How do you calculate cut and fill quantities?
Table of Contents
For each section line the cut area and the fill area is determined. The volume between two sections is determined as the average area of the two sections multiplied by the distance between them. By adding together the volumes between all of the sections the total cut and fill volumes are obtained.
What is cut and fill factor in Civil 3d?
For Cut and Fill Factor, let’s use 1.10. These factors control, depending on the soil type, how much the material swells after removal, or how much it is compacted when put in place. This means that for every cubic meter or feet of cut material we will need to haul 1.1 cubic meter or feet.
What is cut factor and fill factor?
The cut factor is used to adjust the volume of excavated material to account for the amount you expect the material to swell when it is excavated. The fill factor is used to account for the additional volume of material that would be required due to the compaction of the soil when it is placed.
What is cut fill analysis?
What Is Cut & Fill? In earthmoving, cut and fill analysis quantifies the amount of dirt to move in a project. That figure is essential in the bidding phase. Results of a cut and fill analysis often lead to discussions and plan adjustments.
What is cut and fill in construction?
In earthmoving, cut and fill is the process of constructing a railway, road or canal whereby the amount of material from cuts roughly matches the amount of fill needed to make nearby embankments, so minimizing the amount of construction labor.
How does the Civil 3D cut and fill tool work?
In fact, the Civil 3D cut and fill tool works very much as a surface elevation analysis. The only difference is that the analysed surface is not a standard TIN surface, but rather, a volume TIN surface. A volume TIN surface represents a volume contained between two surfaces.
How to create a cut and fill volume?
06-06-2017 01:06 AM Cut & fill volumes are generated by comparing two surfaces in civil 3d, normally an existing surface and a proposed surface. You need to create a surface from your existing topographical survey information and this will become your base surface.
How do I perform a cut and fill analysis?
To obtain an accurate cut and fill analysis, the first step is to become familiar with the Civil 3D surface analysis tool. In fact, the Civil 3D cut and fill tool works very much as a surface elevation analysis. The only difference is that the analysed surface is not a standard TIN surface, but rather, a volume TIN surface.
What is a tin surface in Civil 3D?
A volume TIN surface represents a volume contained between two surfaces. Therefore, before we can create a cut and fill volume in Civil 3D, we need to create two comparison surfaces. Generally, these two TIN surfaces will represent the existing ground, or EG, and the finished ground, or FG.
