Subject: CSA Certification to CSA A23.4 Standard for Precast Concrete, Materials
and Construction.
Dear Mr. Friesen:
This letter is to confirm that Diamond Precast Concrete Ltd. is certified to the CSA
A23.4 standard for precast concrete.
The CSA certification program is a quality based program, where CSA reviews and
approves the manufacturing facility’s quality control system and actual work procedures
conducted in the facility and confirms that the facility complies with A23.4 requirements.
Part of this review includes verifying that the products being constructed in the
manufacturing facility are manufactured in compliance with the shop drawings for that
product.
The CSA certification program requires every manufacturing facility to have a full time or
retained licensed professional engineer to verify that products meet the CSA A23.4 and
CSA certification requirements on a continuing basis and issue a statement of
compliance(s). The engineering and design of the product is left to a licensed
professional engineer.
CSA A23.4 standard contains compliance requirements for (but is not limited to),
- materials used in the construction of the product;
- forms, including preparation;
- reinforcement and hardware placement;
- concrete casting, placing, finishing, and curing;
- pre-pour and post-pour inspections during the construction phase;
- concrete testing;
- stripping, handing, storage, and transportation of the finished products; and
- product markings.
