The 'representative' bridge is parametrically modelled in accordance with Figures 2.1(A), 2.1(B),2.1(C), 2.1(D) of the Commonwealth of Pennsylvania Department of Transportation's Software Evaluation for LRFD Refined Analysis of Girder Bridges - 2017. Parametric modelling refers to the relationships among all bridge components in a project that enable the coordination and change management that OpenBrIM Platform provides. These relationships are created in OpenBrIM Library by the engineers.
