Transportation construction inspectors are in charge of evaluating construction projects related to transportation, such as bridges, roads and sidewalks. They make sure that the project is compliant with local, state and federal regulations. In addition, they check to see that the project meets all contractual obligations. Because many of these projects take months or even years to complete, they often visit several times for mid-project evaluations. Based on their findings, they prepare written reports and take photographs for visual evidence.
