Project managers are people who oversee construction projects in all fields including residential, commercial, and industrial. Project managers can gain their education through four-year colleges, associate degree programs at community colleges, as well as on the job training. A project manager may be located directly on-the-job, or in a home office setting. Their duties include overall management of construction projects, estimating, contracting, scheduling, day-to-day project activities, material procurement, quality assurance, and quality control. Project managers work in conjunction with field personnel to complete projects from startup until final completion.
