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!
