BackgroundThe Federal Government of Nigeria, with financing from the World Bank, is implementing the Sustainable Power and Irrigation for Nigeria (SPIN) Project to strengthen dam safety, improve water resource management, and expand irrigation infrastructure across participating states. The Project builds on the Transforming Irrigation Management in Nigeria (TRIMING) Project and aims to rehabilitate approximately 40,000 hectares of irrigated command areas nationwide while improving dam safety and water storage management across Nigeria's dams.The Kware Irrigation Scheme, located in Kware Local Government Area, Sokoto State, was originally constructed in 1954 and derives its water supply from Kware Lake, formed by the Kware Water Conservation Structure. An Update Design Report (May 2026) proposes extending the Scheme by 500 hectares net cultural command area (550 hectares gross) through rehabilitation of the reservoir, intake works, canal network, and associated hydraulic structures.An independent technical review of the Engineering Design Report and Bill of Engineering Measurement and Evaluation (BEME) classified the submission as requiring significant revision, citing unresolved technical, cost, and economic viability concerns, including incomplete construction drawings, an unsubstantiated increase in the height of the Water Conservation Structure, a unit cost significantly above the World Bank benchmark, and a negative economic return. The Sokoto State Ministry of Agriculture and Natural Resources, through the SPIN Project Implementation Unit (the "Client"), now wishes to engage an independent Consulting Firm to undertake a comprehensive Detailed Design Review to bring the Scheme to a bankable, cost-effective, and economically viable standard suitable for World Bank financing.2. Objective and Scope of Services• The objective of the assignment is to undertake a comprehensive, independent Detailed Design Review of the Kware Irrigation Scheme Update Design, in order to verify, validate, complete, and, where necessary, revise the engineering design, cost estimates, and economic analysis, delivering a technically sound, cost-optimized, and economically viable rehabilitation design ready for implementation. The Scope of Services includes, but is not limited to:• Review and verification of topographic, hydrological, geotechnical, and soil investigation data, including supplementary field surveys where gaps exist;• Independent hydraulic and structural review of the Water Conservation Structure, intake structure, protective dyke, and reinforced concrete irrigation delivery sump, and preparation of a Dam Safety Review and Dam Safety Management Plan;• Review of the canal network, hydraulic structures, and drainage design, and preparation/reconciliation of complete construction drawings (AutoCAD and PDF);• Review, verification, and reconciliation of the Bill of Engineering Measurement and Evaluation (BEME), inclusive of VAT and appropriate contingencies, and value engineering to approach the World Bank benchmark unit cost of USD 8,000/ha;• Update of the economic and financial analysis (NPV, IRR, benefit-cost ratio, sensitivity analysis) with measures to achieve a positive economic return;• Review and strengthening of institutional arrangements for Water Users Associations and Participatory Irrigation Management, incorporation of domestic/livestock water access and canal protection measures, and confirmation of compliance with World Bank Environmental and Social Standards;• Climate resilience assessment, asset management planning, construction methodology and procurement-readiness review, and preparation of an Operation and Maintenance Framework.The full Terms of Reference (TOR) describing the detailed scope, methodology, deliverables, and reporting requirements will be provided to shortlisted firms.3.
