JG Afrika is supervising the dualling of an approximately 30-km section of the N4 toll road between the M17 Garankuwa and R512 Brits interchanges on behalf of the Bakwena Toll Concessionaire.
We started working on the preliminary and detailed design of the two new carriageways on the east and west sides of the existing road in 2016, and a joint venture between Raubex and Enza Construction mobilised to site in mid-2018 to begin the three-year works programme.
The roughly R500-million project involves widening about seven large structures and lengthening a number of smaller structures. Moreover, it entails extensive earthworks with as much as 80% of the clays on the site to be replaced by rock fill.
It comprises a blend of suitable material sourced from site and about one million cubic metres of aggregate from a mine waste dump in the vicinity of the project to eliminate the need to open borrow pits.
Importantly, the project is providing numerous opportunities for small black-empowered businesses located within the vicinity of the road-dualisation project.
Notably, Bakwena Toll Concessionaire has committed to sourcing as much as 30% of all project requirements from local businesses, and as many as 10 emerging contractors are already working alongside the Raubex and Enza Construction JV at this early stage.
We have also engaged and involved the many community members who will participate in this project early on via two nominated officials from the City of Tshwane Metropolitan Municipality and the Steve Tshwete Local Municipality. This approach has ensured a spirit of goodwill between the contractors and the respective communities.
