Project feasibility studies had been prepared, as well as social and environmental impact assessments, stakeholder engagement plan and other technical reports.
At the stage of preparation of preliminary technical-economic substantiation, the project was divided into three sections: 1. Zhinvali-Kvesheti; 2. Kvesheti-Kobi; 3. Kobi-Lars; the Kvesheti-Kobi section was considered a particularly critical section due to the circumstances under consideration. In turn, three corridors were identified on the Kvesheti-Kobi section (2), up to 40 primary alternatives (including zero alternative – not executing the project ) were considered, nine different alternatives were developed and explored.
The four alternatives proposed by the qualified experts of the international consulting organization were selected in the final report of the preliminary feasibility study, as a result of a multifunctional analysis. Subsequently, preparation of a more detailed feasibility studies was continued on the mentioned four alternatives.
Preferred direction was selected for each section, in line with the feasibility study. Appropriate alternatives were strongly recommended for each section, based on the multifunctional analysis that includes functional (route geometry, projected traffic intensity, number of road users, reduced travel time and costs), economic (total investment cost, total maintenance costs, economic benefits including the returns), environmental and social criteria (biodiversity, surface waters, groundwater, protected areas, soil and air pollution, landscape, resettlement needs, noise, vibration, cultural heritage sites, impacts on local population during construction and road use, frequency of traffic accidents)..
Accordingly, the selected Kvesheti-Kobi alternative was determined as the best solution, taking into account all the factors (technical, economical, in terms of CBA cost-effectiveness analysis and MCA multifunctional analysis).
