Reference No. (as per Procurement Plan): LB-LRA-513071-CS-INDV
1. BACKGROUND
The Ministry of Energy and Water (MOEW), through the Electricité du Liban (EDL) and the Litani River Authority (LRA), is implementing the Lebanon Renewable Energy and System Reinforcement Project (P180501), funded by the International Bank for Reconstruction and Development (IBRD).
The project aims to strengthen Lebanon’s electricity infrastructure through grid modernization, hydropower rehabilitation, and improved sector governance. Within this framework, the LRA is responsible for Component 2.2: Rehabilitation of the three Hydropower Plants (AbdelAl, Awali & Joun) and works to improve QARAOUN Dam Safety.
2. OBJECTIVE OF THE ASSIGNMENT
The Client (LRA) intends to appoint a Dam Safety Panel of Experts (DSPOE) for the Project to advise on dam safety assessment for Qaraoun dam, and other technical issues. who will be directly contracted by the LRA on a needs-driven basis.
The general task of the panel is to review all relevant design, engineering, construction and dam safety aspects. The members of DSPOE will be selected by the Client based on the required skill-mix. The members will constitute a group of high-level, internationally-recognized professionals.
