| Work Detail |
Concor completed the final foundation cast for the San Kraal Wind Energy Facility in Noupoort, South Africa, using an innovative environmental approach for the wind turbine foundation. This wind farm is part of the Koruson 1 Cluster, developed by EDF Renewables in partnership with HI Holdings, Gibbs Crede, and a local community trust. The project aims to add 420MW to South Africas energy grid. A significant innovation is the use of hollow-cast foundations, which reduce the developments concrete usage and carbon footprint. Concors construction process for the hollow wind turbine foundations was meticulous, involving multiple surveys to ensure strict adherence to the design. This precision was necessary to align the 40 post-tension duct cable sleeves for the tensioning cables within a tolerance of millimetres. A total of 168 setting-out points were calculated for each base, and a full-time Concor surveyor was on site to conduct all setting-out and verification survey work. Complex construction with precision engineering for wind turbine foundations The San Kraal Wind Energy Facility, located on the border of the Eastern and Northern Cape provinces, is one of three wind farms in the Koruson 1 Cluster. These wind farms, including Phezukomoya and Coleskop, each have an installed capacity of 140MW, collectively contributing 420MW to the grid through 78 wind turbines. The hollow-cast wind turbine foundations design is more complex than conventional methods, requiring precise engineering and labour-intensive work. Each foundation measures over 20 metres in diameter and around 3.3 metres deep, using over 400 cubic metres of 45 MPa concrete and an additional 18 cubic metres of 50 MPa concrete in the plinth. |
