Dust rises from fallen buildings on Tuam Street shortly after the 22 February earthquake. The photographer comments, "Just after the aftershock settled on Tuesday afternoon, myself and colleagues fled our Tuam Street office to absolute devastation outside. We couldn't see more than a block in either direction due to the clouds of dust that had arisen from buildings that had just collapsed. Above is looking along Tuam Street to the corner of Manchester Street where a number of buildings have just collapsed. This is 1pm and the sky was previously reasonably clear - this is all dust. From here, we picked up our vehicles from the CCC car park and headed out to get out of the chaos to a position where we could check on loved ones".

People walk down Colombo Street past collapsed buildings shortly after the 22 February earthquake. The photographer comments, "Just after the aftershock settled on Tuesday afternoon, myself and colleagues fled our Tuam Street office to absolute devastation outside. We couldn't see more than a block in either direction due to the clouds of dust that had arisen from buildings that had just collapsed ... From here, we picked up our vehicles from the CCC car park and headed out to get out of the chaos to a position where we could check on loved ones. Heading first along Manchester Street, buildings that were already heavily damaged were now completely written off. We couldn't get much further down Manchester Street so eventually made it to Colombo Street".

The title reads 'Future Christchurch CBD?...' Two people stare at numerous large featureless blocks across the Avon River. One says 'Those buildings look pretty ugly' and the other points out that they are 'just the piles'. Context: The Christchurch City Council is moving to impose urban-design etiquette and avert architectural mistakes such as clashing with the neighbours, glaring corporate colours and the long, blank walls common to most suburban shopping malls. The proposed rules will be overseen by an urban-design panel of four experts drawn from a pool of 12 architects, designers, planners and valuers. Quantity: 1 digital cartoon(s).

The NMIT Arts & Media Building is the first in a new generation of multistorey timber structures. It employs an advanced damage avoidance earthquake design that is a world first for a timber building. Aurecon structural engineers are the first to use this revolutionary Pres-Lam technology developed at the University of Canterbury. This technology marks a fundamental change in design philosophy. Conventional seismic design of multi-storey structures typically depends on member ductility and the acceptance of a certain amount of damage to beams, columns and walls. The NMIT seismic system relies on pairs of coupled LVL shear walls that incorporate high strength steel tendons post-tensioned through a central duct. The walls are centrally fixed allowing them to rock during a seismic event. A series of U-shaped steel plates placed between the walls form a coupling mechanism, and act as dissipators to absorb seismic energy. The design allows the primary structure to remain essentially undamaged while readily replaceable connections act as plastic fuses. In this era where sustainability is becoming a key focus, the extensive use of timber and engineered-wood products such as LVL make use of a natural resource all grown and manufactured within a 100km radius of Nelson. This project demonstrates that there are now cost effective, sustainable and innovative solutions for multi-story timber buildings with potential applications for building owners in seismic areas around the world.
