Coordinate with utility customers, engineering teams, subcontractors, vendors, and field leadership to resolve technical and construction issues.
Plan work around outages, switching, clearance, grounding, energization, and access constraints in coordination with qualified utility and field personnel.
Enforce company and customer safety requirements; partner with Safety leadership to address hazards, investigate incidents, and implement preventive actions.
Oversee inspection and quality-control activities, punch lists, redlines, as-built documentation, testing coordination, and commissioning readiness.
Lead project kickoff, progress, client, subcontractor, safety, and closeout meetings; provide clear status reports and escalate material risks promptly.
Monitor subcontractor performance, contract compliance, manpower, deliverables, and payment applications; resolve issues affecting safety, quality, or schedule.
Support estimating and business development with constructability input, historical cost feedback, site assessments, and lessons learned.
Mentor project engineers, assistant project managers, and project support staff; establish clear accountability and promote effective field-office communication.
