1. An ARNG ProjectAutodesk Revit Case Study Mark Da Gama Rose Design Technology Manager – JACOBS

2. Class Poll Audience Composition: • Architect/Interior Architect • Engineer (Structural/MEP) • Principal • IT/BIM Manager

3. Class Intentions • Stress How Early Decisions On A Project Have A Lasting Effect • Talk About What Worked And What Did Not Work • Show Recent Solutions To Issues That Arose On INARNG-AFRC • Stress That It’s All About The Process • Communication And Standards Are Key Especially As A Project Is Hampered By Its Weakest Link

4. Class Topics • INARNG-AFRC Project Background • BIM Mentality And Process • Expectations – Both Internally and of Client • Hardware • File Linking • Worksharing And Worksets • Model Performance Checks • Challenges And Decisions Made Within Each Discipline • Coordination Between Disciplines • Construction Document Creation • Making CAD Files Compatible With AEC 3.0 CAD Standards • Revit To 3D Studio Max Rendering Process • Summation And Closure

5. INARNG-AFRC Project Background Purpose: Joint Armed Forces Reserve Center to serve the peace-time missions of the assigned unit and space for all personnel to perform the necessary tasks that will improve the unit readiness posture Project Size: 168,095 SQ. FT. • Design Deliverables:

6. INARNG-AFRC Project Background • Building’s permanent masonry-type construction consisted of: • Slab-On–Grade First Floor And Elevated Steel Structural System For The Second Floor • Brick And Concrete Block Units With Concrete Floors • Exterior Masonry Walls Combined With Interior Masonry And Steel Stud/Gyp. Board Partitions • Steel-Framed Roof Structure – Combination Membrane/ Sheet Metal Roof Primary Spaces Include: • Office Areas • Classrooms • An Assembly Hall • Commercial Kitchen • Locker Rooms • Military Unit Storage Rooms Including Arms Vaults, Mechanical, Electrical And Equipment Rooms

7. BIM Mentality and Process THINK BEFORE YOU DO – BIM Process as important as the: • Hardware Specs • Software Version Limitations • Team’s Learning Curve EARLY REVIT DECISIONS CAN HAVE A LASTING EFFECT ON THE PROJECT Key Steps in the project: • BIM Strategy Call • BIM Kickoff Meeting With Team • Maintain A Living, Breathing BIM Implementation Plan Throughout The Project

8. Expectations – Both Internally and of Client • Per the Client’s Scope of Work the only final documents of record were AutoCAD files • However, Jacobs’ internal mandate is to do projects in BIM…. This project was done using the Autodesk Revit 2009 platform

9. How were those Expectations Managed? • Strived To Plot All Construction Documents From Revit • Team Member Support Came From BIM Coordinator And Revit Discipline Leads • Tried To Have Weekly Bim “Lunch And Learns” • Needed To Have A 5 Minute “Huddle” For Revit Discipline Leads Just Because We Develop A Model Does Not Mean We Deliver A Model….Client Expectations/Budgets/Staffing/Billable Hours

10. Hardware • Revit Discipline Leads Had Dell T5400s – 64 Bit (Specs: 8GB RAM, 3.16 GHz, 512 MB Nvidia Video Card) • Most Team Members Had Dell T3400s (Specs: 4GB RAM, 3.16 GHz, 256 MB Nvidia Video Card) • One Rendering Computer: (Specs: Dual Quad core; 8GB RAM; Xeon Processor) • All Users With Dell T3400 Had 3gb Switch Enabled And Paging File Increased To 8GB • All Users Had Gigabit Switch To The Desktop Connections

11.

12. File Linking 3 Main Reasons Why Discipline Models Were Separated Out: • Each Discipline Controlled Their Own Drawing Sheet Set • Prevented Disciplines “Stepping On Each Other’s Toes” Concerning Element Borrowing And Relinquishing • Model Performance Was Controlled Through The Opening And Closing Of Linked File Worksets

13. File Linking Negatives To Linking By Discipline • Systems Connections • Limitations on Tagging through the Link • Split Architecture from Interiors? • File Management Issues Magnified • Communication Needs To Be Especially High

14. File Linking A “Model” And Typical Detail File Was Created For Almost Every Discipline • Pros: • Model Performance • Streamlined Discipline Workflow • Cons: • View And Sheet Referencing • 2 Files To Manage Settings And Coordinate Drawings for Submittals • Need To Be Very Clear Whether Drawing Sheets Are Located In “Model” File Or Typical Detail File

15. File Linking Important Considerations: • Renaming The Linked Instance • Pin Linked Instance • “Make Editable” Linked Project Files • Keep Same Name Of Linked Central Files (Project Prefix-Discipline Initial-CENTRAL.RVT) • INARNG-AFRC-A-CENTRAL.RVT • INARNG-AFRC-M-CENTRAL.RVT

16. File Linking INARNG-AFRC-DRAWINGINDEX.RVT Separated Out For Two Reasons: • Model Performance • Architectural Workflow – Allows Specialization Of Task

17. File Linking INARNG-AFRC-DRAWINGINDEX.RVT Downfalls • Time to Open Project File • Discipline Management Process • Sorting/Grouping of Discipline Sheets

18. Worksharing and Worksets “LARGE CHUNKS OF THE MODEL” Need Mentality “Why Do I Need To Create A New Workset?” Uses: • Workflow • Model Performance • View Visibility Control – Inside Of Project File • View Visibility Control – Between Project Files

19. Worksharing and Worksets Key Project Aspects: • Workset For Each Linked File • Minimal Amount Of User Created Worksets • Element Workset Classification Identified And Updated In BIM Implementation Plan • Naming Convention • *LINKED MECH • *LINKED STRUCT • Shell • Core

20. Worksharing and Worksets Key Project Aspects: • Only Discipline Leads Were Allowed To Create New Worksets • Checking Active Workset • Workset Classification Correction • Best Approach To Relinquishing? • Workset View Visibility (View Specific) VERSUS Closing Worksets (Global)

21. Worksharing and Worksets Key Project Aspects: • Taking Advantage of Closing Worksets • Element Borrowing Was Heavily Used Making Worksets “Editable” Allows 2 Main Benefits: • Prevents Anyone Else From Manipulating Elements Tied To That Workset • Revit Does Not Constantly “Ping” The Central File About Who Is Borrowing Elements Of That Workset

22. Model Performance Checks • **Open/Close** Drafting View • 64 Bit Machines To Plot Out Submittals • Benefited From Using The 3GB Switch • Close Worksets When Possible • Work In Wireframe/Plot In Hidden Line • Review And Fix Warnings • Family Detail Level & Visibility In Plan/Elevation

23. Challenges and Decisions Made Within Each Discipline Common Challenges Amongst The Disciplines • Proximity of Team • Worksharing Monitor Usage • Saving & Relinquishing • Specialization of Task • AutoCAD Versus Revit Newbie Mentality • Ghost of Revit

24. Challenges and Decisions Made Within Each Discipline Architectural Challenges • “Elements Have Duplicate Mark Values” • Team Members Rotated In And Out • Wall Join Conditions

25. Challenges and Decisions Made Within Each Discipline Interiors Challenges • Adding Room Tags • Interior Elevations • Maintaining View & Sheet Consistency • Tile Patterns • Material Legend

26. Challenges and Decisions Made Within Each Discipline Structural Challenges • Coordinating Design And Revit Production Workflow • Custom Truss Creation

27. Challenges and Decisions Made Within Each Discipline Mechanical Challenges • Systems Creation • Family Creation

28. Challenges and Decisions Made Within Each Discipline Electrical Challenges • Circuit Creation • Content Creation

29. Challenges and Decisions Made Within Each Discipline Plumbing Challenges • Filters Distinguished Pipe System Types By: • Color (Graphically) • Linetype (for construction documents) • Export Mapping To Systems Layers In AutoCAD • WAN workflow

30. Challenges and Decisions Made Within Each Discipline Fire Protection Challenges • Sprinkler Pipe Creation

31. Coordination Between Disciplines • Setting Structural Usage of Walls • Assigning Family Category & Sub-Category • Room Volume Coordination & Workflow • Room Tag Coordination & Workflow

32. Coordination Between Disciplines • To Host Or Not To Host? • Structural Column Grid Updates • Owning Linked Worksets • Concrete Plan to Prepare for Submittals

33. Construction Document Creation • Browser Organization – Crucial For Views And Sheets • Need To Sort By Working And Sheet Views And Then By Sub Discipline If Needed • Did not implement effectively on INARNG-AFRC

34. Construction Document Creation • Did Not Really Use Dependant Views • Had To Use Masking Regions As A Polygonal Viewport Clip

35. Construction Document Creation • View Templates • Not Enforced From The Start & Maintained Thereafter On INARNG-AFRC • Very Important To Set Up In The Beginning • Need To Have One For Each Type Of View – Should Be Part Of Template • Helps Alleviate “Ghost of Revit”

36. Construction Document Creation • Only Copy/Monitored Structural Column Grids And Levels • Section Cuts Apparent In Multiple Plans • MEP Disciplines Could Not Show Arrowhead On Space Tags

37. Construction Document Creation • Instead Of Keynotes (Could Not Number By Keynote Or Sheet) We Used Note Blocks • All Keyed Notes Per Type Of View Listed Regardless Of Shown Or Not • Strike Through Keyed Notes Not Applicable To View • Needed To Have Note Block And Corresponding Tag For Each Type Of View That Has Keyed Notes

38. Construction Document Creation Details • Imported And Exploded In Revit • Replaced With Detail Components • Incurred Numerous “Line Slightly Off Axis Sketch” After Importing • Text Style Converted To Revit

39. Navigating through the Export Process to Match AEC CAD Standards Checklist In Revit Before Exporting • Mapping Of Layers/Colors (Export Layers Txt File) • File > Export…Export Options • Miscellaneous • Text On Titleblock Should Be Set To Transparent • Had Issue With Section Headers Hatching – Needed To Edit Block Symbol

40. Navigating through the Export Process to Match AEC CAD Standards 3.0 Checklist In AutoCAD 2007 After Exporting • Linetype Scale – Scale Up X92 For 1/8”=1’-0” • Fill Patterns And Masking Regions Were Solid Hatch In AutoCAD Files • DWG File Naming Convention To Match AEC CAD Standards

41. Revit To 3DS Max Rendering Process • Exported Revit Discipline Models • Detach From Central • Remove All Links • Export 3d View To AutoCAD • In 3DS Max: • Linked In The Architectural .DWG • Linked In Each Other Discipline .DWG • The Model Only Edited If Needed For A Rendered View • Materials & Lights Added • VRAY – Rendering Engine
