COVERAGE:

Prequalification program for precast concrete
manufacturers: to assess and evaluate the capabilities of precast concrete
manufacturing plants to fabricate precast concrete products and elements to the
requirements of CSA A23.4 Standard. CSA prequalification program classifies
precast concrete products, fabricated in a prequalified plant, under one or more
of the precast concrete product group classification categories and
subcategories outlined in CSA A23.4 Standard.

PRECAST CONCRETE PRODUCT GROUP CLASSIFICATIONS

Precast concrete products are classified into the
following categories and subcategories:

Group A (Architectural Products)

AT ? Architectural trim units
A1 ? Architectural cladding and load bearing
units

Group B (Bridge Products); and Group BA (Bridge
Products with Architectural Finishes)

B1 ? Precast concrete bridge products
B2 ? Prestressed miscellaneous bridge products
B3 ? Prestressed straight-strand bridge members
B4 ? Prestressed deflected-strand Bridge Members
BA1, BA2, BA3, BA4 – Bridge products with an architectural finish

Group C (Commercial Structural Products); and
Group CA (Commercial Structural Products with Architectural Finishes)

C1 ? Precast concrete products
C2 ? Prestressed hollow core and repetitive
products
C3 ? Prestressed straight-strand structural members
C4 ? Prestressed deflected-strand structural members
CA1, CA2, CA3, CA4 – Commercial products with an architectural
finish

Group D (Drainage Products)

D1 ? Standard precast concrete drainage
products

Group S (Standard Products without an
Architectural Finish)

NOTES:

• Manufacturers may be prequalified in up to five of the product group
  classifications.
• Prequalified plants are normally permanent facilities, but the
  procedures also permit assessment of temporary or on-site operations.
• CSA inspection/audit format for this prequalification program
  utilizes a grading system, where a minimum passing grade is established
  for each applicable division or clause (such as facility/personnel,
  engineering, material, concrete production, quality control,
  handling/storage, etc.) and applying a percentage weight to the given
  grades. An overall plant score will be determined by compiling the score
  for each applicable division or clause with the percentage weight
  stated.
• To obtain and maintain CSA prequalification under this program, a
  manufacturer shall receive a minimum overall plant score of 80% on their
  audits/inspections and a minimum passing grade of 70% on each applicable
  division or clause.
• Precast concrete elements manufactured in accordance with the
  requirements of CSA A23.4 standard, by manufacturers who are
  prequalified under this program, are considered certified and eligible
  to bear the CSA certification mark.

REQUIREMENTS:

CSA-A23.4

Precast Concrete – Materials and Construction

The above Standard may also require the use of
associated Informs, Notices and/or Supplements due, for example, to new
requirements becoming effective after publication of the Standard.

MANUFACTURING PLANT PREQUALIFICATION

Manufacturers who comply with the requirements of this
CSA Prequalification Program will be presented with a Certificate of
Qualification from CSA to indicate that the manufacturer has met CSA program
requirements and implemented a documented quality control system, as required by
this program, for the manufacturing processes involved in the manufacturing of
precast concrete elements in the categories and subcategories for which they are
prequalified.

Certificates of Qualification are not transferrable,
either by personnel or plant, and remain in the ownership of CSA Group, and
shall be returned to CSA at any time upon written request by CSA. Certificates
of Qualification are valid for 2 years from the date of issue; a Certificate of
Qualification shall remain in effect for the 2 years expiry period unless its
return has been requested in writing by CSA.

PRODUCT MARKING:

Individual pre-cast concrete elements shall be marked
with the following information, in a permanent manner, either on the product or
on a tag attached to the product, or on the documentation accompanying the
product (provided the latter is cross-referenced with the documentation), or by
any other means acceptable to CSA:

1. manufacturer's name, trade name, trademark, or CSA file number;
2. identification, as shown on the shop drawings;
3. date of casting; and
4. CSA Mark or the letters "CSA".

Note: Certain jurisdictions in Canada
require the use of French language in markings; it is the responsibility of
the manufacturer to determine where this is required.
