What is New & Changed?

LEAP Bridge Concrete CONNECT Edition v16.00.00.24 is the first consolidated version of LEAP Bridge Enterprise, plus all LEAP standalone products including CONSPAN, CONBOX, RC-PIER, and GEOMATH. It incorporates Bentley CONNECT which helps you produce better designs by facilitating collaboration, interoperability, standardization and skills development. For an organization and enterprise, CONNECT provides greater insight and control over project design, deliverables and the people working on them. To learn how CONNECT will benefit you and your projects please read this

Following new features are available in this LEAP Bridge Concrete release.

  • A true one package for everyday concrete bridge design. Brand names of LEAP Bridge standalone products ar replaced by more generic module names. Those modules are:
    • Bridge Parametric Layout under the Geometry tab
    • Precast/Prestressed Girder and CIP RC/PT Girder under SuperStructure tab, and
    • Substructure under SubStructure tab
  • One file type.

Only one file type (*.lbc) is used for saving the entire project information. The project may consist of the full bridge model or only the SuperStructure or SubStructure components.

  • Compatible with old LEAP files.

LEAP Bridge Concrete can open the previous LEAP files (file formats such as *.xml, *.csl, *.cbx, *.rcp, and *.gmd)

  • New routine to open/save project files.

All files, new or existing, should be opened in the main LEAP Bridge Concrete console. However, you may save the files either from the main console, or from the SuperStructure or SubStructure modules.

  • One add-on tool.

Spliced Girder design tool (previously named LEAP CONSPLICE) is now included in LEAP Bridge Concrete. Please note the Spliced Girder tool is stand-alone and is not integrated with LEAP Bridge Concrete.

  • File sharing and management in ProjectWise.

LEAP Bridge files can now be shared and managed in ProjectWise thru LEAP Bridge Concrete.

  • Connected to Bentley OpenBridge Modeler.

Concrete bridge models created in the OpenBridge Modeler can be brought into LEAP Bridge Concrete for analysis and design.

Apart from the changes to LEAP Bridge Concrete listed above, the main routines of modeling, analyzing, and designing bridges remains the same.

This release incorporates the following enhancements and bug fixes.


  • Added the automatic calculations of the Deck Offset for asymmetric layout of bridge superstructure and substructure when the bridge models are generated in OpenBridge Modeler. Previously, users needed to manually input the Deck Offset.
  • One-way connection from OpenBridge Modeler to LEAP Bridge Concrete
  • Added an option to consider Tendons being transformed at the same stage when they are added in the Spliced Girder module.
  • Exposed the height and center of gravity for both girder and composite sections in Girder Properties window in the Spliced Girder module.
  • Removed minimum height limit for pier cap.
  • Added end block and blister design for post-tensioning box girder bridges for India market.


Bug fixes:

  • Precast/Prestressed Girder module (formerly called CONSAPN)
    • Beam layout with flared girder changed unexpectedly after Cross Section dialog was opened and closed.
    • Small variations in the beam lengths of curved and skewed bridges between LEAP bridge models and models exported to MicroStation.
    • Skew factor was not correctly considered and caused inconsistent change in beam lengths.
    • Interpolation of the fpo was not considered when the critical shear section was within the transfer length of prestressing strand.
    • Haunch kept changing from zero to a different value after the program was closed and reopened.
    • Program crashed after the results of stability analysis were shown.
    • Substructure module (formerly called RC-PIER)
      • Active points of interest were not included in the flexural and shear design reports for the option “Offset from CL of the column” in cap design.
      • Self-weight of pier column was missing in the Analysis reports for both Load Cases and Load Combinations when California option was selected.
      • Failed to report the governing case of soil pressure under spread footing when the minimum soil pressure was negative.
      • Required and provided steel reinforcement was not correctly reported for top and bottom of footing cap for a rare case when all piles were within the projected area of stem wall in the plan view.
      • Program crashed during column design when the option “WS as per FDOT SDG 2.4” was selected.
      • Out of memory error when an old file created by the standalone version was being opened.
    • Spliced Girder module (formerly called CONSPLICE)
      • Pre-tensioned stress was incorrectly included in post-tensioning primary and secondary moment report.


Upgrading from LEAP Bridge Enterprise

  • Follow the on-screen instructions and install the program.
  • During installation, program default libraries will be added under “C:\ProgramData\Bentley\LEAP Bridge Concrete\” folder to comply with Windows standards to eliminate problems with access to users without Admin privileges.
  • The installation program will not overwrite the files already existing in the library folder.
  • If you have customized program libraries, you can move them to the above folder, and set the correct paths in the Library Setup dialog from within LEAP Bridge interface.
