The South African National Roads Agency SOC (SANRAL) has identified the need to widen and improve two bridges on the N12 section 9 over the Orange River near Hopetown in the Northern Cape.
The widening of these structures namely B2482 and B2483 respectively, form part of an improvement project aimed at increasing the capacity of the existing route section as well as safety for roads users and pedestrians. The scope of works encompasses the widening and resurfacing of two said structures and the widening and realignment of the adjacent road sections. The section extends from km 2.568 to km 3.890, covering a total length of 1.32 km and provides a link between Britstown and Kimberley.
BVi is proud to be associated with such a prestigious project.
A 15kWp off-grid, ground-mount solar PV system was installed on a wooden sub-structure on Dassen Island.
The installation stores energy into a 48kWh Li-ion battery set and is integrated with a generator set as back-up.
The island is located 9km off Yzerforntein, Western Cape.
Since 2015 BVi has been involved in the design of five wind energy facilities throughout South Africa. One such facility near De Aar has been successfully completed, currently providing 100.5 MW of electricity to South Africa’s power grid, while two others (Perdekraal and Kangnas) are currently in construction with the remaining two (Excelsior and Golden Valley) scheduled to start construction in early 2019.
Combined, the five wind energy facilities will produce a total of 519.8 MW of electricity to the power grid of South Africa, relieving pressure currently put on our natural resources, such as coal, used to produce electricity.
Each wind energy facility has been designed to fit its local conditions.
Technical specifications at Perdekraal:
Turbine Model: Siemens SWT-2.346-108
Turbine Capacity: 2.3MW
Hub Height: 115m
Number of Turbines: 55
Foundation Diameter: 18.5m
Total Road Length: 30km
Table Grapes for export markets, packing- and cooling facility.
The facility is 10 500m² under roof with more than 500 people working in the facility. The packhouse receives 180 tons of grapes which is then cooled to 16 °C and then sorted and packed into 360 000 x 500 g punnets accurately made to weight and then assembled into pallets. The pallets is then cooled to -0.5 °C in 12 hours and then shipped in a total of 15 refrigerated shipping containers. The project had very tight timescales and the approaching harvest date cannot be moved or negotiated. A concurrent engineering approach was needed with designs and drawings being finalized for some disciplines after construction started. The adaption to Egyptian standards and way of doing things proved challenging together with language and distance from the site. BVi Northern Cape (Springbok) also had a full-time representative on site, spending almost 5 months in Egypt.
The BSG Warehouse, with an area of 20 000m², is located in Centurion, Gauteng.
