LEED Contractor and Sustainable Construction

We are a leader in sustainable construction

Sustainability is our commitment, not a checklist.

It’s a responsibility we carry from planning through closeout and beyond. We integrate sustainable methods and materials that reduce impact and improve performance.

We built St. Louis’ first LEED Silver building, our own headquarters, constructed on a reclaimed brownfield site. Today, we’re a recognized LEED contractor, with multiple LEED-certified projects and more than a dozen historic restorations across the region.

Sustainability in Action

Our Sustainability Committee leads internal efforts to embed sustainable practices into everyday work, from project delivery to office operations.

We bring the same mindset to every job by building responsibly, reducing emissions and waste and investing in healthy, resilient communities.
