Core Responsibilities

• Manage and oversee all on-site construction activities, ensuring compliance with drawings, specifications, and method statements.
• Lead site teams and subcontractors, ensuring works are coordinated efficiently and delivered to programme.

• Ensure quality assurance processes are followed, including inspections, ITPs, and record keeping.
• Monitor progress against programme and proactively identify and mitigate risks to delivery.
• Manage site documentation, permits, and records to maintain a clear audit trail.
• Support commercial processes by identifying compensation events, changes, and early warnings in line with NEC4.

Experience & Knowledge

• Proven experience as a Site Manager within civil engineering or highways projects.
