The second booklet@ Cast-in-Place Walls covers formwork@ reinforcement@ placing of concrete@ curing@ and wall finishes.This third booklet is intended to provide construction knowledge for the apprentice@ journeyman@ and foreman involved with cast-in-place elevated slabs and beams. For the apprentice craftsman@ it provides a source of information to help supplement his practical experience. For the foreman@ it provides technical background on such topics as shoring@ reshoring@ form removal@ reinforcement placement@ and concrete placing@ finishing@ and curing. This booklet is not intended as a design aid@ but rather a guide to good practice. The design of supported slabs and beams is the responsibility of a professional engineer. Designs are usually reviewed and approved by local building authorities and governed by codes such as the Uniform Building Code@ Standard Building Code@ BOCA (Building Officials and Code Administrators) Code and others which reference ??Building Code Requirements for Reinforced Concrete?? (ACI 318).The selection and design of forrnwork is the responsibility of the contractor. The system selected must consider economics@ schedule@ quality@ and safety. If the craftsman is involved with the selection@ he must not assume responsibility beyond his level of experience. Poor selection may cost more money@ and more important@ may cause injury or death to fellow workers.While the craftsman is not responsible for the structural design of the slabs and beams@ he is responsible for good quality workmanship and a final product that meets the requirements of the job plans and specifications.Information in this booklet should be used as a guide to good practice. Plans and specifications for a project and local building requirements must be followed@ even if they differ from the information in this booklet.
