Abstract This project was undertaken to investigate alternative Bridge Information Modeling standards. The process developed is called OpenBrIM. OpenBrIM is an alternative method for exchanging bridge information modeling data between different application platforms, organizations, and users. It is a community driven, free, open, on-cloud information modeling system designed for the bridge industry. With OpenBrIM, there’s one central data repository from which all participants operate. Participants are allowed to access information from and to contribute information into the repository. For this project, approximately 30 standard bridge component objects were developed. The OpenBrIM concept uses a standard XML data format to describe dimensions and other data parameters for bridge components. Bridge component library objects are defined parametrically, allowing repeated use for similar components by varying the geometric and/or physical property data. Common data can be defined globally within a project and automatically update all affected objects. In the future, new standards will be developed by the bridge community – the actual users of the information with the most knowledge about various bridge components. 17. Key Words 18.
