Earning a Diamond Commendation demonstrates that your company follows best practices proven to improve quality, safety, and excellence.
The self-assessment process helps companies benchmark their operations against a national standard, identify areas for improvement, and earn national recognition for their commitment to quality.
Taken together, these five commendations provide a blueprint for excellence in all aspects of the industry’s operations.

Diamond Quality
Focuses on the quality of the material produced. Areas evaluated include quality management, RAP and aggregate handling, asphalt storage, drying and mixing, air quality, truck scales, silos, and control rooms.

Diamond Paving
Designed for paving crews. Areas evaluated include training of supervisors and crew members, use of best practices in paving, and compliance.

Diamond Achievement
Covers operations in the manufacturing plant and around the plant site: appearance, operations, environmental practices, safety, permitting and regulatory compliance, and community relations. An optional level assesses the facility’s social, economic, and environmental efforts to gauge how well it puts the principles of sustainability and community engagement into action.

Diamond Terminal
Covers operations in and around the terminal facility site. Aspects addressed include appearance, operations, environmental practices, safety, permitting and regulatory compliance, and community relations.
