About Us


Our Story

Since being founded in 1991, CNCA has built a reputation as a trusted technical resource. Our team has evolved into a sought-after resource for our expertise on a wide range of topics related to materials, design, and construction, for private and public entities. Our association has also gained recognition for being collaborative. This has been pivotal in developing codes, standards, policies, and legislation that requires broad stakeholder engagement. Our goal is to build on these core strengths to take on new challenges and opportunities. We’re ready to shape the future with you.
