The Foundations, Footers and Piers Calculator has functions that help estimate the amount of concrete needed for footers, foundations and concrete piers, for the amount of concrete to go around posts.

Foundations - Footers - Piers 

• Blocks in a Foundation: Computes the number of blocks needed for a foundation based on the dimensions of the foundation and the size of the blocks with a standard size mortar joint.
• Concrete in a Poured Foundation: Computes the volume of concrete, the square feet of the forms and the number of 4'x8's needed for the forms.
• Concrete in a Wall: Computes the volume of concrete in a wall based on the dimensions.
• Concrete in a Footer: Computes the volume of concrete for a footer based on the length, width and depth of the footer.
• Concrete in a Footer (Cross Section): Computes the volume of concrete for a footer based on the length and cross-section area of a footer
• Concrete in a Pier: Computes the volume of concrete in a circular pier based on the radius and depth of the pier.
• Piers for a Building: Computes the number of piers and volume of concrete need for the piers of a building (e.g., pole barn) base on the building dimensions, pier spacing, diameter and depth.
• Concrete around Circular Post: Computes the volume of concrete around a number of round posts in a round hole based on the size of the hole and dimensions of the post. 
• Concrete around Square Post: Computes the volume of concrete around a number of square post (e.g., 6x6) in round hole based on the dimensions of the post, depth and width of the round hole.
• Water Needed for Concrete: Computes the water volume needed to mix concrete.
• Price of Bulk Concrete: Computes the price of bulk concrete including delivery based on mileage and on-site pumping cost.
