The temporary (10 years?) and cheap ($4-6 million) Anglican Cathedral being built a few hundred meters away from the old stone structure that was the centre of Christchurch. Both buildings (the original and this) have caused a lot of controversy, many wanting the old stone one to be repaired (the church want to demolish it), and this as a waste ...

Seismic retrofitting of unreinforced masonry buildings using posttensioning has been the topic of many recent experimental research projects. However, the performance of such retrofit designs in actual design level earthquakes has previously been poorly documented. In 1984 two stone masonry buildings within The Arts Centre of Christchurch received posttensioned seismic retrofits, which were subsequently subjected to design level seismic loads during the 2010/2011 Canterbury earthquake sequence. These 26 year old retrofits were part of a global scheme to strengthen and secure the historic building complex and were subject to considerable budgetary constraints. Given the limited resources available at the time of construction and the current degraded state of the steel posttension tendons, the posttensioned retrofits performed well in preventing major damage to the overall structure of the two buildings in the Canterbury earthquakes. When compared to other similar unretrofitted structures within The Arts Centre, it is demonstrated that the posttensioning significantly improved the in-plane and out-of-plane wall strength and the ability to limit residual wall displacements. The history of The Arts Centre buildings and the details of the Canterbury earthquakes is discussed, followed by examination of the performance of the posttension retrofits and the suitability of this technique for future retrofitting of other historic unreinforced masonry buildings. http://www.aees.org.au/downloads/conference-papers/2013-2/

One landscape colour digital photograph taken on 27 May 2013 of a retaining wall in Sumner Road which was replaced due to earthquake damage. The original wall was created using red volcanic rock. Many walls like this were built using the Hard Labour Gang from the Lyttelton Gaol. The replacement wall has a small section of stone installed to sho...

An aerial photograph looking west over the Arts Centre and Christ's College towards Hagley Park. The photograph has been captioned by BeckerFraserPhotos, "At the centre of this photo is a group of heritage stone buildings. Canterbury Museum and Christ's College were extensively earthquake strengthened prior to the EQs and re-opened to the public relatively quickly. The Arts Centre is undergoing extensive renovations. Hagley Park and the Botanic Gardens provide a richly colourful surrounding to these historic buildings".

A video of an interview with John Turner, owner of Ambience Tiling, about the restoration of the tiles in New Regent Street. Turner talks about working with SCE Stone & Design, who sent the sample tiles to China where they were machine replicated. The tiles took six to eight weeks to arrive, with about 10,500 new tiles produced. The video also includes an interview with Iain Taylor, a tiler at Ambience Tiling, about the retiling process.
