CAPEX Cost Estimator

GravitHy
is an innovative French company born with a global ambition to decarbonize the steel industry. Our goal is to produce large-scale, low-carbon green Direct Reduced Iron (DRI) using renewable and low-emission hydrogen. We aim to build, own, and operate our first green iron plant in southern France (2.3B€ Capex) , with the intention of replicating this model across Europe and beyond.

GravitHy is looking for a
CAPEX Cost Estimator (W/M).

The Cost Estimator supports the Project Department by developing, validating, and maintaining reliable cost estimates for GravitHy's industrial project.

He/She provides high-quality CAPEX estimates and benchmarking data across all project development phases, from early conceptual studies through FEED and detailed design, ensuring alignment with project objectives, budgets, and schedules.

The position is based in Paris, with possible travel to Fos-sur-Mer.

The Cost Estimator reports directly to the PMO.

Key Responsibilities :

1) Cost Estimate Activities

• Support with our external Engineering Company for FEED AACE Class 3 and 2 CAPEX estimates for our plant in Fos/mer, meeting tight budgets and timeframes.
• Perform in an Estimator capacity by developing estimates of labour, material quantities, and scope for early project or technology development phases across worldwide locations.
• Define and develop the estimating scope, ensuring all differences between competing concepts are captured.
• Produce bottom-up estimates derived from bulk material quantities, including infrastructure, modularisation, transport and installation, site labour (reflecting proposed constructability methods and practices), commissioning, indirect labour, client costs, engineering, and design.
• Assure the quality and consistency of estimates through checking, benchmarking, and validation processes.
• Write and maintain estimate plans, prepare and assemble estimate data, review estimates, and produce estimate basis documents with assumptions and qualifications.
• Maintain and continuously update cost and benchmarking databases with current costs, quotes, and market data.

• Contribute to the preparation of investment files in accordance with GravitHy's internal standards.
• Present and discuss estimates with the Leadership Team to ensure confidence and transparency in cost evaluations.
• Support project execution strategy by providing cost insights during FEED, EPCm, and detailed design phases.

3) Continuous Improvement and Methodology Development

• Contribute to the establishment of estimating methodologies, standards, and tools within the Project Department.
• Ensure full integration with project control tools (budget tracking, planning, and reporting).
• Support the development of estimating best practices, data management, and cost knowledge capitalisation.

Profile :

Education :

• Engineering degree in Quantity Surveying or equivalent relevant industry experience.
• Specialization in industrial cost estimation and French construction standards.
• Familiarity with EPC / EPCm project environments is an asset.

Experience :

• years of experience in cost estimating for large-scale industrial projects, including greenfield developments
• Proven expertise in EPC/EPCm estimating during FEED and detailed design phases
• Strong ability to develop bottom-up estimates from materials, labour, logistics, and client costs
• Proficiency in Microsoft Excel, estimating software tools, and AACE cost estimating practices
• Excellent oral and written communication skills in English and French
