Your Purpose in this Role

The Foreman is the field-level owner of making the mechanical system run and proving that it runs: refrigerant piping installed to specification, low voltage controls terminated and functional, factory and equipment start-ups completed and documented, and commissioning checklists tracked and closed out. This role also coordinates and quality-checks the controls subcontractor's field work to keep the mechanical system on schedule and functionally complete.
