This operation aims at realizing technical studies, including the preparation of Tender Dossiers (DAO), and the provision of support services for the preparation of construction contracts for the development and maintenance by the method of Management and Maintenance by level of Service (GENIS) over a period of about 4 years of the unpaved road Kisangani - NiaNia - Beni road (RN4, 671.9 km).
The development will consist of two distinct operations: 1) the rehabilitation or substitution of the decks of 11 existing steel bridges (with spans ranging from 12 m to 240 m); and 2) the rehabilitation of part of the total length of the road (about 25% of linear length) for repair works taking into account the localized interventions conducted by the Office of Roads, financed by FONER within the maintenance program 2010-2011. This development will be carried out before the implementation of the maintenance, lasting four years, referred to above.
The objective of the initial development works and maintenance works to be carried out within the framework of these contracts is to ensure a level of service during the term of the contract.
The "standard level of service" that has been defined for Pro-Routes Project roads is in principle the following:
- Address the need for access of the population, the project aims at restoring the use of selected roads in any season for any vehicle;
- Provide a pick-up 4 × 2 to move safely at a minimum average speed of 40 km / h.
- Define the treatment of critical points and the gradual adjustment in compliance with: minimum construction costs, reduced maintenance requirements, and level of service limited to the accessibility.
