In this exercise you’ll review the options that are available for quantity takeoff criteria and reports the quantity takeoff report settings include the default quantity takeoff criteria used to create material lists and default styles for tables the quantity takeoff criteria includes a list of materials that specifies the surfaces and shapes from which you want to generate volume information let’s start by reviewing quantity takeoff settings go ahead and open up your earthworks-1 drawing in your tutorials folder now when the drawing opens you’ll see three different viewports let’s start by first going into our tool space and then clicking on the settings tab go ahead and expand the quantity takeoff and then under the commands collection double-click on the generate quantities report you’ll see within this dialog box we have a list of settings in here that you can go ahead and browse through but don’t change anything once you’re finished looking at these settings you can go ahead and click cancel now let’s examine the quantity takeoff criteria go ahead and go back into your settings tab and then under quantity takeoff we’ll expand the quantity takeoff criteria now there are three Styles defined in this collection double-click on Earthworks
now go ahead and click on the material list tab now this tab contains a predefined table for calculating Earthworks such as cut and fill by comparing the datum surface layer to an existing ground surface layer go ahead and expand the Earthworks table you’ll use the Earthworks criteria in the next exercise to calculate the quantity takeoff notice that the condition for the EG surface is set to base while the condition of the datum surface is set to compare this indicates that the material is going to be fill when the datum is above EG and cut when datum is below EG also note that there are three Factor columns within this table the cut factor is typically used as an expansion factor for excavated material it’s usually one or higher The Fill Factor is typically used as a compaction factor for fill material it’s usually one or higher the refill Factor indicates what percentage of cut material can be reused as fill it should be one or lower go ahead and click cancel so that’s how you go about reviewing quantity takeoff criteria and Report settings in civil 3D in this exercise you’ll create a material list which defines the quantity takeoff criteria and surfaces to compare during an Earthworks analysis a material list is required to generate either an Earthworks volume report or a mass Hall diagram a material list specifies the existing ground and datum surface to compare and is saved with the sample line properties this exercise continues from reviewing quantity takeoff criteria and Report settings so let’s go about creating a material list go ahead and open up your Earthworks dash one drawing in your tutorials folder now when the drawing opens you’ll notice that there are three viewports go ahead and go up to the analyze tab and then over to the volume and materials panel select compute materials
in the select sample line group dialog box specify the following parameters the alignment that we’re going to select is the center line [Music] and for the select sample line group we’re going to leave it at its default slg-1 I’ll go ahead and click ok
the compute materials dialog box is now displayed showing a list of all the items defined in the selected criteria now verify that the quantity takeoff criteria is set to Earthworks in a table make sure that surfaces has been expanded this shows surfaces EG and datum next you’ll set the actual object names that define those surfaces in the object column for EG go ahead and click the Box and select EG from the list
now next to datum
select Corridor datum in the earthwork criteria settings EG is set as the base surface and datum is set as the compare Surface the object name fields specify Which object calls for both an EG surface as the base and a datum surface as the comparison this criteria can be used with multiple projects and corridors the object name fields in the compute materials dialog box Define a specific surface and Corridor surface to map to the names in the Earthworks criteria go ahead and click ok
in the drawing notice the cut and fill areas in each section are shaded hover your cursor over the shaded areas and notice the information that’s displayed so that’s how you go about creating a material list in civil 3D in this exercise you’ll use the Earthworks criteria to generate a quantity takeoff report this exercise continues from creating a material list so let’s start by generating a volume report go ahead and open up your earthworks-2 drawing in your tutorials folder now when you do that you’ll notice that we have three different viewports go ahead and click on your analyze tab then within the volumes and materials panel click volume report
in the report quantities dialog box specify the following parameters we’ll keep the alignment at its default as well as the sample line group we’ll also keep the material list at its default now this list is the list you created in the creating a material list lesson by calculating volume quantities for the sample line group using the Earthworks criteria so now we’re going to select a style sheet go ahead and select the folder
and select earthwork
click open
now make sure that the display XML report checkbox is checked click ok the volume report is now displayed the cut volume is the area of material in Cut multiplied by the cut Factor defined in the quantity takeoff criteria the fill volume is the area of fill material multiplied by The Fill Factor the areas for each material are average between stations and multiplied by the station difference to produce the incremental volumes these volumes are added from Station to Station to produce the cumulative volumes finally the cumulative net volume value at each station is calculated as the cumulative reusable volume value minus the cumulative fill volume value so that’s how you go about generating a volume report in civil 3D
