Bentley Subsurface Utility Engineering
3D modeling of all underground utilities
Including gravity networks
Clash Detection

• Stored (usually) in DGNLIB
• Two new types (Conduit and Node)
• Specifically defines function (Comm, Electric, Gas, Petrol, Storm Water, Thermal, Waste Water, Water)
Feature Definitions

Feature Definitions Define Presentation
• Work similar to road/site/terrain feature definitions
• Link to element templates for symbology
• Utility nodes require two 3D templates.
• Cells are used very heavily in the element templates.
– 2D cells for plan
– 3D cells for 3D model

• Define shape of the conduit
• Includes a table of size to reduce maintenance effort.
Conduit Feature Defintions
8 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
• Has 2 element templates (cells) to define 3D. One points to a top element template and one for the bottom.
• Has 1 element template (cell) to define 2D plan shape.

Place Node and Place Link
• Place Node command allows creation of new nodes
• Place Link command creates conduits between nodes
• Feature Definition to describe presentation and function.

Creating New FeaturesExtract Utility from Graphics Using Selection Set Method
19 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
Extract Utility From Graphics Command
• Modeled after the Terrain Model from Graphics command.
• Uses graphics from any source.
• Elevations from terrain model or from 3D element.– Terrain Model – graphic is draped
at specified depth
– Element – if the graphic is 3D then user has option of using the elevations of the graphic vertices plus optional vertical offset.
• Use selection set or pick during command prompts

Creating New FeaturesExtract Utility from Graphics Using Utility Filter Method
23 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
• New Utility Filter type similar to Terrain Filters.
Utility Filter Manager

Proposed Utility With TrenchExtract Utility From Graphics Command
26 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
Utility with Trench
• Common use cases:
– Relocation of utilities.
– Modeling of pipe trench for quantities.
– Define a soft clash envelope
• Use selection or filter method
27 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
Trench Template in the Feature Definition
• Conduit Feature Definitions include a property for trench template.
• Which is an OpenRoads corridor design template

Model BuilderLink to External Data Sources
31 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
Model Builder
• Connects to any data source, including:– SHP
– XLS
– TXT, CSV
– Oracle Spatial
• Geospatial sources are preferred.
• Creates 2 way link for import, export and update
32 | WWW.BENTLEY.COM | © 2016 Bentley Systems, Incorporated
Why Are Geospatial Sources Preferred ?
• Geospatial data sources (such as SHP or Oracle Spatial) are preferred because they contain X,Y,Z coordinates on all vertices in addition to node connectivity information.
• Without this geospatial data, you must break line strings into simple lines to maintain fidelity in data.
– Of course, some data (such as gravity networks) are innately single line connections.

Conflict Detection
• Uses same engine as Bentley Navigator Clash Detection.
• Interface is similar.
• Adds new capabilities targeted at OpenRoads Utilities workflows.
