GeoPak Road 2 Earthwork: Rock Excavation

End Area Volume tool: Rock Excavation Exercise

Rev. 3-24-17 Missouri Department of Transportation 1

1. Open the following MicroStation file:

/Cole/J5U0441G/data/J5U0441G_Terrain_Existing.dgn

2. Import the RTE179_Existing_Ground.TIN file using the Create From File.

Filter = US Survey Feet Feature Definition = Existing Boundary

3. Create a new 2D Power Geopak file and name it J5U0441G_Civil_Geometry.dgn

4. Import the Route 179 chain and profile from the 441.gpk using the Import Geometry tool in the General Geometry tool set.

Drill down the “plus signs” until you get to Profile where you will select RTE179PR which

will select the alignment as well.

Verify that the Create Civil Rules is toggled on then select Import.



5. Change the Feature Definition of the alignment to Geometry Scratch by selecting the alignment and hovering for the heads up display.

Select the Properties and drill down through Design > Drafting Standards > Plan > Alignments > MoDOT_Baseline_Proposed

6. (Optional) Using the D & C Manager “paint” the stationing on the chain if the feature definition MoDOT_Baseline_Proposed wasn’t used.

7. Create a new 2D Power Geopak file and name it J5U0441G_Corridors.dgn

8. Reference in the following files:

J5U0441G_Civil_Geometry.dgn

J5U0441G_Terrain_Existing.dgn



9. Set the RTE179_Existing_Ground terrain as the Active Terrain using the heads-up prompts.

10. Using the Create Template tool open the template library J5U0441G.ITL located in the data folder.

11. Verify template “4 Lane Asphalt w/ Type C Barrier” is located in the J5U0441G folder

12. Create a corridor named RTE179 using the RTE179 horizontal alignment and the RTE179PR vertical alignment.

At this point we will use the Preliminary Design Stage

13. Use the “4 Lane Asphalt w/ Type C Barrier” template along the RTE179 corridor using the following information:

Start Station 62+00

End Station 138+00

Drop Interval 25

Transitions 0

14. Create a new 2D Power Geopak file and name it J5U0441G_Superelevation.dgn

15. Reference in the J5U0441G_Civil_Geometry.dgn file



16. Create a Superelevation Section using the RTE179 alignment naming it RTE179 From Station 42+00 to 62+00

Note: If a section is created for the entire distance desired the tool will create more than one section. You can delete all but one and dynamically stretch the section or key-in stations to

make it one section or create a shorter section and then expand it as shown above.

17. Create lanes (2 lanes) for the 4 lane highway as follows: Lane Name = North Lane Name = South

Side of Centerline = Left Side of Centerline = Right Offset = 0’ Offset = 0’ Width = 28’ Width = 28’

Normal Cross Slope = +2% Normal Cross Slope = -2%

18. Calculate Superelevation by using the T:\MoDOT_Workspace\GPK_Std\Superelevation\ english_2011.sep file.

19. Define the Calculate Superelevation dialog as follows:

Select the created shape and change the end station to 150+00.



20. Open the J5U0441G_Corridors.dgn file

21. Reference in the J5U0441G_Superelevation.dgn file

22. Assign the superelevation to the RTE179 corridor using either the heads-up prompts of the corridor or from the Task > Corridor > Superelevation tools.

23. Verify that the point controls of the superelevation are working properly by navigating through Dynamic Cross Sections of the RTE179 corridor

You should see 2 magenta points representing the superelevation point controls

24. Create a new 2D Power Geopak file and name it J5U0441G_XS.dgn


J5U0441G_Civil_Geometry.dgn J5U0441G_Corridors.dgn J5U0441G_Terrain_Existing.dgn

Note: Creating a 3D model and defining the Active Terrain is not necessary before running the Create Cross Section tool as the tool will automatically create the 3D model and

show the existing ground as defined by the Corridors file.



26. Create a Custom Cross Section model using the Stacked - XS Only preferences and the RTE179 complex element/ profile

Start Station = 62+00 Start Station = 81+00

Stop Station = 75+00 Stop Station = 138+00

Interval = 100 Interval = 100

Left Offset = -280 Left Offset = -280

Right Offset = 280 Right Offset = 280

27. Select Apply to process the cross sections and open a newly created cross section model containing cross sections per your preferences.

28. Open the End Area Volume tool.



29. Load the MoDOT-Earthwork preferences

30. Verify current view is the current Model and that the surfaces of RTE179_Existing_Ground and RTE179 are checked.

End Area Volume tool calculates between the surfaces to get the volume. Existing and Design are common but Substratum (rock) surfaces may be listed and used as well if there is a rock

surface present.

31. In the Classifications section of the dialog, adjust factors with the given parameters:

Existing Ground (terrain surface) Cut multiplication factor = 0.870000

Fill multiplication factor = 1.000000

Component (template component) Fill multiplication factor = 1.000000



32. In the Added Quantities section of the dialog, add the following Add Volumes to account for the bridge ends:

Type Station Volume Factor

Fill 75+00 8351 1.0000

Fill 81+00 5692 1.0000

33. Process the earthwork by selecting the Apply button

Note: The numbers are estimated since we are using template drops at 250’ drop intervals and

a Preliminary Design Stage.

Also, cross sections will have some proposed elements not tying to ground and ditches are not finishing because of the interpolation that is occurring from the template drop interval and

design stage settings. This will be addressed later in the project.



34. Once the XML Report has been generated you may need to change some format options from Metric to English stationing as well as a toggle that will convert to Cubic Yards.

35. Earthwork XML Report:

Cut: Unadjusted = 419404.1 Adjusted= 364881.6

Fill: Unadjusted = 464347.0 Adjusted = 464347.0

Mass Ordinate = -113508.4

Note: At this point, you would tweak your chain and more likely the profile until you get a closer earthwork balance. But for this exercise we’re going to continue on.

36. Save the MicroStation file.

37. The Soil Survey Report has just arrived (See next page)

38. With the Survey Soil Report in, we will take this information and create surfaces representing the rock with the next few steps.

First, we will be using the Excel file that has the borehole locations defined by station and offset.

Note: The Excel file will need to be created if given a physical piece of paper representing the soil report. In this exercise the Excel file has been created for you.

39. Create a new folder on the Desktop name it J5U0441G

40. Double click the file Borehole_Location.xls in the ProjectWise data folder to open the file in Excel.

41. Save the Borehole_Location.xls file as a CSV (comma delimited) file as Borehole_Location.csv to the desktop folder J5U0441G outside of ProjectWise

42. Rename the newly created Borehole_Location.csv file to Borehole_Location.brh extension.

43. Drag the Borehole_Location.brh file into your ProjectWise data folder

44. Next, we will be using the Excel file that has the borehole materials defined by depth and offset.

45. Double click the file Borehole_Material.xls to open the file in Excel.

46. Save the Borehole_Material.xls file as a CSV (comma delimited) file as Borehole_Material.csv to the desktop folder J5U0441G outside of ProjectWise



47. Rename the newly created Borehole_Material.csv file to Borehole_Material.mtl extension.

48. Drag the Borehole_Material.mtl file into your ProjectWise data folder

49. Continuing in the J5U0441G_XS.dgn

50. Choose the Geo Technical Tools from the Geopak/Road/Utilities menu or from the Geopak Road toolbox.

51. Create a new Geotechnical Data File by choosing File>>New. Name the file RTE179.gtd and place in the ProjectWise data folder

Job - 441

Ground Tin - RTE179 Existing Ground.TIN Toggle on Override user provided elevation using tin file.

Note: When the toggle is activated and the user enters an elevation when a TIN file has already been specified, the user entry is utilized. If the toggle is not activated, the TIN

elevation is utilized and the user entry is ignored.

52. Import the borehole location file Borehole_Location.brh by going to File>>Import>>CSV>>Borehole within the Borehole tool.

53. Import the borehole material file Borehole_Material.mtl by going to File>>Import>>CSV>>Material within the Borehole tool.



54. Create the material tin model as shown in the example below by selecting the Interpolating Subsurfaces Tin Files From Borehole Data tool.

55. Verify the material alignment, and adjust if necessary by changing the option to Material Tin and selecting the Modify button to impose changes.

Highlight the Rock material in the dialog, select Material Tin from the Tin Type pull-down

and click the Modify button to change the Tin type.

Select the Apply button to process the Material Layers into a new TIN file

56. Navigate using Windows Explorer to the local DMS folder (c:/users/caddusername/pwise_local_electronic_plans) that contains the newly created Rock.tin file.

Drag the Rock.tin file into your ProjectWise data folder.

57. Create a new 3D Power Geopak file and name it J5U0441G_Terrain_Rock_1.dgn



58. Open the Terrain Model task group and select the Create From File tool

59. Import the Rock.tin file using the Create From File.

Filter = US Survey Feet Feature Definition = Existing Boundary

Click the Import button to start the process of importing the selected files.

Fit the view

Note: The surface contains triangles that are connected from each area of the borehole locations that are not true triangle legs and need to be removed.

The following steps will remove the “bogus” triangles and create new more accurate rock surfaces to be used in earthwork calculations.

60. Remove the Civil Rules from the surface.

61. Drop #1 - Using the MicroStation Drop Element tool, select the surface and accept by data point in a blank area of the screen. This will drop the 3D surface to a MicroStation Mesh.

62. Drop #2 - Using the MicroStation Drop Element tool, select the mesh surface and accept by data point in a blank area of the screen. This will drop MicroStation Mesh to MicroStation elements.



63. Change the attributes of the elements by creating a Selection Set of all the dropped elements.

Color = White – MicroStation color 0

64. Remove the “bogus” triangle legs that connect the cluster of shapes (surfaces to be) together using the following steps:

Turn off the Graphic Group option

Using the MicroStation Delete Element tool to delete any bogus triangles as well as any triangles that shouldn’t be there according to the soils report

65. Create a new 3D Power Geopak file and name it J5U0441G_Terrain_Rock_2.dgn

66. Reference in J5U0441G_Terrain_Rock_1.dgn

67. Create individual surfaces of each cluster of shapes using the Create From Elements tool.

Set the dialog as follows: Feature Type = Break Line

Edge Method = Max Triangle Length

Max Side Length = 125

Feature Definition = Existing Rock Surface

Name = Rock Surface

68. Open the J5U0441G_XS.dgn and make the Default model the View 1 active model

69. Reference in the J5U0441G_Terrain_Rock_2.dgn




General tab:

Model Name = RTE179-Rock






Note: The reason we are using a left and right offset smaller than we will for the End Area Volume final cross sections is that we want the rock surface not to extend to the end of the

cross sections or it will cause errors.

Select the APPLY button to process

71. There is a minor issue concerning ProjectWise and the way it relates to Power Geopak causing a Log-In screen to pop up requiring your log-in credentials.

Exit Power Geopak and check all documents in.

72. Draw Pattern lines into the DGN using the Draw Pattern Lines from XS tool located in the Geopak pull-down>Road>Cross Sections>Draw Pattern Lines from XS.

This is done so we can utilize a legacy tool in Geopak that will allow us to extend our rock line.

73. Set the XS DGN File to J5U0441G_XS.DGN (the currently opened file) XS Baseline should populate automatically



74. Double click on the Symbology and set the level to Geopak-Pattern line 1

75. Click the Draw Pattern Lines button to place pattern lines in the model

Verify the pattern lines have been created and then close the tool.

76. The next step is to extend the Rock Line to the extents of the cross sections to create a rock surface for generating quantities.

In ProjectWise, right click on Extend Rock in XS.inp and select the Open With option and choose Notepad.

77. Verify and Edit the DGN definitions to J5U0441G_XS.dgn or the current file you are using. This should be done for each occurrence in the file (4 places).

Save, Close and Check-In the INP file

78. Open the Process Cross Sections tool from the pull down Geopak > Road > Cross Sections > Process Cross Sections



79. In the Process Cross Sections tool define the Name field with the Extend Rock in XS.inp file as shown below. Once the name field is defined then click the Apply button to run the INP file.

Note: This tool will locate the Rock Surface, copy the existing ground to the Rock Surface and

extend the rock line out to the ends of the cross section. If no Rock Surface is found, one will be created far below the existing ground. This will aid in

creating a complete Rock Surface.

80. Go through each cross section using the Cross Section Viewer searching for instances where rock protrudes above the existing ground or rock may be missing. Make adjustments if necessary.

81. A surface (or terrain) needs to be created out of the cross sections. Open the Reports tool from the Geopak > Road > Cross Sections > Reports pull down.



82. In the XS Reports dialog select DTM Proposed 3D tool.

The DTM Proposed 3D Report allows the user to create a DAT file representing the bore hole

rock surface that includes the added rock from the input file.

83. In the DTM Proposed 3D Report tool fill out the following: Job = 441

Chain = RTE179

Begin Station = 62+00

End Station = 138+00

84. Click the Existing Ground Line button: Check only the option for Weights on and set to 31

Note: The tool will not operate correctly if any elements are found but this input field needs to have something in it to run. That is the reason why we use a line weight of 31.



85. Click the Proposed Finish Grade button:

Check on the Lv Names, Colors and Styles

Select the Match button then select the 2 rock surface elements which will place the attributes of the element in the dialog. You can use the Display button to show the selected elements.

80. Fill in the following for the remaining dialog: ASCII File = RockSurface_XS.dat

Apply starts the process = A message in Message Center notifies completion of process

86. The DAT file has been created and placed in your job data folder.

87. Create a new 3D Power Geopak file and name it J5U0441G_Terrain_Rock_Final.dgn

88. Import the RockSurface_XS.dat file using the Create From File tool Filter = US Survey Feet Feature Definition = Existing Rock Surface



89. Change the Edge Method to Max Triangle Length and set the value to 125

90. Open J5U0441G_Corridors.dgn and Check-In the J5U0441G_Terrain_Rock_Final.dgn saving the changes made.

91. Reference in J5U0441G_Terrain_Rock_Final.dgn

92. Click the F6 key to open the View 2, Default-3D view

93. The template previously used for this corridor does not contain any benching options and now that we have added a rock surface we will need to add benching to our template. Open the J5U0441G template library.

94. Navigate to the J5U0441G folder, make a copy of the 4 Lane Asphalt w/ Type C Barrier and paste it into the same folder.

95. Rename the 4 Lane Asphalt w/ Type C Barrier1 to 4 Lane Asphalt w/ Type C Barrier Benching

Double click on the 4 Lane Asphalt w/ Type C Barrier Benching to place it in the edit window



96. Modify the template by adding the Benching component to the 4 Lane Asphalt w/ Type C Barrier Benching template

Mirror the component and place on the RT_Guardrail_Widening_B point

Note: In the Component Properties, Benching Count defines how many times the benching will occur before it stops and runs with the End Condition. Using a value of 0 (zero) will run the

benching with an endless count.

97. Add the End Condition Ditch Back Slope 1 to the end of the Benching and change the slope constraint to -50 % for the left side and 50% for the right side.

98. Verify the benching Target Type is set to Terrain.

99. Test the template and make changes to the priority of the end conditions.

Bench = 1 (highest) Ditch = 2 Fill Slope = 3 (lowest)

100. Exit the template library and save changes.



101. Select the Corridor, open Corridors Object tool and update the template drop to the newly created Benching template.

This will cause a reprocessing of the corridor. Close the tool afterwards.

102. Change the Design Stage of the RTE179 corridor from Preliminary to Final - x 1

Note: the Design Stage options appear grey and not seem to be an option but the reason it is

greyed out is because it resides in a DGNLIB. Once the desired preference is chosen it is written into the file and will appear in a black font.

103. You can verify the benching is showing up by turning the display of Terrain_Rock_Final_J5U0441G off in the Default-3D view.

104. Create a new 2D Power Geopak file and name it J5U0441G_XS_2.dgn



105. Reference in the following:


J5U0441G_Terrain_Rock_Final.dgn







107. Open the End Area Volume tool.

108. Load the MoDOT-Earthwork preferences

Final Layout: 89ft, 108ft, 125ft, 115ft, 125ft, 101ft continuous composite plate girder spans (using weathering steel). Use non-integral end bents with straight turn-back wings (11’ Lt and 16’ Rt. at Bent 1; 14’ Lt. and 12’ Rt. at Bent 7 from fill face to tip of wing).

Skew: Varies. Use 40.00d L.A. Bents l through 4 and 30.0d L.A. Bents 5 through 7.

Grade: PVI Sta. 83+09.04, Elev 608.04, -5.000% Bk, 5.000% Ahd, 1115.48 ft VC

Loading: MSl8

Present Bridge: None

Tie Station: 78+74.00 at C/L Bent 5.

Traffic Handling: Not applicable (New construction).

General Notes:

• Alignment is tangent with stationing and profile grade at the C/L of Route 179.

• Intersection of C/L Route 179 and C/L Frog Hollow Road at Sta. 79+29.92 (Rte 179) and Sta. 4+61.42 (FHR).

• Provide substructure f or future roadway width of 104.33ft and superstructure f or present roadway width of 84.65ft (roadway widths are symmetrical about the C/L Route 179). Provide 16-inch exterior safety barrier curbs and 25-inch double-faced median barrier curb at the center of the 14ft median (Bridge items).

• Placement of intermediate bents to avoid interference with the existing sewer line is not feasible due to horizontal clearance requirements at Frog Hollow Road as well as hydraulic restrictions imposed by the presence of a ''floodway'' at Wears Creek. As a result, the sewer line will need to be relocated.

• Provide 2:1 (normal) spill fill slopes. A 2ft rock blanket (Roadway item) is required at the south spill fill only. Place to a height of Elev 607.68 ft at Bent 7. The base of the rock blanket is to extend 13.12 ft along the ground line toward Wears Creek.

• Fill exception Sta. 74+34.76+/- to Sta. 81+02.94+/-

• Provide approach slabs for a roadway width of 104.33ft (Bridge item). Temporary barrier curbs across the approach slab to be provided as a Roadway item.

• Provide a horizontal clearance of 31.17ft from C/L Frog Hollow Road and a final minimum vertical clearance of 15.58ft (estimated future grade along Frog Hollow Road to be assumed to be -0.75% from Elev 603.67ft at Sta. 2+95.28 to Elev 601.21 at Sta. 623.36ft).

• Provide an opening of 32.81ft horizontal x 14.76ft vertical at Frog Hollow Road during construction.

• Right-of-Way as required for new construction.

• A June 15, 1981 NFIP flood study for Cole Co., MO (Panel 290107 0080) shows this construction site in an area subject to 100-year flooding. A ''floodway'' will be crossed by the new structure. The Bridge Division is to obtain the floodplain development permit.



Hydrologic Data: D.A. = 3.02 sq. miles (Rolling)

Design Frequency = 100 yrs.

Q(1OO) = 5559.94 cu feet/sec

D.H.W. = 604.99 ft

Estimated Backwater = 0.62 ft

113. Per the new information Bridge Memorandum we now know where the bridge starts and ends so we will need to add Key Stations to the RTE179 corridor.

Note: The reason we add key stations is that this will place a template drop at the location and when cross sections are cut the sections won’t be between stations causing interpolation.

114. Open the J5U0441G_Corridors.dgn. Select the RTE179 corridor and use the heads up display to choose the Create Key Station tool (or select it from the Corridor Modeling tool set)

Create a Key Station for the following stations:

74+34.76

81+02.94

**Verify in the Corridor Objects dialog that the stations are in fact correct as typed

115. Create a new 2D Power Geopak named J5U0441G_XS_Final_Rock.dgn and Check-In the J5U0441G_Corridors.dgn saving the changes made. Open the View 1, Default model





Terrain_Rock_Final_J5U0441G.dgn

117. Open the Create Cross Section tool and load the Sheet – 20 scale preference.

118. In the General tab name the cross section model RTE179-EW-FINAL

119. Open the Custom tab and define as follows:
