The Engineering Division and other NRMCA staff represent the ready mixed concrete industry on committees and organizations that set standards impacting the industry. The RES Committee is consulted and provides direction on initiatives and positions for the industry. Participation includes committees of the American Concrete Institute, ASTM International, Transportation Research Board, and technical committees of allied industry groups. NRMCA Staff also participate as industry representatives on panels and committees of the Federal Highway Administration and other specifying entities as requested.

The technical advocacy initiatives of NRMCA support its activities in promotion, research, education and government advocacy. Participation in the industry standards area ensures that NRMCA provides current information to its members and customers of the industry. It ensures that NRMCA can provide its members with a solution to a wide range of issues either with supporting information, or by directing them to an expert who will know.

When requested, NRMCA has provided comments on master specifications of engineering design firms and advised on requirements for concrete in concrete specifications to its members. NRMCA engineers Lionel Lemay, Karthik Obla and Colin Lobo are licensed engineers. Click here for their contact information.

Some committees with representation by NRMCA personnel include the
American Concrete Institute and ASTM International.
