**Overview **

This help article will help the reader in the use of the STACK concrete catalog, whether a veteran in the trade or a new employee with no construction experience. The STACK concrete catalog contains assemblies for all sorts of flatwork and foundation structures. Flatwork assemblies do not contain rebar items, so adding an additional rebar assembly may be necessary. Rebar-only assemblies are available that mimic a concrete counterpart. Not only are they good for rebar-only contractors, but also can be added for more complicated rebar configurations.

**Terminology **

We recognize that different regions use different terms for their trades. This list should help you better understand the choices STACK assemblies offer.

*Footer, Beam, Stem Wall*– As far as STACK assemblies are concerned, these terms are interchangeable. All refer to structures in the foundation with length, width, and depth measured using a Volume 3D or Linear takeoff.*Column, Pier*– these terms refer to concrete that typically has a larger vertical component, whether into the ground or supporting part of the structure above.*Continuous Rebar*– This is rebar that runs along the length of the footer or beam*Cages, Stirrups*– These terms refer to rebar bent into a circle or rectangle or U-shape surrounding and supporting vertical or continuous rebar.*Horizontal Rebar*- this refers to two different types of rebar, depending on the assembly. In the “Concrete Wall – 3D” assembly it refers to rebar that runs along the length of the wall and spaced evenly going up the wall. In footer and beam assemblies, horizontal rebar sits perpendicular to the continuous rebar with length approximately equal to the width of the footing or beam. This type of rebar is sometimes called transverse rebar or cross-bridging.*Bar Lap Count*– the number of rebar diameters needed to make up the splice length. This is often confused with the splice length itself. The equation to determine this number is Rebar Diameter X Bar Lap Count = Splice Length. For example, if we have #4 rebar and a 2 foot splice length, our equation is .5 X Bar Lap Count = 24 then Bar Lap Count = 24/.5 = 48.
