Project BackgroundProject Background
Focus of Current Efforts
• Speed-Up Bridge Construction Activities
• Simultaneously Enhance the Quality andDurability of Bridges Being Constructed
Project BackgroundProject Background
Emphasis of Current Efforts
• Cost-Effective Use of Prefabrication Techniquesfor Bridge Components
• Advanced Materials Technologies, such as SelfConsolidated Concrete
• Construction Methods, e.g. Stage Construction,Use of SPMTs and Incremental Launching forBridge Superstructures
Project BackgroundProject Background
What is Needed
• “Fundamental Re-Thinking” of the AntiquatedProcesses that are still being used to DeliverBridge Projects
We are Nearing the End of an Era
• Relied on “Paper” for Centuries, as a PrimaryRepresentation for Engineering and Construction
• Only Industry Producing 3D Products Using 2DDrawings
Project BackgroundProject Background
Other Industry Initiatives
• Building and Other Industries (Auto, Aerospaceand Marine) have Documented Reduced Costs,Faster Delivery and Improved Quality Resultingfrom 3D Based Integrated Design andManufacturing Processes.
• Recent ExamplesGM Plants, Denver Museum, Queen Mary 2
Queen Mary 2Queen Mary 2
• Both require use of Building Information Models and adivision of the project into phases
• Standard contract documents provide two (2) levels ofDesign and Construction integration:
1. Transitional document for those unaccustomed toIPD
2. Single purpose entity, offering a fully integratedway to deliver a building

• MTA NYCT DesignManagers eachselected 1 project in2008 on which to useBIM
• Implementing BIM onall MTA NYCTAprojects by 2009
• BIM used to determinethat the massive FultonStreet Transit Centerproject in New YorkCity could proceed withconstruction while thestation remains open totrains and passengers
* Excerpts from “Doing Business with MTA NYCT” specialsupplement to May 2008 NY Construction Magazine
Piecemeal Progress in the Industry
• Parametric Design Tools and TransXML OmitDetailing for Fabrication and Construction
• 3D Pre-Cast Concrete Modeling Tools are not(yet) Bridge-Oriented
• Bridge Inspection or Design/Rating (e.g.) Appseach Require their own Data (Re)Entry
• 3D Geometry Created (e.g.) Visualization is notalso Leveraged for Fabrication & Construction
Project BackgroundProject Background
Piecemeal Progress in the Industry
• 3D for Structural Analysis is also not Leveragedfor Other Asset Management Purposes Needingsuch 3D Geometry Data
• Even when Electronic Data Exchange isPursued, only Small Pieces of the OverallWorkflow Involved in Bridge Delivery areAddressed
Established a Roadmap for Integrating SteelBridge Design-through-Construction Processesand for Advancing the State-of-the-Art Practicein Steel Bridge Manufacturing Automation andProductivity
• Showcase of Benefits of Automation:AASHTO Subcommittee on Bridges and StructuresResolution (2005)
FHWA Project: DTFH61-06-D-00037
Project BackgroundProject Background
Potentially full support forproduction (via CNC codesetc.)
No support for production
Automated checkingManual checking
Coordination is automatic: 3Dmodel is the single sourcefor all product information
Coordination is difficult;information is scatteredamong different drawingsand specifications clauses
3D model is computer-readable,such that direct analyses arepossible
2D Drawings human-readable;separate manual data entryis required for analysis
3D model contains the info;drawings are only reports
2D Drawings contain theinformation
3D CAD enables a parametricmodel
2D CAD provides an Electronic“drawing board”
2D vs. 3D2D vs. 3D
What This Is AboutWhat This Is About
• Develop a Prototype Integrated SystemIllustrating the Data Exchanges and Applications
• Addresses entire Bridge Life Cycle
• Utilize 3-D Bridge Information Modeling (BrIM) asa Technology to Accelerate Bridge ProjectDelivery and Enhance Life Cycle Management
Overview of Project VisionOverview of Project Vision
• Demonstrate the Viability, Efficiencies and
Benefits of the Integrated Bridge Project Delivery
and Life Cycle Management Concept Through
One-Half-Day and Two-Day Presentations of the
Prototype Integrated System to Stakeholders
Around the Country
Overview of Project VisionOverview of Project Vision
• A Large and Complex Project
• Relates Many Data Exchanges and Stakeholders
• Involves Development of a Prototype - NotProduction - Software Linking AppropriateExisting Commercial Software that Demonstratesa Viable Integrated System for Bridge ProjectDelivery and Life Cycle Management
Project ScopeProject Scope
Project ScopeProject Scope
• Implementation Will Require Initial StakeholderInput, Mechanics for Maintenance, and WillIllustrate Economic Benefits and ImprovedQuality
• Presentations, Seminars, and Other InformationExchanges Address the “StakeholderEngagement and Buy In”
• Develop integration and linking software
• Demonstrate utility of an integrated approach
• Promote benefits and efficiencies of thisapproach
• Develop and conduct one-half and two dayworkshops
• Make presentations to illustrate use of thesystem for concrete and steel bridges
Project ObjectivesProject Objectives
• Generate a 3D Architectural Blueprint forIntegrating Various Phases into theAutomated Processes
• Significantly Improved 2D Design Drawings, aswell as Construction Drawings, in Conjunctionwith Life Cycle Management ThroughAutomation
Project ApproachProject Approach
• Highlight the Benefits of Automation andCommunication Technologies to Achieve RapidCoordinated Bridge Design, Construction andSubsequent Life Cycle Management
• Approach will be Implemented by Performing anIntegrated Set of Overlapping Tasks
Project ApproachProject Approach
• Data Ownership Issues will be Addressed withthe Philosophy Espoused by the AISC Code ofStandard Practice:
The Quality of the Contract Documents is theResponsibility of the Entities that Producethose Documents
