• Support effective and efficient contract management by enforcing governance, improving documentation and processes in collaboration with internal and external stakeholders.
• Track and report key performance metrics, contract awards, and delivery partner analysis to ensure performance visibility and commercial insight.
• Develop and manage performance indicators and continuous improvement systems, including open book processes, cost benchmarking, and value-for-money assessments.
• Collect, analyse, and apply unit cost data in line with organisational methodology to support accurate estimating and optioneering for capital schemes.
• Liaise with the Group Procurement team to ensure compliance with company procedures and integration with wider contractual arrangements.
• Provide contract packaging strategies that promote clarity, efficiency, and measurable outcomes.
• Maintain strong control over early warnings, compensation events, and the change control process to manage risk and cost exposure.
• Support the Lead Commercial Manager and wider management team with reporting, advice, and recommendations for improvements across all contract activities.

• Proven experience as a QS/Contract/Commercial Manager
