Last moments of the Grand Chancellor
The final section of the Hotel Grand Chancellor has been demolished.
Demolition workers from Fletcher Construction brought down the final, five-storey section of the building yesterday.
Christchurch Earthquake Recovery Authority engineer John O'Hagan said the demolition was the "most dangerous and difficult demolition undertaken since the earthquake so far".
The process of propping the building and lifting the roof was particularly complex.
At one point, engineers had two 4.5-tonne diggers on the roof of the building breaking pieces off so the crane could lift them down.
Workers will now focus on processing the debris remaining on the site.
Diggers and grinders will break down the rubble, separate the concrete from the steel and remove it from the site.
The remaining rubble will be ground down to gravel to use as fill on the site, and when the debris is cleared the ground-floor slab and the foundation will be removed.
All work is expected to be completed in three weeks.
