Since its founding in 1954, the Precast/Prestressed Concrete Institute (PCI) has developed, maintained, and disseminated industry standards for the precast/prestressed concrete structures industry. Many of these standards, which are used by PCI, its members, and the design community, have been in place for over 50 years.
PCI has a full-time, licensed, professional engineering staff that provides administrative oversight and support to help manage and keep records of the standards activities. For more information about the procedures for developing, approving, and maintaining PCI standards, please refer to Procedures for the Development, Approval, and Maintenance of Precast/Prestressed Concrete Institute Standards.
In March 2014, PCI was accredited by the American National Standards Institute (ANSI) as an accredited ANSI Standards Developer. With this accreditation, PCI's voluntary consensus standards relative to the design, detailing, fabrication, transportation, and erection of precast and prestressed concrete are formally recognized.
With this accreditation, PCI is also able to broaden and strengthen already existing PCI standards and subject them to a thorough review and evaluation by the PCI Standards Committee as they go through the process of becoming ANSI Standards. Once approved, these standards will be recognized by ANSI as guiding national standards for the precast/prestressed concrete structures industry. View the ANSI essential requirements.
How You Can Participate
PCI continues to broaden the membership base of its American National Standards consensus body and seeks new members in all membership categories to participate in the creation of new standards in quality control, fire resistance design, tolerances, glass-fiber-reinforced concrete (GFRC), and other important topics. In particular, we wish to expand membership from the producer, user, and general interest communities.
Individuals seeking membership on the Standards Committee shall submit a written request to PCI indicating their interest in the work of the Standards Committee and their qualifications, willingness to participate, and affiliations that might affect their classification. Applicants shall identify their interest category. Membership on the PCI Standards Committee is open to all directly and indirectly affected parties subject to the selection procedure set forth in PCI's operating procedures. Please submit all written requests of interest to standards@pci.org
Proposed PCI Standards for Public Comment
Responses to Public Comments and Second Public Review Period
Specification for Precast Concrete Tolerances (PCI 135)
A
draft of
Specification for Tolerances of Precast Concrete, PCI 135 was submitted for public review and comment from March 10, through April 25, 2024. Public comments were received, and comments have been responded to in accordance with the Procedures for Development, Approval, and Maintenance of PCI standards.

Design Standard Committee Call for Members
The PCI Design Standard committee is accepting applications for membership for a six-year cycle that ends in 2031. The committee shall consist of not more than 20 voting members: a chair, four to six representatives of producer Members, four to eight professional members, one to two associate members, and three to five academic members.
Your application submission signifies your request to serve for a six-year cycle within the context of the committee’s Mission:
The committee will identify topics to be codified for precast concrete. The committee will oversee the development of design standards at the technical committee level and, where appropriate, will develop design standard provisions. The committee will recommend to the Research and Development (R & D) Council research topics that will assist PCI with the acceptance and adoption of standards by model codes for existing or new precast concrete design methods. Objectives include the following:
-
To aid designers of precast concrete and provide standards for the design, construction, and modification of precast members and structures
- To provide up-to-date and accurate information to specifiers and designers
- To develop design standards by the ANSI-approved consensus process to be integrated into the structural precast concrete standard ACI-PCI 319 to be referenced by the International Building Code.
- To provide educational information to assist members in writing standards language.
Submit your application to standards@pci.org. Membership is by invitation-only.
