IN Brief:
- Neomat CAM has awarded an Eiffage-led consortium the earthworks and building package for its French cathode-material plant.
- Nearly 60,000m² of construction will require 37,000m³ of concrete, around 3,000 tonnes of reinforcement, and 6,200 tonnes of structural steel.
- Production is scheduled for late 2028 at a nominal capacity of 40,000 tonnes of cathode active material annually.
Eiffage will lead the consortium delivering earthworks and buildings for Neomat CAM’s cathode active material plant near Dunkirk, France, after the joint venture between XTC New Energy and Orano awarded one of the project’s main construction packages. The industrial investment is valued at nearly €500 million and forms part of the growing battery-materials cluster around Gravelines and Loon-Plage.
The consortium comprises Eiffage Génie Civil as lead contractor, working with Eiffage Construction, Eiffage Métal, Eiffage Route, Bemaco, and Ramery. Together they will deliver nearly 60,000m² of built area, including a production workshop of approximately 45,000m², a 5,900m² warehouse, a 5,650m² industrial water-treatment station, and a 2,500m² utilities area.
The material quantities underline the scale of the structural package. Eiffage expects the works to require around 37,000m³ of concrete, with production supported by a batching plant installed on site, together with approximately 3,000 tonnes of reinforcement and 6,200 tonnes of structural steel. Most of the steel is expected to be sourced from France and elsewhere in Europe.
Up to 400 people, primarily from the Dunkirk area, are expected to work on construction and fit-out through 2028. The package follows earlier preparatory works at the site, including the laying of the plant’s foundation stone in May and work associated with a tunnel intended to carry industrial effluent pipes.
Neomat CAM forms part of a wider materials venture between Orano and Chinese battery-materials producer XTC New Energy. The cathode plant is designed for nominal production of 40,000 tonnes of cathode active material each year once commissioned, which the developers equate to enough material for batteries used in as many as 500,000 electric vehicles annually. Production is scheduled to begin towards the end of 2028.
The construction programme combines the scale of a major industrial building with infrastructure specific to chemical and battery-material processing. The main workshop has to accommodate future production lines and process interfaces, while utilities, storage, industrial water treatment, and effluent systems must be delivered as parts of an integrated manufacturing facility rather than as isolated buildings.
Structural completion is therefore only one part of the programme. Foundations, frames, floors, and envelopes must be sequenced around the later installation of process equipment, pipework, electrical systems, controls, and specialist services. Tolerances and interfaces established during civil works can affect equipment installation months later, making coordination between construction and process engineering critical.
The decision to install a concrete batching plant on site reflects the volume and programme involved. Producing around 37,000m³ locally can reduce dependence on repeated deliveries from external ready-mix plants and provide greater control over pour sequencing, but it also requires aggregate storage, cement handling, quality control, vehicle movements, washout management, and environmental controls within the temporary works layout.
Structural steel presents a different logistics challenge. Around 6,200 tonnes has to be fabricated, transported, stored, and erected in a sequence that follows foundations and slabs across a substantial footprint. Using largely French and European steel gives the package a regional procurement component, although fabrication capacity, transport slots, and erection sequencing will still have to align with the main programme.
The project also sits within a part of northern France attracting several large industrial investments associated with electric vehicles and batteries. That concentration can support specialist supply chains, but it can also increase competition for civil engineering labour, fabrication capacity, temporary accommodation, plant, and specialist subcontractors. Mobilising up to 400 construction workers locally will therefore depend on more than the capacity of the lead consortium alone.
Once operational, Neomat CAM expects the plant to support around 400 direct and 200 indirect jobs, giving the project a longer economic horizon than the construction phase. Research and development activity is also intended to form part of the site, linking manufacturing capacity with the technical expertise needed to develop cathode materials.
The latest award moves the project firmly beyond enabling works and into its principal building programme. With almost 60,000m² to deliver before process commissioning and a late-2028 production target, the Eiffage consortium now carries responsibility for the physical platform on which one of the Dunkirk region’s major battery-material investments will operate.
