Concrete Footing Calculator

Using the Concrete Footing Calculator

This guide outlines the steps you need to follow to accurately calculate your concrete footing requirements using the Concrete Footing Calculator. Follow these steps carefully to ensure precise results.

Step 1: Enter Footing Dimensions

• Footing Length: Enter the length of the footing in feet. This value must be between 0.1 and 1000 feet and can be adjusted in increments of 0.1 feet.
• Footing Width: Enter the width of the footing in feet. Ensure the width falls between 0.1 and 100 feet, with similar increments of 0.1 feet.
• Footing Depth: Enter the depth of the footing in feet. The depth must be between 0.1 and 20 feet, adjustable by 0.1 feet increments.

Step 2: Select Concrete Type

Choose the type of concrete based on its PSI (Pounds per Square Inch) requirement. Available options range from 2,500 PSI to 4,500 PSI, allowing you to select the strength suitable for your project.

Step 3: Choose Waste Factor

Select a waste factor to account for any possible excess material required. Options include:

• 5% waste (Factor of 1.05)
• 10% waste (Factor of 1.1)
• 15% waste (Factor of 1.15)

Step 4: Review Calculated Results

After inputting all the necessary information, review the resulting calculations appearing in the output:

• Volume (Cubic Feet): This is the total volume of your footing in cubic feet based on the provided length, width, and depth.
• Volume (Cubic Yards): This is the total volume converted to cubic yards for ease of use in concrete calculations.
• Volume with Waste Factor: This calculation gives the adjusted volume with your chosen waste factor applied.
• Bags of Concrete Required: Determine the number of 94 lb bags required to meet your project’s needs, with all factors accounted for.
• Estimated Cost: View an estimated cost for the concrete, calculated based on the number of bags required, at a cost rate of $5.50 per bag.

Conclusion

By following these steps, you will effectively use the Concrete Footing Calculator to estimate both the material requirements and costs for your concrete footing projects. This tool simplifies the calculation process, ensuring accuracy and efficiency in planning your construction needs.
