About Septagon Construction

For decades, Septagon has served our many industrial, commercial and institutional customers with high quality construction services. By focusing on complete customer satisfaction and long-term relationships, we have built a solid reputation based on mutual trust, respect and integrity.

From six offices throughout Missouri and Iowa, Septagon serves customers as a single source construction partner. We provide a wide variety of design and construction services, and we work hard to exceed customer expectations.

Our Culture

Our customers are the reason we are here. Whether it’s a client’s first property or tenth, there’s pride in creating the infrastructure that will represent their business dream for years to come. With over 70 years of experience, Septagon has a proven track record of excellence in every aspect of the industry.

Our employees are the backbone of our company. We couldn’t succeed without their continued hard work and dedication to making the workplace a positive one. Each day, we remain committed to building a strong culture and safe workplace for our employees.

Our extensive safety program meets, and in some areas exceeds OSHA requirements. Employees are required to pass a drug screening and participate in a comprehensive safety orientation program before being allowed on a job site. We also provide regular training education to build a successful safety program and contract with a professional safety firm that provides additional counsel on all safety-related practices, inspections, and challenges.

Our Community

At Septagon Construction, we believe it’s important to be well-rooted in the community. We encourage all employees to participate in community events and are willing to provide on-the-clock employees to assist charitable organizations in our communities.

Our commitment to our community extends beyond the individuals. Each day, our team finds new ways to design and construct environmentally-friendly buildings for our communities through soil conservation, reduced material waste, reduced lifetime maintenance, and reduced utility costs. It’s important for us to create projects that are good for our environment while being good for your budget.

Our History

Septagon Construction’s roots date back to the mid-1940s as a single, general contracting company in mid-Missouri. Over the years, the original owner brought on partners who recruited and developed a management/ownership team to carry the vision forward.

Our vision and values of honesty, trust and commitment continue to be the main focus today.
