INARNG-AFRC Project Background
Primary Spaces Include:
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 FloorsExterior Masonry Walls Combined With Interior Masonry And Steel Stud/Gyp. Board Partitions

Office AreasClassroomsAn Assembly HallCommercial Kitchen
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
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
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
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

File Linking
3 Main Reasons Why Discipline Models Were Separated Out:
1. Each Discipline Controlled Their Own Drawing Sheet Set
2. Prevented Disciplines “Stepping On Each Other’s Toes” Concerning Element Borrowing And Relinquishing
3. Model Performance Was Controlled Through The Opening And Closing Of Linked File Worksets
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
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
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
File Linking
INARNG-AFRC-DRAWINGINDEX.RVT
Separated Out For Two Reasons:1. Model Performance
2. Architectural Workflow – Allows Specialization Of Task
File Linking
Downfalls Time to Open Project File

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
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
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)
Worksharing and Worksets
Key Project Aspects: Taking Advantage of Closing Worksets
Element Borrowing Was Heavily Used
Making Worksets “Editable” Allows 2 Main Benefits:1. Prevents Anyone Else From Manipulating Elements Tied To That
Workset
2. Revit Does Not Constantly “Ping” The Central File About Who Is Borrowing Elements Of That Workset
Model Performance Checks
**Open/Close** Drafting View
64 Bit Machines To Plot Out Submittals

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

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

Survey User Level Experience Per Discipline (1-5)
Establish Expected/Specific/Realistic Tasks By Team Members In Each Discipline Model (Roles And Responsibilities – Put In BIM Implementation Plan)
Standards Are Key – Templates, Bim Implementation Plan, Organized Details And Content
Acceptance Of Working In Revit And How It Will Be Done On A Project Is Crucial….Everyone Must Be On The Same Page
