Transcription

1 FHWA Bridge Information Modeling Update Presented by: Mike Bartholomew, P.E. / CH2M HILL for AASHTO Subcommittee on Bridges & Structures T-19 Technical Committee for Software & Technology Saratoga Springs, NY April 20, 2015

2 Topics FHWA Project Vision and Objectives BrIM vs. BIM Technical Review of What s Been Done Open Source Software Application Further Development of BrIM Standards Industry Outreach Program What s Next

3 FHWA Initiative Part of Overall Project DTFH61-11-H Advancing Steel and Concrete Bridge Technology to Improve Infrastructure Performance Task 12 Technical Review and Industry Outreach for Bridge Information Modeling (BrIM) Standards

4 Project Team FHWA Brian Kozy, Ph.D., P.E. Lehigh University Chad Kusko, Ph.D. CH2M HILL Mike Bartholomew, P.E. Other Coordination AASHTO T-19 Scot Becker, P.E. National Institute of Building Sciences Roger Grant Advancement of Bridge Information Modeling Standards using existing Industry Foundation Class (IFC) standards

5 Project Visions FHWA Seeking to promote the use of BrIM as a Technology Advancement to the way the Bridge Community conducts business Vision Exploit Full Potential of Computer Technology by: Transforming Current Practice into Full Digital Delivery

6 Project Objectives Provide Bridge Community with credible, robust digital standards Identify Bridge Component model definitions to develop 3D BrIM models for workhorse bridges Promote Interoperability between various Software Platforms, Project Functions, and Users Encourage Software Vendors to develop translators to automate data transfer in a universally standard format

7 BrIM vs. BIM Building Information Modeling (BIM) is a mature system for Vertical Construction 90% usage in 2014 according to McGraw-Hill Construction Geometric Layout defined by a primarily rectangular Building Grid/Floor Level System BrIM is in early stages and is geared towards Transportation or Horizontal Construction No information on industry usage Geometry is defined by Horizontal Alignments, Vertical Profiles, and Transverse Cross-Slopes

8 Work Previously Completed Also Part of Overall Project DTFH61-11-H Advancing Steel and Concrete Bridge Technology to Improve Infrastructure Performance Task 12 Bridge Data File Protocols for Interoperability and Life Cycle Management State University of New York (SUNY) at Buffalo Stuart Chen, Ph.D., P.E.

9 Work Previously Completed Project Deliverables included: Vol. 1 Implementation Roadmap for BrIM Vol. 2 Information Delivery Manual (IDM) Bridge Life Cycle Process Map Activities Project Stages (e.g. Prelim. Design, Final Design, Fabrication) Disciplines (e.g. Roadway Eng., Structural Eng., Estimating) Exchange Model Definitions Coordination between Project Stages & Disciplines Data Definitions Vol. 3 Model View Definition (MVD) Elements Example bridge models Example bridge component models

10 Current Project Work Extension of work completed by engineering students at SUNY Buffalo Involvement of practicing bridge engineers Identify critical bridge components of workhorse bridges Promote BrIM through Outreach Workshops & Webinars

11 Current Project Work Focus on development of Bridge Component Standards Data definitions Parametric dimensioning Standardized data schema/format Referencing component location/orientation station, offset, elevation, cross-slope Referencing textual data material properties, inspection data Graphical representation in an open source software environment

12 Open Source Software Application OpenBrIM Viewer Red Equation Corp. Uses EXtended Markup Language (XML) Engineering on Cloud Internet Browser based Works on Computers, Tablets, and Mobile Phones Internet Explorer version 11+ Google Chrome Mac OSX Apple IOS iphones and Tablets Android Phones and Tablets Microsoft Phones and Tablets

13 OpenBrIM Viewer v3.0 URL: Anyone can register

14 OpenBrim Viewer Features Geometric Alignment Objects Includes Circular and Spiral Horizontal Curves Parabolic Vertical Curves Crown and Cross-Slope Superelevation Component Objects located by: Alignment Station, Offset, Elevation, and Cross-Slope

15 OpenBrim Viewer Features Component Objects constructed geometrically by: Extruding a cross section object along a line object Lines may be straight or curved to follow alignment Can use a simple circular cross section Defining a planar surface object with a thickness Connecting two planar surface objects to create a volume object

16 Creating Standard Objects Anyone can create a standard BrIM object State DOT s, Consultants, Contractors, Precast Concrete & Steel Fabrication Plants, Suppliers, Software Vendors Software Vendors responsible for developing translators to graphically display and read/write BrIM object data with their application Standards submittals will be subjected to an acceptance process, then stored on a server database maintained by FHWA (or representative) System relies on active bridge industry participation

25 Industry Outreach Workshop

26 IBC Workshop W-5 Bridge Information Modeling, Standardization & Interoperability David L. Lawrence Convention Center Pittsburgh, PA Thursday, June 11 8 AM to noon EDT

27 IBC Workshop W-5 Agenda FHWA Vision and Role Brian Kozy/FHWA Owner Perspective/AASHTO T-19 Scot Becker/WisDOT FHWA Technical BrIM developments to date (OpenBrIM Viewer Demo) Mike Bartholomew/CH2M HILL Audience interaction/roundtable Modeling standards gap analysis and review of IFC Roger Grant/NIBS Discussion and Q&A Lessons learned and future directions of BIM in Steel Industry Luke Faulkner/AISC Lessons learned and future directions of BIM in Concrete Industry Pete Carrato/Bechtel Audience interaction/roundtable

28 What s Next? Soliciting feedback from the Bridge Community 2 nd Workshop being planned in August in Washington, DC Evaluation of OpenBrIM vs. IFC extension of BIM Identify future work, including a management plan for standards storage
