Designing a structure for higher- than-code seismic performance can result in significant economic and environmental benefits. This higher performance can be achieved using the principles of Performance-Based Design, in which engineers design structures to minimize the probabilistic lifecycle seismic impacts on a building. Although the concept of Performance-Based Design is not particularly new, the initial capital costs associated with designing structures for higher performance have historically hindered the widespread adoption of performance-based design practices. To overcome this roadblock, this research is focused on providing policy makers and stakeholders with evidence-based environmental incentives for designing structures in New Zealand for higher seismic performance. In the first phase of the research, the environmental impacts of demolitions in Christchurch following the Canterbury Earthquakes were quantified to demonstrate the environmental consequences of demolitions following seismic events. That is the focus here. A building data set consisting of 142 concrete buildings that were demolished following the earthquake was used to quantify the environmental impacts of the demolitions in terms of the embodied carbon and energy in the building materials. A reduced set of buildings was used to develop a material takeoff model to estimate material quantities in the entire building set, and a lifecycle assessment tool was used to calculate the embodied carbon and energy in the materials. The results revealed staggering impacts in terms of the embodied carbon and energy in the materials in the demolished buildings. Ongoing work is focused developing an environmental impact framework that incorporates all the complex factors (e.g. construction methodologies, repair methodologies (if applicable), demolition methodologies (if applicable), and waste management) that contribute to the environmental impacts of building repair and demolition following earthquakes.

A Christchurch homeowner in a five year battle with the Earthquake Commission over the damaged house she unwittingly bought says a critical new report about EQC tells her nothing new. The 27 page review by Independent Ministerial Advisor Christine Stevenson looks at how to resolve the 3,600 claims that still haven't been settled after the 2010 and 2011 quakes. The recommendations include getting the Commission to hire more staff and to stop forcing people to use the Official Information Act to get their files. It also suggests giving EQC more power to settle the on-sold claims where people bought houses under the impression all damage had been identified and fixed. Georgina Hannafin has a home that needs $260,000 worth of repairs but EQC has offered her just $48,000.
Southern Response is back in court today - this time having a final go at arguing that a class action against it should not be an 'opt-out'. Christchurch residents Brendan and Colleen Ross say the state insurer deliberately withheld the true cost of repairing their home which was damaged in the Canterbury earthquakes. They are now among 3000 people represented in a class action led by Christchurch lawyer Grant Cameron. In September last year the Court of Appeal decided the class action could proceed on an 'opt-out' basis - which means it would cover more people and potentially cost the state-owned insurer more money if it loses. Southern Response is challenging that decision in the Supreme Court, a two day hearing wrapped up on Tuesday. Checkpoint reporter Logan Church was there.
Media law developments have continued across many areas in the period to mid-2013. In defamation, the New Zealand courts have begun to consider the issue of third party liability for publication on the internet, with cases involving Google searches and comments on a Facebook page. A parliamentary inquiry into a case that restricted parliamentary privilege has recommended a Parliamentary Privilege Act containing a definition of ‘proceedings in Parliament’. A satirical website increased its popularity when it fought off threatened defamation proceedings. In breach of confidence, a government body, the Earthquake Commission, obtained an interim injunction prohibiting publication of information accidentally released that dealt with the repair of earthquake-damaged properties in Christchurch, and a blogger made the information available online in breach of the order.

Observations made in past earthquakes, in New Zealand and around the world, have highlighted the vulnerability of non-structural elements such as facades, ceilings, partitions and services. Damage to these elements can be life-threatening or jeopardise egress routes but typically, the main concern is the cost and time associated with repair works. The Insurance Council of New Zealand highlighted the substantial economic losses in recent earthquakes due to poor performance of non-structural elements. Previous inspections and research have attributed the damage to non-structural elements principally to poor coordination, inadequate or lack of seismic restraints and insufficient clearances to cater for seismic actions. Secondary issues of design responsibility, procurement and the need for better alignment of the various Standards have been identified. In addition to the compliance issues, researchers have also demonstrated that current code provisions for non-structural elements, both in New Zealand and abroad, may be inadequate. This paper first reviews the damage observed against the requirements of relevant Standards and the New Zealand Building Code, and it appears that, had the installations been compliant, the cost of repair and business interruption would have been substantially less. The second part of the paper highlights some of the apparent shortcomings with the current design process for non-structural elements, points towards possible alternative strategies and identifies areas where more research is deemed necessary. The challenge of improving the seismic performance of non-structural elements is a complex one across a diverse construction industry. Indications are that the New Zealand construction industry needs to completely rethink the delivery approach to ensure an integrated design, construction and certification process. The industry, QuakeCentre, QuakeCoRE and the University of Canterbury are presently working together to progress solutions. Indications are that if new processes can be initiated, better performance during earthquakes will be achieved while delivering enhanced building and business resilience.

We measure the longer-term effect of a major earthquake on the local economy, using night-time light intensity measured from space, and investigate whether insurance claim payments for damaged residential property affected the local recovery process. We focus on the destructive Canterbury Earthquake Sequence (CES) 2010 -2011 as our case study. Uniquely for this event, more than 95% of residential housing units were covered by insurance, but insurance payments were staggered over 5 years, enabling us to identify their local impact. We find that night-time luminosity can capture the process of recovery and describe the recovery’s determinants. We also find that insurance payments contributed significantly to the process of economic recovery after the earthquake, but delayed payments were less affective and cash settlement of claims were more effective than insurance-managed repairs in contributing to local recovery.
A crowd of Christchurch rugby fans wearing the red and black colours, gather to wish the Crusaders well as they leave for Australia. Someone shouts 'Red and black... It's one zone we ALL belong in!' Context - The Reds (Queensland) and Crusaders (Christchurch) played on the 11th July in the Final of the Investec Super Rugby competition at Suncorp Stadium, Brisbane. The Crusaders were narrowly beaten 18-13. The comment referring to 'one zone' relates to the dividing Christchurch, after the earthquakes, into zones labelled with different colours that indicates whether buildings have to be removed, or can be repaired or whether a decision has yet to be made or they are ok.

Christchurch City has to be rebuilt after the earthquakes of 4 September 2010 and 22 February 2011. People are being invited to contribute ideas about how to rebuild on a city council website. A group of people look at ideas on computers; a boy comments that 'this one looks just like the old city' and his father comments 'but built fifty miles up the road!' A woman looks at what appears to be pre European Maori pa site and says 'Hone Harawira wants something pre-European!' Another woman looks at a map of the middle of the South Island and says 'Rodney Hide doesn't care as long as Christchurch combines with Timaru and Westport!' Context - Former ACT leader Rodney Hide in his role as Minister for Local Government likes 'supercities' and Hone Harawira has left the Maori Party, fed up with the compromises he believes they have to make to suit their coalition agreement with the National government. He seems to prefer a city that will reflect simpler pre-European times. Colour and black and white versions available Quantity: 2 digital cartoon(s).
Refers to the controversy over the decision to demolish the Christchurch Cathedral which was severely damaged in the earthquakes of 2010 and 2011. The Anglican Bishop of Christchurch Victoria Mathews says the decision to demolish the cathedral was reached through prayer, great deliberation and with the utmost concern for safety. The Bishop says a number of options were considered before deciding to bring the walls down but the turning point was 23 December 2011, when a series of strong quakes rocked the city. At that stage the Canterbury Earthquake Authority approached the church. "CERA told us that our plans for making safe and retrieving, and then stepping back and making further decisions were no longer adequate." Christchurch City council announced their support on Twitter this afternoon (17 May 2012) - tweeting an endorsement to an immediate pause on demolition of the Cathedral to enable deeper and more open consideration of options.

essential systems upon which the well-being and functioning of societies depend. They deliver a service or a good to the population using a network, a combination of spatially-distributed links and nodes. As they are interconnected, network elements’ functionality is also interdependent. In case of a failure of one component, many others could be momentarily brought out-of-service. Further problems arise for buried infrastructure when it comes to buried infrastructure in earthquake and liquefaction-prone areas for the following reasons: • Technically more demanding inspections than those required for surface horizontal infrastructure • Infrastructure subject to both permanent ground displacement and transient ground deformation • Increase in network maintenance costs (i.e. deterioration due to ageing material and seismic hazard) These challenges suggest careful studies on network resilience will yield significant benefits. For these reasons, the potable water network of Christchurch city (Figure 1) has been selected for its well-characterized topology and its extensive repair dataset.

Rocket Lab's Electron rocket launch today on the Mahia Peninsula has been scrubbed again, sadly. A power fault this time. Kaikoura residents and businesses are celebrating the re-opening of State Highway 1 north following a year of earthquake repairs. The coastal highway link between Picton and Christchurch was badly damaged during the November 2016 quake but will now re-open during the day from 7am. It will close at 8:30 each night so more repairs and assesments can be done. Kaikoura Top Ten Holiday Park co-owner Ed Nolan tells us what this means for his business and others in the town. The Prime Minister Jainda Ardern says the Government's new families package will reduce child poverty in the country by 48 per cent. We ask the panellists whether this is realistic or if there are other, more entrenched imprediments to lowering poverty in New Zealand. The panellists also discuss the state of the books, and discuss if they worry about national debt iincreasing, as the opposition has warned. The Prime Minister says wealthy New Zealanders can opt out of the Government's Winter Energy Payment, which will see those on a benefit, NZ Superannuation or a Veterans Pension get an extra boost due the winter season. Many are doubtful that will happen though. The panellists discuss why some wealthy people have missed out on tax cuts only to be able to reap the reward of this package. We also ask if they suspect this money will be used for heating purposes. The University of Otago has a new degree which brings science and art together, the BaSc. It aims to break down barriers between the two disciplines. Two students are graduating the degree this week. We talk to Eirenie Taua'i who has been studying Pacific Studies and Neuroscience. We aslk her what careers she is considering now and what it was like to study to very different courses. The families of those who died in the CTV building collapse in Christchurch's 2011 earthquake say they will continue to fight for justice. Police announced earlier this month they won't be prosecuting the engineers of the building after a three-year long investigation. The families met with police to ask and why say they aren't convinced all has been done. We ask panellist, barrister Jonathan Krebs, if other charges could and should be laid.
A poster created by Empowered Christchurch to advertise their submission to the CERA Draft Transition Recovery Plan on social media.The poster reads, "Submission. CERA Draft Transition Recovery Plan. 5. In your opinion, is there a better way to report on these recovery issues? We believe that, as regards residential recovery, monitoring should extend to code compliance certificates. According to figures published in 2014, only factions of repairs/rebuilds are completed with the issue of a code compliance certificate. To conclude the work to the required standard, someone must pay for the code compliance. Leaving things as they are could have serious negative consequences for the recovery and for the city as a whole. We suggest an investigation of number of outstanding code compliance certificates and that responsible parties are made to address this outstanding work. We need a city that is driven by the people that live in it, and enabled by a bureaucracy that accepts and mitigates risks, rather than transferring them to the most vulnerable residents."
A review of the week's news including... The bill to fix botched EQC repairs from the Canterbury earthquakes is now four times what the previous Government predicted just two years ago, immigrants are being computer profiled, MPs are told that medicinal cannabis should be legalised for more people, Middlemore Hospital's woes continue, the Government orders a compulsory recall of 50 thousand vehicles with faulty airbags, Auckland drivers face a double tax hike under proposed sweeping changes to transport funding, Parliament changes the law so New Zealand men with historical homosexual convictions can have them wiped, a bus company wants to recruit more than 100 drivers from overseas because it can't find enough people to do the job here, Dunedin has its biggest weekend ever in terms of money spent thanks to Ed Sheeran, first it was closing - now it's not, Kaikohe's Warehouse is to stay, it all comes together for the New Zealand cricket team against England, an international consortium reaches a verbal agreement to buy the New Zealand Warriors and the woman who was RNZ's Washington correspondent for more than 20 years has died.
The Christchurch region of New Zealand experienced a series of major earthquakes and aftershocks between September 2010 and June 2011 which caused severe damage to the city’s infrastructure. The performance of tilt-up precast concrete buildings was investigated and initial observations are presented here. In general, tilt-up buildings performed well during all three major earthquakes, with mostly only minor, repairable damage occurring. For the in-plane loading direction, both loadbearing and cladding panels behaved exceptionally well, with no significant damage or failure observed in panels and their connections. A limited number of connection failures occurred due to large out-of-plane panel inertia forces. In several buildings, the connections between the panel and the internal structural frame appeared to be the weakest link, lacking in both strength and ductility. This weakness in the out-of-plane load path should be prevented in future designs.
Following the 2010/2011 Canterbury, New Zealand earthquakes, a detailed door-to-door survey was conducted in the Christchurch region to establish the earthquake performance of lightweight timber-framed residential dwellings with a masonry veneer external cladding system. The post-earthquake survey involved documenting the condition of dwellings in areas that had experienced different levels of earthquake shaking, allowing comparison between the performance of different veneer systems and different shaking intensities. In total, just fewer than 1,100 residential dwellings were inspected throughout the wider Christchurch area. The survey included parameters such as level of veneer damage, type of veneer damage, observed crack widths, and level of repair required. It is concluded that based on observed earthquake performance at the shaking intensities matching or exceeding ultimate limit state loading, the post-1996 veneer fixing details performed satisfactorily and continued use of the detail is recommended without further modification.

Under the caption 'Best value for money?' is a football stadium displaying a red cross. From within a voice proclaims the advantages of having a combined covered stadium, hospital and blood bank. Under CERA, the Christchurch Central Development Unit had planned for a covered sports stadium, with attached facilities and shops as one of the key sites in the Christchurch rebuild after the 2010 and 2011 earthquakes. The 'blood bin' refers to the recent practice in rugby of sending off players with flesh wounds. There were also plans for a new hospital. Quantity: 1 digital cartoon(s).
The Canterbury earthquakes in 2010 and 2011 had a significant impact on landlords and tenants of commercial buildings in the city of Christchurch. The devastation wrought on the city was so severe that in an unprecedented response to this disaster a cordon was erected around the central business district for nearly two and half years while demolition, repairs and rebuilding took place. Despite the destruction, not all buildings were damaged. Many could have been occupied and used immediately if they had not been within the cordoned area. Others had only minor damage but repairs to them could not be commenced, let alone completed, owing to restrictions on access caused by the cordon. Tenants were faced with a major problem in that they could not access their buildings and it was likely to be a long time before they would be allowed access again. The other problem was uncertainty about the legal position as neither the standard form leases in use, nor any statute, provided for issues arising from an inaccessible building. The parties were therefore uncertain about their legal rights and obligations in this situation. Landlords and tenants were unsure whether tenants were required to pay rent for a building that could not be accessed or whether they could terminate their leases on the basis that the building was inaccessible. This thesis looks at whether the common law doctrine of frustration could apply to leases in these circumstances, where the lease had made no provision. It analyses the history of the doctrine and how it applies to a lease, the standard form leases in use at the time of the earthquakes and the unexpected and extraordinary nature of the earthquakes. It then reports on the findings of the qualitative empirical research undertaken to look at the experiences of landlords and tenants after the earthquakes. It is argued that the circumstances of landlords and tenants met the test for the doctrine of frustration. Therefore, the doctrine could have applied to leases to enable the parties to terminate them. It concludes with a suggestion for reform in the form of a new Act to govern the special relationship between commercial landlords and tenants, similar to legislation already in place covering other types of relationships like those in residential tenancies and employment. Such legislation could provide dispute resolution services to enable landlords and tenants to have access to justice to determine their legal rights at all times, and in particular, in times of crisis.
The cartoon shows Prime Minister John Key as a surgeon in a blood-spattered white coat; he has just created a Frankenstein monster which has resulted in the Minister for Earthquake Recovery Gerry Brownlee and Mayor of Christchurch Bob Parker joined together in a single body named 'CERA". Gerry Brownlee clutches a huge spiked mallet and Bob Parker a paintbrush. Context - a new bill is being rushed through parliament to establish the Canterbury Earthquake Recovery Authority (Cera); it empowers it to lead reconstruction efforts in Christchurch. It gives Cera specific powers to get information from any source, to requisition and build on land and to carry out demolitions. It can also take over local authorities if they are not working effectively on recovery work. The monster suggests distinctly differing philosophies on how the work of rebuilding Christchurch should proceed. Quantity: 1 digital cartoon(s).
A Christchurch couple locked in an ongoing legal battle with state-owned quake insurer Southern Response says it is sobering for a Court of Appeal decision to go their way, one decade on from the harrowing earthquakes. An earlier High Court decision found Southern Response guilty of misleading and deceptive behaviour when it short-changed Karl and Alison Dodds tens of thousands of dollars after their quake damaged house was written off. The Dodds say they were tricked into accepting a lower offer from Southern Response only to later discover the insurer had kept secret from them a second higher estimate to rebuild their damaged house, a so-called second secret detailed repair and rebuild analysis (DRA). The High Court ordered Southern Response to pay the Dodds almost $180,000 in damages, plus costs. But the government appealed the decision, saying it needed clarity, because of the thousands of similar cases it could be liable for. The Court of Appeal reduced the damages Southern Response has to pay $10,656.44 due to an earlier error in calculations. The Minister responsible Grant Robertson has declined to be interviewed. Southern Response also declined to be interviewed. Neither have ruled out appealing the decision in the Supreme Court.
In the aftermath of the 2010-2011 Canterbury earthquakes in New Zealand, the residual capacity and reparability of damaged reinforced concrete (RC) structures was an issue pertinent to building owners, insurers, and structural engineers. Three precast RC moment-resisting frame specimens were extracted during the demolition of the Clarendon Tower in Christchurch after sustaining earthquake damage. These specimens were subjected to quasi-static cyclic testing as part of a research program to determine the reparability of the building. It was concluded that the precast RC frames were able to be repaired and retrofitted to an enhanced strength capacity with no observed reduction in displacement capacity, although the frames with “shear-ductile” detailing exhibited less displacement ductility capacity and energy dissipation capacity than the more conventionally detailed RC frames. Furthermore, the cyclic test results from the earthquake-damaged RC frames were used to verify the predicted inelastic demands applied to the specimens during the 2010-2011 Canterbury earthquakes. https://www.concrete.org/publications/acistructuraljournal.aspx
In this thesis, focus is given to develop methodologies for rapidly estimating specific components of loss and downtime functions. The thesis proposes methodologies for deriving loss functions by (i) considering individual component performance; (ii) grouping them as per their performance characteristics; and (iii) applying them to similar building usage categories. The degree of variation in building stock and understanding their characteristics are important factors to be considered in the loss estimation methodology and the field surveys carried out to collect data add value to the study. To facilitate developing ‘downtime’ functions, this study investigates two key components of downtime: (i) time delay from post-event damage assessment of properties; and (ii) time delay in settling the insurance claims lodged. In these two areas, this research enables understanding of critical factors that influence certain aspects of downtime and suggests approaches to quantify those factors. By scrutinising the residential damage insurance claims data provided by the Earthquake Commission (EQC) for the 2010- 2011 Canterbury Earthquake Sequence (CES), this work provides insights into various processes of claims settlement, the time taken to complete them and the EQC loss contributions to building stock in Christchurch city and Canterbury region. The study has shown diligence in investigating the EQC insurance claim data obtained from the CES to get new insights and build confidence in the models developed and the results generated. The first stage of this research develops contribution functions (probabilistic relationships between the expected losses for a wide range of building components and the building’s maximum response) for common types of claddings used in New Zealand buildings combining the probabilistic density functions (developed using the quantity of claddings measured from Christchurch buildings), fragility functions (obtained from the published literature) and cost functions (developed based on inputs from builders) through Monte Carlo simulations. From the developed contribution functions, glazing, masonry veneer, monolithic and precast concrete cladding systems are found to incur 50% loss at inter-storey drift levels equal to 0.027, 0.003, 0.005 and 0.011, respectively. Further, the maximum expected cladding loss for glazing, masonry veneer, monolithic, precast concrete cladding systems are found to be 368.2, 331.9, 365.0, and 136.2 NZD per square meter of floor area, respectively. In the second stage of this research, a detailed cost breakdown of typical buildings designed and built for different purposes is conducted. The contributions of structural and non- structural components to the total building cost are compared for buildings of different usages, and based on the similar ratios of non-structural performance group costs to the structural performance group cost, four-building groups are identified; (i) Structural components dominant group: outdoor sports, stadiums, parkings and long-span warehouses, (ii) non- structural drift-sensitive components dominant group: houses, single-storey suburban buildings (all usages), theatres/halls, workshops and clubhouses, (iii) non-structural acceleration- sensitive components dominant group: hospitals, research labs, museums and retail/cold stores, and (iv) apartments, hotels, offices, industrials, indoor sports, classrooms, devotionals and aquariums. By statistically analysing the cost breakdowns, performance group weighting factors are proposed for structural, and acceleration-sensitive and drift-sensitive non-structural components for all four building groups. Thus proposed building usage groupings and corresponding weighting factors facilitate rapid seismic loss estimation of any type of building given the EDPs at storey levels are known. A model for the quantification of post-earthquake inspection duration is developed in the third stage of this research. Herein, phase durations for the three assessment phases (one rapid impact and two rapid building) are computed using the number of buildings needing inspections, the number of engineers involved in inspections and a phase duration coefficient (which considers the median building inspection time, efficiency of engineer and the number of engineers involved in each assessment teams). The proposed model can be used: (i) by national/regional authorities to decide the length of the emergency period following a major earthquake, and estimate the number of engineers required to conduct a post-earthquake inspection within the desired emergency period, and (ii) to quantify the delay due to inspection for the downtime modelling framework. The final stage of this research investigates the repair costs and insurance claim settlement time for damaged residential buildings in the 2010-2011 Canterbury earthquake sequence. Based on the EQC claim settlement process, claims are categorized into three groups; (i) Small Claims: claims less than NZD15,000 which were settled through cash payment, (ii) Medium Claims: claims less than NZD100,000 which were managed through Canterbury Home Repair Programme (CHRP), and (iii) Large Claims: claims above NZD100,000 which were managed by an insurance provider. The regional loss ratio (RLR) for greater Christchurch for three events inducing shakings of approximate seismic intensities 6, 7, and 8 are found to be 0.013, 0.066, and 0.171, respectively. Furthermore, the claim duration (time between an event and the claim lodgement date), assessment duration (time between the claim lodgement day and the most recent assessment day), and repair duration (time between the most recent assessment day and the repair completion day) for the insured residential buildings in the region affected by the Canterbury earthquake sequence is found to be in the range of 0.5-4 weeks, 1.5- 5 months, and 1-3 years, respectively. The results of this phase will provide useful information to earthquake engineering researchers working on seismic risk/loss and insurance modelling.
