BIM / VDC / IPD

How does it provide Advantages and Benefits And What Challenges to Expect

Project Examples

  • Del Norte High School, Poway Unified School District
  • Oceanside High - Performing Arts Center, Oceanside Unified School District

BIM Topic

  • Project scenarios
  • Defining the BIM Process
bim current real world use cd s drawings plans models projects workflows
BIM Current Real World UseCD’s, Drawings, Plans, Models, Projects & Workflows

How are we utilizing BIM and what BIM tools are we using

  • Constructability (clarification, interference detection, )
  • Scheduling Timeliner in Navisworks 4D
  • Quantity Takeoffs 5D
  • LEED Certified Projects

Today’s Tools & Workflows

  • Revit Architectural, Structural, & MEP 2009
  • Navisworks Manage 2009
  • AutoCAD MEP 2009
  • VE – Toolkit
  • USGBC
  • LEED

Planned Future Tools and Possible WorkFlows

  • Autodesk 3Ds Max
  • Innovaya or Quantity Takeoff
  • Integrated Project Delivery

  • Sloped Structure above Space
  • No Section Cuts in Construction Documents
  • How to fit everything into the space had been only conceptualized @ best
  • Mechanical Return Air duct to adjoining space wouldn’t fit across the Supply air duct and between the Suspended ceiling and the pipe batten system.

Coordination

  • Suspended Gyp Board Ceiling
  • Tight Space Requirements
  • Pipe Batten Grid For Production Studio
  • Original Design would not fit

Interference Resolution

  • Space Requirements verified by Model
  • Placement reviewed with Field personnel
  • Pipe Batten Hardware Rep able to visualize space and equipment in relation to structural
  • Navisworks files created for full visualization and communication of the space
  • New Routing and layout per collaborative BIM review effort

  • Three disciplines Modeling the Project in Autodesk Revit
  • Architectural, MEP & Struct.
  • First BIM Project for all Three
  • Architect Self taught in Revit
  • MEP consultant had basic training
  • Structural Consultant had basic training
  • The Challenge BIM to CD’s

Mechanical floor plan that clearly shows the

ducts penetrating the Auditorium Floor Right ?

Overcoming Project Challenges and changing Industry Mindsets
  • BIM Model really does clearly showing the ducts penetrating the Auditorium Floor !

  • The Views
  • Seeing is Believing
  • Graphical communication
  • Viewer for team members
  • Collision detection
  • Time Liner
  • Renderings
  • Presentation
  • Speed
bim as a project approach
BIM as a Project Approach

Utilizing a BIM Workflow on a Project will Naturally bring about

  • Collaboration
  • Responsibility
  • Accountability

With a BIM Workflow and BIM models the focus becomes project focused not CD focused and Drives an integrated Project Delivery Process

  • Mutual Respect and Trust
  • Mutual Benefit and Reward
  • Early Involvement of Key Participants
  • Early Goal Definition
  • Intensified Planning
  • Open Communication
  • Appropriate Technology
  • Organization and Leadership

With a BIM model you can produce your CD’s from the BIM model

and everything matches between the BIM Model and the CD set

bim advantages and benefits leveraging bim for coordination
BIM Advantages and BenefitsLeveraging BIM for Coordination
  • Visualization
    • Coordination and Design / Improved Workflow
