BIM FOR DESIGN & CONSTRUCTION October 2012 1

Slide 2

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.

BIM in Building Surveying 11 Typical Atkins survey notes

Slide 12

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

Slide 13

13 Surveying Tools in BIM 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 Build full scope laser capture Laser capture Existing south terminal - picture Amalgamated to produce a usable model Integrated into model environment Level Survey Points Cloud can be used to do a level survey and bring it in LandCADD / Siteworks for Revit / AutoCAD Civil 3d

Slide 14

This system uses sensors (cameras) held within the scanning head to capture the image of the object using triangulation techniques, resulting in a point cloud (or scan data). 14 POINT CLOUD DETAILED DATA

Slide 23

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 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

Slide 27

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
