The project, situated in the Northern Cape near Hothazel, called for the upgrade of existing material handling and construction of a multi-bin silo. Stefanutti Stocks Civils rose to the challenge to construct the silo by means of slip-forming, while having to deal with the extreme heat experienced in that region - the ambient temperatures range in the 40°C plus range. Stefanutti Stocks Civils modified the design in conjunction with design engineers DRA to render the construction of the challenging structure simpler and more conducive to slip forming. The whole silo was slid from the base, incorporating the columns and sliding the walls to accommodate the construction of the slab. The balance of the slip was then installed from work with specially designed supporting trusses to slide the complete structure to the top level. The volume of concrete used amounted to 50 m3 per metre.
