City of Houston Certificate of Approval


Quasar / CSA-A660 Certificate


The CAN/CSA A660 Standard was developed to help officials in reviewing building permit applications for projects that use pre-engineered steel buildings, and to ensure that buyers receive a quality product.


As part of the CAN/CSA A660 compliance, manufacturers are required to provide a “Certificate of Design and Manufacturing Conformance” signed and sealed by a licensed Professional Engineer for each building project.

CAN/CSA A660 certification includes a quality control audit like ISO, however, ISO certification only verifies that a company can manufacture a product consistently and does not address whether a steel building system has been designed in accordance with the applicable codes or whether the staff is qualified to undertake the work. CAN/CSA A660 audits include all aspects of the manufacturer’s process, including engineering design methods and personnel, materials control, fabrication, warehousing, packaging, shipping, erecting, and quality assurance in the plant.
