The MASONRY suite includes collections of functions associated with product estimations on projects done with brick, block, concrete and rebar.

The following functions apply to estimating the amount of concrete, rebar, form boards and water needed for concrete slabs of different shapes: rectangular with squared corners, circular including semi-circle, and polygon shapes from triangular up (e.g., pentagon for 5 sides and dodecagon for 12 sided polygon).

**Rebar and Concrete in a Slab**: Computes the total length and weight of rebar and the volume and weight of concrete needed for a rectangular slab, taking into account the concrete displaced by the rebar.**Concrete in Rectangle Slab**: Computes the volume of concrete in a rectangle (squared corners) slab based on the dimensions. It includes the volume of concrete in cubic yards and the equivalent volume in bags of concrete. It also includes the surface area, length of form boards, and the water requirement.**Slab Weight**: Computes the weight, volume of concrete and surface area of a rectangle slab based on the length, width and depth of the concrete of the slab and the density of concrete.**Weight of Slab with Rebar**: Computes the weight of a rectangle slab with rebar based on the length, width and depth of the concrete of the slab, the density of concrete and the size and spacing of rebar. It includes total weight (concrete and rebar), and the contribution of weight from rebar and concrete separately.**Slab Area and Perimeter**: Compute the surface area and perimeter of a rectangular slab based on the dimensions.

**Volume of Circular Slab:**Computes the slab surface area, perimeter and cubic yards of concrete in a circular slab based on the diameter and depth. It also provides, the equivalent volume in 80lb, 60lb and 40lb bags of concrete and the water requirement.**Circular Slab Weight**: This computes the weight of the concrete in a circular slab based on the diameter, depth and density of concrete.**Rebar and Concrete in a Circular Slab**: This computes the length and weight of rebar in a rectangular slab. It also computes the total weight of the slab including concrete, taking into account the concrete displaced by rebar.**Semi-Circle Slab Volume**: Computes the volume of concrete needed for a semi-circular slab based on the radius and depth.**Semi-Circle Slab Weight**: Computes the weight of concrete in a semi-circular slab based on the radius, depth and density of concrete.

**Concrete in Polygon Slab:**Computes the surface area and cubic yards of concrete for a polygon slab based on the dimensions and depth. It also provides the equivalent volume of concrete in 80lb, 60lb and 40lb bags of concrete.

**Concrete Weight**: Computes the weight of a specified volume (e.g., 2.3 cubic yards) of concrete.**Price of Delivered Concrete:**Computes the price of delivered concrete based on the volume, price per cubic yard, pumping cost, delivery distance, and mileage.**Water Needed for Concrete:**Compute the amount of water needed to make a volume of concrete.**Concrete Displaced by Rebar:**Computes the volume of concrete displaced by a length of rebar based on the length and size of rebar.

**Brick or Block Wall:**Computes the number of brick or block needed for a wall based on dimensions.**Bricks or Blocks in a Wall**: Computes the number of standard U.S. brick or block needed for a wall using feet and inches.**European Brick or Block in a Wall**: Computes the number of standard European bricks or block in a wall using meters and centimeters.**Custom Stone in a Wall:**Computes the number of masonry units (stone, block or stone) in a wall based on the dimensions of the wall and the dimensions of the units and the thickness of the mortar joints. It also returns the number of rows needed and the number of stone per row.**Concrete, Rebar and Forms for Wall:**Computes the volume of concrete, amount of rebar and the surface area of forms for a concrete wall.

**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**: Compute the volume of concrete, the square feet of the forms and the number of 4'x8's needed for the forms.**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.

**Length of Rebar in Grid**: Computes the total length of rebar needed for one or more mats of rebar in a concrete slab based on slab dimensions, rebar spacing, inset from slab edge, number of mats, length of pre-cut rebar sticks, and a rebar lapping factor.**Weight of Rebar in Grid**: Computes the total length and associated weight of rebar needed for one or more mats of rebar in a concrete slab based on slab dimensions, rebar spacing, inset from slab edge, number of mats, length of pre-cut rebar sticks, a rebar lapping factor and the size of rebar.**Rebar and Concrete in Slab**: Computes the total length and weight of rebar and the volume and weight of concrete needed for a slab. The weight and volume calculations takes into account the concrete displaced by the rebar.**Wall (Rebar Concrete and Forms)**: Computes the length and weight of reinforcement bars (rebar) , volume of concrete and the surface area of forms for a wall based on the dimensions of the wall.**Rebar in an Irregular Shaped Slab**: Estimates the total length and weight of reinforcement bars (rebar) needed for an irregular shaped concrete slab**Rebar in a Circular Slab**: Estimates the total length and weight of reinforcement bars (rebar) needed for a circular shaped concrete slab.**Rebar Lapping Length**: Computes the length overlap needed at rebar joints based on rebar size and a lapping factor.**Rebar Cost Estimate**: computes the total cost of rebar based on the length being purchased, length of the individual pieces being bought and unit price of one piece of rebar.**Weight of Rebar**: Computes the total weight of rebar based on the length and size of rebar.**Concrete Displaced by Rebar**: Estimates the net weight added to a slab by adding rebar, and the reduction in concrete cause by adding rebar.**Weight of Slab with Rebar**: Estimates the weight of a rectangular slab with rebar base on the slab dimensions, rebar size and space and the know density of both concrete and rebar (steel). It also includes the individual weight of the components and the volume of concrete accounting for that displaced by rebar.
