Review of Literature:  Trends in BIM  Frank Gehry 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 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

Research Case:  Case Study  SHSU Academic Building 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

Case Study: SHSU Academic Building 5  SpawGlass Construction  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.  Expected Benefits from BIM  Parts of BIM not tested  Quantity take-offs  Resource allocation: Man-hours, methods and materials  Cost allocation across project duration  Facility Management

Case Study: SHSU Academic Building 5  Constructor 2007 Modeling Interface Estimating Interface Scheduling and Generating reports Plays a 5D real time- space file. Cost reports

Case Study: SHSU Academic Building 5  Model Transfer  Convert Revit file to IFC file  Open IFC file in Constructor 2007  Add schedule in constructor  Create the sequencing file in Presenter 2007  Expected Transfer using IFC extension file  Issues encountered  IFC Conversion is a time-consuming process  Unexpected scaling of elements in Constructor

Case Study: SHSU Academic Building 5  Challenges  Creation of second BIM model with necessary details to integrate all scheduling activities.

Case Study: SHSU Academic Building 5  Challenges  Creation of second BIM model with necessary details to integrate all scheduling activities.

Case Study: SHSU Academic Building 5  Challenges  Scheduling to reflect updated schedule No option for predecessor / successors relationship logic  Linear Scheduling using Construction Simulation File

Case Study: SHSU Academic Building 5  Challenges  Scheduling to reflect updated schedule  STEPS INVOLVED 1.Start project in Estimator: Establish Project Database 2.Assign Recipes to Building elements in Constructor 3.Define the Work Breakdown Structure 4.Assign Construction Zones 5.Add Task Durations in preferred scheduling software 6.Export the 4D model to Presenter  Dynamic Schedule using Recipe Menu 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  Navisworks – (Currently under tests)  Scheduling to reflect updated schedule  STEPS INVOLVED 1.Convert Constructor/Revit file to Navisworks file format 2.Link an already existing schedule to Navisworks 3.Assign building elements to task components 4.Play real time-space interactive animation file  Dynamic Schedule using Recipe Menu 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.

Case Study: SHSU Academic Building 5  BIM issues identified so far.

MISSING END BEARING FOR BEAM.

BEAM LOCATION INCORRECT

Clarify detail A6 on A 301. Is there a concrete section behind the MS beam ? DRAWING INFORMATION CONFLICTS

Additional Details are required to construct the glass canopy East canopy DIMENSIONS MISSING

Case Study: SHSU Academic Building 5  Work to be done 1.Phase 1: Modeling of Architectural/ Structural Elements 2.Phase 2: Test Scheduling Connectivity using Constructor/ Revit 3.Phase 3: Test Scheduling Connectivity using Navisworks 4.Phase 4: Modeling and scheduling of MEP elements 5.Phase 5: Final Reports
