Kariba Dam Rehabilitation project (KDRP) - Reshaping of the plunge pool (PP) - 2nd phase (KDRP-PP-II) The purpose of this Action (KDRP-PP-II) is to allow the completion of the Action laid down in the 11th EDF Financing Agreement (FA) ZM/FED/031-570 (Kariba Dam Rehabilitation Project, KDRP).The Overall Objective of KDRP is to increase the reliability of supply and clean energy to Zambia and Zimbabwe and to minimize the risk of failure of the Kariba Dam. To do so, the project is supporting the Zambezi River Authority (ZRA) in carrying out the rehabilitation of the Kariba Dam through the stabilisation of its plunge pool and refurbishment of its spillway. Once the works are completed, the stability and proper functioning of the Kariba Dam will be ensured: the installed generation capacity of 2,130 MW will be maintained in the long term, while the risk of dam failure will be downgraded.KDRP is co-financed in parallel co-financing by the EU, WB, AfDB, SIDA and ZRA. The project has three distinct separate components:(1) Institutional support ¿ WB/AfDB, SIDA and ZRA funded(2) Plunge Pool reshaping ¿ EU funded(3) Refurbishment of the spillway ¿ WB/AfDB and SIDA fundedThus, in 2017, a EUR 49 million works contract was signed to carry out the reshaping of the plunge pool. The provided engineering design included the construction of a cofferdam to dewater the plunge pool and allow for its reshaping in the dry through excavation operations and the construction of a concrete fault protection slab. Unfortunately, this engineering design was based on geological assumptions that have proved to be insufficient and different from the current situation during the execution of the works. This has led to a number of modifications and additional works which have caused large delays and cost overruns.This Action aims at reinforcing the financial resources needed to complete the 2nd component of KDRP. &nbsp;Thus, the funds requested will cover:a)&nbsp;Works:a.1) Additional dewatering capacity, additional stabilization works following further required geotechnical investigations, additional grouting works and Art. 35/55 claims under the current works contract. Thus, funds available under this Action will top up the existing works contract under FA ZM/FED/031-570.a.2) A new Design and Build (D&amp;B) contract to be negotiated in case of termination of the current works contract. Thus, funds available under this Action and under FA ZM/FED/031-570 would be merged under this new D&amp;B contract.b)&nbsp;Supervisor Representative (SR) services: due to the shortcomings shown by the current SR financed by the WB/AfDB and the difficulties experienced because of the lack of contractual relationship with the EU/NAO; upon competition of the grout curtain, the SR, for solely the works in the plunge pool, will be replaced by a new Consultant to be procured.c)&nbsp;Legal representation / Legal advice / Conciliation and/or Arbitration services.The implementation modality, organizational set-up (including contractors and service providers) and responsibilities shall remain the same as set in the Financing Agreement ZM/FED/031-570, with the exception of the changes described in this document.
