Senior Project Manager

Mechanical Project Manager (HVAC) - Charleston, SC

AC Corporation, A Crete United Company

AC Corporation, a Crete United company, is a well-established mechanical contractor with a long track record across North and South Carolina. We're hiring a Mechanical Project Manager in Charleston to own client projects from estimate through closeout and to grow long-term relationships with owner-direct customers.

This role suits a PM who wants real ownership: estimating, buyout, execution, margin, and the customer relationship. You'll manage a mix of owner-direct work, along with design-build and design-assist projects.

What you'll do

• Account management: Maintain and grow long-term owner-direct relationships with assigned key accounts through regular customer visits, progress updates, and coordination.
• Estimating: Price mechanical work through both site surveys and plan review.
• Project startup: Lead project setup and buyout, and coordinate with supervisors, foremen, and other trades.
• Purchasing: Issue purchase orders for equipment, materials, and subcontractors on time to protect the schedule.
• Scheduling: Build the project plan, including scope, resources, and timing, and coordinate with field superintendents, clients, general contractors, and subcontractors to meet completion dates.
• Change orders: Identify and price scope changes with the client or GC. Make sure field foremen understand the original scope so changes are caught early.
• Manpower: Work with trade superintendents to staff each project with the right number of workers at the right skill level. Keep manpower projections current.
• Financial control: Complete monthly billings, job cost reports, and manpower forecasts to protect estimated margins. Submit POs and subcontracts to accounting on time and resolve unapproved invoices.
• Quality: Make sure labor and materials meet project specifications through site visits, drawing and spec review, and ongoing client communication.
• Closeout: Deliver as-built drawings and O&M manuals, set warranty dates, complete punch list items, and collect final billing.
