I’m working with a well-established mechanical contractor that is looking to add an experienced Pre-Construction Manager to their team.

You’ll be involved in:
• Leading estimating and preconstruction strategy
• Conceptual through final estimating
• Design reviews and constructability
• Value engineering and cost development
• Working closely with operations, BIM, fabrication, purchasing, clients, and trade partners

The ideal candidate will have 3–7+ years of mechanical estimating/preconstruction experience, strong knowledge of HVAC, plumbing and piping systems, and experience with commercial or industrial projects.
