A CERA information sign on the fence in the Cathedral Square, placed to provide information to the public about the buildings seen from Cathedral Square. This one says "Clarendon Tower: This will be demolished. Currently CERA is working towards the appointment of an accredited demolistion contractor".

A proposed design by John Raven for a new cathedral, tied to a cordon fence. Clarendon Tower can be seen in the background. The photographer comments, "Someone is asking for designs for a new Christchurch Cathedral after it was announced that the old historical building will not be repaired, to be put on the fences through which people can see the de-construction of the old one. This design looks a great one to me".

In the aftermath of the 2010-2011 Canterbury earthquakes in New Zealand, the residual capacity and reparability of damaged reinforced concrete (RC) structures was an issue pertinent to building owners, insurers, and structural engineers. Three precast RC moment-resisting frame specimens were extracted during the demolition of the Clarendon Tower in Christchurch after sustaining earthquake damage. These specimens were subjected to quasi-static cyclic testing as part of a research program to determine the reparability of the building. It was concluded that the precast RC frames were able to be repaired and retrofitted to an enhanced strength capacity with no observed reduction in displacement capacity, although the frames with “shear-ductile” detailing exhibited less displacement ductility capacity and energy dissipation capacity than the more conventionally detailed RC frames. Furthermore, the cyclic test results from the earthquake-damaged RC frames were used to verify the predicted inelastic demands applied to the specimens during the 2010-2011 Canterbury earthquakes. https://www.concrete.org/publications/acistructuraljournal.aspx
