10 Definitions BIM Building Information Modeling (BIM) is the process of generating and managing building data during its life cycle. Typically it uses threedimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. BIM encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components. 7

11 Definitions BIM Is the digital worlds example of the initiation, conceptualization, realization and managing of a building. 8

12 BIM Assisting in LCI Goals LCIGoals Maximizes value delivered to the customer while minimizing waste. EPA 2003 estimated C&D waste of170 million tons that s 3.2 pounds per capita per day(pcd) Previously calculated in 1996 as 2.8 pcd 9

13 BIM Assisting in LCI Goals LCIGoals Maximizes value delivered to the customer while minimizing waste. Manufacturing process/system. 10

14 BIM Assisting in LCI Goals BIM Design and Construction process/system. 11

15 BIM Assisting in LCI Goals BIM Is the digital worlds example of the initiation, conceptualization, realization and managing of a building. BIM Is a tool which allowsfor the digital prototyping of a project. It s intent is to be a repository of all pertinent project information of which access is readily available. Geometric Information Readilyaccessible depending upon phase Non-Geometric Information Some areas accessible, most not Analysis informationnot always transferable 12

16 Removing Redundancy NIST 2004 Report estimates 15.4 Billion Dollarsin annual interoperability cost. BIM can do only so much.. Contract development will assist in motivation. IPD, Design Build, Design Assist. Evidence based design will also have a hand in it 13

17 IPD/Design Build Removing Redundancy Design Assist Approach Revit MEP CAD Duct CAM Duct Convert Validated Geometric Information into AutoCAD and then Tag it with Software Specific Information for Fabrication 14

18 Removing Redundancy IPD/Design Assist Approach Design Build Revit Structural DATA SDS/2 FABRICATION In early phases of Design (end of SD), Structural Model is shared Communication Continues with Fabricator Fabricator Model shared with Design and Construction Team 15

19 Moving more field work to fabrication work. More and more examples of this happening in Mechanical and Electrical Trades. Trades that seem very efficient are benefitting from BIM. Architectural Precast Concrete Reducing Waste Study from Georgia Institute of Technology March 26 th 2008 For a 20 story panelized building found that BIM was as much as 58%more efficient in workflow compared to 2D (traditional) methods. 16

20 Reducing Waste More Efficient Designs. Provides Information at Concept Stage 17

21 Reducing Waste More Efficient Designs. Provides Information at Concept Stage Energy Usage Total Energy Usage Intensity Heat Load Renewable Resource Potential Analysis of Monthly Heating Load by Contributor 18

22 Green Building Studio Reducing Waste 19

23 Ecotect Reducing Waste Acoustic Solar and Shadow Tracking 20

24 Reducing Waste 21

25 Natural Ventilation Analysis Reducing Waste Performance Verification using CFD Analysis Ceiling shape studies and general air flow using Fluent from ANSYS Airpak Section through Large Space with Sloped Ceiling Section through Large Space with No Ceiling 22

26 Mining BIM Quantity Takeoff Solidifying Cost Queries the Database Quantifies Objects Update as Necessary 23

27 Information Rich Model Available to Owner Whose is Driving it now More Owners are now demanding BIM on Projects Model Progression Specification AIA E202 Contractors Are progressing very fast. Scheduling / Conflict Resolution Cost Model A/E Design Simulations Quicker Decisions 24

28 Whose Model??? Design Team Information Rich Model Available to Owner Construction Team Combination or Is it Specially Focused Model 25
