Project BackgroundProject Background

Focus of Current Efforts

• Speed-Up Bridge Construction Activities

• Simultaneously Enhance the Quality andDurability of Bridges Being Constructed


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


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


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


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


• FHWA International Review Tour 1999

- Prevalent CAD/CAM in Europe, Japan

• FHWA Workshop 2001: “ComputerIntegrated Steel Bridge Design andConstruction: Expanding Automation”

Established a Roadmap for Integrating SteelBridge Design-through-Construction Processesand for Advancing the State-of-the-Art Practicein Steel Bridge Manufacturing Automation andProductivity


“Theme Areas” Progress:

• 3D Modeling & Electronic Info. Transfer:NCHRP 20-07 Task 149 Project (Completed Nov. 2003)

• Standardized Specs and Approval Processes:NSBA/AASHTO Collaboration

• Standardized Design Details:NSBA/ AASHTO Collaboration

• Showcase of Benefits of Automation:AASHTO Subcommittee on Bridges and StructuresResolution (2005)

FHWA Project: DTFH61-06-D-00037


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”

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


• 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
