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.
Ships weighing up to 700 Tons are hoisted with the Synchrolift at Cape Town Harbour out of the water for maintenance of the ships typically every 5 years. The rails which are used to transfer the ships on land are in need of repairs. Replacement of the rails and improving the durability of the rail connecting mechanism at the transfer location where the Synchrolift connects to the fixed rails is necessary. Improving the drainage of the concrete slabs in the parking bay area’s is also an outcome of this project.
Detail design and construction monitoring of the replacement of foundations, structures and small part steel for its 3kV lines that are in need of replacement.
The project is divided into 5 Phases, spread out across 20km of railway tracks between various stations in the Cape Town area. The phasing is based on commuter volumes on the railway system and extent of corrosive decay of the steelwork observed on site.
Various types of structures at typical 67m spacing along the rail tracks suspend the electrical wires for the trains.
The appointment includes the survey of the existing infrastructure to identify the structures due for replacement. Structures with a rating of 2 or lower were allocated for replacement on more than 500 locations spread out over the 20km of railway track.
A contractor from Gauteng was appointed on a 2 year contract to the value of R80m to replace the structures. The contractor fabricates the steelwork in Gauteng and galvanizes and paints the steelwork with a Duplex paint system. All the steelwork is then transported by truck to Cape Town for erection under Permit conditions at night. Works started in July 2016 and is planned for completion in July 2018.
Conduct detail assessment of the existing main dry docks pumps and drain pumps. The scope also included the assessment of associated valves, motor efficiency, ventilation to the plant rooms and fire fighting capabilities and requirements.
Conduct detail assessment of the existing 10 wharf cranes. The scope also included the assessment of mechanical components, NDT, load testing and electrical supply.
