Proudly Building Missouri for Over 100 Years
At KCI Construction, Missouri isn’t just where we work — it’s who we are. For more than a century, as a leading construction company in Missouri, we’ve helped shape the state’s roads, infrastructure, buildings, and communities.
From our offices in St. Louis and Springfield, we’ve grown from a family-owned firm into a 300+ employee-owned construction company delivering $200M+ projects across Missouri.
Our legacy spans generations. Our impact spans the state — from St. Louis to Wentzville, Columbia to Cape Girardeau, Springfield to Branson, and everywhere in between.
Learn More About Our HistoryMissouri-Born. Midwest-Built.
Founded in St. Louis in 1922, KCI has been on the ground for some of Missouri’s most critical and complex projects. We’ve built highways that connect cities, treatment plants that protect water sources, and facilities that serve generations to come.
As we’ve expanded our reach across Missouri, we’ve stayed true to our roots: growth, resilience, integrity, and teamwork. Now 100% employee-owned, every person on our team has a stake in the work — and a personal drive to do it right.
