Senior Estimator

The HPC Jobs Service supports local people into exciting, long-term careers across our Project.

• Estimate Preparation:
  Prepare detailed estimates for piping and mechanical work packages, covering direct labour, materials, equipment, preliminaries, subcontracted services, and indirect, and allowances.
• Basis of Estimate (BOE):
  Prepare and maintain comprehensive BOE documentation clearly defining scope assumptions, quantities, methodologies, pricing sources, and risk allowances.
• Work Breakdown Structure Alignment:
  Ensure estimates are fully mapped to the project's Work Breakdown Structure (WBS), Cost Breakdown Structure (CBS), and aligned to the Control Account framework.
• Data Analysis and Benchmarking:
  Utilise historical data, productivity norms, and benchmarking data (e.g., industry databases) to validate estimate inputs and assumptions.
• Supplier and Subcontractor Pricing:
  Liaise with procurement to analyse supplier quotations, subcontractor pricing, and bulk material pricing to ensure competitiveness and completeness.
• Schedule and Productivity Integration:
  Collaborate with planning and construction teams to ensure activity durations, labour resources, and installation rates reflect delivery strategies and site conditions.
• Change and Trend Support:
  Support change control, trend analysis, and re-estimation processes as project scope evolves.
• Commercial Support:
  Provide estimating inputs to commercial negotiations, contract awards, and cost target setting.
• Risk & Opportunity Analysis:
  Identify cost risks, quantify estimating uncertainty, and work closely with the Cost Forecasting & Estimating Manager and Risk teams to ensure proper integration into contingency and forecast scenarios.
• Forecasting Interface:
  Collaborate with Project Controls and Finance to ensure estimates are appropriately feeding into financial forecasts, cash flows, and budget development processes.
• Estimate Reviews and Governance:
  Lead and participate in estimate reviews, internal governance processes, and assurance reviews to ensure estimate robustness and alignment to project strategy.

• Degree or equivalent qualification in engineering, construction management, quantity surveying or a related discipline.
• Professional membership or certification desirable (e.g. AACE, RICS, ICES, or equivalent).
• Extensive estimating experience on large, complex infrastructure or energy projects.
• Experience supporting early stage estimate development for major infrastructure or energy projects, including support to funding gate approvals, commercial negotiations, and early design maturity phases.
• Deep knowledge of piping fabrication, mechanical installation, welding, NDT, and testing requirements.
• Strong understanding of estimating methodologies, BOE development, and WBS / CBS structures.
• Experience working with productivity norms and developing installation rates.
• Proficiency with estimating tools, databases, and Excel-based cost models.
• Understanding of schedule interfaces and how construction sequencing affects cost estimation.
• Collaborative working style within integrated project teams.
• Strong commercial awareness and understanding of cost risk exposure
