A design mistake by a structural engineer has been blamed for a floor collapse at Canterbury University during a packed hip-hop gig.
An independent investigation commissioned by the university said human error was behind the collapse during a performance by Savage at the newly-opened $2.5million student events centre.
It found a commercial structural engineer whose firm helped design the events centre failed to calculate a dynamic load for the floor, which meant its design was not adequate to support dancing by a large number of people.
Around 900 gig-goers were enjoying the upbeat concert on July 13 when the floor gave way.
No injuries were reported.
Vice-Chancellor Dr Rod Carr said although only a small area of the centre's total floor space was affected by the subsidence, the entire floor area would be strengthened, with work starting next week. It will be completed within four weeks.
"We have appreciated the way in which our contractors have responded positively to this situation," he said.
The new venue, with a capacity of 1400, opened in April after the university's student bar was badly damaged in the February 22, 2011 earthquake.
University of Canterbury Students' Association President, Erin Jackson, says students are looking forward to seeing the events centre re-open.
"We hope that Savage may even be able to come back to Christchurch some time to finish his set."
Dr Carr says the findings of the investigation have been shared with relevant contractors, but did not say exactly which firm was behind the design flaw.
