Project BackgroundProject Background

Focus of Current Efforts

• Speed-Up Bridge Construction Activities

• Simultaneously Enhance the Quality andDurability of Bridges Being Constructed

Page 3: Integrated Project Delivery and Life Cycle Msp.bridges.transportation.org/Documents/IntegratedProjectDeliveryandLifeCycle... · Integrated Bridge Project Delivery &Integrated Bridge

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

Page 5: Integrated Project Delivery and Life Cycle Msp.bridges.transportation.org/Documents/IntegratedProjectDeliveryandLifeCycle... · Integrated Bridge Project Delivery &Integrated Bridge

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

• 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

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

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”
