ON SITE Dolomitic site provides technical challenges By Eamonn Ryan Motheo Construction Group is undertaking the bulk services work on a highly sensitive site in Tembisa, where 80% of the area is dolomitic. The nature of the geology has introduced considerable complexity to the low-cost housing project, with Motheo having to follow strict guidelines on the management of water run-off and erosion. T he open veld of Tembisa Extension 25, adjacent to Tembisa Hospital and a half- constructed church, and previously home to only a small settlement of homeless people, is in the process of becoming an almost R700- million mini city. Established in 1957, Tembisa is a major informal settlement to the north of Kempton Park on the East Rand in Gauteng. The site is approximately 58.391ha and will accommodate full subsidy and social housing units. Motheo Construction Group has been awarded a R145-million contract by the Development Bank of Southern Africa (DBSA) for bulk services of the residential project: a mega project for the Ekurhuleni Metropolitan Municipality’s Human Settlements department. The project will ultimately see the construction of 3 510 residential units of three and four storeys, with mostly two- and some one-bedroom units of flatlets of affordable housing in a slightly different format. Ekurhuleni has allocated R160-million of the total in its 2018/19 budget, with a further R524-million over the next three years, as noted in the Ekurhuleni 2017/18 Budget Highlights. Junithan Moodley, operations director of the Motheo Construction Group’s Civils division, explains that the next step is to appoint subcontractors in terms of relevant small and medium enterprises (SMEs), with preference being given to those from the area. “Our detailed programme for the scope of work will emphasise the critical path and completion date, which is an estimated 12 months for this package,” Moodley says. Well known in the construction industry as a leading provider of social housing, the Motheo Construction Four attenuation ponds are being constructed to manage water run-off caused by fl ash fl oods. 18 | CEC November 2018 www.civilsonline.co.za
