Supports, Chairs, and Tolerances Proper support systems keep bars at required elevation and spacing. CRSI provides guidance on types of supports (wire chairs, precast concrete supports, bolsters, bar supports) and their placement frequency. Supports must be positioned to prevent movement during concrete placement and finishing. Placement tolerances—permissible deviations from specified location—are defined to allow practical placing while protecting structural performance; common tolerances relate to bar spacing, cover, and alignment. Inspectors verify tolerance compliance before concrete placement.
Proper concrete cover protects reinforcement from corrosion and ensures adequate bond. According to CRSI, bar supports (chairs, bolsters, spacers) hold the rebar in place to achieve the specified depth of cover. The manual also references ANSI/CRSI RB4.1, the standard for reinforcement supports, ensuring that chair and bolster usage aligns with industry-accepted specifications for maintaining clearances under live loads and during concrete placement.
CRSI does provide a wealth of free industry-trusted technical and reference information. These are excellent companion resources to "Placing Reinforcing Bars" and can be downloaded at no cost from the CRSI store. Crsi Placing Reinforcing Bars.pdf

Reinforcing bars are steel bars used to add strength and stability to concrete structures. They are made from a variety of materials, including carbon steel, stainless steel, and epoxy-coated steel. Reinforcing bars come in different shapes, sizes, and grades, each designed to meet specific construction requirements. Supports, Chairs, and Tolerances Proper support systems keep
Q: What is the purpose of reinforcing bars in concrete structures? A: Reinforcing bars provide tensile strength, durability, and resistance to cracking in concrete structures.
One of the most referenced sections of the CRSI manual is the tolerance section. How far out of place can a bar be before it becomes a structural issue? According to CRSI, bar supports (chairs, bolsters, spacers)
