SPECIFIC PROCUREMENT NOTICE Invitation for Bids (IFB) Project: Greater Accra Resilient and Integrated Development Project Contract title: Reconstruction of Abbosey Okai Bridge Country: Ghana Credit No.: IDA-64100 RFB No: GH-MWH-219663-CW-RFB Issued on: October 14, 2026 The Government of Ghana has received financing from the World Bank toward the cost of the Greater Accra Resilient and Integrated Development Project and intends to apply part of the proceeds toward payments under the contract for Reconstruction of Abbosey Okai bridge . For this contract, the Borrower shall process the payments using the Direct Payment disbursement method, as defined in the World Bank’s Disbursement Guidelines for Investment Project Financing. The Ministry of Works, Housing and Water Resources invites sealed bids from eligible contractors for the Reconstruction of the Abbosey Okai Bridge . The project involves the demolition of the existing concrete arch bridge, approximately 47.5m long and 15.0m wide, which currently spans over the Odaw River. The existing structure is in a deteriorated condition, with visible concrete cover detachment, oxidized reinforcing steel bars, and vertical misalignment of the paving surface. The new bridge structure to be constructed consists of a 47.5m single-span deck , made of COR-TEN steel beams and reinforced concrete slabs , supported by reinforced concrete abutments with pile foundations . The bridge will have sixteen HL 1100 M (S460) steel beams, spaced at 0.95m, with a reinforced concrete slab (C40/50) placed on top. The abutments will be 6.50m high, 16.20m long, and 2.20m thick, with 24 reinforced concrete piles (diameter 1.20m, depth 25m) ensuring structural stability. The project also includes the elevation and reinstatement of the approach roads and surrounding areas affected by the bridge replacement. The existing vertical clearance of the bridge will be increased, preventing frequent submergence during floods. The bridge deck width will be maintained at 15m to guarantee continuity with the existing roadway. Additional works involve jet grouting consolidation at the abutments, with 130 jet grouting columns per abutment, extending 15m below the foundation slab, to mitigate soil liquefaction risks. Drainage modifications include DIA150mm pipes discharging rainwater directly into the river and covered side drains connecting to the existing drainage system. Traffic management and road diversions during construction will be a very critical
