What is the official name of the technical reference source for placing slab bolsters published by CRSI?

The official name of the technical reference source for placing slab bolsters, published by the Concrete Reinforcing Steel Institute (CRSI), is indeed the Manual of Standard Practice for Placing Bar Supports. This manual is a crucial resource for construction professionals involved in reinforcing concrete structures. It provides detailed guidelines and best practices for correctly positioning slab bolsters, which are essential for ensuring that the reinforcement bars are held in place at the proper height during concrete placement.

This document outlines standards that promote not only the structural integrity of concrete elements but also efficiency in construction processes. Having a standardized practice helps to mitigate issues related to inconsistent placement, which can lead to complications in both the strength and durability of the concrete.

Other choices, while related to concrete construction, do not specifically focus on the placement of slab bolsters like the chosen answer does. The Manual of Standard Practice for Concrete Construction covers a broader range of topics, while the Standard Reinforcing Practices Guide may offer general reinforcement strategies. The Concrete Support Systems Manual addresses support systems in concrete construction but lacks the specificity regarding bar supports found in the correct reference. Therefore, selecting the Manual of Standard Practice for Placing Bar Supports reflects a precise understanding of the needed guidelines for slab bolster placement in concrete work.
