Takeoff Report Error! - Material Quantities

  • 1.  Takeoff Report Error! - Material Quantities

    Hi all,

    I have noticed that the takeoff reports material quantities are not accurate at all. 

    For example;

    Surface Area    Depth (mm) Volume (m3)  
    Soft Landscaping 18693.9 m²      Calculated Total   TBC Total   Difference  % Diff
    Soils: Topsoil 18693.9   150 2799m³                               2,804             2,799                       5 0.18%
    Slabs 2131.6 m²       
    Paving: Slabs 2131.6   35 54m³                                     75                  54                     21 38.16%
    Aggregates: Sand 2131.6   25 29m³                                     53                  29                     24 83.76%
    Aggregates: Type 1 2131.6   100 211m³                                  213                211                       2 1.02%

    For example, 'Paving: Slabs' 

    Area 2131.6m2 * Depth 0.035m = Volume 74.606

    Trimble calculates this simple formula to 54m3.

    This is on numerous site improvement regions throughout the report generated in the 'Takeoff Report' button

    I assumed it could be calculating based on 3D area instead of plan, but I would assume that the % difference to plan would be consistent to each site region.


    2 AOIs used in this example, with the totals coming from the 'Total of all AOIs'
