How to Accurately Assessing Erosion Control Materials
Erosion control is an important part of many construction projects. If not done properly, erosion can cause serious damage to the environment and to property. In order to ensure your project meets all requirements for erosion control, it’s important to accurately estimate how much material you will need.
2D Construction Plan Sheet or 2D CAD Measurements
As a construction professional, you know that one of the most important aspects of your job is ensuring that the materials you use are properly measured and accounted for. This is especially true when it comes to erosion control, as even a small mistake can lead to serious environmental damage.
Fortunately, there are a number of ways to accurately calculate the quantity of materials needed for erosion control, including using measurements from either a 2D construction plan sheet or 2D CAD file. Here's a step-by-step guide on how to do it:
- First, identify the area of land that will need erosion control materials.
- Once the area has been identified, measure the length and width of the land in question. This will give you the square footage you'll need to work with.
- Next, determine the type of erosion control material you'll be using. This will affect the volume of material needed, as well as the weight (and therefore, cost) of the project.
- Once you know the type of erosion control material you'll be using, calculate the volume required by multiplying the length, width, and depth of the area in question. For example, if you're using a material that is 1 foot deep and you have an area that is 100 square feet, you would need 100 cubic feet of material.
- Finally, convert the volume into weight by using a simple conversion chart. This will give you the approximate amount of material needed for the project, which you can then use to place your order.
Slope Area 3D View Calculation and AreasThis method uses measurements from the slope area 3D view calculation and areas for trenching, material overlaps, and waste. To calculate the quantity of materials needed for erosion control, first determine the area of the slope that will require protection. This can be done by measuring the length and width of the slope or by using a topographical map, as in the previous method. Once the area to be protected is known, calculate the volume of erosion control material required by multiplying the length by the width by the depth of coverage desired.
Next, calculate the amount of waste generated by trenching, overlapping materials, and other factors. Trenching waste is typically 10-15% of the total volume excavated. Overlapping material waste can vary widely, depending on the type of material used and the method of installation. For example, when using rolled erosion control products (RECPs), waste can be as high as 30%.
Calculating material waste, trench area, and material overlap needed for erosion control purposes can be a complex task. However, there are some basic guidelines that can be followed to ensure that enough materials are used to effectively control erosion.
Trench Area, Material Waste, and Material Overlap
The first step in calculating material waste, trench area, and material overlap is to determine the size of the project area. The project area is the total area that will be affected by erosion. This is what was calculated in the previous two methods.
After the amount of material needed has been calculated, it is important to determine the trench area. The trench area is the portion of the project area that will be excavated to accommodate the material. The size of the trench area will vary depending on the type of material being used and the depth of the excavation. A typical trench is 1 x 1 feet.
The material waste then needs to be accounted for, which is the portion of the material that will be lost due to installation damage, excessive curves, extra cuts, etc. A typical waste factor is 3-5%.
Finally, the overlap needs to be calculated. The overlap is the portion of the material that will extend beyond the trench area. This is necessary to ensure that the entire project area is covered and protected from erosion. A typical overlap is 3 inches.
By following these guidelines, you can be sure that you are using the right amount of materials to effectively control erosion in your project area.
When estimating erosion control materials for your next project, it’s important to get accurate measurements. You can do this by using a 2D construction plan sheet or 2D CAD measurements. By creating a 3D view of the slope and calculating trench areas, material waste and material overlap, you can ensure your estimate is as close to reality as possible. This will help you avoid any surprises when ordering materials, and ensure that you order enough to complete the job correctly, without over-ordering.
