Calculate Rebar Quantity From ** Total Slab Area and Perimeter To calculate Total Area of a multi sided slab, ** first divide the shape into rectangles or squares. (as in example diagram) Multiply the 2 different side lengths of each rectangle to find individual areas, then add them together to find Total Slab Area.

## How do you calculate rebar?

Find out the total length of rebar. ** Multiply that length of rebar by the weight per length ** associated with the size of rebar that is used . To figure out the total length of rebar in a grid used in a slab, there are several factors: The dimensions of the slab (length, width and depth) The spacing of the rebar. The inset from the edge of the slab before the rebar is used.

To tie rebar that is intersecting in a grid pattern: Use a ** saddle tie. ** Hold either end of the wire and place it above your first piece of rebar – hold it, so both ends are of equal length. Loop both ends beneath the perpendicular piece of rebar below on either side.

Convert your longitude measurement into inches: 15 feet x 12 inches per foot = 180 inches. Divide your result by the spacing measurement: 180 in / 14 in = 12.87 (round up to 13)Add one rebar to your result: ** 13 + 1 = 14. **

## What is the cost per pound of rebar?

You can buy rebar by the pound, and it only costs between ** $0.70 and $1.25 ** per pound. Not all manufacturers sell rebar by the pound, and that is because of how confusing it can get. For example, depending on the thickness, density, and size of the rebar, 1 foot may equal 1 pound. However, for small or thin rebar, it may take 1 ½ feet to 2 feet to equal 1 pound of rebar.

The total cost for installing rebar is ** $1-$1.20 ** per square foot. This will translate to $500-$600 for a 500 square foot area. The labor for a 500 square foot is averaged at $280-$345. This is equivalent to roughly $62-$76.50 per hour. Other than labor there are materials and supplies that are needed to install rebar reinforcements.

** Standard steel bar ** rebar is one of the most common types of rebar. Deformed steel rebar is appropriately named, and it is quite deformed. Stainless steel is actually more expensive than the other types of rebar. Galvanized steel is another popular option for rebar, or galvanized steel are a few extra items to look into.
