
drawings. with accuracy of +/-2mm.
123D Catch - require an a camera with video functionality
Scan to BIM - Plugin for Revit to bringing in point Cloud
Points Cloud can be used to do a level
survey and bring it in LandCADD /
Siteworks for Revit / AutoCAD Civil 3d
Build full scope – laser capture
Laser capture
Existing south terminal - picture
Integrated into model
environment
Amalgamated to produce a usable model
13
POINT CLOUD DETAILED DATA
This system uses sensors (camera’s)
held within the scanning head to
capture the image of the object using
triangulation techniques, resulting in a
point cloud (or scan data).

Traditional vs BIM Design
22
Is central model FIT for Construction ?
Revit is good tool for designing, but BIM MODEL doesn’t necessary fit for construction.
To achieve BIM Model Fit for construction, use of BIM fabrication tools is preferable .
Showcase for visualisation
Revit for Architecture
Tekla for Structures
CAD Duct for MEP
Fabrication
Inventor for 3D mechanical design
Naviswork for design review
Vault or Buzzsaw for project / data management

BIM JOURNEY
BIM is continuously evolving

Limitations of SketchUp Data Imported to Revit
SketchUp is a surface modeller
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.
SketchUp and massing: Not all SketchUp imports are appropriate to massing. See Suitability of Imported Geometry. Also see Importing 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.
Trimble aims to make it BIM enabled

Collating and re-using project information.
As-built information:
how to gather, what is it,
where is it,
what can be provided and what is wanted.
Generation of O&M material.
Facilities Management
For example, will know exact sq.m.
to plan and cost.

BIM & CDM
Less work has been done for CDM to become part of BIM
but BIM has brought about a number of opportunities for
health and safety in a number of areas:
CDM could be part of BIM Execution PLAN.

Challenges within Atkins
Lack of Awareness / Clarity
Restrictions of tools.
Reluctance to change traditional practice.
Lack of training and support

Conclusion
Building surveyors and PMs need to be educated
Technical team meetings
RIP 2D AutoCAD
Decide the date for BIM Implementation
Flexibility needed in “I’ll do it my way” behaviour
Collaboration can only be achieved with communication
