The Exchange is a multi use, mixed program building. TheExchanges main principle is based upon the interaction betweencreative professionals and the general public. The idea is basedon the intertwining of three programmtic typologies: Showcase,Exchange and Production, and the benefits which can be drawnfrom this system.
The buildings form is a functional expression of the behaviour of soilparticles during liquefaction. Through utilising its natural verticalprocess as a circulation language and a way to arrange space TheExchange principle is meshed with the liquefaction properties togenerate a concept based around changing conditions.
The site connects High Street to Hereford Street, within the compactcore of the Christchurch Central Business District. The conceptdraws its potential from a previous laneway location, asserting theimportance of the development and reopening of these iconic sites
throughout the city.
The structure terminates at the north and south facades withcantilevered segments over the streets. The building is bound onthe west and east by neighbouring buildings. The building is a steelstructural grid of columns and beams, with two r einforced concreteservice cores and a sandblasted glass curtain wall facade.
The ground floor provides a largely open, uninterrupted space forconvenient pedestrian access between the two main roads. Coupledwith open-plan concept retail space, the ground floor aims to makeuse of a potentially high level of pedestrian traffic and entice visitorsup through the buildings higher levels.
The first and second levels have spaces for both work, productionand the exhibition of the various creative projects generated by thetenants. The idea is to have flexible space so that it can be used fora range of purposes depending on the event that day or night.

DENSE SEDIMENT
SATURATED LOOSE SEDIMENT
LIQUEFACTIONBEFORE EARTHQUAKE
The young sediment Christchurch is built on means the city is prone to the effects ofliquefaction during an earthquake event. Liquefaction variation is determined by theepicentre location, magnitude, depth, duration and geological conditions.Flat areas such as this, where the water table sits only a few meters under the surface,release a build up of pressure through s and boils and waterspouts in many areas andin lateral spreading and cracking near rivers. This occurs as waters are removed fromthe lower lying saturated loose sediment underground during the shaking. The wateris forced up through weak points in the denser sediment just below the surface. Asthis occurs the loss of water in the lower layers gives way to compaction, producing avariety of effects to the natural and built environment.

LATERAL SPREADING
Soil particles spread laterally under seismicstress, transferring volume from high areasto lower areas, especially near rivers andother bodies of water.
GROUNDWATER PRESSURE
As the soil compacts groundwater is forcedout of the saturated particles, surgingupwards and breaking through the densetop layer soil.
SAND BOILS / WATER FOUNTAINS
Resulting from the increase in groundwaterpressure, sand boils and water fountainsoccur through fissures in the surface layer.
GROUND SETTLEMENT
Over the duration of an earthquake theearth subsides as the seismic wavescompact and densify the loose, saturatedsecond layer soil.
