The “Structural Precast Concrete—Code Requirements and Commentary” (“Code”) provides minimum requirements for the materials, design, and detailing of structural precast concrete buildings and, where applicable, nonbuilding structures. This Code was developed using a consensus process and addresses plant-produced and site-produced structural precast concrete that contains nonprestressed reinforcement or pretensioned reinforcement, or both. The Design Standard Committee of Precast/Prestressed Concrete Institute was instrumental in the development of code provisions and commentary for this Code and whose efforts are gratefully acknowledged. 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.
This Code adheres to the chapter and section numbering of ACI CODE-318-25 and either cites or repeats applicable provisions from ACI CODE-318. Provisions that are identical to ACI CODE-318 and are repeated in this Code are denoted with an equal sign (“=”). Provisions that are applicable to precast concrete but are not repeated in the Code are denoted as “See ACI CODE-318.” Design and detailing requirements for structural systems or for individual members are presented in chapters devoted to those individual subjects, and the chapters are arranged in a manner that generally follows the process and chronology of design and construction. Information and procedures that are common to the design of multiple member types are located in utility chapters. Within chapters, the terms “out of scope” and “not applicable” are used for numbered section headings from ACI CODE-318 that are not covered by this Code, while the term “intentionally left blank” is used as a place holder to maintain consistency with section numbering in situations where ACI CODE-318 includes a numbered provision that is not also in this Code.
Uses of the Code include adoption by reference in a general building code, and it is 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 considerations of the committee in developing the Code are discussed in the Commentary, with emphasis given to the explanation of provisions. Given the similarity in design requirements for structural concrete that is either cast-in-place or precast, the commentary explains the difference in application. The commentary also provides explanations regarding situations where use of both ACI CODE-318 and this Code is necessary. For instance, design of cast-in-place, nonprestressed concrete members or structures requires the use of ACI CODE-318 alone. Design of precast concrete structures requires the use of this Code and ACI CODE-318. Design of precast, post-tensioned concrete structures requires the use of applicable provisions of ACI CODE-318, ACI/PCI CODE-319, and ACI/PTI CODE-320. For provisions that specifically address post-tensioning and are generally not within the scope of precast concrete, this code references either ACI CODE-318 or ACI/PTI CODE-320, as applicable.
Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail. Other documents that provide suggestions for carrying out the requirements of the Code are also cited, including PCI Standards and PCI or Tilt-up Concrete Association (TCA) design manuals, recommended practices, and reports.

This is a Reference Specification that the Architect/Engineer can apply to any construction repair and rehabilitation project involving structural concrete by citing it in the Project Specifications. Mandatory requirements and optional requirements checklists are provided to assist the Architect/Engineer in supplementing the provisions of this Specification, as required or needed, by designating or specifying individual project requirements. The first section covers general construction requirements for repair Work. The second section covers shoring and bracing of the structure or member to be repaired, and addresses sequencing of repair Work as the structure is unloaded and reloaded. The third section covers concrete removal and preparation of the concrete substrate for repair and defines common equipment and methods. The next five sections cover materials and proportioning of concrete; proprietary cementitious and polymer repair materials; reinforcement; production, placing, finishing, and curing of repair materials; formwork performance criteria and construction; treatment of joints; embedded items; repair of surface defects; mockups, and finishing of formed and unformed surfaces. New sections included in this edition of the Specification includes waterproofing cracks by chemical grout injection, architectural concrete repair, structural precast concrete repair, unbonded post-tensioned concrete repair, overlays, protective membranes, and cathodic protection by galvanic anodes. Provisions governing testing, evaluation, and acceptance of repair materials as well as acceptance of the repair Work are included. Sections 16, 17 and 18 incorporate by reference other ACI specifications into this ACI Standard: ACI SPEC-503.7 for crack repair by epoxy injection, ACI SPEC-506.2 for shotcrete, and ACI SPEC-440.12 for wet-layup FRP.

Serviceability is considered a critical factor in the management of concrete bridges and structures. Typical components for evaluating the serviceability limit state include cracking, deflection, and vibration. Additionally, to ensure the adequate performance of load-bearing members, proper evaluation methodologies should be adopted. Although numerous research projects have been undertaken to examine the serviceability and performance assessment of concrete bridges and structures, significant endeavors are still required to address unexplored challenges. Of interest are the development of simplified prediction and appraisal approaches; novel techniques for quantifying stress levels; serviceability criteria under unusual distress; and the characterization of structural responses when exposed to blast, wind, and seismic loadings. This Special Publication contains 11 papers selected from technical sessions held in the ACI Fall Convention in November 2024. The Editors wish to thank all contributing authors and anonymous reviewers for their rigorous efforts. The Editors also gratefully acknowledge Ms. Barbara Coleman at ACI for her knowledgeable guidance. Yail J. Kim, University of Colorado Denver, Editor Hyeon-Jong Hwang, Konkuk University, Editor

This Design Specification provides minimum requirements for performing a service life evaluation as part of the design process for new structures and implementing the results of the evaluation into the construction phase. This Design Specification can be used as part of a design-bid-build project, a design-build project, or other project delivery options. The Design Specification is independent of the specific model or technique used to perform the service life evaluation. Although service life modeling is commonly used to evaluate chloride transport causing corrosion deterioration, the approach outlined in this Design Specification can be used for any deterioration mechanism that is capable of being modeled. The service life engineer performing the evaluation can either be the prime consultant or a subconsultant. A service life report is produced as part of this specification, documenting the service life evaluation, followed by a service life record report documenting the implementation into the new construction.
Keywords:
degradation mechanisms; deterministic modeling; durability; performance design; probabilistic modeling; quality control/quality assurance; service life prediction.
