• Produce comprehensive material take-offs covering pipe, fittings, flanges, valves, steel sections, plate, consumables, and coatings.
• Estimate fabrication, welding, assembly, inspection, treatment, and installation activities using standard productivity rates and historical data.
• Review tender documentation to ensure full technical and commercial compliance.
• Identify risks, exclusions, assumptions, and gaps in scope.
• Ensure estimates account for ISO 3834-2 and ISO 1090 requirements, including welding procedures, qualifications, traceability, inspection, and documentation.
• Obtain, analyse, and consolidate quotations from suppliers and subcontractors.
• Assess costs for materials, specialist processes (e.g., NDT, coating, machining), transport, and outsourced fabrication.
• Evaluate commercial competitiveness and risks within the supply chain
• Develop preliminary schedules and delivery programmes to support tender submissions and resource planning.
• Liaise with engineering, production, procurement, and quality teams to validate estimate assumptions.
• Engage with clients to clarify technical queries and align expectations
• Contribute to bid reviews and approval processes.
• Support smooth handover of awarded projects to delivery teams, ensuring clarity on estimating assumptions and scope.

Continuous Improvement

• Maintain and enhance estimating databases, cost models, and productivity benchmarks.
