The dam is considered a high priority for ensuring adequacy of water resources for irrigation development and Power generation in the target area. Kajaki Dam was originally planned to be built in phases. The initial phase of construction objective was to provide water storage for irrigating the Helmand Valley and was completed in 1953 by American firm Morrison-Knudsen on contract for Afghanistan’s then royal government. The powerhouse which constructed during this phase, had a total installed capacity of 51.5 MW. Out of three turbines, two 16.5 MW turbines were installed by USAID in 1975, along with 110 Kilo-volt (kV) transmission lines and substations that distributed the generated energy to the region. In 1975 the 33 MW powerhouse was completed and hydropower generation became an important function Installation of unit 3 with 18.5MW capacity was only completed in 2016. Spillway gates were not included in this initial phase and therefore the dam was left limited in its ability to regulate flood flows and provide flood reduction benefits. The objectives of Kajaki Dam are: i) for irrigation water storage, ii) generation of hydroelectric power, and iii) water supply to the Helmand Valley. The service spillway gates are currently not installed, which limits the dam in its ability to generate more power and regulate flood flows due to the fact that the spillway is uncontrolled. Water from Kajaki Dam has a vital role for domestic water supply in an indirect way by recharging the shallow aquifers along the river and irrigation networks. \ Under the planned Phase II, GoIRA is planning  to complete the installation of spillway gates will allow Kajaki dam to regulate flood flow as well as provide additional irrigation and hydropower benefits to the Helmand Valley. Phase II also increase the generation capacity of the dam to 151.5 MW by constructing a new powerhouse next to the old powerhouse. Based on the signed agreements (Implementation Agreement & Power Purchase Agreement) between the Government of Afghanistan and 77 Construction USA Corporation in 2018 and a recent changes in project implementation approach, which was accepted by High Economic Council (HEC) on later 2019, the implementation of the Phase II project is now planned in two new phases, as follow: 1.         In the Phase 1 of the project, 77-Construction is responsible for increasing the capacity of the Dam by constructing an additional powerhouse with three units and total 100 MW of the installed capacity, next to the existing 51 MW powerhouse.  The three units (each of 33.3 MW) are planned to be installed with the existing water reservoir normal operation level of 1033.5 m.  Moreover, the raising of dam height by freeboard parapet wall will be done in this Phase. 2.         In the Phase 2, the normal operation level of the water reservoir will be increased from 1033.50 m to 1045 m by placing of radial gates on service spillway. Detailed Scope of Phase 1: •           Construction of Camp Facilitates. •           Construction of Downstream Cofferdam. •           Fabrication and Installation of Penstock. •           Construction of a New Powerhouse next to the existing, with 100M installed capacity included (3 x 33.33=100) Power Generating Units. •           Construction of Switchyard. •           Construction of Emergency Spillway. •           Supply and installation of Electro Mechanic Equipment. •           Construction of Parapet Wall on Crest of Dam Body. The implementation of Phase 1 will complete on February 2022, as per contract schedule. Detailed Scope of Phase 2: The Phase 2 of the project will be implemented in 18 months which is to increase the normal operation level of water reservoir from 1033.50 m.a.s.l. to 1045 m.a.s.l. by placing radial gates on service spillway and will be completed in two parts: Part A •           Completion of civil and structural works of service spillway. •           Fabrication and supply of Radial gates to project site. Part A will be started after the completion of Environmental and Social Impact Assessment (ESIA) & Resettlement Action Plan (RAP), hence the issuing of a legal permission or notice to proceed is required for the commencement of practical work. Part B •           Installation of Radial Gates, increasing of existing Normal Operation Level of reservoir from 1033.5 M to 1045 m a.s.l. Part B will only be started after the completion of government actions in terms of the implementation of Resettlement Action Plan (RAP) for the Project Affected People (PAP) impacted by the increased dam level., which are required before the extension of water reservoir and in accordance to the final reports of ESIA & RAP. The commencement of work will require need a legal permission or notice to proceed.  The completion of Phase 2 Part A,. is expected to take 12 months and Part B 6 months, as per contract schedules. OBJECTIVES OF THE INTERNATIONAL PANEL OF EXPERTS (IPE) Pursuant to the World Bank guidelines and policies the National Water Affairs Regulation Authority (NWARA) of the Government of Islamic Republic of Afghanistan (GoIRA) intends to establish an independent International Panel of Experts (IPE). The objective of the IPE is to review and advise on matter related to dam safety, aspects relevant to environmental and social assessment of the project and other critical aspects of the dam and the area surrounding the reservoir and provide advice to the  Project Management Team (PMT), such that each activity and assignment of the project is designed and completed in accordance international dam standards, within proposed investment cost and time frame and in full compliance with the WB rules and regulations and applicable Employer’s acts, rules and regulations. The NWARA seeks services of six individual international experts covering the areas of (1) Dam Designs and Construction Engineering for which this TOR is presented, (2) Hydrology / Hydraulic Engineering (3) Geology and Geotechnical Engineering, (4) Hydro / Electro Mechanical Engineering, (5) Environmental Safeguard and (6) Social Safeguard.  First four members will compose the project technical advisor panel (PTAP), and the last two members will compose the environmental and social advisory panel (ESAP). SCOPE OF WORK Primarily, the scope of the work will cover the technical, environmental and social components of Phase 1 and 2 of Kajaki Hydro Power Dam. When the IPE members reviews and makes assessment of main technical contents, it should not re-visit the overall scope of the project, general parameters and financial and economic feasibilities. The IPE members are required to collect site related information, to familiarize with the site conditions, scope of works, and skill assessment of the operator staff. It will then undertake safety and safeguard evaluation for the assignment. The owner staff will provide all required information, data and logistical assistance to the consultant. Site visit(s) may be agreed but it is not mandatory and it shall be freely agreed by each IPE member. Composition of the International Panel of Experts (IPE) IPE will consist of two group of experts, Project Technical Advisory Panel (PTAP) and Environmental and Social Advisory Panel (ESAP), and includes international experts of various expertise areas. The Panels will consist of six permanent members covering the areas of (1) Dam Designs and Construction Engineering, (2) Hydrology / Hydraulic Engineering (3) Geology and Geotechnical Engineering, (4) Hydro / Electro-Mechanical Engineering, (5) Environmental Safeguard and (6) Social Safeguard.  A member of PTAP will be selected by the other members to serve as Chairperson of the IPE and PTAP Panels (the natural candidate is the International Dam Design and Construction Specialist). The Chairperson will be responsible for coordinating activities of the IPE, mobilizing experts needed for the assignment in each working mission, finalizing reports, presiding at meetings, making final decisions and be responsible to the PTAP. One among the two members of the ESAP will be appointed Chairman of ESAP. Members of PTAP and ESAP are expected to work closely in order to minimize the constraints of this assignment. Project Technical Advisory Panel (PTAP) The primary objective of the PTAP is to provide an independent and high-level technical evaluation of the safety of the dam and optimization of power generation and more storage of water for Kajaki Project, and to propose solutions to improve safety of the dams and its associated structures to the acceptable safety standard corresponding to international practices.
