Bentley’s MicroStation Hydraulic Design/Analysis Software

October 17, 2018

Update on SUDA Development from 2017 SUDA Implementation Schedule SUDA/StormCAD Tools ◦ Management Tools Scenarios vs Alternatives (Parent vs Child relationship)◦ CivilStorm – dynamic analysis

Utility Clash Detection

Subsurface Utility Design and Analysis Two components:

1. Hydraulic design and analysis – Storm-sewer StormCad is the hydraulic computational engine

2. Utility Clash Detection

2,762 3D Cells are complete◦ Feature Definitions◦ Element Templates◦ Prototypes (Hydraulic Losses)

Develop Seed File (Template)◦ 3D Cells◦ Feature Definitions◦ Rainfall Data◦ Landuse Coefficients ◦ Hydraulic Losses – Entrance/Exit, Junction losses◦ Scenarios

TxDOT Seed File (“Version 1”) planned completion January 2019.

Geopak Drainage to be phased out in stages

Bentley Phase out Schedule1. Updates will cease in 20192. Bentley support will cease in 20203. GEOPAK will not be available (from Bentley) by

2021-2022

TxDOT Phase out Schedule1. Geopak to be phased out after Open Roads

Designer (summer 2019)2. Exceptions made for projects started in Geopak.

New Training to start with release of SUDA TxDOT seed file in January 2019.◦ Bentley Training ◦ TxDOT Training - Step by step, hands on using

TxDOT workspace, TxDOT Seed file and example corridor

Software Progression Spreadsheets Winstorm◦ Automated Analysis◦ Ease of use◦ Freeware developed by TxDOT

GEOPAK ◦ Incorporated into MicroStation◦ Automated Design and Analysis◦ Plan and Profile sheet

generation with labeling

Incorporated into MicroStation Improved Automated Design and Analysis Plan and Profile sheet generation with labeling 3D models◦ Hydraulic Model tied to 3D Roadway Corridor model

Management Tools◦ Scenario Management

Dynamic Modeling◦ Civil Storm

Great for visualization and presentation 3D Storm-sewer Model Tied to 3D Roadway corridor Model. ◦ Changes made to Roadway vertical and horizontal alignments reflect into

storm sewer model

Introduction of Scenario Management What is a scenario:

A series of “What If” situations for a model, A collection of alternatives

Allows Designer to compare and manage variations in hydraulic properties and attributes

◦ Scenarios are maintained in a single Project file◦ In GEOPAK, to change a model Copy model Edit model (slope change, pipe change, add inlets etc) Re-calculate and review results

◦ Scenario management using inheritance with parent child relationship◦ Biggest Improvement from previous software

Scenarios Alternatives – (Building blocks of Scenarios, Set of

properties) Active Topology (Isolate areas of a network) Physical (elevations, pipe sizes, roughness coeff, etc) Headloss Boundary Condition (Tail Water etc) Rainfall Runoff (Storm Frequencies) Hydrology (hydrologic method) Design (spread width, allowable velocity, cover)

Dynamic Modeling – Unsteady Analysis – Depth and velocity vary with time

at a given location Quantify flood storage, more accurate results Incorporated into SUDA No need to Export/Import

SUDA will not be able to produce and label profiles until TxDOT implements MicroStation Open Roads Designer

Open Roads Designer will not be available until TxDOT implements Windows 10 in summer 2019.

Use GEOPAK on projects with larger systems Use SUDA on projects with smaller systems and cut sheets manually Use SUDA as a preliminary analysis tool

New Rainfall Data –Implementation of Atlas 14 Rainfall depths

Biggest rainfall depth changes are in the50 year and greater return periods.

Add freeboard to HGL and Ponded Width (Spread)

Linearly Interpolate between points on NOAA Atlas 14 IDF Curve

Develop IDF Equations Current RTI Project to develop IDF equations

Cell Library not developed for other utilities conduit/boxes etc.

Planned development after hydraulic/storm-sewer component.

Planned completion in December 2019
