28 | Slab finish poses problems An adjacent pump house can pump millions of litres of water if need be to further increases the fire safety of the building. T T from page 26 Lobell Construction Sleepy Head Project: Sleepyhead Estate REGIONAL DFVELOPMENT “As things crop up we need to problem solve quickly to keep things on track and budget. There are a ot of creative people on the team who think outside the square and sometimes the simplest solution has been the best.” One tricky aspect was achieving the required finish on the concrete ground slab: “Once the slab is poured a company comes in with a grinding machine to polish it to give a textured ‘salt and pepper’ finish. “This requires a shallow grind and it’s the hardest finish to achieve, as when you’re pouring concrete there will always be ups and downs in the level. If the concrete is ground deeper the colour changes. “So normally a laser screen machine would be used to ensure a flat finish usual but because it is a very heavy machine it couldn’t be used in this case due to the slab design, which had two large layers of reinforcing steel. “The solution was to do small pours of 400sqm at a time. We had lots of meetings with the concrete pump operator, finishing team and engineers to keep a handle on quality and the end result was worth it.” Louis says safety is always at the forefront of every decision made and the client made sure this was a priority. Fire rating the facility ensures the delicate chemical process in which foam is made can be done safely. T Tto page 30 The entire facility is made to maintain a certain temperature with refrigerator panel insulating the roof. The TDI room cannot be protected with a sprinkler system so is isolated with a vast fire rated ceiling and the GIB Fyreline system has been used with the precast panels also providing protection. An adjacent pump house with seven enormous tanks to capture the rainwater from the foam plant roof and two diesel generators to pump millions of litres of water if need be further increases the fire safety of the building. Once roof and floors of the foam plant were completed the installation of the manufacturing plant took place.
