CTV - the key players
Christchurch Earthquake 2011
The royal Commission identified a handful of key players in the CTV building as:
Gerald Shirtcliff, the CTV site's construction manager, initially refused to appear at the hearing and was later exposed as having faked his engineering qualifications.
The commissioners found ''serious issues'' with his credibility and was not ''up to the job''.
''We conclude that Mr Shirtcliff simply did not spend sufficient time on site in order to adequately perform the role of a construction manager.''
Alan Reay, principal of the firm that designed the CTV building, distanced himself from the project personally during the hearing but said his firm was "ultimately responsible" if design flaws were shown to be the reason for the collapse.
The commissioners found Reay should have supervised designer David Harding's work, given his lack of multi-storey experience.
''We do not accept that it was appropriate for Dr Reay to rely on Mr Harding's confidence that he could do the design and then leave him to it without putting any checks in place.''
David Harding, who led the design project for Alan Reay's company, had little experience in designing multi-storey buildings or in using a computer modelling programme called Etabs, with which he tested the seismic strength of the CTV design.
The commissioners found Harding was ''acting outside his competence'' on the CTV building, based ''fundamental deficiencies'' of the design.
''Mr Harding erred in his self-assessment of his competence and the confidence he had that he could design this building competently was unfounded.''
CHRISTCHURCH CITY COUNCIL
The council was scrutinised for the decision to issue the building's consent in 1986 and its rapid assessment procedures after the September and Boxing Day quakes in 2010.
The commissioners found consent should not have been granted.
''A result of the process followed was the issue of a building permit for a design that did not comply . . . a state of affairs that should not have eventuated.''
Bill Jones was the site foreman for Williams Construction, which built the CTV building.
The commissioners found Jones was a ''competent and experienced'' foreman, but lacked supervision on what was his first design-build contract.
''He was working in circumstances he appears to have been unused to . . . and without the guidance, mentoring and technical advice he might have received from a competent construction manager supervising him.''
The CTV building manager and owner of fourth-level tenant The Clinic came under fire at the hearing for having the building checked by structural engineer David Coatsworth only once after the September 2010 quake and not supplying the building plans.
The commissioners found Drew could have supplied the drawings when available and sought a post-Boxing Day quake inspection.
'' . . . There was potential for the damage to be worse than it appeared.''
