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

Steel-Framed Roof Structure – Combination Membrane/ Sheet Metal Roof

Locker RoomsMilitary Unit Storage Rooms Including Arms Vaults, Mechanical, Electrical And Equipment Rooms

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


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


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)


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

Structural Column Grid Updates

Owning Linked Worksets

Concrete Plan to Prepare for 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


Did Not Really Use Dependant Views

Had To Use Masking Regions As A Polygonal Viewport Clip


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”


Only Copy/Monitored Structural Column Grids And Levels

Section Cuts Apparent In Multiple Plans

MEP Disciplines Could Not Show Arrowhead On Space Tags


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

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

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

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

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
