Building Information Modeling : What, Why, How Building Information Modeling : What, Why, How Presentation Transcript

  • Nancy Yen-wen Cheng Building Information Modeling Nancy Yen-wen Cheng, University of Oregon •  What is BIM? •  Why do we need it? •  How does it work?
  • Nancy Yen-wen Cheng What is BIM?
  • What is BIM? Nancy Yen-wen Cheng A Building Information Model is a virtual object database shared by AEC partners -  connects 3D forms to non-graphic attributes (material properties, cost, scheduling and performance information, etc.) Image courtesy of Revit
  • Consistent Information Nancy Yen-wen Cheng
  • Consistent information reduces miscommunication Nancy Yen-wen Cheng Slide courtesy of IAI North America
  • Benefits throughout the Building Lifecycle Nancy Yen-wen Cheng Timo Hartmann & Martin Fischer, Stanford CIFE, 2008
  • Nancy Yen-wen Cheng Why do we need BIM?
  • Why BIM? Downward Construction Productivity Nancy Yen-wen Cheng 2004 2008 2012 2014 2018 2022 2024 …. Paul Teicholtz
  • Benefits of BIM compared to previous 2D CAD or paper Yen-wen Cheng Nancy •  Better: Coordination and clash detection reduces errors •  Cheaper: Efficiency saves money •  Faster: Minimizes redrawing -- Chuck Eastman, Georgia Tech **
  • Benefits of BIM compared to previous 2D CAD or paper Yen-wen Cheng Nancy •  Better: Coordination and clash detection reduces errors •  Cheaper: Efficiency saves money •  Faster: Minimizes redrawing -- Chuck Eastman, Georgia Tech ArchiCad
  • Why BIM? Islands of Automation in Construction Nancy Yen-wen Cheng Slide courtesy of Matti Hannus, VTT
  • Traditional Design Decisions Nancy Yen-wen Cheng Abili ty Effort Litigation Phase SD DD CDs Construction Time Slide courtesy of Patrick MacLeamy, IAI International
  • Earlier Design Decisions with BIM / IP Nancy Yen-wen Cheng Abili ty Effort Litigation Phase SD DD CDs Construction Time Slide courtesy of Patrick MacLeamy, IAI International
  • Benefits for Sustainability Nancy Yen-wen Cheng Facilitates •  Integrated practice •  More seamless performance modeling •  Post-occupancy monitoring & responsiveness Image courtesy of Turner Construction
  • Sustainability requires integrated practice Nancy Yen-wen Cheng •  More stakeholders involved in design earlier •  Shared risk & rewards: Your success depends of success of others –Michael Hricak •  Cultural Transformation needed. New tools don’t change thinking or processes — The Toyota Way by Jeffrey K. Liker Image courtesy of Green Building Services
  • Integrated Practice Nancy Yen-wen Cheng •  One aspect affects all others. Adding mass for a thermal flywheel effect would have triggered a seismic upgrade. As soon as you did something to the flooring, suddenly it wasn't just that cost, but it was the next cost, the next cost. So that was the early design process: dead end, let's back up, let's go this way, try again." - Mark Heizer, Interface Engineering Diana Fischetti
  • Nancy Yen-wen Cheng How does BIM work?
  • Interoperability Nancy Yen-wen Cheng •  Get the right kind of information to the right people. -- Michael Hricak, USC Image courtesy of Victor Várkonyi, Graphisoft
  • Interoperability Nancy Yen-wen Cheng •  Changes to Architectural design changes Structural view •  Industry Foundation Classes provide a common exchange language (driven by the Building Smart Alliance, formerly International Alliance for Interoperability) Image courtesy of Victor Várkonyi, Graphisoft
  • Level of Detail Nancy Yen-wen Cheng •  Model complexity should support each phase of development Onuma Inc.
  • BIM works at all scales Nancy Yen-wen Cheng Geographic Information Systems (GIS) coordinating with building scale models through GeoSpatial Consorium Image courtesy of Geospatial Consotium, Onuma, Inc., Portland Maps

  • What matters? Nancy Yen-wen Cheng From McGrawHill The Business Value of BIM, SmartMarket Report, 2009, www.bim.construction.com
  • Benefits of BIM Nancy Yen-wen Cheng From McGrawHill The Business Value of BIM, SmartMarket Report, 2009, www.bim.construction.com
  • Benefits of BIM Nancy Yen-wen Cheng Evidence •  20-30% higher productivity in the field •  reduction of Requests for Information (RFI) & Change Orders (CO) by a factor of ten or more, •  higher engagement of all stakeholders (~70% positive in 2007 survey) •  consideration of more design options from more perspectives --Martin Fischer, Stanford Center for Integrated Facility Engineering (CIFE) BIM •  Reduces redundancy & errors •  Provides visual communication •  Facilitates adjustable Form with Performance Onuma, Inc.
  • Summary Nancy Yen-wen Cheng Caveat •  Don’t mistake change for innovation. •  With computers, bad design can happen really fast. — Michael Hricak Slide courtesy of Onuma, Inc.
  • Summary Nancy Yen-wen Cheng nywc@uoregon.edu Sustainable Design requires Integrated Practice –  Engage stakeholders early –  Share risks & rewards BIM supports the full building life-cycle BIM: Building Investigation Model BAM: Building Assembly Model BOOM: Building Operation Optimization Model -- Patrick MacLeamy, HOK Slide courtesy of CH2MHill
