A MAN whose company designed the CTV building which was destroyed during the Christchurch earthquake has accepted full responsibility for its failings.
However he still points the finger at his engineer.
The Canterbury Earthquakes Royal Commission is looking at why the building collapsed on 22 February, killing 115 people.
Alan Reay, of design firm Alan Reay Consultants, was again giving evidence to the commission yesterday, Radio NZ reported.
Last time he appeared he admitted the CTV building didn’t meet his professional or personal standards.
He came to that conclusion after sitting through evidence during the hearing.
On Wednesday he said that while he thought at the time that the shear walls and gravity structure of the building were acceptable, he now accepts that the design put too much pressure on the concrete beam column joints.
They failed during the magnitude 6.3 quake, causing the building to pancake down.
He also said he made a mistake in trusting his engineer David Harding.
“This situation arose because of the trust I placed in what I understood to be a competent and appropriately experienced registered engineer.
“However, as I have said on previous occasions, if there are inadequacies in the design, as principal of the firm I accept responsibility for those inadequacies.”
Previous evidence had shown that Harding was employed with little experience in designing multi-storey buildings.
Mr Harding had offered his sympathy to those affected by the collapse, and had often wondered what he could have done differently.
He still believed the building was well designed to the codes of the day, but the the vertical acceleration of the quake was too much for its concrete support columns.
The eight-week inquiry concludes this week.
