suppliers to erect 450 tons of structural and miscellaneous teel. To construct the walkway over the busy South Boulevard and surrounding properties, the steel team had to enact careful planning to avoid extended closures of the thoroughfare. This task was accomplished through measures such as working on the weekends and utilizing a 900T mobile crane to max- imize the efficiency of setting multiple long span portions of the bridge. In order to erect these long spans, teams had to carefully plan the logistics and scheduling of assembling, transporting, and hoisting the box truss sections, weighing as much as 104 tons. A separate part of the project involved expanding United Wholesale Mortgage’s offices, which converted a former warehouse and utilized shipping containers for offices, cor- ridors, and other spaces. This sustainable re-use of materials provides a unique environment for employees and visitors. Impact(s): The United Wholesale Mortgage Pedestrian Bridge and Office Renovation is essential to efforts to drive Pontiac’s economy forward. Transforming spaces such as a 100 year old General Motors automotive factory and creating shared facilities helps connect this project to the community. In addition, these shared facilities will house programs for tutoring, literacy, arts and crafts, and sports activities that serve the youth of Pontiac. This project also has a massive impact on the AEC industry. A full 320 feet longer than the second longest pedestrian walkway in the United States, this project brings both prestige and pushes the boundaries of what is possible. Highlights: • Longest enclosed pedestrian walkway in the United States • Sustainable “cargo architecture” concept • Transformation of a 100 year old General Motors automo- tive factory
