Quick Answer: How is cut and fill calculated in Civil 3D?

How is cut and fill volume calculated in Civil 3d?

Solution:

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

How is fill amount calculated?

Record your dimensions in inches. For example, suppose that the length is 10 feet (120 inches), width is 5 feet (60 inches), and depth is 2 feet 6 inches (30 inches). Calculate the volume of dirt needed to fill the area you measured by multiplying length (120 inches) by width (60 inches) by depth (30 inches).

What is cut factor and fill factor?

n Cut factor: Compensates for the expansion factor of the material left after the cut. n Fill factor: Compensates for the compaction factor of the fill material. For example, for a material that expands 15 percent, type the value 1.15.

How do you get volume in Civil 3D?

To calculate volumes in Civil 3D 2014: After creating your ground surface and your graded surface, click the Analyze Tab → Volumes and Material Panel (as shown above).

Is cut and fill expensive?

Costs. Builders say that putting a concrete slab on a cut and fill site is cheap, and it is until you factor in extra costs to solve the drainage problems that occur after the builder has long gone. Putting in drainage after completion of the home is very expensive.

How is cut off marks calculated?

Cutoff marks are calculated by converting the Maths marks to 100, Chemistry marks to 50, Physics marks to 50 and then adding them up. The cutoff total marks will be a maximum of 200.

How many tonnes does it take to fill a hole?

The weight of soil can vary enormously based on the volume of water it contains. One cubic metre of moderately damp soil (as freshly dug) soil weighs 1.3- 1.7 tonnes when dug, depending on how tightly packed it is.

How do you calculate backfilling?

Backfill for Figure 3.1:

  1. Backfill volume = excavation volume – footing volume – wall volume. …
  2. (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”)
  3. Backfill volume = 207.4 cubic yards.

How do you calculate shrinkage factor?

Subtract the final size from the original size to find the amount of the shrinkage. For example, if a felt square shrinks from 8 square inches to 6 square inches, subtract 6 from 8, resulting in 2 square inches of shrinkage. Divide the amount of shrinkage by the original size to find the shrinkage rate.

What is the compaction factor for gravel?

Conversely, material typically shrinks under compaction.

Typical bulking & compaction factor chart.

Material Typical Bulking Factors Typical Compaction Factors
Sand & Gravel 1.12 0.88
Rock (blasted) 1.5 1.3

How do you calculate soil bulking factor?

To use a bulking factor number you have to multiply the bulking factor number by the excavated volume size. If your excavation was 15 m3. You must consider the bulking factor of the material you are digging to ensure you correctly plan for the removal costs and time to do it in.
