Hotel Grand Chancellor, Christchurch

The Hotel Grand Chancellor was a major four star hotel in the centre of Christchurch in New Zealand, one of eleven Hotel Grand Chancellor establishments across Australia and New Zealand. The hotel was located at 161 Cashel Street, close to the city's City Mall central shopping precinct.

For a long time, it was the city's tallest building at 85 metres (279 ft) and 26 storeys, but was overtaken in 2009 by the 86 metres (282 ft) tall Pacific Tower.

The building was built in 1986 for office use by Forbes Construction. In 1996 it was converted to a hotel by Fletchers Construction with 15 floors of hotel accommodation, and 12 floors of car parking, also housing conference facilities for businesses.

The hotel survived the 7.1 magnitude Canterbury earthquake in 2010 and continued operation without any known structural damage. Five months later, while fully in use, the hotel was badly damaged in the 6.3 magnitude February 2011 Christchurch earthquake.

The building suffered structural damage, caused by the collapse of a key supporting shear wall "D5-6" located in the south-east corner of the building. The shear wall was responsible for roughly one-eighth of the Hotel Grand Chancellor's mass, primarily providing vertical support to the building. The damaged foundations lead to the visible leaning of the building to one side. Fear that the building would totally collapse hampered search and rescue missions in the vicinity. When searched, no survivors or bodies were found in the hotel.

A later investigation by the New Zealand Department of Building and Housing found that the risk of a staircase collapse and further serious structural damage could have occurred given the nature of the structural failure, but hadn't.

The building was eventually stabilised and on 4 March it was decided the building would be demolished over the following six months using a complicated deconstruction processes from the top downwards. On 25 May the public was told it would take over a year to demolish.

The roof of the hotel was removed in early November 2011. A protective fence was to be built around the building to catch debris from the demolition and then the demolition of the building was to proceed from January 2012.
