The engineers who wrote a damning report into the collapse of the CTV building say its strength was not affected by the demolition of a nearby structure.
The report authors Clark Hyland and Ashley Smith say shaking caused by the neighbouring Les Mills building demolition wasn't significant enough to weaken the building.
“They used procedures in the demo that weren’t approved including a wrecking ball which would have caused stronger vibrations,” Mr Smith says. “But we still have the view that it didn’t impair the seismic resistance [although] it would have certainly led to big vibrations in the building.”
CTV tenants who have given evidence at the hearing so far have reported an increased sense of shaking in the building after the September quake and questioned the building's strength.
