Revit reports the values by making a comparison between a surface from one phase and, from a later phase, another surface whose boundary lies within the earlier surface. If you are given a shrink factor of 0.20, use 0.80 in the equation so that the soil becomes 20% smaller. Report the cut and fill volumes of the graded region with a topography schedule. It is less volume than the in-situ condition due to it being more compacted than when it was at rest and is much less than the in-situ volume.

There is a risk associated with cutting and filling the land specifically . <> Different methods of calculation are adopted for different kind of […] Today, most owners, engineers and architects request excavation bids based on the cubic yards . While using the Grid Volume Method for producing Cut and Fills we wanted to include the volume correction factor of 0.85 for fill (fill will campact to only 85% of what is used). . I don't like how the books show how to use these factors, the equations I have seen have the factor on one side and a fraction on the other. In the final step, the calculation of cut/fill areas for each. For this reason I don't even remember the division equation. If the material is ordered by the ton, identify the weight per CF of the material and multiply it out. MudShark will produce fast, and accurate calculations, with purpose built intelligent takeoff tools, interactive visualisations, and so much more. 3.
