Job description

The HPC Jobs Service supports local people into exciting, long-term careers across our Project. Senior Estimator Altrad HPC Permanent Job Responsibilities 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.​ Qualifications/Experience 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 For this role you must have evidence of right to work in the UK.
