Values & Commitment

Our approach is very simple: treat others as we would want to be treated.

It means employing the best and brightest in our industry and embracing their passion, creativity and ideas—and arming them with the latest technology to help them do their jobs.

It means forging real partnerships with suppliers and subcontractors that start with better project management and fair bidding practices and extends to a zero-tolerance hard-hat policy, industry-leading safety practices and one of the first contractor-led insurance programs.

And it means thinking about the communities in which we build as our own—projects that enhance them, sustainability practices that reduce waste and programs that give back to the people that share them.

For clients, our approach has created a fully integrated real estate, architecture, design, engineering and construction model that brings clients creative solutions that help their businesses succeed, with rigorous project management and tight fiscal responsibility that delivers their projects on schedule, on budget, and above and beyond expectations.

It’s a model that’s special in our industry. Because it’s special, we’re able to pursue the best projects and be selective about where we apply our craft. The feedback? Repeat and referral business from our clients that will keep us growing and innovating for years to come.

That’s our design build construction approach.
And it’s what makes Clayco one of our clients’ most valued partners.

Juneteenth Program

The Clayco Foundation Formed the Juneteenth Program and the Juneteenth Advisory Committee.

The Juneteenth Program and the Juneteenth Advisory Committee were formed to assist the Clayco Foundation with the solicitation and expenditure of donations for charitable purposes and to support education, awareness, and charitable causes related to Juneteenth and furthering anti racism causes across a wide spectrum.

Celebrated on June 19th of each calendar year, Juneteenth commemorates the day in 1865 when enslaved African Americans in Galveston, Texas learned they were free from slavery. Although the Emancipation Proclamation was signed in 1863, many African Americans were still enslaved in some states. Today, Juneteenth remains a celebration of freedom and hope.

Clayco Executive Chairman & Founder Bob Clark, and Executive Vice President Tom Sieckhaus, serve as Lead Mentors for this initiative, with Executive Vice President Otto Nichols, Clayco Shareholder, as Lead Trustee and members of the Advisory Committee advising and assisting the Foundation in all matters related to the Juneteenth Program.

The initial members of the Juneteenth Advisory Committee are Sandra Marks, Arnez Stevenson, Dan Lester, Jesse Sanders, Christol Crenshaw, Chaun Robinson, Troy Stephens, Jr. and Karen Howell.

Clayco Advanced Construction and Materials Laboratory (ACML)

The lab will be one of the finest research centers in the world for construction materials and methods

Construction of the new $6.5 million lab is expected to strengthen Missouri University of Science and Technology’s position as a national leader in addressing the challenges of aging public infrastructure. Construction officially begins Friday with a ceremonial groundbreaking.

When completed, the Clayco Advanced Construction Materials Laboratory will also expand the High-bay Structures Laboratory in Butler-Carlton Civil Engineering Hall to provide 16,000 square feet of research space for developing and testing new construction materials and methods.

The ACML also will support the university’s research focus on infrastructure and sustainability, including the rehabilitation of urban mass-transportation centers such as highways, bridges, tunnels, rail, airports, port and water navigation channels, and utility infrastructure.

Community Involvement

The Clayco culture is built on building more than structures. We believe our projects are building communities, and that the jobs don’t stop when the projects open.

We partner with the communities in which we operate, and we’re in it for the long haul, giving time, energy, and resources to the projects and charities that can help build these communities. Community involvement is, and will always be, an important part of our identity. We’re working with nonprofit organizations to support education, the arts, medical research, disaster relief and opportunities for minorities, youth and the underprivileged.
