Project BackgroundProject Background

Emphasis of Current Efforts

• Cost-Effective Use of Prefabrication Techniques for Bridge Components

• Advanced Materials Technologies, such as Self Consolidated Concrete

• Construction Methods, e.g. Stage Construction, Use of SPMTs and Incremental Launching for Bridge Superstructures

Project BackgroundProject BackgroundWhat is Needed

• “Fundamental Re-Thinking” of the Antiquated Processes that are still being used to Deliver Bridge Projects

We are Nearing the End of an Era

• Relied on “Paper” for Centuries, as a Primary Representation for Engineering and Construction

• Only Industry Producing 3D Products Using 2D Drawings


Other Industry Initiatives

• Building and Other Industries (Auto, Aerospace and Marine) have Documented Reduced Costs, Faster Delivery and Improved Quality Resulting from 3D Based Integrated Design and Manufacturing Processes.

• Recent Examples GM Plants, Denver Museum, Queen Mary

2

Queen Mary 2Queen Mary 2

• Both require use of Building Information Models and a division of the project into phases

1. Transitional document for those unaccustomed to IPD

2. Single purpose entity, offering a fully integrated way to deliver a building

(Excerpts from “AIA Issues New Docs For Integrated Delivery”, by Nadine M. Post, ENR.com)

• MTA NYCTA implementing BIM on all projects by 2009.

American Institute of Architects (AIA): American Institute of Architects (AIA): NewNew model agreements for integrated project model agreements for integrated project delivery (IPD)delivery (IPD)

Piecemeal Progress in the Industry

• Parametric Design Tools and TransXML 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., Visualization, Structural Analysis) is not also Leveraged for Fabrication & Construction, or Management Purposes

• Where Electronic Data Exchange is Pursued, only Pieces of the Overall Workflow are Involved


• FHWA International Review Tour 1999

- Prevalent CAD/CAM in Europe, Japan

• FHWA Workshop 2001: “Computer Integrated Steel Bridge Design and Construction: Expanding Automation”

Established a Roadmap for Integrating Steel Bridge Design-through-Construction Processes

and for Advancing the State-of-the-Art Practice in Steel Bridge Manufacturing Automation and Productivity


“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 Structures

Resolution (2005) FHWA Project: DTFH61-06-D-00037


2D CAD provides an Electronic “drawing board”

3D CAD enables a parametric model

2D Drawings contain the information

3D model contains the info; drawings are only reports

2D Drawings human-readable; separate manual data entry is required for analysis

3D model is computer-readable, such that direct analyses are possible

Coordination is difficult; information is scattered among different drawings and specifications clauses

Coordination is automatic: 3D model is the single source for all product information

Manual checking Automated checking

No support for production Potentially full support for production (via CNC codes etc.)

2D vs. 3D2D vs. 3D

What This Is AboutWhat This Is About

• Develop a Prototype Integrated System Illustrating the Data Exchanges and Applications

• Addresses 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 (POC)

Overview of Project VisionOverview of Project Vision

• A Large and Complex Project

• Relates Many Data Exchanges and Stakeholders

• Involves Development of a Prototype - Not Production - Software Linking Appropriate Existing Commercial Software that Demonstrates a Viable Integrated System for Bridge Project Delivery and Life Cycle Management

Project ScopeProject Scope

• Develop integration and linking software

• Demonstrate utility of an integrated approach

• Promote benefits and efficiencies of this approach

• Develop and conduct one-half and two day workshops

• Make presentations to illustrate use of the system for concrete and steel bridges

Project ObjectivesProject Objectives

• Generate a 3D Architectural Blueprint for Integrating Various Phases into the Automated Processes

• Significantly Improved 2D Design Drawings, as well as Construction Drawings, in Conjunction with Life Cycle Management Through Automation
