Republic of Liberia INFRASTRUCTURE IMPLEMENTATION UNIT MINISTRY OF PUBLIC WORKS P. O Box 9011 South Lynch Street REQUEST FOR EXPRESSIONS OF INTEREST Country: Liberia Grant No.: IDA-E7460 Project ID : P518023 Assignment Title: Consultancy Services for Feasibility Study, Economic and Financial Analysis and the Conceptual Engineering Design of Buchanan-Nimba (Legacy) Corridor Reference No .: LR-IIU-569555-CS-QCBS This Request for Expressions of Interest follows the General Procurement Notice for this project that appeared in the United Nations Development Business ( www.devbusiness.com ) and the World Bank website on August 17, 2026. The Government of Liberia has received a Grant Facility for Project Preparation (GFPP) from the International Development Association (IDA), toward the preparation of the Legacy Economy Corridor Project (LECO) and intends to apply part of the proceeds thereof toward payments for procuring services of a firm to conduct a Feasibility Study, Economic and Financial Analysis, and the Conceptual Engineering Design and Bidding Documents of Buchanan-Nimba (Legacy) Corridor. The Consulting Services ("the Services") include undertaking feasibility studies and conceptual/preliminary engineering design and preparation of Bidding Documents for two distinct road corridors: (i) Compound No. 3-Gban; and (ii) Palala-Yopea. The services will be in two phases as follows: Phase 1 - Feasibility Study: Confirm the physical definition and baseline condition of each corridor through reconnaissance and systematic surveys. Assess traffic demand, current and future mobility patterns, freight and agricultural movements, and non-motorized travel. Develop traffic forecasts and determine appropriate functional classification, design speed, and design criteria. Investigate alternative alignments and intervention standards and select the preferred option using a transparent multi-criteria framework. Undertake geotechnical, pavement-material, hydrological, and structural investigations sufficient for conceptual design and cost reliability. Assess climate and disaster risks and incorporate adaptation measures into engineering and maintenance strategies. Assess road safety risks and incorporate Safe System principles, appropriate speed management, pedestrian facilities and roadside treatments. Identify and develop plausible development scenarios - including development of Buchanan as an export gateway and agro-processing hub, upgrade of the Port of Buchanan, and reform of the Buchanan-Yekepa railway as a multi-user railway - that could materially affect corridor traffic demand; convene a Scenario Validation Workshop with relevant stakeholders; and agree two viable scenarios beyond BAU for full feasibility assessment. Undertake economic and financial feasibility under BAU and the two agreed development scenarios, with EIRR and NPV as primary outputs for each scenario; this is the central deliverable of Phase 1. Assess road standard requirements (unpaved gravel, DBST, asphalt pavement, staged upgrading) and phasing/packaging implications under each scenario, with full lifecycle cost analysis integrated into the economic appraisal. Undertake economic and financial feasibility, including EIRR, NPV, as primary outputs, and conduct sensitivity and risk analysis; this is the central deliverable of Phase 1. Assess affordability, life-cycle costs, and future O&M requirements. Undertake environmental and social screening and define the safeguards instruments required before construction. Assess land acquisition, ROW, livelihood, vulnerable-group, and community impacts and define mitigation requirements. Produce a defensible go/no-go and preferred-investment recommendation for each corridor. Phase 2 - Conceptual Design and Bidding Documents: Prepare conceptual design drawings, quantities, specifications, implementation strategy, and cost estimates. Assess local and regional contractor and materials-market capacity and use the findings to determin…
