Bentley Subsurface Utility Engineering

3D modeling of all underground utilities

Including gravity networks

Clash Detection


Utility Feature Definitions


• 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


• 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.

Node Feature Definitions

Import Drainage NetworksGEOPAK Drainage, InRoads S&S, MX Drainage

StormCAD, CivilStorm, SewerCAD, SewerGEMS

WaterCAD, WaterGEMS


Import from Other Formats

• Import from:

– GEOPAK Drainage

– InRoads S&S

– MX Drainage

• The following products by way of SHP file • StormCAD

• CivilStorm

• SewerCAD

• SewerGEMS

• WaterCAD

• WaterGEMS


Importing from Other Applications


Create and Edit FeaturesNode and Link Networks such as Storm/Sanitary


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.


Editing Subsurface Utility Data


Create New Node and Link Features


Editing


Creating New FeaturesExtract Utility from Graphics Using Selection Set Method


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


Extract from Graphics (2D)


Creating New FeaturesExtract Utility from Graphics Using Utility Filter Method


• New Utility Filter type similar to Terrain Filters.

Utility Filter Manager


Proposed Utility With TrenchExtract Utility From Graphics Command


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


Trench Template in the Feature Definition

• Conduit Feature Definitions include a property for trench template.

• Which is an OpenRoads corridor design template


Proposed Utility With Trench


Model BuilderLink to External Data Sources


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


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.


Model Builder


Conflict Detection


Conflict Detection

• Uses same engine as Bentley Navigator Clash Detection.

• Interface is similar.

• Adds new capabilities targeted at OpenRoads Utilities workflows.


Conflict Detection Between Utilities
