When CSA certifies a precast manufacturing facility to the A23.4 standard, a CSA
engineer visits the facility and conducts an onsite review and approval of the facility’s
quality system and actual production procedures. This review includes (but is not limited
to),
- Reviewing the factory’s Quality manual and work instructions;
- observing actual work processes to ensure the procedures in the quality manual are
properly implemented;
- reviewing material data sheets, mill certificates and material test records;
- reviewing equipment calibrations;
- reviewing shop drawings;
- witnessing fabrication of reinforcement cages and placement of hardware;
- witnessing concrete batching, placement, finishing, and curing;
- witnessing pre-pour and post-pour inspections conducted by the factory;
- verifying that the products are being manufactured as detailed on shop drawings;
- witnessing concrete testing and reviewing test data; and
- witnessing stripping, handling, storage and transportation operations.
Once the manufacturing facility has been certified, a CSA engineer visits the facility
regularly to conduct follow up audits to verify ongoing compliance to the CSA A23.4
standard.
CSA has the A257 standard for circular manholes, however, we do not offer a
certification program to this standard at this time.
