BGS-TxDOT Bridge Geometry System
The TxDOT Bridge Geometry System (BGS) is useful for bridge geometric design. Included in the text output are geometric data and reports that may be imported into various MicroStation design files to include angles, dimensions, elevations, etc. in the bridge plans as needed to accurately fabricate and place the various bridge elements during construction as well as determine bid item quantities during preparation of the PS&E package.
BGS Version 8.1 (a.k.a. v8.1.7, released June 2007) was developed from TxDOT Roadway Design System (RDS) Version 8.0 by removing all non-bridge related RDS commands. The result of these changes was a "scaled down" implementation of RDS that focuses on bridge geometric design. In BGS v8.1 the user could define, and display graphically, geometry points and curves, bridge alignments with templates, superelevations and widenings, and bridge framing, with or without contours, but code supporting RDS functionality strictly employed in roadway design was removed from the RDS source code to yield BGS. BGS v184.108.40.206 was deployed in November 2011 as a technical release to address OS issues with v8.1.7. By November 2011 work was underway on BGS v9.0 building upon the v220.127.116.11 source code. By January 14, 2014 more than 195 distinct changes had been made to BGS v18.104.22.168 including bug fixes, enhancements and modifications to yield development version 9.0.3. In addition to these functional changes, the source code for the BGS component bgs1.exe_which performs all geometric and plotting calculations and output reports_was migrated from the Intel compiler v10 (integrated with VisualStudio 2008) to v11 (integrated with VisualStudio 2013) and a number of modifications were made to the interface program component bgs.exe. The resulting BGS v9.1.5 was released in January 2016 but had to be recalled due to a bug that blocked bearing seat elevations from being included in the formal output listing for certain framing options. The bug-fixed version, BGS v9.1.6 was released in February 2016.
The current draft of the BGS v9.1 User Guide is over 360 pages long. Due to file size and for other reasons it is not deployed directly to the end user's machine but is rather stored on TxDOT_s FTP server. Users can access the guide via a link to it installed in the Bridge Geometry System (BGS) program group. This decoupling of the BGS User Guide from the packaging of the software allows for revision on an as-needed basis throughout the life of BGS v9.1. This BGS User Guide, like the old RDS User Manual, should provide all the information that the user will need to run the software.
An experienced RDS user will be able to begin using BGS immediately. The BGS input data, output computations, reports and CAD plots are the same as produced by RDS when applied to bridge geometric design, notwithstanding the effects on output of numerous bug fixes and enhancements made to BGS since its initial release.See the BGS Support Information document, linked in the same manner as the BGS User Guide, for instructions on how to report bugs and wishes about program functionality or get technical support. Technical support is available to all TxDOT BGS users and any consultant BGS users designing bridges for TxDOT.

released the original Windows version (7.0) in March 2007 and the second phase update (7.1) in July 2008. The HY-8 program has successfully operated on all current "flavors" of the Windows operating
HY-8 7.2 represents a "maintenance phase "of the FHWA's multi-phase culvert hydraulic software upgrade plan. In the future, the plan calls for using a pooled fund effort1 to fund and support incremental
upgrades and additions of features, based on available time, budget, and adoption of new hydraulic practices and techniques.

(http://www.wsdot.wa.gov/eesc/bridge/alternateroute/licenses.htm)
The TxDOT-customized version of PGSuper_ is versatile, user friendly, Windows-based software for the design, analysis, and load rating of multi-span precast-prestressed bridge beams/girders in accordance with the AASHTO LRFD Bridge Design Specifications (thru the 7th Edition, 2014, as modified by the 2015 Interim Revisions) and TxDOT design policies and guidelines. Properties of TxDOT standard I-girders (TxGirders), U beams, Slab beams, Decked Slab beams, Box beams and X-Beams and TxDOT design criteria are included in templates and libraries published by TxDOT on a server accessible via the Internet. Thus, the software is capable of periodically updating the installed templates and libraries with the most current versions published by TxDOT.
Custom defined beam shapes that fit within each family of girder types supported by PGSuper can also be added to a user_s installed copy of the templates, thereby extending the girder shapes that the user can design, analyze and load rate with the program.
The flexural design feature computes the required number and pattern of prestressing strands and the minimum required release and final concrete strengths. Specification checking evaluates girders for compliance with strength, serviceability and detailing criteria. Horizontal and vertical shear design, analysis and load rating is also facilitated.
A variety of results reporting is provided, including exhaustive and comprehensive reports, reports tailored to specific design or analysis features, fabricator optional design evaluation reports and a TxDOT Girder Schedule Report ("TxDOT CAD Output").
Certain functionality of this version of PGSuper has been enhanced over that of the previous release and most known issues/bugs present in the previous release are fixed in this release. For a list of these changes see the PGSuper support Information Document.
