Three years of planning and complex tender negotiations have finally resulted in the commencement of major upgrade works at Hazelmere dam in the region of KwaZulu Natal, Durban, South Africa. The original structure, completed in the 1977, is approximately 44m high, 478m long and is an essential part of the water supply infrastructure for communities served by the Mdloti River.
Dr Mothersille was originally approached by French owned consultants Ingerop SA in 2012 but was formally engaged as lead technical consultant for the extensive post-tensioned rock anchor works in June 2015. This challenging project is programmed to last 24 months and will incorporate state-of-the art technology never before used in South Africa.
Further postings will be made as this fascinating project progresses.
