Drainage & Utilities


Create 3D Models from Survey Data


Utility Models from Survey

• “Survey” means anything located in the field and represented graphically after processing.

– Land Survey

– Geophysical methods such as SPAR and GPR

– Paper records reduced to graphics

• Utility profile defined by:

– The survey information (3D graphics)

– Drape on terrain at assumed depth


Utility Models from Survey Data

• Insert Durham Park Extract Graphics Video.


Create 3D Models from External Data Sources


Build Hydraulic and 3D Models from External Sources

• Direct Import from:

– StormCAD, CivilStorm, SewerCAD SewerGEMS (.stsw)

– SWMM V5

– LandXML

– MicroDrainage

– GEOPAK Drainage

– InRoads S&S

– MX Drainage

• Using Model Builder link/import from:

– Microsoft Excel

– Microsoft Access

– Text Files (.csv, .txt)

– ESRI (.shp)

– Bentley Map

Utility Models from GIS

• Make a new recording and augment dataset to retrieve some utilities from SHP.

• Manufacture a SHP file for GAS.


Design New and Relocated Utilities


New Utilities

• For relocation or extension

• Uses same workflows as existing utilities

• Except there is usually an additional step of designing a profile.

• Trench design defined by ITL template.


Automatically Create 3D Models While

Laying out Networks


Layout Drainage Network


Modeling Storm and Sanitary Networks

• Inlets, headwalls and catch basins ruled to OpenRoads geometry and surfaces.

• Pipes ruled to the nodes.

• Multi-pipe profile runs

• Hydraulic properties linked into feature definitions.


Catchments (Drainage Areas)


Layout Catchments


State of the Art Drainage Design

Calculations


Storm/Sanitary Product Functions

• StormCAD – Rational Method storm water design and analysis (HEC 22)

– Included in OpenRoads Designer

• SewerCAD – Gradually varied flow sanitary sewer design and analysis package

• CivilStorm – Storm water management and dynamic modeling

• SewerGEMS – Complete storm and sanitary sewer modeling analysis and design package with geospatial integration. Superset of SewerCAD, CivilStorm and StormCAD.


Peak Flow Hydraulic Analysis/Design

• Included with OpenRoads Designer

• StormCAD GVF calculations engine.

• 3D Model updates with design changes.

• Includes latest HEC-22 methods.


Scenario Manager


Scenario Manager

• Scenario Manager provides unlimited variation of design parameters with complete confidence that known good alternatives can be recalled at any time.


Conflict Detection


Conflict Detection

One of the top benefits of integrated modeling is the ability to run conflict detection and find issues.

This is most commonly done in the case of utilities, but OpenRoads can run conflict detection against any group of objects by identifying their levels or features.


Name: 6-ConflictDetection.mp4


Cross Drains (Culverts)


Culvert Design / Analysis

• Perform Culvert Analysis by flipping the “Is Culvert” switch in properties to True

• Define inlet coefficients on conduit or the end node


Advanced Hydraulic Calcs


SWMM Analysis

• Using EPA SWMM analysis allows validation of a peak flow design

• Network is analyzed for the entire storm event, not just the peak flow.

• Available in CivilStorm and SewerGEMS


Higher Level License Highlights

• SewerCAD– Adds Convex compute engine

– Sewer Loading tools

– And more…

• CivilStorm – Adds Dynamic Wave and SWMM compute engines

– Pond Maker tool

– Compute Storage in network

– Low Impact Development structures (LIDs)

– And more…

• SewerGEMS – All the above and more, such as long term simulations
