Design Process Flow Chart For Bridge Replacement Projects
This chapter contains flowcharts for common types of projects completed by the Office of Design. The information in each flowchart provides a general workflow to successfully complete each project. The flowcharts contain a variety of tasks that may be ongoing throughout the project, or concurrent with other steps in the project development process. Special situations need to be addressed on a project by project basis. It is recommended that individuals make a customized checklist for each ongoing project to better assist managers and project teams.
