The document outlines the current state and challenges of non-building construction in the U.S., emphasizing the need for sustainability and detailing various rating systems and codes such as the Envision Rating System and the International Green Construction Code. It highlights significant infrastructure issues in Ohio, including the deteriorating conditions of roads, bridges, and water systems, alongside future budget shortfalls. Additionally, it introduces approaches for integrating sustainability into infrastructure projects, the role of civil engineers, and upcoming certification programs to promote standards in sustainable engineering.
