What s Happening in (A)EC? Bridge Information Modeling: Towards BIM/BrIM for the Bridge Lifecycle Stuart S. Chen, Ph.D., P.E. Dept. of Civil, Structural, and Environmental Engineering University at Buffalo Outline Quincy Ave As-Built Case Study Bridge: Quincy Ave BrIM: What and Why; Potential Benefits Glimpses of Streamlined Workflows Summary & Results Acknowledgements Bridge Information Modeling (BrIM): What/Why? Parametric 3D Product Modeling ( yet not independent from Process Modeling) Leveraging of automation and communication technologies for managing bridges through h their lifecycle Fluid and seamless electronic data exchange, management and access Improved communication of information to efficiently manage bridge related data among stakeholders (design, construction, operations and lifecycle asset management) A View of the Life Cycle Process 1
Project Background Piecemeal Progress in the Industry Parametric design tools and Trans omit detailing for fabrication and construction 3D pre-cast concrete modeling tools are not (yet) bridge-oriented Bridge inspection or design/rating (e.g.) apps each require their own data (re)entry 3D geometry created (e.g.) for visualization is not also leveraged for fabrication & construction Develop a prototype integrated system illustrating data exchanges and applications Address entire bridge life cycle Overview of Project Vision Utilize 3-D bridge information modeling (BrIM) as a technology to accelerate bridge project delivery and enhance life cycle management Demonstrate the viability, efficiencies and benefits of the integrated bridge project delivery and life cycle management concept Steel Alternate Information Workflow OPERATION Operated Bridge Rating Data Table Fabrication & Manufacturing 3D Model & CNC File Constructed Bridge Construction Scheduling 4D Model Diagram CONSTRUCTION InRoads Highway Geometry Data TXT / Opis Superstructure design Virtis Pontis Estimating Link Cost Estimating & Bidding MS Project Project Scheduling BrIM DATA POOL LINKAGE TYPE / FORMAT BRIDGEWare (Virtis) BRIDGEWare API Tekla or Geopak Rebar Tekla (4D) MS Project MathCad Preliminary Design SAP2000 Seismic Analysis TXT TEKLA 3D Model 4D (Construction Scheduling) Virtis Rating / / Pontis Maintenance Opis Virtis BrIM Data Pool Opis Pontis BARS/LARS Superload INVOLVED SOFTWARE/ TOOLS APPLICATIONS PRESENTATION TYPE OF MODEL / DATA PRODUCTS MANAGEMENT Data Table Programming Maintained Bridge BRIDGEWare API BRIDGEWare (Pontis) Data Table & Diagram Reporting / NBI Various 3D Model Architecture Tekla Leap MathCAD 3D Model 2D Drawing Preliminary Design Designed Bridge DESIGN METHOD OF DATA EXCHANGE TXT TEXT FILE EXTENSIBLE MARKUP LANGUAGE VBA VISUAL BASIC FOR APPLICATIONS COMMA SEPARATED VALUES BARS/LARS AASHTOWARE AND BENTLEY SOFTWARE Routing & Permitting Concrete Alternate InRoads Highway Geometry Data Information Workflow / Cost Estimating & Opis Bidding Superstructure design Virtis Pontis Estimating Link MS Project Project Scheduling Benefits: In general, the benefits of an integrated system come from accomplishing tasks better, faster and more economically.

Preliminary Design Fundamental Principles The 3D centric approach conceptually boils down to two distinct principles that must be enforced consistently and according to appropriate standards: Nobody drafts anything (model it in parametrically in 3D instead). Enter each given data entry item only once. Thus: Drawings, if needed, can be generated from the 3D model whenever possible, and Electronic data exchange is required between current islands of automation (a.k.a. stovepipes ).
