SANDTON - The City of Sandton has said farewell to one of its oldest municipal buildings.

Formerly used for administrative purposes, the building was imploded this morning to make way for various new structures including commercial, residential and hospitality developments.

It took roughly 20 seconds for the former administrative building to fall to the ground.

Huge clouds of dust briefly engulfed surrounding buildings and trees as the structure was reduced to about 18,000 tons of rubble.

SA Demolishers' COO Naeem Joosab Said, "One was a nine story, the other one a five story [building]. You know we were bordering the library which was literally three and a half meters distance from the building we imploded. Everything went well, we're very pleased"

It's expected to take about a month for the rubble to be cleared, with construction on the new developments to start at the beginning of next year.
