The last official release of a steel version of the bridge rating software that WSDOT uses was Bridg97. That software offers WSDOT’s and FHWA’s standard rating systems, both based on Load Factor Rating (LFR). Unfortunately, it depends on software packages that have become obsolete. WSDOT has also adapted a concrete version of Bridg (last official release was Bridg10), whose updated interface is platform independent. Steel Bridg shares large portions of the user interface with concrete Bridg, and so parallel development has been dedicated to porting the steel-specific user interface into a new, platform-independent steel Bridg version, although it still has technical limitations related to WSDOT and FHWA standard rating, as well as graphics capabilities. This project is working to further upgrade the new steel Bridg by porting the load module and LRFR-specific extensions from the concrete Bridg to the improved steel Bridg software and otherwise utilizing the existing features of Bridg97.
