Building Information Modeling (BIM) For Infrastructure

BIM Clearinghouse

The BIM Clearinghouse is an online searchable platform designed to communicate TPF-5(480) research findings and guidance.

Document Library

The BIM Clearinghouse Document Library is a searchable and curated database of reports that contains comprehensive information in support of BIM for Transportation Infrastructure.

Launching in 2024


3D Cell Library

The BIM Clearinghouse 3D Parametric Cell Library is a searchable database of complex elements that are regularly used in designs. The library contains DGN files that contain one or more models, one for each cell. The cells are design models that have the option ‘Can be placed as a cell’ enabled. Cells created in this fashion have the model’s origin as their origin.

Cells are used in 3D modeling in a manner like 2D. You can place a 2D cell in a 3D model and vice-versa. When a 3D cell is placed in a 2D model, it is placed as a Top view orientation. That is, with its X and Y design axes matching that of the 2D model's X and Y design axes.

Data Artifacts

The BIM Clearinghouse Data Artifacts is a searchable database of BIM deployment tools that are used in the development of data models, including: 

  • Terms and Definitions – A glossary of all BIM related terms and definitions.
  • Data Models Catalog – A catalog of information about the data models created in the digital delivery process.
  • Data Assets Catalog – A catalog of information about the data assets captured in the data models.
  • Information Exchanges Catalog – A catalog of information about all the data exchanges between data models and digital workflow process steps.
  • Object Type Library (OTL) – A library of object types that are part of the BIM data model. They are also referred to as “model elements” and the AASHTO JTCEES Model Element Breakdown will be used as the starting point for defining these object types.
  • Data Dictionary – The BIM data dictionary describes the attributes that are captured in a data model corresponding to each of the object types in the model.
