The new Third Edition of the Steel Deck Institute Manual of Construction with Steel Deck (MOC3) continues the tradition established by earlier editions to provide information necessary for the proper field usage of steel deck. This edition is reformatted for easier use with updated references, including those for the SDI QA/QC Standard for Quality Control and Quality Assurance of Steel Deck.

This instructional manual has been prepared by the Post-Tensioning Institute's Committee for Training and Certification of Field Personnel for Unbonded Post-Tensioning soley as a recommended general guide and assistance to the placement, installation and inspection of unbonded single strand post-tensioning systems, the operation of stressing equipment, and accessories.

This manual is intended to provide standards (shown in boldface) and corresponding guidelines (commentary) for the erection of plant-produced precast and prestressed concrete products, and to establish a level of quality that will be recognized and respected by the construction industry.

The digest includes descriptions of the standard products: K-Series joists, LH/DLH-Series joists, Joist Girders and now CJ-Series joists, how joist products are prepared, tagged, loaded and shipped from the joist manufacturers plant, how they are to be unloaded and stored at the job site, how the joist products are to be erected including bridging, and field inspection. Other topics covered in the digest are panelized erection and common field issues.

This edition contains information related to the newest standard joist product, the CJ-Series joists that were introduced in 2007. It also includes updated information on Bridging in Chapter 8 as well as some additional topics added to the list of Miscellaneous Topics - Common Field Issues in Chapter 9.

General contractors, steel erectors, inspectors, and building officials would most benefit from this Technical Digest. Engineers and Architects would also benefit from the information contained in the digest if part of their responsibilities is to oversee joist and Joist Girder projects under construction.

Carpentry & Building Construction is a comprehensive carpentry program that focuses on residential construction with many procedures also applying to light commercial construction.

The Code covers the design and construction of masonry structures, with subjects covered ranging from quality assurance to the details and development of reinforcement. Compliance with the Specification is required by the Code to control materials, labor and construction.

The “Building Code Requirements for Structural Concrete” (“Code”) provides minimum requirements for the materials, design, and detailing of structural concrete buildings and, where applicable, nonbuilding structures. This Code addresses structural systems, members, and connections, including cast-in-place, precast, plain, nonprestressed, prestressed, and composite construction. Among the subjects covered are: design and construction for strength, serviceability, and durability; load combinations, load factors, and strength reduction factors; structural analysis methods; deflection limits; mechanical and adhesive anchoring to concrete; development and splicing of reinforcement; construction document information; field inspection and testing; and methods to evaluate the strength of existing structures. “Building Code Requirements for Concrete Thin Shells” (ACI 318.2) is adopted by reference in this Code.The Code user will find that ACI 318-14 has been substantially reorganized and reformatted from previous editions. The principal objectives of this reorganization are to present all design and detailing requirements for structural systems or for individual members in chapters devoted to those individual subjects, and to arrange the chapters in a manner that generally follows the process and chronology of design and construction. Information and procedures that are common to the design of members are located in utility chapters.

The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate American Welding Society (AWS) standard. Uses of the Code include adoption by reference in a general building code, and earlier editions have been widely used in this manner. The Code is written in a format that allows such reference without change to its language. Therefore, background details or suggestions for carrying out the requirements or intent of the Code provisions cannot be included within the Code itself. The Commentary is provided for this purpose. Some of the considerations of the committee in developing the Code are discussed within the Commentary, with emphasis given to the explanation of new or revised provisions. Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail.
