When you need precast or precast, prestressed concrete products, choose a PCI-Certified Plant. You’ll get confirmed capability—a proven plant with a quality assurance program you can count on.

Whatever your needs, working with a plant that is PCI-certified in the product groups it produces will benefit you and your project.

• You’ll find easier identification of plants prepared to fulfill special needs.

• You’ll deal with established producers—many certified for more than 30 years.

• Using quality products, construction crews can get the job done right the first time, keeping labor costs down.

• Quality products help construction proceed smoothly, expediting project completion.

To be sure that you are getting the full benefit of the PCI Plant Certification Program, use the following guide specification for your next project:

“Manufacturer Qualification: The precast concrete manufacturing plant shall be certified by the Precast/Prestressed Concrete Institute Plant Certification Program. Manufacturer shall be certified at time of bidding. Certification shall be in the following product group(s) and category(ies): [Select appropriate groups and categories (AA, AB, AC, AD, or AT), (B1,2,3, or 4), (C1,2,3, or 4), (G)].”

The PCI Plant Certification 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–116Manual for Quality Control for Plants and Production of Structural Precast Concrete Products

• MNL–117Manual for Quality Control for Plants and Production of Architectural Precast Concrete Products

• MNL–130Manual 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 reflect similarities in the ways in which the products are produced. The A categories are in descending order (AB is certified for AB, AC and AD whereas AD is only certified for AD). Yet, B4 is certified in all B categories and B1 is only certified in B1. So, B1 is the ‘basic level’ and AD is the ‘basic level.’ Going for AA to AD would be descending levels of complexity and B1 to B4 would be ascending levels of capability.

Wet-cast, nonprestressed products with a high standard of finish 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.

Includes structural products with an architectural finish such as plant applied finishes, formliners, brick veneers or extruded profiles.

Includes primarily cladding or non-load bearing products with architectural finishes such as plant applied finishes, formliners, brick veneers or extruded profiles, as well as products in Categories AT and AD.

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.

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.

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 specifications.

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.

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.

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.

Mild-steel-reinforced precast concrete elements including sheet piling, pile caps, piling, retaining wall elements, floor and roof slabs, joists, stairs, seating members, columns, beams, walls, spandrels, etc.

Standard shapes made in a repetitive process prestressed with straight strands. Included are hollowcore slabs, railroad ties, flat slabs, poles, wall panels, and products in Category C1.

Includes stemmed members, beams, columns, joists, seating members, and products in Categories C1 and C2.

Includes stemmed members, beams, joists, and products in Categories C1, C2, and C3.

These products are reinforced with glass fibers 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.

When you need precast or precast, prestressed concrete products, choose a PCI-Certified Erector. You’ll get confirmed capability with a quality assurance program you can count on.

Whatever your needs, working with an erector who is PCI-certified in the structure categories listed will benefit you and your project.

• You’ll find easier identification of erectors prepared to fulfill special needs.

• Using a PCI-Certified Erector is the first step toward getting the job done right the first time, thus keeping labor costs down.

• PCI-Certified Erectors help construction proceed smoothly, expediting project completion.

To be sure that you are getting an erector from the PCI Field Certification Program, use the following guide specification for your next project:

“Erector Qualification: The precast concrete erector shall be fully certified by the Precast/Prestressed Concrete Institute (PCI) prior to the beginning of any work at the jobsite. The precast concrete erector shall be certified in Structure Category(ies): [Select appropriate groups and categories S1 or S2 and/or A1].”

The PCI Field Certification Program is focused around three erector classifications. The standards referenced are found in the following manuals:

• MNL–127Erector’s Manual - Standards and Guidelines for the Erection of Precast Concrete Products

This category includes horizontal decking members (e.g. hollow-core slabs on masonry walls), bridge beams placed on cast-in-place abutments or piers, and single-lift wall panels.

This category includes everything outlined in Category S1 as well as total–precast, multi- product structures (vertical and horizontal members combined) and single- or multistory load-bearing members (including those with architectural finishes).

This category includes non-load-bearing cladding and GFRC products, which may be attached to a supporting structure.
