An outline, created in 2011, of the levels of service and condition of the horizontal infrastructure within the central city, providing a broad indication of damage, service levels provided to residents and business owners, and used to estimate the cost of repairs following the earthquake events.

An aerial photograph of the PricewaterhouseCoopers building. The photograph is captioned by BeckerFraserPhotos, "PricewaterhouseCoopers building at 119 Armagh Street. Its status is uneconomic to repair, so it will be demolished. Copthorne Central is visible behind it and will be staying".

A crane beside the boiler chimney in the University of Canterbury's Facilities Management yard. The photographer comments, "The University restarts its teaching, and the techies in e-learning move out of NZi3. Inspection and repairs to the University's boiler system. It's getting cooler, we'll need heat soon - but we need accessible buildings first".

Buckled columns on a house in Wainoni. The photographer comments, "A Sunday afternoon ride to New Brighton, then back via Aranui, Wainoni, Dallington, and Richmond. Not a cheerful experience. 'We've decided you're a repair, not a rebuild after all'. Actually, I think these houses might be red zoned".

Steel bracing on the front of the Worcester Street face of the Octagon Live Restaurant (formerly Trinity Church), which is being repaired. The scaffolding has been decorated with sculptures of people kayaking, cycling, climbing and bungee jumping. Some of the figures are wearing santa hats. A fence has been constructed at the base of the building.

Crack repairs on the Rendezvous Hotel in Gloucester Street. Cracks have been injected with epoxy resin using syringes. The epoxy resin leaves a peak around each hole which will be ground down to a smooth surface. The wall will then be repainted. This process actually makes the wall stronger than it was originally.

Asset management in power systems is exercised to improve network reliability to provide confidence and security for customers and asset owners. While there are well-established reliability metrics that are used to measure and manage business-as-usual disruptions, an increasing appreciation of the consequences of low-probability high-impact events means that resilience is increasingly being factored into asset management in order to provide robustness and redundancy to components and wider networks. This is particularly important for electricity systems, given that a range of other infrastructure lifelines depend upon their operation. The 2010-2011 Canterbury Earthquake Sequence provides valuable insights into electricity system criticality and resilience in the face of severe earthquake impacts. While above-ground assets are relatively easy to monitor and repair, underground assets such as cables emplaced across wide areas in the distribution network are difficult to monitor, identify faults on, and repair. This study has characterised in detail the impacts to buried electricity cables in Christchurch resulting from seismically-induced ground deformation caused primarily by liquefaction and lateral spread. Primary modes of failure include cable bending, stretching, insulation damage, joint braking and, being pulled off other equipment such as substation connections. Performance and repair data have been compiled into a detailed geospatial database, which in combination with spatial models of peak ground acceleration, peak ground velocity and ground deformation, will be used to establish rigorous relationships between seismicity and performance. These metrics will be used to inform asset owners of network performance in future earthquakes, further assess component criticality, and provide resilience metrics.

Scaffolding that has been constructed on the Manchester Street face of the Octagon Live Restaurant (formerly Trinity Church), which is being repaired. Masonry has fallen from one of the building's gables, and the resultant gap has been weather proofed with plywood and a tarpaulin. The site has been enclosed in a safety fence that cuts off one lane of the road.
