Eiffage wins the public-private partnership contract for construction of a new prison facility in Vresse-sur-Semois (Belgium), for a total investment amount of €171 million

Eiffage, through Eiffage Concessions, has signed a DBFM (design, build, finance & maintain) contract with the Belgian Building Authority and the Federal Public Justice Service (FPJS) for the future Vresse-sur-Semois prison in Wallonia, Belgium. Total investment amounts to €171 million.

The new 39,000 m² prison facility will accommodate 312 units – with 284 medium-security and 28 restricted-security places. The project is targeting BREEAM Excellent certification.

The construction of the facility will be done by a consortium composed of Duchêne and Valens (Belgian subsidiaries of Eiffage Construction), Collignon (Belgian subsidiary of Eiffage Énergie Systèmes), together with the architects SCAU, ETAU and EOLE, and the engineering consultants Sweco Belgium, RT Group and ATS.

Fexim (Belgian subsidiary of Eiffage Énergie Systèmes) will provide maintenance for the 25 year contract duration, and Sodexo Belgium will provide catering, laundry and waste management services over the same period.

Handover of the complex is scheduled for 2029.

Vresse-sur-Semois will be the second prison facility the Group has built on behalf of the Belgian Building Authority and the FPJS in the country. Eiffage previously led the project to develop the detention centre in Marche-en-Famenne, which the Group will continue to operate and maintain until 2038.
