Project Description

The technical and economic studies relating to the establishment of an Output and Performance Based Road Contract (OPRC) on the RN2 road section Mbuji Mayi-Kasongo-Bukavu (1,020 km) were carried out and completed in February 2018.

Almost two years later, and following the modification of the road axes of the new project and the type of works to be carried out, it is necessary to update certain data from the studies of the Mbuji Mayi - Kabinda - Lubao section (332 km) in order to take into account the evolution of the situation on the ground and new development options.

Based on these considerations, the updating of the technical and economic study for the rehabilitation and development of the RN2 Mbuji Mayi-Kabinda-Lubao road (332 km), aims at:

  • determining the optimal option for the development of the road connecting the city of Mbuji Mayi to the city of Lubao via the city of Kabinda on the basis of a comparative evaluation of the possible development variants corresponding to different considerations of layout variants and / or service levels taking into account technical and economic criteria;
  • updating and / or finalizing the detailed technical studies of the chosen development option;
  • updating and / or preparing the Tender Dossier for the execution of the works, including their allotment into several sections in order to facilitate the implementation of the works.
