CHAPTER 1 SUPERELEVATION

Objectives

1.1 Objectives

• Learn how GEOPAK defines a roadway crown.• Learn the variables used to calculate superelevation in the txdot_v8i.sep.• Learn to use GEOPAK Automated Superelevation and Graphics Shape Maker to apply

superelevation to a roadway.

1.2 Definition

The process of placing a complex shape, which represents an area of constant slope or an area of superelevation transition in a design file. GEOPAK uses three tools to calculate superelevation transition locations for any chain stored in the coordinate geometry database. The result is an ASCII file that lists the stations and slopes for each superelevation transition break. Transition breaks are depicted by shapes. A shape is a complex element drawn in MicroStation (2D) to represent the roadway crown. Reference GEOPAK Help Files, for more information. You will need to be familiar with the following files and tools:

• txdot_v8i.sep - stores the variable settings used in calculating superelevation transition lengths.

• txdot_e_v8i.csv - contains the radius table values from the TxDOT Design Manual used in calculating superelevation transition lengths.

• txdot_length_v8i.csv - contains the Minimum Length and Relative Gradient values from the TxDot Design Manual used in calculating superelevation transition lengths.

• Automated Superelevation - is used to create an input file for applying super elevation transition locations along a specified alignment.

• Graphics Shape Maker - permits interactive creation of superelevation shapes defined by graphic elements drawn in a MicroStation file.

• Superelevation Shape Manager - permits access to all GEOPAK Superelevation tools.

Accessing Automated Superelevation

1.3.1 File

From within the Automated Superelevation dialog box, several options are supported under the Filemenu as shown below.

• Directories - Enables the user to view and change the four directories used by GEOPAK for superelevations. These directory paths have been set for you by a config-uration variable. The directory paths should display to:

C:\Engapps\TXDOTGPK\superelevation

• Preferences - - By attaching the txdot_v8i.sep file, GEOPAK will automatically attach the txdot_e_v8i.csv and, txdot_length_v8i.csv setting files and define addi-tional settings used in calculating superelevations in accordance with the TxDOT Design Manual

• Level Symbology - Allows the user to define the symbology to be utilized when shapes are plotted. When double-clicking within the symbology area, GEOPAK will activate the set feature dialog box.

Automated Superelevation

1.4 Automated Superelevation

The Automated Superelevation dialog box is accessed from Project Manager >> Calculate Super-elevation.

• Preference Files - Ascii file that holds the users superelevation preferences• Transition ID - accesses the XS.TD file to apply type of superelevation (linear or parabolic)• Facility - sets the type roadway project (undivided or divided)• L Selection - sets the minimum superelevation transition length• Input File - Name of an input file (.inp) that is created when Generate Superelevation

Transitions is selected• Chain - the GEOPAK baseline chain (representing the horizontal geometry) to which

superelevation transitions are applied• Profile - the name of the design profile• Tie - distance that determines the location of the Profile Grade Line (PGL) expressed as an

offset to the baseline or allows you to pick another chain as the PGL• Design Speed - the design speed that determines the rate of superelevation for curves


10/9/12


Automated Superelevation

The Offset box within the dialog box is a collection field for storing the % Slope, offsets, and the dependency of the superelevation shapes to be generated.

• % Slope - normal cross slope of the roadbed entered as a percent (e.g., -2 = -0.02)• Offset - defines the dimension of the shape by two offset distances from the baseline.

Negative values indicate offsets to the left• Dependency - refers to how elevations on the pavement surfaces, represented by the shapes,

are calculated. Each shape cluster (set of shapes) must have one dependent shape. A dependent shape’s elevations are determined directly from the pro-file. An independent shape’s elevations are derived from an adjoining shape.

Once all data is entered, select the ADD button and the information is displayed in the collection field. This procedure is repeated for each segment of the pavement, both left and right of centerline. After all segments of the pavement have been defined and placed in the collection field, the designer clicks the Generate Superelevation Transitions button and the Superelevation process is executed.

An input file with a .inp extension is created and placed in the project directory. This input file shows where superelevations will be applied by indicating station and slope along a roadway. This is an ASCII file that may be reviewed and/or edited.

A sample input file is provided on pages 1-8 & 1-9.

1.4.1 Parabolic Transitions

TxDOT uses a parabolic transition as a recommended method for superelevation transitions. GEOPAK provides a method for applying parabolic transitions. An ascii file (xs.td) found in the C:\Program Files (x86)\Bentley\GEOPAK\v8.11\bin directory allows the designer to create linear, parabolic, or parabolic-tangent-parabolic transitions.

TxDOT applies parabolic transitions over the entire transition length of the outside shape. This means the longer transition length station is entered for the inside shape.

XS.TD

Transition No. Sag Parab Length Tangent Length Crest Parab Length 0 0 1 0

1 1 0 12 45 1 55

Transition def = 0 linear transition applied over the entire transition length (default)

Transition def = 1 back to back parabolic transition over the entire transition length(RECOMMENDED METHOD)

Transition def = 2 parabolic-tangent-parabolic transition applied over transition length;the designer enters the length of the desired parabola

Note: The statement Apply Trans def = # is entered in the design cross section input file (covered in the following chapter).

1.5 Create Superelevation Shapes

Once the shape input file (filename.inp) has been created and reviewed, the designer can process the input file to place the superelevation shapes in the specified graphics file by clicking on the Create Superelevation Shape button.

Shape Maker

1.6 Shape Maker

Not all superelevation transitions can be defined by station and offset. GEOPAK provides the Graph-ical Shape Maker for situations that involve left turn lanes, merging roadways and, in some cases, widenings.

The designer will use simple MicroStation elements to depict the area to which superelevation is applied. Once the area is drawn, the Graphical Shape Maker dialog box allows the designer to define the roadway information to apply superelevation. The MicroStation elements are then identified and a complex shape representing the superelevation is created.

Access Shape Maker from the GEOPAK Project Manager by selecting Superelevation Shapes

Parameters• Baseline - chain corresponding to the shape• Profile - profile controlling shape• Class - Dependent or Independent, as previously discussed• PGL Chain - chain name for shape if profile is defined by a chain other than the baseline• TransID - determines linear or parabolic transition• Tie - distance that determines the PGL; expressed as an offset to the baseline• Identify Shape - displays the parameters of a previously defined shape• Symbology - defines the symbology to be utilized when shapes are plotted• Slope Label - defines the symbology to be utilized when slope text is plotted.

Cross Section Shapes

1.8 Cross Section Shapes

After learning how to create superelevation shapes, the next procedure is to place these shapes on cross sections. The following is a design cross section input file (.inp) that will place the shapes in an existing MicroStation file containing original ground cross sections. (Note: This information may be executed through the Project Manager.)

Proposed Cross Sections

1.9 Proposed Cross Sections

When the Proposed Cross Sections button in the Road Project Manager is pressed, the Select Run dialog is displayed. An existing run may be selected or new run may be started. When com-plete, press the OK button which closes the Select Run dialog and the proposed cross sections dialog will appear as depicted to the right.

The left side of the dialog contains the list of parameters required to process proposed cross sections. When each parameter is selected, the dialog changes to reflect the requirement of each parameter. For example, when Plot Parameters is selected, the dialog changes to reflect the various plot parameters and text as depicted to the right.

When Pattern is selected, the dialog changes to the illustration to the right. Three dialogs (Pat-tern, Existing Ground, and Shapes) support a toggle to Use Working Alignment Definition. For example, in the Pattern dialog to the right, the toggle is not active, therefore the user must supply all pattern information. However, if the toggle is active when one of these three dialogs is invoked, the data information part of the dialog is ghosted and the required information is utilized from the current working alignment. If the toggle is activated, and the required infor-mation is not stored within the current working alignment, an Alert message is displayed.

The majority of dialogs follow the standard input for proposed cross sections, however, three dialogs have enhancements not found in the input file. These dialogs are: Shape Clusters, Define DGN


10/9/12



Variables, and Define Variables.

When the Shapes parameter is selected, the dialog is displayed as depicted to the right.

Three Shape options are supported:All in DGN - All shapes within the specified

file are utilized.

By Search Criteria - Only those shapes which match the specified search parameters are uti-lized.

Shapeless - No shapes are utilized. In this option, there is no field for a shapes file name or files button.

When the Shape Clusters parameter is selected, the dialog dynamically changes as depicted to the right.

The user may Add, Delete, or Modify any specified shape clusters. When the Scan button is pressed, GEOPAK scans the design file and search criteria specified in the Shapes dialog and lists all matching clusters. In the case of shapeless criteria, the user must define one cluster by typing in the Chain, Tie and Prof, then pressing the Add button.

Under Files, the options are Run, Save Settings, Export... and Exit. To process, press the Run button, which invokes the Process Cross Section dialog. Save Settings simply saves the current

settings to a resource file. When the File >> Export option is selected, the user may save the dialog information in an ASCII input file for subsequent processing. The dialog below appears wherein the user specifies the Name.

The File >> Exit option enables the user to exit the Proposed Cross Sections dialog box. The software also prompts the user if the settings should be saved before exiting with the Alert box. Pressing the Yes button will save the current dialog settings, No will not save the settings, but both buttons will exit to the Project Manager.

EXERCISE 1.4 - PLOTTING SHAPES ON CROSS SECTIONS

In this exercise you will generate original ground cross sections and create an input run to draw superelevation shapes into the cross section file.


Step 1 Create patt.dgn (2D) and create a new run called Patt using Project Manager to draw pattern lines for chain, base1, at 100 foot increments, offset 150 feet left and right from station 0+00.00 to station 60+00.

Use these parameters: lvname = D_PATTERN_LINE_1co = 4lc = 4wt = 4

Step 2 Create xs.dgn (2D) and draw original ground cross sections using pattern by dgnfor chain base1. Tin file name: topo.tin.

Use these plot parameters: Scale hor = 10 vert = 5 Voids lvname = XS_VOID_1

co = 0 lc = 3 wt = 3

General lvname = XS_ORIGINAL_1 co = 2 lc = 3 wt = 1





Step 3 Create dxs1.dgn by saving xs.dgn as dxs1.dgn.

Step 4 Using Project Manager, select Proposed Cross Sections and create Run ex14. Use information from the following dialog boxes.

Step 5 Enter xs.dgn and process cross sections. (You will notice that GEOPAK will take you to dxs1.dgn)

Step 6 Go to Cross Section Navigator and view shapes.


2 CRITERIA/DESIGN CROSS SECTIONS

2.1 Objectives

• Understand what criteria is and how GEOPAK utilizes it to define design cross sections• Become familiar with TxDOT's criteria library• Use Project Manager to create proposed cross section runs and input files• Be able to use criteria to define new location, widening, and urban design cross sections

2.2 Definition

Criteria files are free format ASCII text files that evaluate conditions GEOPAK uses to make design decisions. For example, criteria will check maximum slope intercept for a ditch section then select the proper slope to tie to existing ground. Criteria files will consider each cross section individually, making this a very helpful and flexible tool.

Criteria is also used to place structures on the design cross sections, such as, curb and gutters, concrete traffic barriers and retaining walls.

Using criteria files, the designer is able to input values for design options (DEFINE Variables) and use MicroStation elements to identify specific design features (DEFINE_DGN Variables). Fol-lowing are descriptions and examples of elements that may be included in a criteria file.

DEFINE Variables text string keyed-in by the user to define a design optione.g., define “cutslope 1” 6:1This defines the first cut slope using a run:rise value of 6:1

DEFINE_DGN Variables a series of text strings used to describe a design option or featurestored in a MicroStation graphics file as a MicroStation element

e.g., define_dgn “ROW” \dgn = plan.dgn \lvname = D_ROWLINE \co = 6 \lc = 0

This is pointing to the dgn variable “ROW” and indicates where the feature is in the specified design file by level, color and line code.

Intrinsic Variables are roadway characteristics set by GEOPAK. For example, pavement slope ispre-defined by the software and can be checked at any cross section.

Marked Points are locations within a criteria file marked so that they can be recalled to tieto, to evaluate conditions, or to draw from. An example of this is marked point110. This point is the ROW Berm Dist inside the ROW line that slopes musttie to (max slope intercept). All marked points are labeled on

level XS_MRKPNT of a design cross section and are used by TSD to debug any problems with a particular criteria file.

NOTE: A backslash is required on every line of text except the last when defining a DGN variable.


CHAPTER 2 Criteria/Design Cross Sections

Operation

Hinge Point location (marked point) at the edge of a cross section shape cluster identified by a criteria file and used as a reference point for additional criteria. This is the

only marked point whose location may change.

The GEOPAK Support Team at TSD has created a TxDOT Criteria Library to be used on department projects. Please contact this team with any question on using criteria or for any requests for additional criteria files. The GEOPAK Support Team will not support criteria files created by individual users, but will add any needed criteria files to the TxDOT Criteria Library.

The designer is not expected to create criteria, but must know how to apply it to a design cross section.

2.3 Operation

Criteria files are referenced from a project run or an input file. When the data is processed, design features are drawn in a cross section design file. The designer indicates what shape cluster to apply criteria to and identifies any variables that may accompany the criteria file.

Example: define_dgn "ROW" \ Define_DGN VariableInput file dgn = plan.dgn \

lvname = D_ROWLINE \co = 6 \lc = 0

define "ROW Berm Dist" 5 Define Variable

side slope ltinclude c:\engapps\txdotgpk\criteria\row01.xinclude c:\engapps\txdotgpk\criteria\srf02.x

The TxDOT Criteria Library was created to aid in the development of design cross sections. A naming convention has been established to help determine what group of criteria files should be selected. For example, ROW01.X is the criteria file that places the R.O.W. line on cross sections. The file named BSE01.X is used to draw the base on a curb and gutter section. Each criteria file has an accompanying document which explains the use of the criteria file. This document file (Criteria_V8i.pdf) tells the designer what variables will be used and when to include the criteria in the run or input file. Pages 2-3 and 2-4 depict the document to accompany ROW01.X and the criteria file itself.


10/9/12


Operation

Example Document File

ROW01

Description:

This criteria file draws the ROW line on a design cross section and establishes a maximum location for cut and fill slopes to tie to existing ground. Level = XS_LBL_1.

The designer is required to enter a distance inside of the ROW line (ROW Berm Dist) to mark the maximum slope intercept allowed. ROW01.X reads the ROW line drawn in the plan view of a .dgn file then considers the value of the ROW Berm Dist before determining how to tie to existing ground.

DEFINE_DGN Variables:

ROW plan view graphic element representing the limits of Right of Way. Must be drawn using place influence. If right of way has not yet been determined, the user should still place a line in order to establish a location to tie slopes to existing ground. The message NO ROW FOUND will be placed if no graphic element is drawn.

DEFINE Variables:

ROW Berm Dist the distance inside the ROW line where the slopes (cut or fill) must tie to exist-ing ground. May be zero if the designer wishes to tie at the ROW line.

Insertion Location:

This should be the first criteria file in the series after HNG01.

CHAPTER 2 Criteria/Design Cross SectionsCriteria Procedure

10/9/12

2.4 Criteria Procedure

Certain procedures must be followed to use the TxDOT Criteria Library. Specifically, the order in which the criteria files are processed (within the design cross section input/run file) is critical for successful runs. For example:

• the designer must place the right of way line and the “ROW Berm Dist” in a design cross section before the software can establish the max slope intercept.

• if ROW01.X is not the first criteria file in a design input file, other criteria files may not work properly.

When a general ditch criteria file is used (GEN01.X), the criteria file checks the “ROW Berm Dist”to determine which slope option to use to tie to existing ground. Specific locations are marked with one criteria file and then recalled with another. Therefore, it is important to pay attention to the stacking order of criteria files in a design input/run file. To aid the user, each document that accompanies a criteria file gives an Insertion Location for the file.

Once a “ROW Berm Dist” has been defined in a cross section, the designer will use a criteria file to establish a hinge point (or location) at the edge of the shape clusters. To process the design input/run file, the following steps are recommended:

Step 1 include a single criteria file in the design input/run file

Step 2 process a few cross sections and verify the results

Step 3 abort the run and delete the proposed cross section elements

Step 4 add another criteria file to the design input/run file

Step 5 repeat steps two through four

Repeat this process until all criteria files have been included. These steps allow the user to build the design cross section gradually and will reduce errors caused by processing a large number of criteria files at one time. A greater number of criteria files may be included in a design input file after the designer becomes experienced in the use of criteria. Design input runs/files may be saved to use on other projects.


EXERCISE 2.2 - New Location Ditch Section with Criteria

Expand the design cross section from Exercise 2.1, by using criteria files to place a ditch section on the cross section to show the ROW location (ROW01.X), hinge point (HNG01.X) pavement(SRF04.X), ditch slopes (GEN01.X) base (BSE08.X) and earthwork line (EWLINE04.X). Refer-ence Drawing 2.1 on page 2-12.


Step 1 Make a copy of the original ground cross section file (xs.dgn) and name it xsd.dgn.Only original ground cross sections and the GEOPAK cross sectioncells should be in this file. This file will be used to place design crosssections while still maintaining an original ground cross section file.

Step 2 From Project Manager >> Proposed Cross Sections, copy ex14 and name it ex22. (Descr. - New Location Ditch)




Step 3 Edit ex22 from Project Manager. Add the criteria files HNG01.X and SRF04.X and update all necessary information. Refer to Appendix A, pages A-4 to A-5, for Define Variable Values.

a.) Change the xs dgn file to xsd.dgn

b.) Update the Define DGN Variables and Define Variables.

NOTE: HNG01.X will place a hinge point to which the other criteria will tie.

c.) Change the plot parameters.

EXERCISE 2.4 - LANE WIDENING (SHAPELESS CRITERIA)In this exercise criteria will be used to place an overlay on an existing roadbed and widen the road to include an additional lane with a shoulder. You will use plan view graphics to identify the existing edge of pavement, the proposed widening and the ROW line. You will also apply the “LTRT” side slope condition. A criteria file (SRF03.X) will locate the centerline and the existing edge of pavement at each cross section taken and calculate the slope. See Drawing 2.3 on page 2-18. Since we are matching the existing cross slope of the roadway, no shapes are required (shapeless).


Step 1 Create wide.dgn (2D) and enter. Load and Read input file exist98.itc.

Step 2 Draw and annotate chain EXIST.

Step 3 Draw a ROW line, 50 ft. left and right of chain EXIST.

Step 4 Draw a proposed mainlane edge of travelway, 28 ft. left and right of chain EXIST (this will be the proposed widening).

Step 5 Draw existing edge of pavement, 12 ft. left and right of chain EXIST using the following MicroStation settings: lvname = D_MISC_1, co = 3, wt = 1 & lc = 0.(this edge is the start of the widing).

Step 6 Create an original ground profile, GRND, using topo.tin. In Select Run dialog box create new Run ex24 with Description Original ground along chain EXIST.

Increment every 100 ft. along chain EXIST.




Step 7 Create pattw.dgn and draw pattern lines in it using the information below:

EXERCISE 2.5 - RAMP CONNECTIONIn this exercise you will create design cross sections on a two lane roadway with an exit ramp. You will apply superelevation shapes for the ramp transition section and the ramp typical. Criteria files will be applied to two separate shape clusters (transition section and ramp).

Step 1 Enter Rshape.dgn and attach as a reference file Ramp.dgn.a. Set the active level to D_GEOM_SCR_1 and turn off level

D_SHAPE_DEP and D_SHAPE_INDEP;b. Turn off levels D_ALIGN_4 and D_ALIGN_ANNO_4 in the Ramp.dgn

reference file.c. Zoom in to Sta. 50+00 using chain “Base1” (Hint: Use DP/Station Offset)

Step 2 In COGO; set the visualization preference to “Disable Visualization” then load and read the input file ramp98.itc. This input file contains the alignment “RAMP”and profile “RAMP” for the ramp, also the ditch profile “RDITCH” for the gore ditch is included.

Step 3 Draw a line radial (perpendicular) to the chain “RAMP” from -15 feet to 20 feet to the right at stations 49+30.00, 53+96.73 and 55+27.18. These lines will be used as filler lines to identify the cross slope for the superelevation shapes. (Hint: Use DP/Station Offset)





Step 4 Using Shape Maker create the two shapes that will be represent the gore transition area and the ramp section. Use the Automatic mode to create these shapes.Transition ShapeSta. 49+30.00 filler line slope = -2 Independent

Ramp ShapeSta. 55+27.00 filler line slope = -2 Dependent

Turn on levels D_SHAPE_DEP and D_SHAPE_INDEP to view all shapes.




Step 5 Enter Rampxsd.dgn and select Proposed Cross Sections from Project Manager. Copy Run ex22 and name it ex25. This run will save the design elements in a new cross section file. Process only the pattern lines (yellow) along the main lanes and ramp transition up to the gore. Make the following modifications to the new run; save settings and process it.

XS DGN file - Rampxsd.dgn Pattern file - Pattr.dgn Existing ground file - Rampxs.dgn Shape file - Rshape.dgn

Step 6 Copy run ex25 and name it ex25a. In this run, edit the pattern search to read only the pattern lines (magenta) along the main lanes and main ramp section, notice these pattern lines are drawn as line strings in the pattern file. Also remember to add the Shape Cluster for the ramp section using the scan button and adding it to the shape cluster collection field. Apply criteria as indicated below. For DGN_variable M_DITCH use yellow line in Ramp.dgn

Design Cross Section Modification Accessing

2.5 Design Cross Section Modification

Criteria files are flexible tools that allow multiple design conditions to be considered. However, there will be occasions when a criteria file cannot address a particular condition on a cross section. There is no need to edit a criteria file or design input file if the desired cross section can be created using MicroStation commands and/or the GEOPAK Cross Section Labeling Tool. Since GEOPAK uses MicroStation elements to calculate earthwork volumes, the designer can simply modify the cross section in MicroStation. The result will be the final design cross section used for volume calculations.

2.5.1 Accessing

GEOPAK provides a tool, the Cross Section Labeling Window, to assist in the review and modifi-cation of cross sections. This dialog box can only be accessed while in a design file containing cross sections.

From the GEOPAK Road >> Cross Sections >> Labeling.

The cross section labeler dialog box contains three menu options and six different tab options. Of the tab options, the Text tab is the most utilized option. It allows for the placement of Computed Text Inserts and User inserts.

Computed text inserts are calculated values such as slope, offset, and xy coordinates, which are related to a cross section element or a data point.

User inserts consist of commonly used text strings, labels and notes. Since user inserts are defined in an ASCII text file, the user has the option of modifying or adding to the user inserts file


10/9/12



.

Parameters allows the user to define text size, style, level, color, weight and justification. These settings can be defined By Current, or By Element.Set All instructs GEOPAK to read the current settings (level, weight, color and style)within the dialog, and populate the Shape and Leader dialogs


10/9/12



.

Shape allows the user to define a shape to be placed around any text output used in labeling.

Leader allows the user to select a Leader Type and a Terminator as well as the symbology for each.


10/9/12



Rotate gives the user options for selecting and setting angles for output placement.


10/9/12



Styles provides the user with the tools to select, define and save styles for label placement. This is useful for recalling settings for labeling.


10/9/12


EXERCISE 2.6 - CROSS SECTION MODIFICATION

You will use a combination of GEOPAK and MicroStation commands to modify a design cross section created in Exercise 2.2.

Step 1 Enter the design cross section file, xsd.dgn

Step 2 Open the GEOPAK Cross Section Labeling Window(The software will scan the design file, attach the alignment, display the first station and window area the first cross section).

Step 3 Go to station 49+00.Window Area to fill the view with the cross section.

Step 4 Edit the cross section:Change the fill slope on the left side of the cross section to tie to the existing ditch bottom. Turn on level xs_mrkpnt and move pt 50 to the new

ditch location.

Step 5 Measure and label the new slope.Place the slope text at the angle of the modified line.(Match the display parameters of existing slope text.)

Step 6 Edit the cross section:On the right side of the cross section, change the cut slope to tie to existing ground at the ROW Berm Dist (maximum slope intercept). (Point 110)

Step 7 Measure and label the new slope.Place the slope text at the angle of the modified line.(Match the display parameters of existing slope text)


3 EARTHWORK

3.1 Objectives

• Learn the procedures for calculating earthwork quantities with GEOPAK• Learn how to use Project Manager to set up and process an earthwork run.

3.2 Definition

GEOPAK forms earthwork shapes in a design cross section .dgn file to represent the end areas used to calculate volumes. These shapes are created when the designer processes an earthwork run in which the existing ground, finished grade, base, etc. are identified by level, color, weight and type.

3.3 Accessing

To access the necessary dialogs needed to create and process an earthwork run, select the Earthwork button from Project Manager as depicted below.


CHAPTER 3 Earthwork
Accessing
After choosing the Earthwork button, the Select Run dialog box appears. An existing run may be selected or a new run may be created. Once the run is selected the Earthwork dialog will appear as depicted below.

The left side of the dialog contains the list of parameters required to compute earthwork. When each parameter is selected, the dialog changes the keyin fields to reflect the selection. The user must select each parameter and enter the appropriate data. The following dialog box has been completed as an example.


CHAPTER 3 Earthwork
Soil Types
3.4 Soil Types

3.4.1 Functional Classes

Functional classes identify the function or purpose of the cross section element and are determined by the designer. All classes except Excavation Limit require a Soil Type and Search Criteria. The choices are as follows:• Proposed Finished Grade - Required• Existing Ground - Required• Proposed Undercut - Optional• Existing Suitable - Optional• Existing Unsuitable - Optional• Excavation Limit - Optional In order to compute the most basic earthwork, only Proposed Finished Grade and Existing Ground are required.

3.4.2 Multiplication Factors & Mass Ordinate

Multiplication factors can be specified for each material type and different factors can be used for excavation and fill. Use the toggle Do Not Include In Mass Ordinate provided on the Earthwork dialog box to exclude a specific material from the mass ordinate.


CHAPTER 3 Earthwork
EW Shapes
3.4.3 Search Criteria

Assigning the element symbology for each class and soil type is very important. Therefore the user should make use of the Match tool provided on the Earthwork dialog box.

3.5 EW Shapes

This section determines how the earthwork shapes will be drawn into the dgn file. We recommenddrawing the shapes into the dgn file for review purposes. And toggle on the Stratify Shape Color to differentiate the soil types.


CHAPTER 3 Earthwork
Output Format
3.6 Output Format

Three classifications of excavation volumes are listed on standard GEOPAK earthwork outputs: common, subgrade and subsoil. The designer can customize the Output Format as desired through the use of the check boxes, arrow buttons and decimal place toggle.

3.6.1 Excavation Types

GEOPAK supports the following types of excavation which are determined by the software and not the designer:

• Common Excavation - Volumes that are not backfilled with earthwork material.• Subgrade Excavation - Volumes that are backfilled with an earthwork material.• Subsoil Excavation - Volumes are required to remove unsuitable material

3.6.2 Embankment Types

GEOPAK does not have various types of fill like it does excavation. Fill volumes are determined from the graphic elements in the cross section file.

4 REPORTS

4.1 Objectives

• User should be able to create various cross section reports:- for plan use (design elements and quantities)- as input for other programs and/or applications of GEOPAK- for construction layouts- for deliverables to contractors

4.2 Definition

The GEOPAK Cross Section Report Utility can create up to sixteen different reports from original and design cross-sections. For each report generated, the user must use the parameters (alignment, station range, symbology) of the existing and/or design cross sections. GEOPAK also provides an option to make custom headers for each of the reports via the User>>Preferences pull down menu.

4.3 Accessing

To access the XS Report select GEOPAK ROAD>>Project Manager>> Reports & XS Quantities.

4.4 Custom Header

From the XS Report dialog box select User >> Preferences; a Report Headerdialog box will appear with all options ghosted out. To activate the individual fields simply toggle on the box next to the desired field. Once you have completed the dialog box, the information will be saved as a .hdr file. In this way you can make a separate header for each type of report. The tolerance field determines the maximum gap allowed between cross section elements.


CHAPTER 4 Reports
Reports
4.5 Reports

Blue and Red Top

Based on the dialog box settings, GEOPAK determines the offset and elevation of a slope and its breakpoints. Blue refers to the top of pavement and Red is the top of subgrade. The user must determine this by indicating the level, color, weight and style for each surface.

Clearing

The Clearing Report is useful for obtaining clearing and grubbing quantities. For each sta-tion, GEOPAK will list the clearing distance on each side of the chain and the width of any exception. You can obtain the results in feet squared and/or acres. Toggle boxes for Cut Slope Rounding, Additional Clearing in Cut and Fill, and Minimum Clearing Width are provided for increased control over the output.

GEOPAK can also generate quantity sub-totals based on the value specified in Sub Every.

To use the Except Width option, you must have an existing ASCII file that includes the Beginning and Ending Station and Exception Width.

Once everything is set, you can output the information to an ASCII file.

Closure

The Closure Report provides information on the intersection point between the user defined proposed finish grade and existing ground. In addition to the ASCII report, the designer may instruct GEOPAK to close any gap either by drawing a vertical line between the endpoint of the proposed finish element and existing ground or extending the slope of the last proposed element to intersect existing ground. The procedure will not extend existing ground. The Closure Report can be accessed within any MicroStation cross section file by selecting Closure from the main XS Reports dialog. The dialog depicted below is displayed.


CHAPTER 4 Reports
Reports
DTM Input

This process generates XYZ coordinates from cross section elements and creates an ASCII file (.dat). With the .dat file the user can create a DTM (.tin). To use this dialog box simply enter the .gpk job number, chain name and station range. GEOPAK will read the cross section elements based on level, weight, color and style.

DTM Proposed 3D

This report is similar to DTM Input except that you can set both original and proposed cross sections at the same time. This report also differs in that it makes breaklines across the cross sections. This report is useful when making 3-D cross sections for modeling purposes. It is also used to produce proposed contours.

HEC-2 & HEC RAS

This process reads cross section elements and formats the information in an ASCII text file suitable for use in the HEC-2 & HEC RAS hydraulic programs.

Multi-Line

This report is useful in creating cross-sections for staged construction. Begin by entering the job number, chain name and station limits. Primary cross section element parameters must be completed before secondary element parameters. This is important due to the order in which GEOPAK reads the information. Once all the parameters have been entered, the new cross sections may be drawn to the design file or you may choose the display only option. An ASCII text file will be generated.


CHAPTER 4 Reports
Reports Profile Grade
Profile Grade

The Profile Grade Report is one of the most versatile reports available. It prints existing ground and design grade elevations and low point elevations for each cross section. Addi-tionally, this report has the ability to create horizontal and vertical alignments along the low points and store them directly into the .gpk. Horizontal alignments created from this report will start with station 0+00 and have no curves.

To use this report, fill in the parameters appli-cable to your project and choose the appro-priate options.

Radial Staking

The Radial Staking Report is a specialized report created for the U.S. Federal Highway Adminis-tration (FHWA).

RT 40

The RT 40 Report produces RDS based RT40 data. To use this dialog box simply fill in the job chain name, stationing range and the parameters of the cross section elements you wish to use.

CHAPTER 4 Reports
Reports Seeding
Seeding

Other than the usual entries, the user must enter the parameters of the elements to be seeded.

This dialog box includes slope and subtotal options as well as a way to limit the number of segments read (ByPass Segments). The user may also establish additional seeding specifications (Additional Distance).

Once all of the settings are complete, the report is written to an ASCII output file for use in PS&E Quantities.

Slope Stake

The Slope Stake Report is a special format report developed for the FHWA. This report generates offsets, elevations and superelevation information for each cross section. To generate this report fill in the usual cross section parameters plus Subgrade and Hub Staking information. When complete, push Apply and the report is written into an ASCII file.

Staking Detail

The Staking Detail Report determines the tie down point between the proposed finished grade and the existing ground. GEOPAK will list the right and left offset, elevation, slope of the finish grade and superelevation rate for each cross section. To create this report, fill in the project information and desired cross section elements’ parameters. Once complete, you have the choice between two formats, a FHWA ASCII report or a Montana DOT report (includes ditch elevations).

WSPRO

This report takes the cross section elements and turns them into an ASCII file in the WSPRO format for use as input in the WSPRO hydraulic analysis program.

XS List

This report creates a listing of elevations and offsets for each cross section element according to user defined parameters. You have the option of creating either an original cross section list or a design cross section list. (Recommended for Contractor Information)

5 UTILITIES

5.1 Objectives

• Designer will be able to place and label utilities on design cross sections and profile.• The new dialog box replaces the Ancillary Data Input file in prior GEOPAK versions.

5.2 Draw Ancillary Features

The Draw Ancillary Features tool can be accessed from either the tool palette or the Applications pull-down: GEOPAK ROAD >> Cross Sections >> Draw Ancillary Features.

This tool can be accessed from both GEOPAK ROAD and GEOPAK SITE.

The Ancillary Feature tool can only be used for drawing on cross sections or profiles with a GEOPAK “Green Cell” drawn.

5.3 Overview of Ancillary Dialog Box

This feature box has standard file utilities such as, Load, Save, Save As and Exit.

All files saved have a *.AFD file extension. This file saves the dialog settings and can be reloaded for editing.

Edit options are to save settings, clear lists, etc.

Update Options are user-defined options on how the software handles the redrawing of data.


CHAPTER 5 Utilities
Draw
5.4 Draw

The Job Number is required to identify the Coordi-nate Geometry database where the chain is stored.

The Chain feature allows the user to select an align-ment for the Draw Ancillary Feature to follow.

Label Scale is utilized when the By Feature Display setting is used. The specified Label Scale is compared to the scale within the D&C Manager Item. This option is only used if the text settings are set to scale and not fixed.

Station Range settings allow the designer to specify a Beginning and Ending Station for the Draw Ancillary Feature to read when the Draw button is clicked.

5.5 List Box

Each Ancillary Feature and Test to be drawn must be added to the List Box. Once added. each feature can then be modified or deleted if needed. The Add Element Set, Modify Element Set and DeleteElement Set are located to the right of the List Box.

Ancillary Element Sets in the box can also be turned off and on using the Draw toggle.

CHAPTER 5 Utilities
Intersecting Elements
5.6 Intersecting Elements

The Intersecting Elements dialog allows the user to specify the offset (plan view location) and elevation of the utility.

Within the Intersection Elements portion there are four options in which to choose from.

• Chain - allows the user to specify any chain in the active gpk file. The selected chain will then be used to calculate the offset of the Ancillary Feature

• Survey Chain - allows the user to specify any survey chain. The selected chain will then be used to calculate the offset of the Ancillary Feature

• Level Symbology - allows the user to assign specific graphic symbology for any element. This option requires the name and location of the DGN file that the ele-ment is drawn in.

• Feature - this tool works the same as the Level Symbology tool, except the Feature tool uses the D & C Manager to specify symbology.


10/9/12

CHAPTER 5 Utilities
Intersecting Elements Vertical / Elevation Options (Chain)
5.6.1 Vertical / Elevation Options (Chain)

The user also has four options in which to specify the vertical / elevation settings of the ancillary feature under the Chain option.

When selecting the Chain option for Intersecting Elements, the default option finding the elevation is a COGO Profile. Both the chain and the profile must be stored within the user gpk file.

• COGO Profile

When the user toggles on the Extract Elevation option, three other options become available:

• TIN - this option works in conjunction with the Vertical Offset. First, the elevation of the DTM at the chain is calculated, then the Vertical Offset (depth of cover) will be applied to determine the elevation of the ancillary feature.

• Level Symbology - this option also works in conjunction with the Vertical Offset. But, in this case the offset is calculated from a graphic element in the DGN file (specified by the user).

• Feature - this option also works in conjunction with the Vertical Offset and is very similar to the Level Symbology option, except instead of taking the symbology from a user de-fined element, it takes symbology from a D & C Manager defined element.

CHAPTER 5 Utilities
Intersecting Elements Vertical / Elevation Options (Survey Chain)
5.6.2 Vertical / Elevation Options (Survey Chain)

When selecting the Survey Chain option for Intersecting Elements, the default option for finding the elevation is the Survey Chain itself because all Survey Chains have elevations stored within them.

5.6.3 Vertical / Elevation Options (Level Symbology & Features)

When selecting the Level Symbology option for Intersecting Elements, the user can toggle the Extract Elevation on and select the TIN option. The offset is calculated from a graphical element in a specified DGN file.

The elevation of the DTM at the chain location will be calculated, then the vertical offset (depth of cover) will be applied to determine the elevation of the ancillary feature.

The Feature toggle is very similar to the Level Symbology, except that the symbology is taken from a D & C feature instead of a user defined element. The elevation of the DTM at the chain location will be calculated, then the vertical offset (depth of cover) will be applied to determine the elevation of the ancillary feature.

6 3D MODELING

6.1 Objectives

• create 3D Cross Sections from 2D Cross Sections• interpolate between 3D cross sections to create B-Spline surfaces• use Drive Through to view the model

6.2 Definition

GEOPAK 3D Modeling is a process of deriving three-dimensional cross sections from 2D Cross Sections and interpolating between the 3D Cross Sections to create B-Spline surfaces that represent the design.

6.3 Prerequisites

Before a 3D model can be extracted from 2D Cross Sections, there are a few prerequisites that must be met. They are:

• 2D design Cross Sections• plan view graphics• 3D design file

2D Design Cross Sections

The Designer must have a design file where 2D Cross Sections are stored. The levels containing the existing ground line and the proposed finished grade must be known for processing.

Plan View Graphics

The plan view graphics should include the elements specified in the proposed cross section for Define_DGN variables. Also any other additional elements that correlate to the vertices of the design cross section elements. For example, edge of pavement, pavement markings, sidewalks, ctbs, retaining walls, etc. A baseline chain must also be drawn into the file.

3D Design File

A blank 3D design file must exist to store the 3D Cross Sections and for the 3D Alignment to be drawn. The 2D plan view graphics file will be attached as a reference file. Save the settings of this file with the Top View displayed.


CHAPTER 6 3D Modeling 3D Modeling Tools

6.4 3D Modeling Tools

From a 3D design file, access the 3D modeling tools by selecting GEOPAK Road >> Project Manager >> 3D Models. The dialog box will appear requiring a job number and chain name. Descriptions of available 3D modeling tools follow:

User > Preferences The Tolerance defines the distance such that two elements with endpoints closer together than the tolerance values are assumed to be connected, if greater than they are assumed to be coincident. The Min Rule Spacing dictates the number of elements comprising each B-Spline surface. The smaller the Min Rule Spacing, the more elements in each B-Spline.

• 3D Alignment - will draw elements into a 3D file, at correct coordinates, using the specified chain and profile.

• 3D Cross Sections - will reference your 2D cross section file and create a 3D complex chain to represent the 3D Cross Sections.

• Interpolate Between Sections - interpolates between the 3D Cross Sections to create B-Spline surfaces.

• 3D Pavement Markings - will add pavement markings to a 3D model. The pavement mark-ing tool will scan pavement markings in a 2D file and draw the markings in the 3D file based on user defined parameters.

6.4.1 3D Alignments

3D Alignments draws space strings into the 3D file at the correct coordinates utilizing a specified chain and profile. The Offset is measured horizontally, with a negative offset to the left of the chain. A scale ratio must also be specified. This ratio will be 1:1 for modeling purposes. For the 3D Alignment to be utilized in the model, the 3D strings must coincide with vertices of the Cross Sections.


CHAPTER 6 3D Modeling 3D Cross Sections

6.4.2 3D Cross Sections

Generate 3D Cross Sections:

• Enter the 2D cross section file containing design Cross Sections; GEOPAK reads the file to determine the beginning and ending station of the Cross Sections. These sta-tions are automatically displayed in the dialog box, however, the user may key in a different range.

• Define the attribute information for Existing Ground Line and Proposed Fin-ished Grade.

• Select Apply.

GEOPAK opens the 2D cross section file and begins creating 3D complex line strings from each cross section. Each 2D cross section will highlight as the line string is formed. This gives the user a brief opportunity to check for errors. When the process is complete, GEOPAK returns to the 3D file to draw the Cross Sections.

A visual inspection of the 3D Cross Sections should be performed to verify their integrity. The colors of the 3D line strings should reflect the same colors as shown in the 2D design cross section. If an error has occurred, the user should return to the 2D design cross section file and fix the appropriate cross section(s) using GEOPAK and/or MicroStation. Delete the 3D Cross Sections and repeat the 3D cross section process to revise Cross Sections.


CHAPTER 6 3D Modeling Interpolation Between XS

6.4.3 Interpolation Between XS

Two Methods exist for interpo-lating Cross Sections:

• Longitudinal - used when a 2D plan view is referenced to the 3D cross section file. This is the only method sup-ported.

• Surfaces - should be selected when your plan view reference file is a 3D file.

• Beginning / Ending Station - values define the station range where surfaces will be gener-ated and Offsets will define the width. Data can be typed into the fields or entered by utiliz-ing the Station and/or DP buttons. The data for station and offsets can be filled in all at once by selecting the Station button and then data pointing on a 3D cross section.

• Highlight Applied Breaklines - will highlight the breaklines used in interpolation when toggled on.

Select the Draw Surfaces bar at the bottom of the dialog box to begin the interpolation process. The user is encouraged to process a small range of Cross Sections until the entire project has been done. When GEOPAK interpolates 3D Cross Sections, it projects like color to like color between Cross Sections. All MicroStation elements should maintain a consistent color scheme throughout the project. For example, within a 2D file, all ditch slopes should be drawn the same color and roadway lines should also be drawn using one color. If colors do not correspond, you will get a “Color Mismatch” error and the process will terminate. There are two ways to correct this error:

• check the Cross Sections for an inconsistent color scheme, correct any errors, then regenerate the necessary Cross Sections.

• or activate the Force Color toggle; this will allow GEOPAK to ignore the color of the cross section elements and interpolate using only the specified color.

After interpolation is complete, review the 3D model using GEOPAK Drive Through.

See dialog box on next page.


CHAPTER 6 3D Modeling GEOPAK Drive Through

6.5 GEOPAK Drive Through

GEOPAK Drive Through provides the user realistic visualization of 3D surfaces. From the 3D Tools toolbox select the Drive Through icon.

The user must enter the Job Number and a Chain Name. The drive through will follow this chain or may be offset from the chain by entering a value in the Plan View Offset.

• Constant Elevation - will place the driver at a fixed elevation, as defined by the user, throughout the drive through process.

• Vertical Elevation - places the driver at a specified distance above the model, meaning the elevation of the view changes with the elevation of the model.

• Station - value will automatically display the beginning station of the selected chain and can be changed by user key-in.

• Step Increment - defines the distance traveled between each camera view.• Target Offset - defines how far down the road the viewer is looking (the focal point).• Locate Starting Point - will find the first station on the alignment where a 3D graphic ele-

ment is present. This is a convenient way to locate the start point of the 3D model.

• View - user indicates the MicroStation view to be processed.• Apply - activates the first camera view. Once the first view is displayed, the user may pan

the view by moving the slide bar to the desired angle and pressing the Apply button again.

After viewing the model:

• restore the view by typing vi=top in the MicroStation command window and select the appro-priate view.

• access the Settings >> View Attributes dialog box from the MicroStation command window and toggle Camera off (automatically toggled on during drive through process).


CHAPTER 6 3D ModelingExercise

EXERCISE 6.1In this exercise you will create and interpolate 3D Cross Sections to generate a 3D model, then view the model using Drive Through.

Step 1 Enter txdotv8iseed3d.dgn and Save As the file 3dxs.dgn

a. Access the 3D Modeling Toolsb. Complete the 3D Alignments

dialog box as shown to produce a 3D line string that will govern ver-tical curvature of the model.

c. Select Apply.

Step 2 Generate 3D Cross Sections.

a. Access the 3D Modeling Toolsb. Complete the 3D Cross Sections dialog box as shown.c. Select Apply.





Step 3 Open plan.dgn.

Using the D&C Manager and Draw Transition draw the outside edge of shoulders 34’ Left and Right of chain base1.

The outside edge of shoulder will be used as a break line for interpolation of the B-Splines to obtain a better representation of curved surfaces.

Step 4 Enter 3dxs.dgn and attach plan.dgn as a reference file.

a. Set the reference file levels to display only the centerline and edge of shoulderb. Fit All, then save the settings of this file.

Step 5 Open the Interpolate Between XS dialog box and complete as shown below:




Step 6 Turn display off on reference file plan.dgnView the model using Drive Through.

Step 7 Experiment with different display parameters when viewing the model.(For example: Phong Rendering and/or color schemes).


CHAPTER 6 3D Modeling Pavement Markings

6.6 Pavement Markings

Pavement Markings

This tool places pavement markings in a 3D file by extracting graphic information from the plan view of a 2D file.

Note: Pavement markings created with the D&C Manager or created with complex ele-ments must be dropped before they can be included in a 3D model. (For example: solid edge of travelway stripe)

Select the name of the 2D reference file containing the pavement markings.

• Search Criteria - the graphic attributes of the pavement markings.

• Stripe Width - reflects the actual width of the plan view stripe you want to create.

• Surface Elevation Offset - the distance from the B-Spline surface the stripe shape is drawn. Special attention needs to be applied to this value. If the distance is too low, the stripe may fade into the roadway; if the distance is too high, the stripe may cast a shadow on the road surface when the model is moved to a visualization software. It is desirable to place the stripe just above the surface. Begin by using a value of 0.10; if adjustments are necessary, use small increments.

Pavement Markings may be applied to an entire view or a fenced area by selecting the appropriate option. If view is chosen, be sure to fit the view before processing.

Input File Creation

Input file creation is an integral part of GEOPAK roadway design. Specific input files may be created which, when processed by GEOPAK, incorporates design information into the project.

The following pages provide examples of input files used for processing:• Proposed Cross Sections• Profile from Cross Sections• Slope Stakes• Earthwork

Comments may be inserted into an input file by enclosing the statement within distinctive symbology (/* ... */). This is an excellent method of making personal notes and its use is highly recommended Comments can be helpful in tracking revisions and helps clarify information when a project is shared between multiple designers.

Example: /* This line will not be executed by GEOPAK because it is properly enclosed. */

Conventions Used In This Document :

Bolded text represents the actual contents of an input file.

Italicized text provides an explanation of the corresponding line of input.

Three symbols are used to indicate the priority of input information:

<R> Required input as requested by GEOPAK<O> Optional input as requested by the user<N> Needed input as requested by the user. As the user selects optional

input items, some may require more information for GEOPAK to properly identify the item.

# indicates a numeric value is required
