The NRMCA Research, Engineering and Standards Committee has released a spreadsheet and guidance document with which producers can calculate the financial impact caused by deficiencies in raw materials, plant equipment and production.
“Cost of Poor Quality” (COPQ) measures a producer’s total cost of internal and external failures leading to ready mixed concrete not meeting specifications or rejected prior to placement.
COPQ can be reduced by designing, implementing, and maintaining a quality management system. More specifically, the company can improve quality practices by:
1. Hiring competent technical staff and training them
2. Testing ingredient materials and production concrete periodically
3. Conducting data analysis and corrective action
4. Educating contractors, A/Es, test labs, suppliers on best practices for concrete quality
5. Inspecting and auditing plants and personnel
6. Ensuring batching accuracy is within ASTM C94 tolerances particularly for water and cement
7. Ensuring good quality practices at the plants such as stockpile management, aggregate moisture probe calibration, dispenser accuracy and maintenance, daily plant check etc.
