Bridge Information Modeling (BrIM): What/Why?

• Parametric 3D Product Modeling (≠ yet not independent from Process Modeling)

• Leveraging of automation and communication t h l i f i b id th htechnologies for managing bridges through 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)

Piecemeal Progress in the Industry

• Parametric design tools and TransXML omit detailing for fabrication and construction

Project BackgroundProject Background

g

• 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 VisionOverview of Project Vision

• Address entire bridge life cycle

• 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

The Conundrum

Electronic Data Transfer/Translation among the various “islands of automation” (stovepipes)automation” (stovepipes)

“If there is an industry - wide standard for electronic data exchange of (life-cycle) bridge data that is non-proprietary, we will gladly write translators for it” – a software solution provider

Commercial Software: Linkage ApproachesCommercial Software: Linkage Approaches

• DLLs (e.g. WSFL – QCONBRIDGE)

• VBA (e.g. Bentley, MS Office (Excel))

• C#/.NET/API (e.g. Tekla, BridgeWare CSI/SAP2000, Bentley BrIM Apps)

• C/MDL (e.g. Bentley)

• CIS/2 (e.g. Fabtrol)

• XML (e.g. Access, MathCad, LEAP, AASHTOWare Opis/Virtis/Pontis)

• IFC (e.g. Timberline Estimating)

• Direct (e.g. SAP – Tekla, EstimatingLink – MSProject, etc.)

Fundamental Principles The 3D – centric approach conceptually boils down

to two distinct principles that must be enforced consistently and according to appropriate standards: N b d d ft thi ( d l it i t i ll i 3D 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”).
