The volumes determined from the grading object not include interior features of the parking lot, such as the raised curb islands and the building pad area For more accurate volume calculations, volumes can be calculated using a surface, as described in the next topic Calculating Earthwork Volumes for a Grading Site For the project in this lesson, which includes multiple grading objects and breaklines, calculating composite volumes using a surface provides a practical method For other volume calculation methods, refer to Lesson 17 of the Land Desktop Tutorial Before you can calculate volumes, you need to define a stratum and a site - On the View menu, click Named Views to display the View dialog box Under Name, select Site Definition, and click Set Current Click OK - On the Terrain menu, click Select Current Stratum to display the Define Stratum dialog box - Enter Parking1 for the Name and Gross Volumes for the Description - Click Select for Surface to display the Select Surface dialog box select ExistingGround, and then click OK - Click Select for Surface to display the Select Surface dialog box, select Proposed Surface, and then click OK - Verify that Surface is ExistingGround and Surface is Proposed Surface, and then click OK to continue - On the Terrain menu, select Site DefinitionSite Settings to display the Volume Site Settings dialog box - Verify that the Suffix is cu yds., and click OK - On the Terrain menu, select Site DefinitionDefine Site 10 - Press ENTER to accept a rotation angle of 11 - Select a base point that is south and west of the parking lot (i.e., one that is below and left of the grading limits displayed on the screen) 12 - Enter 50 for the Grid M size, and press ENTER to accept 50 as the Grid N size (Since this site contains relatively flat slopes with no abrupt changes, a 50x50 grid was specified For greater accuracy, particularly in rougher terrain, you may wish to specify a denser grid.) 13 - Select an upper right corner that is north and east of the parking lot (i.e., one that is above and right of the grading limits displayed on the screen) Click here for an illustration of the site outline 14 - Press ENTER to accept the default, No, to changing the size or rotation of the grid, and press ENTER to accept the default for erasing old site outlines 15 - Enter Site1 for the Site name With the site defined, you can proceed with volume calculation 16 - On the Terrain menu, click Composite VolumesCalculate Total Site Volume to display the Site Volume Librarian dialog box 17 - From the Select site list, select Site1, and then click OK to display the Composite Volume Settings dialog box 18 - Accept the default values in this dialog box by clicking OK and displaying the Volume Results Surface dialog box (If you wished to apply shrinkage or swell factors on your project, you would adjust these values here.) The "Current composite surface is Site1 - Gross Volumes dialog Nha Trang 04-2008 Duy Cò Autodesk Land Desktop and Civil Design Tutorial 83-85 box" is displayed after you accept the default values in the Composite Volume Settings dialog box Click Yes to use a different surface The Volume Results Surface dialog box is displayed 19 Enter Site1 - Gross Volumes for the New surface, and then click OK The composite volume calculations are displayed on the command line, with a cut volume of 130 cu yds., a fill volume of approximately 4470 cu yds., and a net volume of approximately 4340 cu yds of fill Balancing Earthwork Volumes As you can see from the previous steps, the fill far exceeds the cut for this project To balance these volumes, you could lower the proposed surface incrementally using a trial-and-error approach, but Civil Design offers a better alternative: the Balance Volumes command This feature can be used to raise or lower grading objects a uniform amount to achieve a desired net volume - On the View menu, click Named Views to display the View dialog box Under Name, select Parking Lot, and click Set Current Click OK - On the Grading menu, select Slope GradingBalance Volumes - When prompted to select a grading object, pick one of the blue projection lines around the perimeter of the parking lot (You can pick any part of a grading object, including the footprint, daylight line, or projection lines.) The Initializing Balance Volumes dialog box appears momentarily, followed by the Balance Volumes dialog box - Enter a Volume Result of (zero), a Cut/Fill Tolerance of 50, and then click Calculate The Calculate button changes to a Stop button that enables you to cancel the process while iterations are being performed After completion, the number of iterations is shown, along with the results of the Balance Volumes command The values specified in the previous step result in a net volume of approximately 38 cubic yards, indicating slightly more fill than cut The new base elevation is approximately 1005, or approximately 1.3 feet lower than the original base elevation of 1006.32 At this point, the grading object has been updated on the screen to reflect the numbers shown in this dialog So far, you have been working only with the finished surface of the proposed conditions, and have not accounted for pavement and subgrade materials imported to the project For this project, assume you have a 4-inch pavement section and an 8-inch gravel section This means that the grading surface is actually foot below the finished surface Under these conditions, the finished surface only needs to be lowered approximately 0.3 feet to achieve balanced earthwork conditions While the Balance Volumes command helped determine the adjustments needed to balance earthwork, you will not want to save the modified grading object Rather you can adjust the grading object downward 0.3 ft using another approach demonstrated in the next topic - Select Cancel to exit the dialog The grading object reverts back to its original state (If you wanted to keep the modified grading object, you would press Accept.) Note The above assumes no swell or shrinkage of on-site materials If conditions warrant applying these factors, you will need to adjust volumes accordingly, as discussed in the previous topic, "Calculating Earthwork Volumes for a Grading Site." Making Adjustments to Grading Designs Based on the results of the Balance Volumes command, the finished surface needs to be lowered approximately 0.3 feet to achieve balanced earthwork conditions Civil Design allows you to raise or lower grading objects incrementally by simply selecting the grading object and pressing Ctrl + or Ctrl -, respectively - On the Grading menu, select Slope GradingGrading Properties - When prompted to select a grading object, pick one of the blue projection lines around the perimeter of the parking lot to display the Grading Properties dialog box - On the Footprint tab, change the Elevation Step to 0.30, and click OK This means you can step the elevation of the grading object up or down in 0.3-foot increments - Again, select the grading object by picking one of the blue projection lines around the perimeter of the parking lot With the grading object highlighted, hold down the Ctrl key and press the - (minus) key (You must use the - key on the numeric keypad, not the one at the top of the keyboard.)
