The Zanzibar International Airport is located 7 km south of Zanzibar Town. The airport is an important link to the island and its continuing operational efficiency provides a vital contribution to the current and future economy of Zanzibar. The Zanzibar airport runway has recently been fully rehabilitated and extended to enable larger aircrafts to operate directly to Zanzibar. Construction of New Passenger Terminal is in progress. For ensured smooth and efficient handling, maximizing efficiency and ensuring safety the existing degraded taxiways and apron should be fully rehabilitated, widened and extended in accordance with ICAO requirements. The following activities form part of this project:
(a) An Extension to the Existing Apron (additional area approx. 48,237 sqm); (b) Rehabilitation of the Existing Apron (approx. area 21,323 sqm); (c) Provision of a New Link Taxiway; (d) Rehabilitation and Widening of Taxiway A; (e) Rehabilitation and Widening of Taxiway B; (f) Reconstruction of Taxiway C; (g) An Extension to Taxiway C; (h) Emergency Repairs to the existing airport pavements (i) Implementation of mitigation and protection procedures on environmental issues.
The works include partial removal of existing surfacing, replacing and new construction with Marshall Asphalt wearing course and base-course with Hydrocarbon resisting sealing coat, bitumen bound base and granular material sub-base including earthworks, surface water drainage system, electrical and power supplies, aeronautical ground lighting and associated civil works, markings and other miscellaneous works.
The Democratic Republic of Congo et Germany have agreed on supporting the rehabilitation of the water supply installations in regional centres. Phase 1 of the project comprises the five centers Gandajika, Kabinda, Lodja, Mwene Ditu (East Kasai) and Mweka (West Kasai).
The programme aims at improving the technical and economic efficiency of the water supply installations and consequently at reducing the health risks linked to the use of bad water quality.
(1) Second National Urban Water Sector Reform Project – Supervision of Obudu Dam Rehabilitation Works:
The scope of works covers the Engineering Supervision of the Rehabilitation of Obudu Dam. Essentially, the scope of services is to control and supervise the construction of the spillway structure and rehabilitation of other dam facilities comprising civil works and mechanical works. The civil rehabilitation works include the construction of spillway structures, approach channel, overflow weir, spillway chute, stilling basin, deflection structure, draw-off arrangements, and crest re-profiling. In addition to temporary works which include the construction of a coffer dam. Mechanical works cover the modifications to the intake and downstream discharge chamber. Miscellaneous works comprise the construction of surface erosion control drainage, provision of a metrological station/ work boat and improvements to offices / workshops.
(2) Supervision of the Rehabilitation and Extension of the Water Production and Distribution System for Obudu: The proposed water supply scheme is designed to supply drinking water to Obudu town and the surrounding communities with an estimated total population of about 108,000 of which about 90,000 are in Obudu / Atekpe urban areas and about 20,000 in the surrounding towns. The scheme will be developed in two stages to supply 3,000 m3/day, in Stage I – for the year 2015, increasing to 6,552 m3/day, in the year 2025. The water supply scheme will be based on raw water abstracted from the existing impoundment on Abeb River (by means of the existing Obudu Dam). Raw water from the dam will be pumped by a Low Lift Pumping Station (LLPS) to the treatment plant, situated at the dam’s site. The treated water will be distributed to the communities by a high lift pumping station (HLPS), rising and gravity mains, elevated water tanks and distribution pipes.
The main objective of the project strategy is to obtain quality and security of the water supply. Mainly the women are affected by the bad supply situation and the frequency of breakdown of the pumps which forces them to return to the use of polluted water with its negative effects for the health of their families. The project aims at the installation of high quality pumps which are well adapted to the hydrogeological situation and guarantee quick reparation if necessary. In this context it is intended to improve the competence of the village to maintain the pumps and sustainably operate the systems. The project consists of two phases:
Phase 1 :
- Implementation of 220 human-operated pumps
- Rehabilitation of 20 wells
- Sanitary education
- Technical Assistance
- Implementation of 75 human-operated pumps
- Rehabilitation of 45 wells
- Sanitary education
- Technical Assistance
Serengeti Ecosystem Development and Conservation Project Integrated Protected Area and Rural Infrastructure Development and Financial Management — Tanzania
In 2012, the German Government committed to a new programme ‘Sustainable Natural Resource Management and Biodiversity Conservation’ to support the conservation and sustainable use of natural resources in the Selous and Serengeti Ecosystems, thereby contributing to rural development and ensuring that globally significant ecosystems remain intact. The target group of the programme is the predominantly poor rural population living in the vicinity of the protected areas of Serengeti National Park (SNP) and Selous Game Reserve (SGR).
The ‘Serengeti Ecosystem Development and Conservation Project’, as part of the above programme and module of the Financial Cooperation, addresses the conservation of biodiversity and sustainable management and utilization of natural resources in the Greater Serengeti Ecosystem, including Ngorongoro and Serengeti Districts, as well as the improvement of the livelihood of the underprivileged communities living in the area. The project objective is defined as: ‘Adequate utilization of the social and economic infrastructure provided as well as sustainable management and conservation of natural resources in Serengeti National Park and adjacent Serengeti and Ngorongoro Districts’.
The main objective of Project Management is to guide, assist, and advice the contractor on all matters that are related to planning, construction, commissioning and provisional acceptance of the works as well as recording any defects during the liability period.
Provision of consultancy services in connection with Engineering Design and Construction Supervision of Infrastructure Works at the Mombasa Port.
The services include Berths Upgrade Works (Rehabilitation works, strengthening, deepening and straightening works and Port Layout Improvement Works including (railway access and interchange improvement works; road access and interchange improvement works yard layout works.
The railway services in the east African region are inefficient and unreliable. At present, more 90 % of the freight handled at the sea port of Mombasa is transported by road.
The aim of the project is to optimise transportation within the east African region by implementing a harmonised railway system to the standard Gauge. The Kampala- Kigali railway encompasses two lots.
a) Lot 1 is Kampla – Mirama Hills with spurs to Kasese/Mpondwe and Muko with an estimated length of 904 km
b) Lot 2 is Mirama Hill- Kigali, with an estimated length of 200 km
The main objectives of the assignment are the construction supervision for the implementation of new works comprising a ferrous pipe installation of DN 1800 from Lower Ruvu Treatment Plant, Bagamoyo to the University Reservoirs, Dar es Salaam, and to meet the overall objective of DAWASA to accommodate the additional water supply to be provided by the expansion of the Lower Ruvu Water Treatment Plant from 180,000 m3/d to 270,000 m3/d as well as to improve the water supply to the residents in meeting the Millennium Challenge Account goals.
The DN 1800 Lower Ruvu Transmission Main to be laid in parallel to an existing concrete DN 1350 pipeline which runs along the Bagamoyo Road in the Bagamoyo District comprises a total length of approx. 56 km.
This project, once implemented shall provide reliable, affordable and sustainable water supply services to all categories of consumers in this part of the DAWASA designated area.
While the specific goal and objective is to provide and expand water supply in the designated DAWASA area, it is complimentary to several such systems and forms an important part of the aims of the Water Sector Development Sector.
