Some Christchurch residents fear there's a risk to the region's history if headstones damaged by September's 7.1 magnitude earthquake are not repaired.

Victoria Square, the slightly less famous cousin of nearby Cathedral Square was re-opened today following $7.5 million worth of earthquake repairs.
Still awaiting a repair, but with so many bridges closed or partially closed we are lucky this one had what maybe minor damage.

Six years after being severely damaged in the 2011 Christchurch earthquake and after two years of repairs, Mona Vale has reopened its doors to the public.
A Christchurch construction firm says businesses who are complaining about losing money on earthquake repair jobs should work more closely with their project managers.
Two years on from the February twenty second earthquake, large parts of Christchurch Hospital are a construction site as repairs to damaged wards continue.
The owners of more than three-thousand properties damaged by the Canterbury earthquake have been told the repair job could take nearly three years.
Fletcher Construction has won the largest building contract in New Zealand history to repair half of the Canterbury homes damaged in last month's earthquake.
Christchurch council has asked its residents to tell it if earthquake repairs haven't been done so it can accurately assess their property's value.

Time is nearly up for owners of on-sold quake damaged properties in Canterbury to apply to claim money for botched repairs. The Government announced last year it would give an ex-gratia payment to home-owners with properties that went over the Earthquake Commission's then cap of $100,000. Today is the last day for applications after the original August deadline was extended due to Covid-19. But there are calls to extend that deadline again, as applications have flooded in over the past month.
More repairs to the infrastructure as a result of the 2010 & 2011 earthquakes. Hardy Street/Owles Terrace corner (beside the boat launching ramp), New Brighton
One of the most controversial issues highlighted by the 2010-2011 Christchurch earthquake series and more recently the 2016 Kaikoura earthquake, has been the evident difficulty and lack of knowledge and guidelines for: a) evaluation of the residual capacity damaged buildings to sustain future aftershocks; b) selection and implementation of a series of reliable repairing techniques to bring back the structure to a condition substantially the same as prior to the earthquake; and c) predicting the cost (or cost-effectiveness) of such repair intervention, when compared to fully replacement costs while accounting for potential aftershocks in the near future. As a result of such complexity and uncertainty (i.e., risk), in combination with the possibility (unique in New Zealand when compared to most of the seismic-prone countries) to rely on financial support from the insurance companies, many modern buildings, in a number exceeding typical expectations from past experiences at an international level, have ended up being demolished. This has resulted in additional time and indirect losses prior to the full reconstruction, as well as in an increase in uncertainty on the actual relocation of the investment. This research project provides the main end-users and stakeholders (practitioner engineers, owners, local and government authorities, insurers, and regulatory agencies) with comprehensive evidence-based information to assess the residual capacity of damage reinforced concrete buildings, and to evaluate the feasibility of repairing techniques, in order to support their delicate decision-making process of repair vs. demolition or replacement. Literature review on effectiveness of epoxy injection repairs, as well as experimental tests on full-scale beam-column joints shows that repaired specimens have a reduced initial stiffness compared with the undamaged specimen, with no apparent strength reduction, sometimes exhibiting higher displacement ductility capacities. Although the bond between the steel and concrete is only partially restored, it still allows the repaired specimen to dissipate at least the same amount of hysteretic energy. Experimental tests on buildings subjected to earthquake loading demonstrate that even for severe damage levels, the ability of the epoxy injection to restore the initial stiffness of the structure is significant. Literature review on damage assessment and repair guidelines suggests that there is consensus within the international community that concrete elements with cracks less than 0.2 mm wide only require cosmetic repairs; epoxy injection repairs of cracks less and 2.0 mm wide and concrete patching of spalled cover concrete (i.e., minor to moderate damage) is an appropiate repair strategy; and for severe damaged components (e.g., cracks greater than 2.0 mm wide, crushing of the concrete core, buckling of the longitudinal reinforcement) local replacement of steel and/or concrete in addition to epoxy crack injection is more appropriate. In terms of expected cracking patterns, non-linear finite element investigations on well-designed reinforced concrete beam-to-column joints, have shown that lower number of cracks but with wider openings are expected to occur for larger compressive concrete strength, f’c, and lower reinforcement content, ρs. It was also observed that the tensile concrete strength, ft, strongly affects the expected cracking pattern in the beam-column joints, the latter being more uniformly distributed for lower ft values. Strain rate effects do not seem to play an important role on the cracking pattern. However, small variations in the cracking pattern were observed for low reinforcement content as it approaches to the minimum required as per NZS 3101:2006. Simple equations are proposed in this research project to relate the maximum and residual crack widths with the steel strain at peak displacement, with or without axial load. A literature review on fracture of reinforcing steel due to low-cycle fatigue, including recent research using steel manufactured per New Zealand standards is also presented. Experimental results describing the influence of the cyclic effect on the ultimate strain capacity of the steel are also discussed, and preliminary equations to account for that effect are proposed. A literature review on the current practice to assess the seismic residual capacity of structures is also presented. The various factors affecting the residual fatigue life at a component level (i.e., plastic hinge) of well-designed reinforced concrete frames are discussed, and equations to quantify each of them are proposed, as well as a methodology to incorporate them into a full displacement-based procedure for pre-earthquake and post-earthquake seismic assessment.
The Property Council says an ultimatum from the Christchurch City Council to owners of earthquake damaged commercial buildings will add to the stress business people are already under.
EQC was ill-prepared to deal with the wide spread damage of the Christchurch Earthquakes and as a consequence its reputation been left in tatters with many seeing the commission as uncaring, miserly and inefficient. That is according to the findings of the inquiry into EQC and its handling of quake claims in Canterbury and Kaikōura. Inquiry Chair Dame Silvia Cartwright lays out a raft of inadequacies including EQC not being equiped to handle a mass scale managed repair programme - leading to multiple mistakes, poor staffing decisions and inadequate quality control. Damage assessments were the root of claimants disputes time and time again. Dame Silvia Cartwright described to Checkpoint the way claimants have been treated by EQC.
