“The initial cost of plant certification is minimal when compared to the benefits of focusing on quality control in the plant. We can document savings in raw materials and purchased items, fewer damaged or rejected castings, and reduced labor and rework of products on the job site. This precast certification program corrects plant errors before they become high-cost problems.”

Program Highlights
As a powerful business improvement tool, the NPCA Plant Certification program provides the framework and guidance you need to consistently meet customer expectations and regulatory quality requirements.
- Plants are evaluated on product quality, documentation, production procedures, management, personnel training and equipment.
- NPCA certifies the processes involved in the manufacture of all precast concrete products, including product-specific requirements such as stormwater concrete pipe, sanitary concrete pipe, round manholes, box culverts, septic tanks and grease interceptors.
- Certified plants are required to:
- Maintain strict adherence to the best practices set forth in the NPCA Quality Control Manual for Precast Concrete Plants.
- Pass critical sections of the NPCA Quality Control Manual for Precast Concrete Plants that include fabrication of reinforcing steel, positioning of reinforcing steel and concrete testing.
- Maintain and follow a plant-specific, comprehensive quality control manual and designated standards, maintain solid management practices, keep accurate records, follow standard production procedures and employ trained and qualified personnel.
- The NPCA Plant Certification includes unannounced inspections by third-party consulting engineers, which are conducted by Hanson Professional Services and RBA Audit LLC (both accredited to ISO/IEC 17020: General criteria for the operation of various types of bodies performing inspection).
