PROJECT ALERTS Procedural Conceptual Road infrastructure Road infrastructure Mali and Côte d’Ivoire Mozambique This road infrastructure and transport link project provides an alternative route to open up access from landlocked countries in the hinterland to the Gulf of Guinea and its international ports. Connecting Mali and Côte d'Ivoire, it involves the development of multinational road infrastructure and transport links along the Bamako- Zantiebougou-Kolondioeba-Boundiali-San Pedro corridor shared by Mali and Côte d’Ivoire. The works include the installation of solar-powered lighting systems in several locations, the construction of multipurpose centres for women’s associates, and the provision of farm produce processing kits. The project will be the largest of its type to be implemented in Mali. The project will connect Mali and the northern part of Guinea to San Pedro, an important international port in Côte d’Ivoire. The project consists of improvement and maintenance work on 140km of the corridor in Mali and 135km in Côte d’Ivoire. The works are expected to reduce travel times by 70% and significantly lower the cost of transportation between Mali and the Port of San Pedro. Upgrading of the Mueda–Negomano Road Phase II between Mueda-Roma (94km) in Cabo Delgado, Mozambique, is at the conceptual stage, through developer National Roads Administration Mozambique. It is a public-private partnership, classified as Open Tender, with the timing being 2019 onwards. The government has received financing from the African Development Fund and intends to apply part of the agreed amount to payments to finance design review studies for the Mueda–Negomano Road Project Phase II between Mueda-Roma (94km) in Cabo Delgado. Completion of this route is seen as strategic, as it is part of the project to consolidate the EN1National Highway, including the Mueda–Negomano section. The construction of the 70km Negomano–Roma road will start this year. Design Tender Power infrastructure Mining infrastructure Zimbabwe Mpumalanga The Bulawayo thermal power plant in Matabeleland, Zimbabwe, is due for refurbishment, with the Zimbabwe Power Company (ZPC) having shut down the station frequently due to problems caused by the antiquated machinery. The project is back to the design phase with ZPC having rejected the only financing advanced for pricing reasons. The delay is facilitated by the fact that Zimbabwe currently has an electricity oversupply, an official says, permitting it to shut down two power plants. The power stations, with a combined installed capacity of 190MW, had not been operating recently for a few weeks, according to ZPC’s power generation update. Munyati has a capacity to produce 100MW, while Bulawayo can produce 90MW. The country, which has until recently been battling to generate sufficient power to meet its consumption needs, has been relying on imports, particularly from neighbouring South Africa and Mozambique. ZPC used to import 300MW from Eskom of South Africa and 50MW from Mozambique’s hydro, Cahora Bassa. Exxaro proposes to relocate the Matla Coal Mine 1 surface infrastructure and access shaft from the farm Haasfontein 85 IS Portion 5 to the remaining extent of the Farm Bakenlaagte 84 IS, Mpumalanga. The shaft area with associated infrastructure, including the pollution control structures, will be approximately 69ha in extent. The mine has been in operation for more than 30 years. The current underground mining front is more than 17km from the existing surface infrastructure and access shaft. Relocation is essential to the continued economic viability of the mine. Opencast mining would have destroyed the wetlands completely, so the specific short wall mining method, combined with the river diversion, was a way of saving the wetlands. Through innovative engineering design and specialist environmental input from Golder Associates, Matla has been able to mine the coal underground with limited impact on the surface. Matla’s Mine 1 was currently on care and maintenance while the remaining mine shafts — Mine 2 and Mine 3 — were forecast to produce 7.7Mt in the 2017 financial year against Eskom’s contracted volumes of 10.1Mt. 32 | CEC May 2019 www.civilsonline.co.za
