Led by our flagship brand, Dexter Construction, the Municipal Group has proven its expertise well beyond civil contracting. Over the course of many years and across a diverse range of projects, we have embraced our role as a leader and strategic partner, delivering a high degree of professionalism and responsibility. We strategically collaborate with owners and developers (and designers) at every stage of a project to streamline constructability and maximize value. As such, we are accustomed to leading design-build projects as well as public-private-partnerships and other non-traditional partnerships, including design, construction, financing, operations and maintenance responsibilities.
