PCI-CERTIFIED PLANTS DIRECTORY Visit pci.org for the most up-to-date listing of PCI-Certifi ed Plants. AS OF OCTOBER 2021 When it comes to quality, why take chances? When you need precast or precast, prestressed concrete products, choose a PCI-Certifi ed Plant. You’ll get confi rmed capability—a proven plant with a quality assurance program you can count on. Whatever your needs, working with a plant that is PCI-certifi ed in the product groups it produces will benefi t you and your project. • You’ll fi nd easier identifi cation of plants prepared to fulfi ll special needs. • You’ll deal with established producers— many certifi ed for more than 30 years. • Using quality products, construction crews can get the job done right the fi rst time, keeping labor costs down. • Quality products help construction proceed smoothly, expediting project completion. GROUPS > GROUP A – ARCHITECTURAL PRODUCTS CATEGORY AT – ARCHITECTURAL TRIM UNITS Wet-cast, nonprestressed products with a high standard of fi nish quality and of relatively small size that can be installed with equipment of limited capacity such as sills, lintels, coping, cornices, quoins, medallions, bollards, benches, planters, and pavers. CATEGORY AD – ARCHITECTURAL PRECAST PRODUCTS Includes structural products with an architectural fi nish such as plant applied fi nishes, formliners, brick veneers or extruded profi les. CATEGORY AC – ARCHITECTURAL PRECAST PRODUCTS Includes primarily cladding or non-load bearing products with architectural fi nishes such as plant applied fi nishes, formliners, brick veneers or extruded profi les, as well as products in Categories AT and AD. CATEGORY AB – ARCHITECTURAL PRECAST PRODUCTS Includes primarily cladding or non-load bearing products with multiple concrete mixes and textures, a variety of three-dimensional projections, radius mold surfaces, or sequential returns, as well as products in Categories AT, AD, and AC. CATEGORY AA – ARCHITECTURAL PRECAST PRODUCTS Guide Specifi cation To be sure that you are getting the full benefi t of the PCI Plant Certifi cation Program, use the following guide spec ifi cation for your next project: “ Manufacturer Qualifi cation: The precast con-crete man ufacturing plant shall be certifi ed by the Precast/Pre stres sed Concrete In stitute Plant Certifi -cation Program. Man ufacturer shall be certifi ed at time of bidding. Certifi cation shall be in thefollowing product group(s) and category(ies): [Select appropri-ate groups and categor ies (AT or A1), (B1,2,3, or 4), (C1,2,3, or 4), (G)]. ” Includes primarily cladding or non-load bearing products with multiple concrete mixes and textures, a variety of three-dimensional projections, radius mold surfaces, sequential returns, and most stringent product and installation tolerances, as well as products in Categories AT, AD, AC and AB. > GROUP B – BRIDGES Please note for Group B, Category B1: Some precast concrete products such as highway median barriers, box culverts, and three-sided arches are not automatically included in routine plant audits. They may be included at the request of the precast concrete producer or if required by the project specifi cations. CATEGORY B1 – PRECAST CONCRETE BRIDGE PRODUCTS Mild-steel-reinforced precast concrete elements that include some types of bridge beams or slabs, sheet piling, pile caps, retaining-wall elements, parapet walls, sound barriers, and box culverts. CATEGORY B2 – PRESTRESSED MISCELLANEOUS BRIDGE PRODUCTS Product Groups and Categories The PCI Plant Certifi cation Program is focused around four groups of products, designated A, B, C, and G. Products in Group A are audited to the standards in MNL–117 . Products in Groups B and C are audited to the standards in MNL–116. Products in Group G are audited according to the standards in MNL–130. The standards referenced above are found in the following manuals: • MNL–116 Manual for Quality Control for Plants and Production of Structural Precast Concrete Products • MNL–117 Manual for Quality Control for Plants and Production of Architectural Precast Concrete Products • MNL–130 Manual for Quality Control for Plants and Production of Glass Fiber Reinforced Concrete Products Within Groups A, B, and C are categories that identify product types and the product capability of the individual plant. The categories refl ect similarities in the ways in which the products are produced. In addition, categories in Groups A, B, and C are listed in ascending order. In other words, a plant certifi ed to produce pro ducts in Category C4 is automat ically certifi ed for products in the preceding Categories C1, C2, and C3. A plant cer tifi ed to produce products in Category B2 is automatically qualifi ed for Cat egory B1 but not Categories B3 or B4. Any precast, prestressed element excluding super-structure beams. Includes piling, sheet piling, retaining wall elements, stay-in-place bridge deck panels, and products in Category B1. CATEGORY B3 – PRESTRESSED STRAIGHT-STRAND BRIDGE MEMBERS Includes all superstructure elements such as box beams, I-beams, bulb tees, stemmed members, solid slabs, full-depth bridge deck slabs, and products in Categories B1 and B2. CATEGORY B4 – PRESTRESSED DEFLECTED-STRAND BRIDGE MEMBERS Includes all products covered in Categories B1, B2, and B3. > GROUP C – COMMERCIAL (STRUCTURAL) CATEGORY C1 – PRECAST CONCRETE PRODUCTS Mild-steel-reinforced precast concrete elements including sheet piling, pile caps, piling, retaining wall elements, fl oor and roof slabs, joists, stairs, seating members, columns, beams, walls, spandrels, etc. CATEGORY C2 – PRESTRESSED HOLLOW-CORE AND REPETITIVE PRODUCTS Standard shapes made in a repetitive process prestressed with straight strands. Included are hollowcore slabs, railroad ties, fl at slabs, poles, wall panels, and products in Category C1. CATEGORY C3 – PRESTRESSED STRAIGHT-STRAND STRUCTURAL MEMBERS Includes stemmed members, beams, columns, joists, seating members, and products in Categories C1 and C2. CATEGORY C4 – PRESTRESSED DEFLECTED-STRAND STRUCTURAL MEMBERS Includes stemmed members, beams, joists, and products in Categories C1, C2, and C3. > GROUP G – GLASS-FIBER-REINFORCED CONCRETE (GFRC) These products are reinforced with glass fi bers that are randomly dispersed through-out the product and are made by spraying a cement/sand slurry onto molds. This produces thin-walled, lightweight cladding panels.
