NRMCA Revises Plant Certification Check List

Popular Tool to Certify Ready Mixed Concrete Plants

SILVER SPRING, MD -- The National Ready Mixed Concrete Association has released the 11th revision to the QC3 Plant Certification Check List that is used nationwide to certify ready mixed concrete production facilities. Revisions have been developed and approved by the NRMCA Research Engineering and Standards Committee and further approved by the NRMCA Board of Directors. The revised check list will be provided to inspecting engineers approved to perform inspections for the NRMCA certification program. Revisions to the plant inspection program are made when referenced standards are revised, to address new technology and to clarify intent from feedback by inspectors.

Along with this revision, significant updates and revisions have been made to the NRMCA Plant Inspector's Guide. The Guide describes in more detail the intent of each item in the check list with images and numerical examples when appropriate. The Guide is used as the basis for approving inspectors and their assistants to perform inspections for the NRMCA program. The approved inspectors are required to obtain the current copy of the Guide and to update their contact information to remain on the approved list. The revised check list will be effective for new requests for certification starting May 15 with a one-month transition period.

This latest revision of one of NRMCA's most popular and important certification programs has its roots in the early 1960's when failures of concrete were hurting its reputation as a building material. NRMCA's certification program is one of the only means to ensure that concrete production facilities conform to industry standards, such as ASTM C94/C94M, Specification for Ready Mixed Concrete. NRMCA's Plant Certification Program has evolved over the ensuing decades and has seen greater acceptance by concrete producers and specifying agencies. Approximately 2,300 plants and 18,000 delivery vehicles are currently certified by the NRMCA program. Certified plants and approved inspecting engineers are posted on NRMCA's Web site.
