<p>The proposed Polihali Dam is a 163.5 m high (to non-overspill crest) concrete faced rock-filled dam with a side channel spillway as well as a 49.5 m high concrete faced rock-filled saddledam.</p>

<p>The C-O MISOA was initiated in late 2014 with support from the World Bank-managed multi-donor transboundary river basin development facility, the&Acirc; Cooperation in International Waters in Africa (CIWA). CIWA facilitated a consultative approach to develop the tools needed to identify sustainable regional investment opportunities in the Cubango-Okavango basin, an area of global environmental significance threatened by deep, persistent poverty within the three strong middle-income member countries;&Acirc; Angola, Namibia and Botswana.</p>

<p>Orange River System &#40;ORS&#41; is one of the most highly developed River Systems in Southern Africa. In September 2015, Namibia and South Africa, under the auspices of the PWC, commissioned the Noordoewer / Vioolsdrift Dam (NVD) Feasibility Study, which aimed at identifying and optimising the best development dam size(s), site(s) and sequence of dam developments in the ORS needed to achieve the overall catchment objectives, to re-regulate the flows for ecological needs and to increase the yield in the Orange River System for use by both RSA and Namibia. The study was completed in May 2020.</p><p>The study investigated many possible options and in 2016 initially concluded that the optimal NVD would have a wall height of about 73 m, with a storage capacity of 2,800 million m3 and would be of concrete faced rock fill type (CFRD).</p><p>Certain limited further feasibility studies are required before the project can proceed to implementation. Such studies would include at least an independent review of the above findings, the finalisation of the exact parameters for the recommended optimal NVD in terms of size, site and type, and obtaining environmental authorisation for implementation.</p><p>The development of the NVD project will involve the following further stages:</p><ul><li>Further feasibility studies</li><li>Detailed designs, procurement and construction</li></ul><p>The initially proposed NVD was sized as a concrete face rockfill dam (CFRD), with parameters as set out below, consisting of a side spillway, outlet works, hydroelectric plant, river flow gauging weir, etc. Parameter Description: Full Supply Level (FSL)-230 masl; Freeboard-12.5 m; Non-Overspill Crest (NOC)-242.5 masl; Lowest River Bed Level-162 masl; Dam Height up to NOC Level-80.5 m; Crest Length-1 km; Crest Width-10 m; and Embankment Slopes- 1V:1.4H. However, the exact dam parameters will be confirmed on completion of the further studies referred to above.<br></p><p>The project serves a planned infrastructure asset of another sector, but there is less than 50% overlap in the geography serviced by the proposed project and the other sector planned asset.</p><p>This planned project is part of the entire Orange River System &#40;ORS&#41; and is supported from the existing regulation infrastructure/dams upstream in Lesotho and South Africa.</p>

<p>The AXIS Project aims to facilitate the development of an African internet infrastructure through policy and regulatory reform, capacity building and technical assistance. Development of an African internet infrastructure refers to the establishment of regional internet exchange points (IXPs) and internet carriers.</p>

<p>The AXIS Project is being implemented through two phases. Phase I consists of capacity building to support the establishment of national IXPs through providing a series of two workshops for stakeholders and the Internet Service Provider Association (ISPA) on  I) best practice and benefits of IXP and II) technical assistance through workshops which will cover the technical and administrative skills needed to set up, operate, and administer an IXP.</p>

<p>Phase II focuses on supporting establishment of Regional IXP and Regional Internet Carrier through provisioning Capacity building workshops on best practice and benefits of setting up RIXP/IC and providing technical assistance.</p>

<p>The AXIS Project is a flagship project of the African Regional Action Plan on Knowledge Economy (ARAPKE) endorsed by the African Union Executive Council.</p>

<p>The Nacala Railway Corridor Project will transport approximately 18 million tons of coal, derived from the expansion of Moatize Mine (Mozambique) through a railway system connecting the existing mine in Moatize to a new coal terminal in Nacala Velha (Mozambique). The project was funded by Vale, and has the potential of being developed into a transport corridor for Mozambique&#39;s Tete Province, and potentially Zambia and the Democratic Republic of Congo (DRC). The railway line is located in the north-western region of Mozambique, starting at Moatize in the Tete Province, going through Malawi and connecting to the existing railway network at Nkaya Junction. From here the route follows the exisitng alignment through Entre Lagos, Cuamba and Nampula. Finally, in the region of Monapo, the railway follows a new route up to the new coal terminal at Nacala Velha. Aurecon previously developed FEL 1, 2 and 3 (Front End Loading) studies for the development of the corridor. The Detail Design (FEL4), included the design of the entire railway line and its associated infrastructure from the mine loadout station to the car dumper at the proposed new port terminal at Nacala Velha. The railway line is designed for a 20.5t axle load. Apart from providing an export conduit for the client, the rail corridor will have direct- and indirect social benefits to the larger community in terms of job creation, improved mobility (passenger train services) and the economic development of the region.</p>

The coal terminal will have the capacity to handle 30 million tons per annum.</p>

<p>Expansion of Nacala Port container terminal (Mozambique) to accommodate 600 000 TEUs per annum.</p>

This project is part of the expansions at 2020 gap airports Phase 1. It will see upgrades at the N'djili Airport (also known as the Kinshasa International Airport).

<p>The project entails the construction of a 218&Acirc; km, being 142 km at Mozambique side and 76 km at Malawi side,&Acirc; 400 kV (initially to be operated at&Acirc; 220 kV) power line from Matambo substation, in Mozambique, to Phombeya, north of Malawi's commercial capital, Blantyre. The first assignment will involve the design, supply and installation of the 400 kV overhead transmission line from the Mozambique-Malawi border to Phombeya substation including construction of the landing bay at 400kV Phombeya substation related to the Malawian side. The second&Acirc; assignments include extension/ upgrading of Matambo substation form 220 kV to 400 kV&Acirc; and upgrading of SCADA systems (EDM) related to Mozambique side.</p>
