2 David Hymas Technical Director - BNI Building Services Engineer Building Services BIM Champion for MM Mott MacDonald 4 Years 18 Years Multi Professional Architectural Practice

3 Multinational We work in 140 countries On some 16k projects From 200 permanent offices Across SIX continents

4 It s our diversity that makes us unique

5 Presentation Contents What is BIM? The Outputs The Process The Opportunities

6 What is BIM The Designer

7 Building Information Modelling BIM Mott MacDonald s definition: 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

8 The Benefits of BIM

9 BIM is for the whole lifecycle BIM Model Source: Autodesk

10 BIM for the built environment Road Map

11 What Is BIM The Outputs

12 Multi-disciplinary co-ordination

13 Multi-disciplinary co-ordination

14 Multi-disciplinary co-ordination

15 Multi-disciplinary co-ordination

16 VSU clash checking

17 Conveying design intent

18 Conveying design intent

19 Success stories Water treatment, USA 20% Cut on design time

20 Maze Stadium, Northern Ireland 15% Time saving to structural design Revit, robot and Navisworks images

21 Royal Welsh College of Music & Drama Revit Structures Model export to Structural Analysis 3DS Max Robot Structural Analysis Revit Structures CSI Etabs

22 Navisworks used for clash detection Revit structures Navisworks AutoCAD

23 Royal Welsh College of Music and Drama

24 Royal Welsh College of Music and Drama

25 Royal Welsh College of Music and Drama ZERO Redesign required during construction

26 Design The Process

27 The Design Funnel A need - A site An idea Some Constraints A design

28 Which Way Do We turn?

29 To Deploy BIM it is Both: A Noun and a Verb It is both a virtual object and a process For BIM to work as a process, interoperability is key (Data push/pull)

30 Structural Engineering Structure is Easy Isn t it? Lots of similar elements repeated many times

31 Hand Sketches Workflow Concept Stage New tools Rhino Grasshopper + Structural Plug-in Enable quick design using Architects geometry and models Visualisation Tools Penguin (non-photorealistic renderer) Sketch Up Pro Grasshopper - Rhino Rhino Plug-in import/export Robot A B C D Concept stage RIBA Stages E F G H J K L M

33 The MEP Step Change - Early Analysis Bringing analysis into conceptual stages of design. Visual Impact Solar Position Overshadowing To consider all aspects of building performance. Vasari/Ecotect or something else? Shading Optimization Solar Availability Incident Radiation Shading Design Envelope Design Daylight Analysis Thermal Performance Acoustic Design Rights-to-Light

34 Building Energy Performance MEP Volumes and demands on those volumes

35 Where does stuff go Lighting Analysis

36 Schedule Counting things again

37 Which Way Do We turn? 9 variables 1.2 million solutions Building form various 6 Orientation 35 through 60 degrees north 25 Roof overhang depths per facade 6 Glazing ratio 25% 28% 30% 3 Glazing G values 3 Daylight none daylight linked glare and daylight 3 Structure Steel Concrete (Mass) 2 Building Fabric U Value performance combinations 5 Window Construction performance combinations Cost /Time? Embodied Energy?

38 Embodied Energy as a Variable

39 Which Way Do We turn? Building Design/Project Quality. Optimise Energy Consumption, Optimise Space, Optimise Equipment Size, Optimise Embodied Energy, Optimise Cost, Scheduling, Optimise Build time, Optimise building operation, Optimise beauty? Arrchitecture

40 The outputs The Opportunities

41 Anglian Water product based delivery BIM hugely facilitates offsite manufacture

42 Anglian Water product based delivery 90% Time saving 20% Less Carbon

43 Optimisation The Challenge

44 Optimisation The Ultimate
