Project Scope:

The three huge bulk sugar storage silos, are a well-known iconic Durban landmark, and have a particular relevance in Bosch Holdings history; as being the project that successfully launched the company.

The design was noted with great interest in the Sugar Industry around the world. With capacities of 120,000; 220,000; and 180,000 tonne sugar, these silos feature the design that won a prestigious award for outstanding engineering achievement in 1965 from the Institute of Civil Engineers.

Initial design commenced on the first silo in 1963 and at that time was one of the largest pre-cast, pre-stressed structures in the world. All the components of the pre-cast, pre-stressed structure were bonded with epoxy resin and the design was necessitated by Durban’s exceptional corrosive environment, which threatens reinforced concrete structures.

The second and third silos were added in 1968 and 1973 respectively and Bosch Projects have been their appointed Consulting Engineers on all these phases since 1963 including the construction of an adjacent bagged sugar store in 1990 which is approximately 15,000 m² and is designed for a storage capacity of 60,000 tons.

Bosch Projects has provided ongoing support around the maintenance requirements of the reinforced structures since erected and in 2016 Bosch Projects undertook the design and modification of the original ship loaders to accommodate changes to the quay and larger vessels .
