How do you use cut and fill method?

With this method, cross-sections of the existing and proposed land levels are measured at regular intervals across the site. The cut and fill area is determined for each cross-section, then adjacent cross-sections are compared and the averages of their cut and fill areas are multiplied by the distance between them.

How do you calculate earthwork in a filling?

Volume = Sum * 100 (Area of Each block) = 4.6225 * 100 = 462.25 (Filling).

How do you calculate backfill and excavation?

Backfill for Figure 3.1:

Backfill volume = excavation volume – footing volume – wall volume.
(Note that only the portion of the wall that is in the trench is deducted, so the height of wall in the trench is the average trench depth minus 2′-0” for the footing: 6′-0” – 2′-0” is 4′-0”)
Backfill volume = 207.4 cubic yards.

How do you create a cut and fill map in Civil 3D?

Solution:

On the command line type “COMPUTEMATERIALS”.
Select the alignment and sample line group to sample, then click “OK”.
Change “Quantity takeoff criteria” to “Cut and Fill” or other desired criteria.
Map the sampled surfaces to the correct object names, then click “OK”.

How is earthwork cost calculated?

The cost of excavation is generally estimated by multiplying the total excavation volume to the excavation price per unit. For ex : Let us assume that you want to excavate a pit of size : 2 x 2 x 2 meter. The market price for excavation is 10$/cu. m.
