• Assist with measurement and verification of completed work, review of payment application backup, and maintenance of records supporting quantities and progress.
• Support evaluation and documentation of potential changes, differing site conditions, claims, and time impacts by maintaining contemporaneous records and coordinating technical input.
• Coordinate interfaces among the owner, contractor, designer, inspectors, utility representatives, operations staff, and other project stakeholders.
• Support environmental, permit, community-impact, traffic, access, and site logistics coordination as required for the work.
• Assist with testing, commissioning, punch-list management, as-built record review, closeout, and handover activities.
• Promote a strong culture of health, safety, quality, inclusion, and collaboration, and promptly escalate significant site risks or concerns.

• Experience reviewing contractor submittals, RFIs, work plans, method statements, inspection records, schedules, and change documentation.
