4 BIM Level 2 Pathway Part of the BRE Trust

5 UK BIM Maturity Levels Strategy Paper 2011

6 BIM Level 2 - Key Documents PAS1192-2:2013 PAS1192-3:2014 BS1192-4:2014 PAS1192-5:2015 BIM Protocol (CIC) BS :2015 Classification Digital Plan of Work

7 BIM Deliverables Part of the BRE Trust

8 Drawing Board: Paper Deliverables

9 CAD (Electronic Drawing Board): Paper Deliverables

10 BIM Models: Paper Deliverables

11 COBie: Structured Data! Construction Operation Building information exchange

12 Pathway to Collaborative Objects Part of the BRE Trust

13 BIM Object - What is it?

14 BIM Object - What is it?

15 BIM Object - What is it?

16 BIM Objects: Meta Data Validation Content Requirements (SMPs) Manufacturer Specific Content Contractor Specific Client Specific Out of the Box Content Open Content Information Source Is it correct Is it coordinated Is it up to date

17 BIM Object: Standards BS 8541 Series British Standard BS 8541 Series However, there are many other UK published Standards and software vendors Standards But what about the rest of the world

18 BIM Object: Level of Graphical Detail (LOD) Define an International Standard for Levels of Graphical Detail. US - LOD 100, 200, 300, etc UK 1,2,3,4,5,6,7 UK - Low, Medium, High, Visualisation Symbology

19 BIM Object: Graphic Standards Window Hinges Top or bottom hung? BS : hinged on top Australian Standard AS 1100: 301 hinged on bottom

20 BIM Object: Naming Standards Brick Wall Brick Wall BRE-Wall_Internal-Pl_Block_190_Pl BRE-Wall_Internal-Pl_Block_Pl

21 BIM: Object Naming Standards Example Family = 42 TV Type = Plasma, with Stand & remote CSV File writes Family, Type, Url 42 TV, Plasma, with stand & remote, CSV File reads Family = 42 Type = TV URL = Plasma

22 BIM: Parameter Naming Conventions Rectangle??

23 BIM: Parameter Naming Conventions Rectangle A B X Y Length Breadth Width Depth XDIM YDIM??

24 BIM: Parameter Naming Conventions You choose Length LENGTH length Lentgh PaulsLength pauls_length

25 BIM: Object Insertion / Base Points Common Insertion / Base points

26 Object Modelling Standards Graphical Representation Object Categories Classifications Naming Conventions Model Break down Structures Model Progression Strategies Object History Ownership Location Points Units

27 Pathway to Structured Data Part of the BRE Trust

28 COBie: Structured Data! Construction Operation Building information exchange

29 Construction Operations Building Information exchange

30 BREEAM Compliance Process BIM Award Process

31 BREEAM Compliance Process Obstacles to Compliance

32 BIM Level of information (Graphical and Non Graphical)

33 Window Object: Asset Lifecycle Questions Strategy: Is there adequate natural light? Brief: Is there adequate natural light to habitable rooms? Concept: Are there appropriate windows and/or roof lights to habitable rooms with required glazed area? Detail Design: Do relevant building areas meet good practice daylighting criteria as BREEAM HEA 01? Construction: Do the Window and/or roof light meet the specification criteria to meet detail design requirements? Operations: How do I operate / use the window? Maintenance: How do I clean and/or replace? End of Life: What is its residual value and recyclability/reuse properties? Disaster: Help it s been vandalized! How do I replace the glass?

34 BIM Lifecycle Questions Disaster Help it s been vandalized - Glass Broken! Where is the window? Location Properties What is the size and type of the replacement glass? Glass Size Properties Glass Specification Properties How is it beaded Beading Properties

35 The BIM Object Solutions Part of the BRE Trust

36 The Object Library Solution All use different standards No complete range of products Differing Quality Not compliant with BS8541

37 BIM Objects: Revit Standardised Parameters Window Type Description Description description description 2000x1500mm-Double Wooden casement window 910x1210mm Window Arc Sash 900x1200mm Window Plain 1500x1200mm-Single Casement Timber Window
