1 Getting Started with BIM (Building Information Modeling) Curt Egli Synergis Building Solutions Engineer

2 Session Summary This session will walk you through issues you should consider when strategizing, planning and executing on your transition to BIM to ensure your success.

3 Agenda Framework for Substantive Change Forms of Solutions: Pro-actions/ Reactions Tools Hardware Software Processes People Challenges/Opportunities

4 Crucial Questions What factors into a workable size BIM project? Number of team members Size of file Square footage Complexity What do big BIM projects all have in common? Perception Unpredictability Need for collaboration Why do big BIM projects warrant concern? Drain resources of time & money Lessen ability/likelihood to/of succeed/success Force stressful tipping points What is within your control? Capability of teams Understanding of methods to achieve success Familiarity with solutions

5 BIM Implementation Framework Forms Tools Applications, data files, parameters, templates, folders, workstations, servers (real and virtual), networks connections Processes Standards, protocols, workflows, project reviews, file audits, content creation, content modification, content approval People Modelers, designers, project managers, BIM champions, BIM managers, content creators, data managers

6 . Forms of Solutions: Pro-actions/Reactions

7 Forms of Solutions Overview Tools Hardware End Users Networks Software End Users BIM Managers Additional Tools Processes BIM Project Execution Planning Collaboration Standardization People Roles /Responsibilities Training

8 Tools Lets Talk Tech Hardware Workstations What hardware do we need to efficiently execute this project? Does everyone need the same hardware or the same performance? How to make the business case for procurement? Networking Where are my teams located and how do connect them? How do we maximize bandwidth, but minimize costs? Where does virtualization fit in?

9 Tools Hardware Requirements People cost more than workstations

10 Tools Processor Speed Cores Revit is multi-threaded Vector printing 2D Vector Export such as DWG and DWF Rendering (4 Core Limitation lifted in Revit 2011) Wall Joins representation in plans and sections Element Loading. Loading elements into memory is multi-threaded, reducing view open times when elements are displayed for the first time in the session. Parallel computation of silhouette edges (outlines of a curved surfaces) in perspective 3D views. Engaged when opening views, changing view properties, and navigating the view and will be more noticeable as the number and complexity of curved surfaces increases. Translation of high level graphical representation of model elements and annotations into display lists optimized for given video card. Engaged when opening views, changing view properties and will be more noticeable as the number and complexity of model elements increases. File Loading Point Cloud Data Overlay

11 Tools Hard drive SSD (solid state drive) = Speed Impacts not just Revit.

12 Tools Memory ~20X file size when expanded in Memory 32 GB RAM recommended for management of large models. Do More not really faster (that s the processor)

13 Tools Graphics Card DirectX 10 capable GPU with Shader Model 3 (but make sure your card choice is on the Autodesk (Revit) tested cards list)

14 Tools What's the worst that can happen? Stress, Stress, Stress, and worse project death Poor performance, slow response times Inability to do common tasks Printing Exporting Navigation of the Revit Model Worst Case Scenario Complete halt to the Revit Project, abandonment

15 Tools Servers File servers Windows based HD speed Avoid DFS (Distributed File Systems) but it can work License Servers Bandwidth Whatever is supported Don t do Redundant configurations

16 Tools Network Infrastructure Networking can be the weak link to the best organizations. Performance, performance, performance How do you speed it up? Increase bandwidth Manage usage (People) Re-organize configuration Reduce data through-put The better the bandwidth, the better for Revit. Network latency should not exceed 100ms

17 Tools Revit End Users New Local File Daily Communicate and coordinate Syncs with Peers Worksharing Monitor / Bluestreak Follow Workset creation guidelines and usage Use Specify Open Working views Views are Cheap Ensure local backups Take care with UserName and ensure consistent file pathing

18 Tools BIM Managers With large projects, the BIM Manager plays a important role in the Health of the project Their decisions will often make or break the project work Good BIM Managers are engaged with People, Process, and Technology.

19 Tools Deployment Prep Do you need to create deployments for different groups of users based on discipline, software features, and settings? What Revit out of the box content do you need? How can / do you want to manage content? How will you manage add-ins? Where will user projects and files reside? Which user settings do you want to specify? Revit Server? Do you need to create 32 bit and/or 64 bit deployments? For network licensing, what is your license server model? How do you want to distribute/access your licenses across your enterprise?

20 Tools Revit - Template Pre-configuration requirements Project Browser Object Styles, Line Styles, Line Weights Shared Parameters Families Materials Annotative Objects

21 Tools Revit - Template Pre-configured Project Browser Base it on team composition Can be used to organize tasks Filtered to show qualities Ownership Completeness Inclusion/exclusion in submittals Can be grouped for easy access

22 Tools Revit - Template Pre-configured Object Styles, Line Styles, Line Weights

23 Tools Revit - Template Pre-loaded Families, with required parameters Doesn t hurt to load what you need size of the template shouldn t be deterrent if known size of project

24 Tools Revit - Template Pre-configured Schedules and parameters

25 Tools Revit - Template Consider. If you don t put it in ask, how will my people find what they need? Plan to adjust over time Change Management handing Consider starting size vs. ease of use vs. expected project end size

26 Tools Revit - Worksharing Worksharing Best Practices New Local File daily Consistent network locations \ mapped drives Consistent workset naming Each user has unique username Set synchronization intervals for project teams must manage the people!

27 Tools Revit - Worksharing Workset Organization Effective Workset Strategy Selective Open Workset Naming Consistent Application

28 Tools Revit Shared Coordinates The coordinate system causes many more issues than it should on projects. Pre-defined organization and methodology clearly documented and communicated Project Internal vs. Shared Coordinate systems Consistent set-up and management Set it in beginning AND don t change it without planning!

29 Tools Revit - Maintaining the Project Schedule Regular Maintenance Purge Unused Audit Save As (with new name) New Locals for All wipe the old away. Monitor Project Size and Family Sizes Reduce Family Complexity Clean up imported content Health Checks at key intervals consider project phases as key milestones for checking the model.

30 Tools Revit Server When should Revit Server be a part of helping manage a larger BIM project? Clear division of work for multiple teams accessing same data Firewall restrictions considered Different locations working on different data removes the need Distance is an issue BIM managers have time and expertise to help manage it

31 Tools Other Tools/Functionality What are other solutions needed for large BIM projects? Navisworks, 360 Glue These aggregators help teams coordinate through mitigating clashes and issues Chat programs (Bluestreak, etc.) Help quick communication through awareness of work stream communication is key! API (Application Program Interface) Third-party BIM and Data standards such as COBie and IFC to improve collaboration Revit 2014 Interop with CAD geometry - Solids explode to real components, expanding Interop with other tools

32 Forms of Solutions Processes We have good tools, but are we using them right? Process is the means by which we deploy tools and invariably is more important to the success to large projects than any application. BIM Project Execution Planning How is BIM to be deployed on this project? Collaboration Workflows How and When do we share data effectively? Standardization How does everyone know the proper format of the deliverables?

33 Processes Project Execution Plans The BIM Project Execution Plan defines uses for BIM on the project (e.g. design authoring, cost estimating, and design coordination), along with a detailed design of the process for executing BIM throughout the project lifecycle.

34 Processes Project Execution Plans (continued) Autodesk BIM Deployment Plan (Enterprise and Project) Establish organizational and project team business practice standards Bind all parties early in project and define roles and responsibilities Define model types and requirements Set parameters for visualization, simulation and analysis Standardize communication and collaboration practices Level of Development is key

35 Processes Project Execution Plans (continued) AGC Consensus Docs / BIM Addendum / Execution Plan AIA IPD Guide / E202 CIC BIM Project Execution Planning Guide NIST General Buildings Handover Guide FIATECH Fully integrated and automated project processes CURT Collaboration, Integrated Information and the Project Lifecycle GSA BIM Standard NIBS National BIM Standard 3xPT Strategy Group CURT, AGC and AIA collaboration AIST CIMsteel Integration Standard Some Examples:

36 Processes Collaborative Workflows Model Creation Design Workflows DIGITAL PROJECT AutoCAD Revit Pre-Design Schematic Design Design Development Construction Documents

37 Processes Collaborative Workflows Documentation via the federated model

38 Processes Standards Project Standards make everything easier if they are followed

39 Forms of Solutions People People are more important to a large BIM project than any tool or process Culture Organization Training Assessments Skill Foci Skills Matrix Applications Standards Workflows Maintenance.

40 People Who s on our team? When a team is performing at its best, we'll find that each member has clear responsibilities and every role needed to achieve the team's goals is being performed well. Recruiting Team effectiveness Coaching Motivation Delegation

41 People Roles Organization is a crucial part of any well-oiled machine. Without it, how are responsibilities known? Typical BIM Roles Design Manager Model Manager or Revit Champion Content Creation Specialist Discipline BIM Coordinators Data Coordinators Project Specific Role.
