The stakeholders in the Canterbury TV Building Collapse 2011 include:
Canterbury Television (CTV): The main tenant of the building1.
King’s Education language school: The school had 64 foreign students from Japan, China, the Philippines, Thailand, and South Korea in the building2.
Medical Centre Workers: They were present in the building at the time of the collapse2.
Alan Reay Consultants: The structural design engineer for the CTV Building1.
Alun Wilke Associates Architects: The architecture firm for the CTV Building1.
Madras Equities: The owner of the building since 19911.
Christchurch City Council: They gave building consent in September 19861.
David Harding: The engineer who made fundamental errors in designing the CTV Building3.
Alan Reay: The boss of David Harding who handed sole responsibility for the design over to Harding3.
Each of these stakeholders had a role to play in the events leading up to the collapse, and were affected by it in different ways.
Prerequisites
- 2010/09/04 Canterbury earthquake, 2010/12/26 aftershock (4.9 magnitude)
- building was still safe
Analysis (problem recognization)
- Significant change in design philosophy from non-ductile design of a reinforced concrete structure to a ductile approach
root cause, the engineer not good
while management bad → led to issues
Code of Conduct (ethical implication)
HKIE 1.6 (Alan Reay)
HKIE 1.7 (The engineer)
1.6 accept responsibility for his actions and ensure that persons to whom he delegates authority are sufficiently

- The Institution of Professional Engineers (Ipenz) lodged a complaint in December 2012 against Dr Alan Reay
- Ipenz believed Dr Reay had failed to disclose his involvement in the design and construction of the CTV building when he applied for registration in April 2011
- giving his inexperienced structural engineer David Harding “sole responsibility” for the building’s mid-1980s design.
- Dr Reay was also criticised for not reviewing his designer’s final plans.
- Last year, he resigned from Ipenz and avoided its disciplinary process.

- The shear wall was on the north side, outside the floor plan altogether
- ETABS was a rudimentary program. The deflection data it produced was for a single point at the centre of mass for each storey of a building, not the corners,
- while thinking his work was being reviewed by his boss. It wasn’t. Reay thought Harding was up to the job; Harding thought Reay was shepherding him through his first full multi-storey design project.
- no history working on multi-storey designs
