General procurement notice for Procurement of Works for Construction of the Jangwani Bridge
The project will transform the flood-prone but economically important lower Msimbazi River Basin of Dar es Salaam through a set of integrated investments that aim to reduce the impact of flooding, catalyze sustainable urban development, and improve livability. The project duration is six years (2022 2028). The overall project implementation role and coordination function will be undertaken by the Presidents Office, Regional Administration and Local Government (PO-RALG) with some specific activities being implemented by the Dar es Salaam City Council (DCC) and the Tanzania National Roads Agency (TANROADS) being responsible for implementation of activities under Sub-Component 1.2(a): Construction of the Jangwani Bridge and related ancillary management activities under Component 4 of the Project. Project components and potential procurement opportunities Component 1: Msimbazi River Basin Development Infrastructure - This component provides an integrated, long-term solution to substantially reduce the impacts of floods in the lower Msimbazi River Basin that will improve hydraulic capacity of the river, provide an area for flood water detention, build resiliency of key transport infrastructure, regenerate valuable land assets to control encroachment in flood prone areas and allow for public recreation and urban development, and reduce degradation of the Msimbazi watershed. It consists of the following sub-components: Sub-Component 1.1: Flood Control Interventions - (a) recontouring the riverbed in the lower-basin flood plain area of the Msimbazis valley, including river channeling, excavation of flood plain/river dredging and construction of multi-level flood retention area (terracing works) to improve river conveyance; (b) carrying out riverbank protection works; (c) managing river sedimentation through the construction and operation of river maintenance depots, sediment and litter traps, and equipment; (d) carrying out construction supervision activities; (e) implementing analytical studies and detail designs (including environmental and social due diligence and stakeholder engagement) for prospective flood control and redevelopment investments in the Msimbazi river basin. Sub-Component 1.2: Resilient Transport Infrastructure - (a) widening and raising the Jangwani Bridge to accommodate flash flood events, including upgrading it to a multi-span bridge, raising embankments and improving stormwater conveyance; and (b) demolishing the extant Jangwani Bus Depot and relocating it (construction of new facilities) to a flood-proof new location. Sub-Component 1.3: Msimbazi City Park and Redevelopment Area - (a) carrying out a wetland and city park development in the lower Msimbazi river basin, including greening and mangrove revitalization, utilities infrastructure and equipment, and construction of streets and pathways, sports and recreation facilities, and mar |
