Leadership & Team Management

• Lead, manage, and develop the estimating and cost modelling team.
• Recruit, train, and mentor team members to ensure capability and competency.
• Oversee performance management, goal setting, development planning, and welfare management.
• Manage team workload, priorities, and resource planning.

Cost Estimating Strategy & Governance

• Define, own, and maintain the organisation’s cost estimating and modelling strategies, processes, and standards.
• Update and control all relevant procedures, work instructions, and documentation.
• Ensure all estimates are produced in line with approved work breakdown and cost breakdown structures.
• Implement robust verification and validation procedures to ensure high‑quality outputs and positive assurance outcomes.

Project & Programme Support

• Ensure all projects and programmes have cost estimates supported by cost reports and clear basis‑of‑estimate documentation.
• Manage the production of three‑point cost estimates (baseline and scenario variants) for spending reviews, annual reporting, and scenario modelling.
• Produce cost estimate inputs for business cases (SOC, OBC, FBC).
• Review and analyse project cost estimates, providing insight on risks, opportunities, and areas requiring challenge.

Integration with Risk, Planning & Controls

• Work closely with risk and planning teams to deliver estimating uncertainty analysis (P50, P80) using reference class forecasting or quantitative risk analysis.
• Ensure cost estimates are aligned with project schedules to produce accurate cost phasing and cash flows.
• Support change control processes by producing updated baseline estimates when required.

Tools, Data & Continuous Improvement

• Maintain and develop cost estimation tools, models, and techniques.
• Manage the creation, maintenance, and operation of cost models.
• Identify, source, and manipulate data from multiple inputs, applying appropriate normalisation techniques.
• Stay informed on industry best practice and embed improvements into organisational processes.
• Support development of scenario management systems for recording and comparing scenario cost estimates.

Supply Chain & Procurement Support

• Procure and manage external cost estimating and modelling support services.
• Work collaboratively with Procurement to assess the quality of supplier bids and cost estimates.
• Ensure supply chain cost information is robust, consistent, and aligned with organisational standards.

Business Support & Risk Management

• Provide cost estimating expertise to support value‑for‑money assessments and site‑specific evaluations.
• Manage information appropriately and ensure compliance with governance requirements.
• Oversee budget and procurement management for the estimating function.
• Identify and manage risks associated with estimating processes, tools, and outputs.
