Building on Experience. Building for the Future.

Patterson & Dewar helps its clients build and maintain the infrastructures their communities need to compete in a global economy. This is our role, our mission, our heritage and our vision for the future.

Communities depend on infrastructure systems to drive local economic development and to deliver an improved quality of life for citizens. A community’s streets, airports, electricity, gas, telecommunications and water systems drive local economic development by providing the basic services required by residents, businesses and industries. Patterson & Dewar’s clients are stewards of the infrastructures they manage and develop, and their work assures the continuing economic viability of the communities they serve.

A community’s shared infrastructure improves quality of life for all citizens by giving them access to basic resources that make the community a better place to live and work—by providing a safe, nurturing and prosperous environment. Preserving and expanding local infrastructures requires operating as a public trust, which means observing conservative business practices, stewarding fiscal responsibilities, managing risk and sustaining the economic viability of the system.
