Experts appointed to assist investigation
Leading New Zealand engineering companies will assist the Department of Building and Housing with the technical investigation into the performance of the Canterbury Television, Pyne Gould Corporation, Forsyth Barr and Hotel Grand Chancellor buildings, Building and Construction Minister Maurice Williamson said today.
The companies are Beca Consultants; Dunning Thornton Ltd; StructureSmith; and Hyland Fatigue and Earthquake Engineering.
The Department has also appointed a panel of experts, chaired by construction law expert Mr Sherwyn Williams, which will provide guidance on the methodology of the investigations and peer review the findings.
Members of the panel include:
- Professor Nigel Priestley, former Professor of Structural Engineering at the University of California.
- Associate Professor Stefano Pampanin, a Structural Engineer
- Dr Helen Anderson, a seismologist
- Mr Peter Millar, a leading geotechnical engineer
- Mr Marshall Cook, past Adjunct Professor of Design at Unitec
- Mr Peter Fehl, who has extensive expertise in the construction industry
- Mr George Skimming, Director Special Projects at Wellington City Council
- Structural engineers Mr Adam Thornton of Dunning Thornton Ltd, Mr Rob Jury of Beca Consultants and Dr Clark Hyland of Hyland Fatigue and Earthquake Engineering
“The investigation is underway and is expected to be completed by 31 July 2011,” Mr Williamson said. “However, it is important to get this right rather than simply on time. It may be that more time is needed to undertake the work properly.”
“The investigation will establish and report on: the original design and construction of the buildings; the impact of any alterations; how the buildings
performed in the 4 September 2010 earthquake and the aftershocks; what assessments of the buildings’ stability/safety were made; and why the buildings collapsed or suffered serious damage on 22 February 2011.”
The Department is inviting members of the public to supply photographs, video recordings, and first-hand accounts of the state or performance of each building prior to, during, and after 22 February 2011.

He will bring to the panel expertise in geotechnical issues and foundation design.
- Mr Peter Fehl
Peter Fehl has spent most of his working life involved with the construction industry. The earlier years were spent working for major contractors, as well as for his own company, on civil engineering and commercial construction projects, in various site and managementpositions. Mr Fehl will bring to the panel expertise in the practises of the construction industry at the time these buildings were constructed.
- Mr George Skimming
George Skimming is currently the Director Special Projects at Wellington City Council. He will bring to the panel expertise in the consenting practices at the time these buildings were constructed.
- Mr Marshall Cook
Marshall Cook is a leading New Zealand architect with 40 years of experience in design and construction.

Technical Investigation into the Performance of Buildings in the Christchurch CBD in the 22 February Christchurch Aftershock
Terms of Reference
The Canterbury region suffered a severe earthquake on 4 September 2010 and an aftershock on Boxing Day. This was followed by another, more damaging aftershock on 22 February 2011. The magnitude 6.3 aftershock on 22 February 2011 caused significant damage to Christchurch, particularly the CBD, eastern, and southern suburbs, the Port Hills, and Lyttelton.
The high intensity of ground shaking led to a number of collapsed or seriously damaged buildings and a large number of people killed or seriously injured. It is important for New Zealanders that the reasons for the damage to buildings generally in the CBD, and to some particular buildings, are definitively established.
Matters for investigation
The buildings specified for detailed analysis include the: Pyne Gould Corporation; CTV; Forsyth Barr and Hotel Grand Chancellor buildings. Others may be specified for detailed analysis as information comes to hand during the investigation.
The purpose of this technical investigation into the performance of buildings in the Christchurch CBD during the 22 February aftershock, is to establish and report on:
- the original design and construction of the buildings;
- the impact of any alterations to the buildings;
- how the buildings performed in the 4 September 2010 earthquake, and the Boxing Day aftershock, in particular the impact on the buildings;
- what assessments, including the issuing of green stickers and any further structural assessments, were made about the buildings’ stability/safety following the 4 September 2010 earthquake, and the Boxing Day aftershock; and
- why these buildings collapsed or suffered serious damage.
The investigation will take into consideration:
- the design codes, construction methods, and building controls in force at the time the buildings were designed and constructed and changes over time as they applied to these buildings;
- knowledge that a competent structural / geotechnical engineer could reasonably be expected to have of the seismic hazard and ground conditions when these buildings were designed;
- changes over time to knowledge in these areas; and
- any policies or requirements of any agency to upgrade the structural performance of the buildings.
The investigation will use records of building design and construction, and will also obtain and invite evidence in the form of photographs, video recordings and first-hand accounts of the state or the performance, of the buildings prior to, during, and after the 22 February 2011 aftershock.
Matters outside the scope of the investigation
The investigation and report is to establish, where possible, the cause or causes of building failures. It is not intended to address issues of culpability or liability arising from the collapse of the building. These matters are outside the scope of the investigation.
The Department will prepare a detailed written report, setting out the conclusions drawn from this investigation about the matters referred to in the above section by 31 July 2011.
