1 BIM UNDERSTANDING THE PROCESS The State of the Art Tool in Design and Construction SPONSORED BY SAME, DC POST IN ASSOCIATION WITH ACEC M/W

2 Insanity: doing the same thing over and over again and expecting different results. Albert Einstein

3 Definition of BIM Building Information Modeling (BIM): 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 buildingdesign design and construction. The process produces the Building Information Model, which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components.

4 History of Methods of Production 70s 80s 90s Building Lifecycle Mgt. Building Information Modeling Objects Tracing Paper Layered Production Computer Aided Drafting Manual Methods CAD Object Oriented CAD Centralized, Integrated Databases Future Technologies

5 Central Database vs Federated File Structure Database Built on a database platform that allows the creation of parametric and information rich objects. Parametric modeling dependencies are automatically updated whenever changes are made and are bi directional. Sequential workflow between modeling and documentation Fully parametric Bi directional Central database file structure Federated Built on a CAD based platform. Uses a federated file structure to develop a composite model to produce construction documents. Parallel workflow between modeling and documentation Limited parametric Not bi directional Federated file structure

6 Federated Workflow 3D 2D Optional Project Master Model Extraction Files Geometry Files Project Model Struct Arch Struct Arch Sheet Drawing Files Discipline Master Models Struct Arch Mech Mech Mech Design Models Schedules and Tables

12 BIM in the Design Process BIM Process Workflow Modelers vs. Drafters Designing in the Model Modeling effort over the life of the project Increased modeling time up front compared to CAD» DD phase drawings may be lighter Frontend coordination» 3D coordination» Conflict resolutions

13 BIM in the Design Process BIM Process Parametric documentation Each element has parameters Can organize/query parameters in schedules Previous methods Symbols and information stored separately Information duplicated deach time it is used Parameterized Symbols, 3D geometry, and information stored together Can locate 3D geometry by searching information and vice versa Information stored once can be referenced many times

14 BIM in the Design Process Benefits to the Design Parameters contained within model Data in one location reduces discrepancies on drawings Calculated loads and schedules are automatically updated to reflect changes on plans and vice versa Panel schedules Device counts Equipment schedules

15 BIM in the Design Process Benefits to the Design Visualization enabling design Verify vertical clearances and mounting heights Determine floor box depths Verify design of systems in 3D

16 BIM in the Design Process Coordination of Trades 3D coordination is enabled Design around other elements in the model Can turn on/off various trades as needed during design Design information is shared Same model elements used by all trades Can implement automatic notifications of changes

17 BIM in the Design Process Coordination of Trades Coordination tools Walk/fly through Shared Schedules Custom applications Clash detection

18 BIM in the Design Process Design Analysis and Verification Visualization on plans Lighting photometric calculations Loads (W/sf) Fire ratings of walls Run calculations and verifications using the model s database Automate system diagrams and calculations

19 BIM in the Design Process Design Analysis and Verification Shared model for energy and solar analysis

20 Analyzing the Model Design Analysis and Verification: Shared model for photometric analysis

21 BIM in the Design Process Design Analysis and Verification Future shared model for computational fluid dynamics (CFD) analysis Perimeter Study Particle Trace Air Velocity Profile Temperature Profile

22 BIM in the Design Process Documentation Final product Construction drawings Model Parametric benefits Global changes Can adjust project standards (element symbols, line weights, text heights, general sheet notes, keynotes, revision names/numbers, etc. ) Vs. per sheet as with CAD projects Issued/revision i history Sheet lists

23 BIM in the Design Process Drawbacks and Limitations Linked models (coordination and data sharing limitations) i i Software and network limitations Complex software requires training i Evolving technology More coordination time in the design phase is expected and required by clients GIGO (Garbage in, garbage out) applies
