While these solutions could have cut down on production time, it turned out that high rainfall and the clayey platform made it almost impossible to achieve the daily minimum production from the start. In addition, the platform works could not proceed because the earthmoving vehicles were unable to work efficiently. In this regard, Franki requested a thick stone mattress in lieu of the soft soil platform. This was provided drastically, improving productivity. “In spite of six weeks being lost due to weather and related platform issues, works have already been completed at the Stadium and the Skydeck is still under progress – the newly agreed completion time was set for September 2018. The stone mattress, an additional piling rig and longer working hours have made that a certainty,” says Mongelard. The piling works started early June 2018 and, in terms of budget, the cost of Franki’s alternative solution will still be less than the original alternative solution – hence the project is within budget. “This is an important and high-profile contract in Mauritius and our success is based on excellent teamwork. The ability to work as a team and the support we have got, and always get, from Brian McDonald and the head office in general, is typical of Franki’s commitment to ensuring the best possible service to its clients,” concludes Mongelard.
