BIM FOR DESIGN & CONSTRUCTION

1. BIM FOR DESIGN & CONSTRUCTION October 2012

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

3. BIM and You TYPES OF BIM Team BIM Ultimate / Client BIM Lonely BIM

4. 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

7. How does we react Go away BIM

8. Coming Soon In theatres CLIENT BIM MOJ is setting an example Are we really late?

9. Atkins BIM Preparation • BIM Strategy • Atkins BIM Strategy Document • BIM Standards • Atkins BIM Standard Document • BIM Templates • Atkins Template – Need to be reviewed • BIM Execution plan • Could be changed on project basis • BIM Library • Central Library – NBS Library

10. Key ingredients for BIM • A PROJECT • ENTHUSIASTIC PROJECT MANAGER / ARCHITECT / BUILDING SURVEYOR • ENTHUSIASTIC BIM COORDINATOR

11. BIM in Building Surveying Typical Atkins survey notes

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. • ArtrA for conditional surveys

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 Level Survey 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 Existing south terminal - picture Laser capture Integrated into model environment Amalgamated to produce a usable model

14. 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).

15. WORKFLOW BIM COORDINATION WITHIN COLCHESTER OFFICE • Architecture Structure Services BIM Coordinators Architectural Technician MobeenMinai Adam Livermore Central Model on P:\ /Cloud Landscape / Infra structure CAD Structure CAD M&E CAD Structure Coordinator / Super ser Landscape Super User MEP Coordinator / Super Use Jonathan Hesketh Declan Gildea Andy Boutle Joe Vyse Adam Baker Note: This is not a management structure

16. Case study shows that this structural detailing workflow can convert 286 man hours into 42. Concrete Detailing Steel Detailing

17. Services installation workflow • Revit MEP CAD Duct Navisworks BENEFIT OF BUILDING TWICE Workflow, review and approval process. Pre-construction coordination and clash detection/prevention. Quantity takeoff - cost estimating. 4D construction sequencing - pre-tender/post tender. Autodesk 360 Revision technique Clash detection

18. Coordination • example

19. Case Study – OFFSITE Manufacturing Anglian Water Product Based Delivery Can be used for modular construction, such as relocatableclassbase.

20. RIBA Plan of work 2013 Mapping the new Plan of Work, and alignment with the current proposed CIC stages It has been design to suit BIM Workflow BIM workflow

21. Dimensional Construction

22. Traditional vs BIM Design Recommended BIM

23. 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

24. BIM JOURNEY • BIM is continuously evolving 2DCAD to BIM: The more we procrastinate , harder to learn. Will miss the level 3 target set by Govt for 2016

25. NBS Library NBS Library of parametric driven families • Integrated Project Delivery

27. 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

28. BIM Handover • On Cloud – Central model • 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.

29. Grey Areas • Contract Legalities • Ownership

30. 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.

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

32. Progression • Seminars • Webinars • Conferences • Training • You TUBE • Autodesk University

33. 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 • Communicate , Communicate , Communicate

34. BIM Adoption Percentage of BIM against USA, UK , FRANCE and GERMANY • BIM USAGE REACHES 74% AMONG CONTRACTORS IN USA • UK 35% • FRANCE 38% • GERMANY 36%
