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

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

Definition of BIM  Building Information Modeling (BIM): The process of generating and managing building data during its life cycle. Typically it uses three- dimensional, real-time, dynamic building modeling software to increase productivity in building 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.

Central Database vs Federated File Structure DatabaseFederated 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 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

 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” – Front end coordination » 3D coordination » Conflict resolutions

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 each 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

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

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

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

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

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

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

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

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

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 history  Sheet lists

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