Who We Are…
The SLC3 is the region’s leading all-inclusive construction industry association, uniting owners and providers of services and products that shape the natural and built environment.
We’re the largest Local User’s Council in the United States—led by owner (project owners) members and supported by associate members (providers). Our work is anchored in four key pillars that drive industry impact:
- Innovation – Advancing project delivery, safety, and technology to elevate performance across design and construction.
- Education – Our key offering is critical continuing education for engineers, architects, and safety professionals while developing stronger leaders at every level. But, we offer continuing education for all staff! We offer leadership, sales and marketing, and life skills training.
- Equity Empowerment – Promoting diversity, inclusion, and ultimately equity across the industry by ensuring all voices are heard and valued, and uniting with each other.
- Collaboration – Fostering a united, inclusive community where every member has a seat at the table—and together, we build a stronger industry and region. And yes, we also host notable networking events! Just ask around!
Our Mission
Building a better future by uniting the greater St. Louis region’s design and construction community in achieving innovation, offering advanced education, equity empowerment, and fostering collaboration among all stakeholders.
SLC3 Membership
The membership of the SLC3 includes some of the largest construction consumers in the greater St. Louis region. Because of the size and volume of their construction activities, the Council is recognized as the voice of “Owners” in the region. Thus, our voice and impact on construction industry practices is strong and influential. However, we are a community of all stakeholders! We welcome anyone doing business in the natural and built environment. We are truly the ONLY association offering membership bringing together the AEC community in Greater St. Louis and a seat at the table with decision makers! We have multiple levels of membership available – including one that fits your needs!
