Who We Are

One Team Start To Finish

Eagan Building Group is a trusted builder and general contractor serving the St. Louis Metro Region, delivering start-to-finish solutions for industrial and commercial owners.

 

Founded in 2008, we bring 17+ years of proven experience helping owners move from concept to completion with clarity, accountability, and craftsmanship.

 

From preconstruction through final turnover, we lead new construction, renovations, and additions ranging from targeted improvements to complex, large-scale development. With designers, engineers, and construction professionals working as one integrated team, we simplify coordination, reduce handoffs, and protect what matters most: schedule, cost, and quality. One Team. Start To Finish.

 

The way we work is built into our name. EAGAN reflects the values behind every project: Engaged, Accountable, Genuine, Ambitious, and No Excuses. You’ll see it in how we communicate, how we plan, and how we lead: hands-on, disciplined, and focused on keeping you informed while the work gets done right.

What We Do

Our Mission

We aid in the design and construction of world-class facilities that strengthen our clients' operations and support long-term growth. By leveraging technology and the expertise of top construction talent, we help owners make confident decisions and move from concept to completion with clarity.

How We Work

We believe great projects are built on strong planning and even stronger communication. Our team stays engaged from the earliest conversations through closeout, aligning expectations, reducing surprises, and solving problems early. One Team Start To Finish isn't a slogan, it's our operating model.

Our Services

We provide comprehensive design-build services, including preconstruction consulting, construction management, and full project delivery. Our work includes new construction, renovations, building additions, metal buildings, and building repairs.

Markets We Serve

We partner with owners across industrial and manufacturing, healthcare and institutional, retail and hospitality, government, and corporate office environments. Each project is led with the same focus: protect schedule, costs, and quality while delivering a facility that performs.

"I have had the privilege of working with the Eagan team on several projects over the past three years. Every project validated my decision to choose Eagan. Not only are they great at all the upfront consultation to ensure that they understand my needs and have accurately quoted based on those needs, but the finished product is everything I expected and more every time! What sets Eagan apart is that they work hand in hand with the architect and design team to fully understand your needs upfront to ensure there are no surprises on the back end with the finished product or the costs."
