C.3.3 Group BA
Group BA products are produced with the additional requirements for architectural finishes. Group BA is
divided into the same four categories as Group B and are designated Categories BA1, BA2, BA3, and BA4.
The category descriptions are identical with the category descriptions for Group B except that the
manufacturer shall have the capability to apply architectural finishes in accordance with the provisions of
this Standard. Each BA category includes the preceding BA categories and supersedes the equivalent
Group B category.
C.4 Group C (commercial [structural] products) and Group
CA (commercial [structural] products with architectural
finishes)
C.4.1 General
Groups C and CA include structural and non-structural elements of buildings and other structures,
excluding bridges. These products shall be produced in accordance with the requirements of this
Standard.
C.4.2 Group C
Group C is divided into four categories:
(a) Precast concrete products (C1) are conventionally reinforced precast concrete elements, including
piling, sheet piling, pile caps, retaining wall elements, slabs, joists, stairs, seating members, columns,
spandrels, beams, walls, or other similar products.
(b) Prestressed hollow core and repetitive products (C2) are precast concrete products with standard
shapes that are generally produced by a repetitive process that may be mechanized and pretensioned
or post-tensioned with straight strands. Examples are hollow core slabs, railroad ties and piling. This
category includes Category C1.
(c) Prestressed straight-strand structural members (C3) are precast concrete structural members
pretensioned or post-tensioned with straight strand, including stemmed members, beams, columns,
joists, and segmental components. This category includes Categories C1 and C2.
(d) Prestressed deflected-strand structural members include the same class of products as Category C3
and which are pretensioned or post-tensioned with deflected strands. This category includes
Categories C1, C2, and C3.
C.4.3 Group CA
Group CA products are produced with the additional requirements for architectural finishes. Group CA is
divided into the same four categories as Group C and are designated Categories CA1, CA2, CA3, and CA4.
The category descriptions are identical with the category description in Group C, except that the
manufacturer will have demonstrated the capability to apply architectural finishes in accordance with the
provisions of this Standard. Each CA category includes the preceding CA categories and supersedes the
equivalent Group C category.
C.5 Group S (standard products)
Group S includes plain or reinforced concrete elements, without architectural finishes, not included in
Groups A, B, BA, C, or CA that are required to be manufactured in accordance with the provisions of this
Standard. Products in Group S are often manufactured for a particular application in custom built forms
on-demand or kept in inventory.
