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
