Bentley Subsurface Engineering Solution

Bentley Subsurface Utility Engineering

Subsurface utility information is a critical issue with transportation projects. Having incorrect or incomplete data associated with underground utilities can increase project costs and potentially compromise safety and the environment. Our Subsurface Engineering solution delivers 3D design, modeling, and analysis that enables you to easily integrate and share subsurface designs and associated data during all project phases.
Using our Subsurface Engineering solution, you can integrate 3D design, surveying, and geospatial data into a unified modeling and information management environment. This process assures better oversight and understanding of subsurface utility systems. You can optimize your overall design without compromising existing infrastructure.

Our solution helps you maintain a relationship between your existing CAD data and various GIS data sources. You can utilize a two-way information link for extracting and posting data. This integration allows you to optimize underground civil and utility designs and then post back updated 3D civil design data to your GIS data source. You are ensured that as-built project data is exported to the database to continually improve the quality of your underground utilities information.


Perform clash detection

  • Mitigate risk of building in utility-congested area by knowing where existing subsurface utilities are located. Perform conflict analysis of proposed changes to save time, eliminate building errors, and reduce project costs. View clashes in 3D or in table format.

Produce 3D subsurface utility models

  • Create 3D models automatically from survey information, CAD artifacts, GIS data, Excel spreadsheets, Oracle databases, and other industry-standard sources of information.

Resolve subsurface utility clashes

  • ​View conflicts in the 3D model or run a conflict detection report to identify all subsurface utility clashes. The errors are marked with a conflict node and stored in a database so you can easily query and resolve clashes to mitigate potential construction errors.
