What You’ll Do Day-to-Day

The core responsibilities revolve around administrating subcontracts from inception to closeout, ensuring contracts meet cost, schedule, and performance standards.

The role involves managing the change order process, verifying subcontractor progress for billing, handling payment certifications, and tracking legal and commercial compliance throughout the project lifecycle.

Regular reporting, contract documentation, claims mitigation, and issue resolution with subcontractors are standard in your weekly workflow. You’ll also take a proactive approach to risk management and document control.

The position expects strong collaboration with teams, reviewing schedules and drawings, and supporting the project close-out process efficiently and accurately.

Cons – What to Consider
