<b>In the late 1960s the Wellington City Council surveyed all the commercial buildings in the city and marked nearly 200 as earthquake prone. The owners were given 15 years to either strengthen or demolish their buildings. The end result was mass demolition throughout the seventies and eighties.¹ Prompted by the Christchurch earthquakes, once again the council has published a list of over 630 earthquake prone buildings that need to be strengthened or demolished by 2030.²Of these earthquake prone buildings, the majority were built between 1880 and 1930, with 125 buildings appearing on the Wellington City Council Heritage Building List.³ This list accounts for a significant proportion of character buildings in the city. There is a danger that the aesthetic integrity of our city will be further damaged due to the urgent need to strengthen these buildings. Many of the building owners are resistant because of the high cost. By adapting these buildings to house co-workspaces, we can gain more than just the retention of the building’s heritage. The seismic upgrade provides the opportunity for the office space to be redesigned to suit changes in the ways we work. Through a design-based research approach this thesis proposes a framework that clarifies the process of adapting Wellington’s earthquake prone heritage buildings to accommodate co-working. This framework deals with the key concepts of program, structure and heritage. The framework is tested on one of Wellington’s earthquake prone heritage buildings, the Wellington Working Men’s Club, in order to demonstrate what can be gained from this strengthening process. ¹ Reid, J., “Hometown Boomtown,” in NZ On Screen (Wellington, 1983).</b> ² Wellington City Council, List of Earthquake Prone Buildings as at 06/03/2017.

This paper describes pounding damage sustained by buildings and bridges in the February 2011 Christchurch earthquake. Approximately 6% of buildings in Christchurch CBD were observed to have suffered some form of serious pounding damage. Almost all of this pounding damage occurred in masonry buildings, further highlighting their vulnerability to this phenomenon. Modern buildings were found to be vulnerable to pounding damage where overly stiff and strong ‘flashing’ components were installed in existing building separations. Soil variability is identified as a key aspect that amplifies the relative movement of buildings, and hence increases the likelihood of pounding damage. Pounding damage in bridges was found to be relatively minor and infrequent in the Christchurch earthquake.

A photograph captioned by BeckerFraserPhotos, "The demolition site of the Press building and Warners Hotel in Cathedral Square. The site has now been filled and compressed so that it provides a much pleasanter environment. From here, there is now a marvellous view of the Heritage Apartments building, which allows us a wider perspective of the building than was possible before".

A building on St Asaph Street has been demolished, exposing the interior structure of the adjoining building. The photographer comments, "The building that this one was part of has been demolished and the join looks very much like the exterior walls of an Anglo-Saxon house. It has been exposed due to the demolition of damaged buildings after the Christchurch earthquake".

A video of Press journalist Martin Van Beynen talking about the Canterbury Television Building which collapsed during the 22 February 2011 earthquake. Beynen investigates the construction manager of the building, Gerald Shirtcliff, who allegedly faked an engineering degree and stole the identity of an engineer he knew in South Africa. The video also includes footage of Shirtcliff giving evidence about the CTV Building at the Canterbury Earthquake Royal Commission.

Groups of emergency personnel conferring at the base of the collapsed Canterbury Television building on Madras Street in the aftermath of the 22 February 2011 earthquake. Behind them, other emergency personnel can be seen searching the ruins for trapped people. Smoke can be seen billowing from the remains of the building.

A video of the seminar "Seismic Assessment of Existing Masonry Buildings" presented by Professor Sergio Lagomarsino from the University of Genoa on 27 February 2014 at the University of Canterbury. The seminar demonstrated recent European research into modelling strategies, target performances and acceptance criteria for seismic assessment of masonry buildings.
