    About Us:
    Over its more than 50-year history, Septagon Construction has developed both simple and complex projects throughout the Midwest for both public and private sector clients.

    Before we build a building, we build a team. A team of planners. A team of workers. A team of subcontractors. A team of consultants. A team of...builders.

    The best team in the world needs the right tools to get the job done. In our business, those tools include more than equipment and machinery. They include relationships with local and regional government, design professionals, trade contractors and economic development. Technology and expertise. Experience and know-how. Management and logistics.

    Capability is different from execution. At Septagon, we separate ourselves from the competition by offering both. We focus on bringing the best people together, providing them with the best resources, and building the internal systems we need to manage your project from start to finish, ensuring that we do what we say we're going to do.
