The end is nigh for the former Cadbury silos, and if the wind stays calm, you'll see "Stretch", the giant 74m crawler crane, help the demolition crew remove the top portion of the distinctive silos on Saturday 14 August.
The silos are approximately 30 metres high and weigh in at 70 tonne each. They'll be cut into thirds for removal and all steel will be recycled.
The crumb silos (or Burley Bins) were moved to the site in 1991. They were originally constructed in the late 1950s and early 1960s, located where Countdown is today. They were the idea of the engineer, Victor Burley, who was on the Cadbury Fry Pascall board, and was a Consultant Director to the New Zealand company as well. New chocolate crumb would be blown in and out of the bins by air pressure. When in the bins, the crumb would remain there in great condition until required for chocolate making.
In E. Barringer’s book, Sweet Success: The Story of Cadbury & Hudson in New Zealand, Barringer talks about a few ideas for how they would move the silos in the 1990s (helicopters, slicing and rebuilding them) though they also considered just building new ones. In the end though, they loaded them up on trucks (in an upright position) and drove them round to where they sit today!
Many people witnessed their journey in June 1991 and the scene it created was reported on the front page of the Otago Daily Times. The seven-hour relocation of the first silo involved 20 people, and hundreds more watched the proceedings during the night.
