As a specialist sub-contractor to main contractor, Murray & Dickson Construction, Corestruc designed and installed the pre-cast roof structure for Magalies Water’s 50 mega-litre Mafenya Reservoir.
The columns of the reservoir were constructed as a combination of an in-situ stub with a pre-cast element erected to achieve the desired height. Pre-cast concrete slabs that serve as the roof planks are supported by a beam system tied to the top of the pre-cast columns.
To assist with drainage on completion, the in-situ stubs were cast to align with the camber of the roof.
The entire system comprised 36 columns, 40 beams and 290 pre-cast slabs, as well as a pre-cast coping system for finishing the roof-edge.
This project received an honourable mention at the 2017 Fulton Awards.
