The Precast/Prestressed Concrete Institute (PCI) is the technical institute for the precast concrete structures industry. PCI develops, maintains, and disseminates the Body of Knowledge (BOK) necessary for designing, fabricating, and constructing precast concrete structures. The BOK refers to the collective knowledge of an industry that is relied upon to design and build with a specific material or system. It is from this BOK that building codes, design guides, education programs, certification, and more are derived.
Founded in 1954 by the engineers and firms that pioneered prestressed concrete technology in the United States. PCI offers a vast selection of resources including design guides and manuals, guide specifications, a peer-reviewed technical journal, and more.
