Generally speaking, a job superintendent or project superintendent is the contractor's representative at a construction site. The superintendent directs and coordinates the activities of the various trade groups such as Carpenters, Equipment Operators, Iron Workers, etc. - on site. Responsibilities include making sure that the work progress according to schedule, that material and equipment are delivered to the site on time, and that the activities of the various workers do not interfere with one another. The superintendent supervises all these activities by talking with and directing the foremen for the different trades or craft workers. Some of these foremen and their workers may be employed by the superintendent's own construction company, while others may be employed by other companies working on the job.
