The text-book perfect implosion of Radio Network House could pave the way for controlled implosions throughout the city.
Canterbury Earthquake Recovery Network (Cera) staff who spoke to Mark Loizeaux, president of Controlled Demolition Inc, after the 8am implosion told him: "We should have been doing this a long time ago."
CERA chief executive Roger Sutton said all applications from building owners would be considered.
"It is up to the owners to decide how they intend to demolish their buildings, so that's the starting point of this process," he said.
Applications must meet strict safety and methodology criteria.
Radio Network House owner Greg Hedges said he hoped others would follow suit. "Now that we've got confidence with the technology perhaps other buildings will come down in this manner."
Mr Loizeaux, who headed the implosion, is a world expert in the field. This was his fourth implosions in as many weeks.
The modern, 14-storey Worcester St building was reduced to rubble in less than 10 seconds yesterday with a series of controlled detonations beginning in the basement. Initial reports indicated there was no damage to nearby buildings.
A seismograph reading taken during the implosion showed the resulting ground velocity was about 12 millimetres per second, similar to a large vehicle crawling across the site.
Mr Loizeaux said the implosion was approved partly because of the poor soil conditions beneath the building that provided the ultimate test for the technology.
"This area has the worst soil condition in the city," he said.
"It is one of the reasons they (Cera) approved this test because if the vibration is not going to be transmitted here, it is not going to be transmitted to ill effect of other structures elsewhere."
Now it has gone without a hitch, Mr Loizeaux said Christchurch, with its "target-rich environment" could look at further implosions.
