According to a survey by the joint BIM committee of the American Institute of Architects and Associated General Contractors of America, 74% of the 1,266 respondents said they\'re using 3-D digital modeling at some level.

The Merry Road to BIM

By Jeff Yoders, August 11, 2006,Building Design and Construction

  • Trends in BIM
  • Frank Gehry

His work includes the Experience Music Project (Seattle), the Guggenheim Museum Bilbao (Spain), and the Walt Disney Concert Hall (Los Angeles); Constructed by Mortenson Construction.

  • GSA: US General Services of Administration

The GSA has even taken the extreme step of mandating the use of IFC-based BIM and believes that BIM adoption should not be driven by cost savings alone, but for its many other benefits such as the ability to explore different engineering systems, perform energy analysis for LEED certification, derive specifications automatically, and eventually eliminate the use of paper and paper-based processes

Review of Literature:

Case Study

  • SHSU Academic Building 5 @ Huntsville, Texas:
  • Designed by WHR Architects
  • Constructed by SpawGlass Construction
  • Project Start Date: 15 May 2007
  • Project End Date: 26 September 2008
  • Project Duration: 16 Months

The project is a 4 story high building with a basement and penthouse level

Research Case:

slide8

SpawGlass Construction

  • Expected Benefits from BIM
  • Integrate Time schedule: 4D
  • Detect Design Conflicts
  • Update the 4D model as the project progresses
  • A need for dynamically integrated 4D model
  • Sub-Contractor Co-ordination.
  • Parts of BIM not tested
  • Quantity take-offs
  • Resource allocation: Man-hours, methods and materials
  • Cost allocation across project duration
  • Facility Management

slide10

Model Transfer

  • Expected Transfer using IFC extension file
  • Convert Revit file to IFC file
  • Open IFC file in Constructor 2007
  • Add schedule in constructor
  • Create the sequencing file in Presenter 2007
  • Issues encountered
  • IFC Conversion is a time-consuming process
  • Unexpected scaling of elements in Constructor

Case Study: SHSU Academic Building 5

slide11

Challenges

  • Creation of second BIM model with necessary details to integrate all scheduling activities.

slide12

Challenges

  • Creation of second BIM model with necessary details to integrate all scheduling activities.

slide13

Challenges

  • Creation of second BIM model with necessary details to integrate all scheduling activities.

Case Study: SHSU Academic Building 5

slide14

Challenges

  • Scheduling to reflect updated schedule
  • Linear Scheduling using Construction Simulation File

No option for predecessor / successors relationship logic

Case Study: SHSU Academic Building 5

slide15

Challenges

  • Scheduling to reflect updated schedule
  • Dynamic Schedule using Recipe Menu
  • STEPS INVOLVED
  • Start project in Estimator: Establish Project Database
  • Assign Recipes to Building elements in Constructor
  • Define the Work Breakdown Structure
  • Assign Construction Zones
  • Add Task Durations in preferred scheduling software
  • Export the 4D model to Presenter

Result:

A dynamic scheduling file made from scratch using Constructor 2007

Disadvantage:

No scope to dynamically connect an already existing schedule using Constructor

Case Study: SHSU Academic Building 5

slide16

Navisworks – (Currently under tests)

  • Scheduling to reflect updated schedule
  • Dynamic Schedule using Recipe Menu
  • STEPS INVOLVED
  • Convert Constructor/Revit file to Navisworks file format
  • Link an already existing schedule to Navisworks
  • Assign building elements to task components
  • Play real time-space interactive animation file

Result:

A dynamic scheduling file made from existing schedule. Contractor need not change traditional ways of conducting business

Disadvantage:

Navisworks does not let the user draw additional components. One needs to use Revit+Navisworks OR Constructor+Navisworks.

Work to be done

Phase 1: Modeling of Architectural/ Structural Elements

Phase 2: Test Scheduling Connectivity using Constructor/ Revit

Phase 3: Test Scheduling Connectivity using Navisworks

Phase 4: Modeling and scheduling of MEP elements

Phase 5: FinalReports
