These are two related but separate roles. While some of their duties and responsibilities overlap, there are also some key differences. Civil engineers primarily work away from the construction site, contributing to the project’s design plan and blueprints and ensuring compliance with various building codes, which informs the construction manager’s responsibilities. They often visit the construction site for quality assurance checks once construction has begun. Construction managers, however, always work on the construction site, managing the day-to-day operations of the various construction teams. While different, both roles are integral to the success of any construction project.
