Cultural center conversion of cooperative wine cellar

This French public procurement tender seeks a general contractor to fully convert a cooperative wine cellar in Mèze, Occitanie, into a multi-purpose cultural center. The scope encompasses design, construction, operation, and maintenance (Design, Build, Operate, Maintain - DBOM). Practically, this means the selected firm will be responsible for everything from initial architectural plans and structural modifications to long-term facility management including potentially HVAC (45331000) and engineering services (71240000). The project involves adapting an existing building with "high heritage value" for cultural use, adding complexity due to preservation requirements. The tender is structured as a "marché global de performance" (performance contract), meaning the contractor's compensation is likely tied to meeting specified performance targets related to the operation of the cultural center after conversion.
