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
