Cross Sections: Creating, Annotating, and Volumes This workbook contains exercises to creating and annotating proposed cross sections as well as computing end-area volumes along a design corridor. In prior versions of our products, cross sections depicted an accurate representation of our modeled design as we all are generally accustom to. In the past, our cross sections tended to drive the design. With the advent of the OpenRoads Technology the cross sections now represent a byproduct of our proposed design model where the design 3D model now drives the design of our project.

Set the Start Station to 38+00 and the End Station to 70+00 and click Add. c. Select Added Quantities leaf settings. d. Set the Start and End Stations to 38+00, set the Type to Fill, enter a Volume of 11250 and a Factor of 1.2, and then click Add. e. Set the Start and End Stations to 70+00, set the Type to Fill, enter a Volume of 3750 and a Factor of 1.2, and then click Add. 14. Select Apply. This will complete the following five tasks when processing. Compute end areas. Compute volumes between sections. Label cross sections with computed values. Display cut and fill areas on the cross sections. Generate a quantities report that can be formated with Style Sheets. Create the Mass Haul diagram. Note: When the volumes computations are complete, the Bentley Civil report browser will open when the toggle is activated. The report browser allows the designer to review the end areas as well as computed volumes for all surfaces. 24
15. In the Bentley Civil Report Browser, select Tools > Format Options and change the Precision of Linear and Area Units to 0.12, also change the Cubic Units precision to 0. 16. In the report Browser, change to the Volumes.xsl report available on the left. 17. Scroll down to station 38+00 in the report and notice the Added Fill of 11250, the Cut/Fill Factors being applied, and the Guardrail components being ignored. 18. Dismiss the Bentley Civil Report Browser. 19. Dismiss the End-Area Volumes dialog. 20. Pan over to the right side of the cross sections to locate the generated Mass Haul diagram. Optional: Re-run the End-Area Volumes using a Forced Balance of Cut applied to station 54+00 and Fill applied to station 150+00. This will create a Mall Haul Diagram that forces the bridge span to have a cumulative volume of zero. You can delete the previous annotations and Mass Haul Diagram as they are placed on 2 distinct graphic groups. This will need to be done before running the End-Area volumes tool again. 25
Exercise 5: Volumes including Substratum Description In this exercise we will reference another Terrain Model in the design model, create a new cross section model that contains all surfaces, and compute the End Area Volumes. Skills Taught End Area Volumes Substratum Volumes 26
Volumes including Substratum 1. Continue in the End Area Volume.dgn. 2. Switch the Model to Substratum Cross Section. 3. Select the End Area Volume tool from the Corridor Modeling task menu. 4. Make sure to set the Cross Section Model to Substratum Cross Section on the End-Area Volumes dialog, and ensure that all 3 surfaces are checked on to compare (including Limestone). Why is it that the Substratum Cross Section includes a Limestone surface and the River Road Cross Section does not? Answer: The model containing the Limestone surface was referenced to the End Area Volumes.dgn after the River Road Cross Sections were created and before the Substratum Cross Sections were created. 27
5. Go to the Classification settings and set the Limestone Surface as a Rock Classification. 6. Click Apply on the End-Area Volumes dialog to create an XML Report and bring up the Report Browser. 7. Switch to the Volumes.xsl to see Limestone volume totals. 8. Scroll down to station 121+00 through 122+50. Also, examine the Cross Sections in that station range. 28
Optional: Examine the Road_Pave_Aggregate component volume at station 71+00 as well as the Normal Cut and Fill values at that station. Rerun the End-Area Volumes command with the Road_Pave_Aggregate component set to a Classification of MDC. 29
