Stefanutti Stocks Geotechnical was appointed to undertake the piling work for the Vopak Terminal Durban (VTD) Growth 4 project in Durban Harbour’s Island View Complex. The contract was undertaken for client Vopak South Africa, with FLUOR managing the project on behalf of VTD.
Project execution and duration
The project’s kick-off date was 21 May 2018 and completion was scheduled for 17 September 2018. This was a fast-track project with very tight handover dates attached to each tank base, in order to give the follow-on contractor Stefanutti Stocks Coastal access to start the tank base construction on time. “We managed to hand over the piling works for all of the tanks bases and other structures a month earlier than scheduled,” says Teboho Motaung, Stefanutti Stocks Geotechnical project manager. “This was made possible through great team work and proper planning throughout the project.”
Piling scope of works
The most suitable piling solution was Continuous Flight Auger (CFA) piles, self-drilling anchor (SDA) micro-piles were also installed, as well as 180 linear metres of sheet piling. The CFA piles were installed to average depths of eighteen metres, the SDAs to depths of fourteen metres. The diameters are listed below:

Project challenges and successes
The challenges included the actual amount of production hours possible per day, as well as getting materials delivered into the Island View complex, which is a national key point. “The presence of other contractors mobilised on site, meant that the working areas became incredibly restricted and confined, making it difficult to execute the tasks as scheduled,” says Motaung. “Nevertheless, in spite of the above the project was delivered safely, the quality of our work was good, and above all, our client is happy – a great testament to the capability of the project team that made it all possible.”
