Is a Construction Project Manager Role Office-based or in the Field?

Mostly office. A project manager owns budgets, schedules, submittals, change orders, owner communication and subcontractor coordination, which puts them at a desk or in meetings most of the day, with site visits as needed. The superintendent runs the field. Many hiring managers have parted ways with a PM who would not stay in the office, so they screen hard for it. If you want to be on site, say so early. An assistant superintendent, superintendent or field engineer track fits better, and a recruiter can steer you there instead of into an interview that stalls on the first question.
