Tip of the Week – Length Volume (LVM)
In this edition of “Tip of the Week”:
I need to estimate the cubic yards of concrete for a footing and stem wall. Is there a way to do that?
The Linear Volume formula is used when the estimator needs to determine the cubic yards of material needed to cover a linear measurement. A common use for this tool would be estimating a footing or stem wall.
How to estimate linear volume:
The steps below involve estimating cubic yards (CY) of concrete for a typical foundation footing. These same steps would be used in estimating any linear foot area into a cubic foot measurement.
Important: To take full advantage of the volume feature, your template file (.pedb) must be updated with our latest DB updates if it is older than 9/22/15 (Our last software release date). For help with this, please contact PrebuiltML Support by emailing firstname.lastname@example.org
Step 1. Using the Segment or Linear Tool in the digitizer, draw the line where the concrete footing will be located, then select the application of “Foundation Footing” in the right click menu.
Step 2. In the right click menu, select the product of “Concrete (CY)” and any attributes required, ie. strength, admixture, finish, reinforcement, pattern or color by using the right arrow key. click “OK” when finished.
Step 3. In the right click menu, select the thickness and the width of the footing, in this example the width is 20″ and the thickness is 12″.
Project List: In the Project Lists, notice the Concrete Pack shows the Foundation Footing input field as 9’x12″x20″. The cubic yard output will show in the “Quantity” column.
