4 Outline + Introduction + BIM Mindset + Training + Standards & Processes + Hardware + Integration + Model Sharing + Fees

5 Introduction What is BIM? 1. BIM is significantly more than 3-D CAD drawing. 2. BIM is the process of generating and managing intelligent building data during the building's life cycle. 3. BIM is a building design and construction methodology characterized by the creation and use of coordinated, consistent, and intelligent data about a building project in design and construction, and even into operation. 4. The key to BIM is the building INFORMATION model. 5. A BIM is a virtual prototype of the building.

6 BIM Mindset + 2 Main challenges to overcome in Mindset 1. Traditional Design/Bid/Build thinking and processes 2. Tempering Expectations from BIM

7 BIM Mindset + The current Industry process is traditional (design/bid/build)

8 AIA IPD Guide

9 AIA IPD Guide (applies to BIM)

10 + Challenges adopting IPD & BIM

11 BIM Mindset Tempering Expectations + Goal: to increase productivity and margins, create a better product, and increase value for clients To do this, would ideally have a detailed, fully coordinated Virtual Building from which we can coordinate systems, schedule construction tasks, obtain accurate cost estimates, and even fabricate and lay out systems Initially expect a single or linked models that are fully interoperable & coordinated

12 BIM Mindset Expectations + The realistic goal (in the near term) is that there will be multiple models (Architectural, Structural, MEP, Construction) that can be used to coordinate, schedule, and estimate costs

13 BIM Mindset Expectations The industry and tools have not reached the point where we can have a single model that can be used by all stakeholders for their respective purposes

14 BIM Mindset Expectations There will be some perceived duplication of work in creating multiple models and separate details, but in the long run, BIM will still increase productivity and quality, reduce schedules, improve cost certainty at various stages, and add value for the client

15 BIM Mindset + Cannot work in BIM and expect traditional deliverables (especially at preliminary project stages) Information is in the model, not drawing sheets Tagging, call-outs, etc. will be wrong, or not there at all Learn to review the model, not traditional drawing sheets

16 Leadership The key to success is Leadership*: + Leadership group must share aspirations create the current you want to swim in + *Credit to Ken Sanders, FAIA, Gensler at AU 2008

17 Leadership + Smart and talented people will surprise you with their innovation seek influence, not control

18 Leadership + Focus on those who want to innovate and achieve success let the laggards lag

19 Leadership + One word Integration technology/disciplines/partners/culture all have to integrate

20 Leadership Emotional Phases of Change: + Prophets pioneers with high thresholds for pain

21 Leadership Emotional Phases of Change: + Bandwagon More enthusiasm than understanding

22 Leadership Emotional Phases of Change: + Disillusionment Limits of technology revealed

23 Leadership Emotional Phases of Change: + The Right Stuff The payback for your investment begins to materialize Successfully navigating these phases means calibrating your pace of delivery

24 Training

25 Training + Mix of self-directed (tutorials, etc), internal (staff as trainers) and external (3 rd party trainers) training + Training must be practical, not just theoretical source trainers who use the tools regularly on projects

26 Training + Just in time training Provide training on projects when the tool will be used right away

27 Training

28 Training + Review knowledge and capabilities of all staff + Develop training plan tailored to the various levels that exist

29 Training + Continue ongoing training at these various levels Production Staff new to BIM Production Staff with some BIM knowledge Project Managers BIM Workflow

30 Training + Architecture Train on BIM workflow how different it is from regular workflow Train on creating and managing models to be shared with all disciplines

31 Training + Architecture Train on using model review software (Autodesk Design Review) Train on specification software (Especs) in relation to BIM Authoring tool Train on process decisions need to be made earlier

32 Training + Structural Train on not just modeling, but using BIM authoring software (Revit Structure) to generate Construction Drawings hands on training on projects

33 Training + Structural Train on analysis software and their interface with BIM authoring software Train on coordination and sharing of models with other disciplines & fabricators

34 Training + MEP Train on using BIM authoring software (Revit MEP) Initial implementation and hands on training on projects to generate construction drawings Train on analysis software (IES) and its interface with BIM authoring software

35 Training + MEP Train on energy modeling and lighting (including daylight) analysis Train on coordination and sharing of models with other disciplines & trades

36 Training + Construction Train on using estimating and scheduling tools (QTO/Navisworks/Vico) Train on constructability and clash detection reviews using BIM tool Train Site Superintendents on use of Virtual Model for visualisation, site coordination, clash detection, and scheduling

37 Standards and Process + Important items to address Modeling Standards Naming Conventions Content Standards Worksets (Revit) Exporting to CAD (you will still use CAD) Model Linking

38 Standards and Process + BIM Execution Plan Autodesk BIM Deployment Plan BIM Project Execution Planning Guide Developed for the buildingsmart Alliance by Penn State

39 Standards and Process + BIM Execution Plan Omicron uses customized hybridized version of both Outlines BIM goals and desired outcomes Defines what, how, and when to model based on BIM goals and desired outcomes

40 Standards and Process

41 Standards and Process

42 Standards and Process + Model Progression Specification Standard that defines levels of modeling detail required at different phases of a project Level 100 Massing model Level 200 Generic elements shown on 3D Design Development, many sizes not known Level 300 Specific Elements, Confirmed 3D object geometry Construction Drawings, Engineered sizes known Level 350 Fully Coordinated Model Level 400 Shop Drawing/Fabrication Drawings Level 500 As Constructed Drawings

43 Standards and Process + Model Progression Specification Also defines Model Component Author (MCA) Who models and controls what elements at various stages Arranged by uniformat structure (customize to suit) Customize the MPS to suit your policies and processes may be different for different projects

44 MPS

45 Standards and Process + New modelers have a tendency to over-model + Don t try to model all details + You don t have to model everything - Don t be afraid to use drafting views

46 Standards and Process + Level of Detail Define the purpose for each model and model only what you need to suit this purpose

47 Standards and Process + Level of Detail

48 Hardware + Get the best and fastest hardware that you can afford for power users 64 bit, Dual Quad cores, fastest front side bus (FSB) 12 gigabytes of RAM minimum Fast Video Cards, 2 gigs, Direct X 9 (10)

49 Hardware + Flow higher end computers to average users as you upgrade 64 bit, 4-8 cores, fast processor 12 gigabytes of RAM minimum Fast Video Cards, 1 gig, Direct X 9 (10)

50 Hardware + Multiple offices or locations Riverbed / accelerators WAFS Revit Server

51 Integration + Need to design and model the building more like how it would be constructed in the field. The structural skeleton should be the basis on which the Architectural skin is overlaid + Mechanical and Electrical blood and nerves are then installed and very closely linked and coordinated with the bones and skin

52 Integration + Team members need to understand what other team members need and to what level of detail they need it, at each phase of design and construction

53 Integration + Using Architectural Models for Engineering and Construction Analysis Ideally would be able to easily convert Architectural Models for use in analysis Doesn t work as easily as advertised Eg. Converting Architectural Model to use for Energy modeling Architectural models need to be created in a specific way We ve found it is currently easier to create the energy model from scratch

54 Integration + Omicron uses Revit suite or products Create separate models Architectural Structural Mechanical Electrical Construction Link models together and copy monitor critical items (grids, structural walls, etc.)

55 Integration + Coordination Low hanging fruit of BIM Can save enough in change order costs to pay for costs of BIM many time over Need not model everything Major Architectural, Structural, HVAC, Large Piping, Conduit, Cable trays, etc.

56 Integration + Coordination

57 Integration + Coordination

58 Integration + Coordination

59 Integration + Coordination

60 Integration + Integration with Construction Build Models the way the building will be constructed Eg. Columns should be modelled floor by floor, not continuous Slabs zoned to match concrete pours Allows for accurate quantity take-offs, estimates, and just-in-time delivery

61 Integration + Integration with Construction Model elements must have information required by Construction Codes mapped to CSI Master format or Uniformat cost codes Materials and quantity information for take-offs Elements broken out as required for sequencing

62 Integration + Integration with Construction Allows for realistic 4D sequencing simulations Can tie model elements to scheduled tasks Model assembly codes that can be used for scheduling and estimating Revit / Timberline estimating / Timberline Accounting / Especs / Navisworks

63 Integration + Sequencing model BC Hydro Horne Payne Building (Burnaby, BC) Jaguar/Land Rover Dealership (Victoria, BC)

64 Model Sharing + Sharing model with Trades For information only? For visualization? To form part of Contract? To take off quantities? Expedite or eliminate shop drawings? Legal implications + Currently difficult (in local market) to find BIM capable trades

65 Fees & BIM

66 Fees & BIM + Overall project costs to owner should be lower (including change orders etc.) + Need to re-think the traditional distribution of Design Fees + Construction Managers may require more CM fee, but should result in fewer RFIs, change orders, etc.

67 Fees & BIM + Depending on levels of detail and uses modeling effort could take more time than traditional drawings + Who benefits? Owner Contractor Designers Everyone!

68 Fees & BIM + Shared compensation model Overall project costs lower Sharing of saved costs among entire design and construction team Owner benefits with lower costs, shortened schedules, and better quality

69 Implementation + Start using various BIM tools on projects, but not all at once Staged process - implement various BIM components or tools one at a time on different projects + Develop and implement methodology to link various models together + As use of various BIM tools becomes more successful, begin using multiple BIM tools on projects

70 Implementation

71 Implementation + Find or develop tech savvy people who are excited about BIM + Staff building models have to also know how a building is actually built can t fake-it like in CAD + Process, Process, Process

72 Final Thoughts + BIM is inevitable get on board or get left behind + There is no Easy button + Implementing BIM is not as simple as some think can t just buy BIM software and think you are now doing BIM

73 Final Thoughts + Most difficult aspect of BIM implementation is changing traditional mindsets, expectations, and processes + Industry hasn t even started scratching the surface of what is possible - efficiency, integration & interoperability, facility management, etc.
